AIHE State President’s Meeting was held on 15th of March at Grand Hyatt, Melbourne. The major topic was the final touch-up for the upcoming conference in August. We also discussed about sponsoring hotel engineers to the conference from different states.

NEW SOUTH WALES

G

reetings from NSW Chapter

We have reached the first part of the mildest time of year, Autumn.

In Sydney we experienced a huge hail storm and are now getting ready for another cold winter. So, it would be a great challenge for the hotel engineers to keep their buildings warm.

The year 2019 has been a great success leading up to March. I would like to welcome all the new members of NSW Chapter and thank those who have contributed to the success of the chapter.

The chapter is growing day by day and it seems like we will have a very prosperous journey in 2019.

The NSW Chapter made a kick start to the year, on 23rd January with our first committee meeting at the Blu Bar in Shangri-La Hotel, Sydney. The meeting was a success where we prepared the event calendar for the year. I would like to appreciate everyone who attended the meeting, especially with Trevor McCarran’s presence.

Our first general meeting for the year was held in February at The Grace Hotel, Sydney. It was another successful round table discussion. Andrew Allen, hotel manager of Grace Hotel, opened the meeting with an encouraging speech about the value of Hotel Engineers and how important the cost savings are, especially during this challenging environment. Thanks go to Andrew Yap, the hotel Engineer for organising the venue.

In 27th March, we had our second monthly meeting for NSW Chapter which was held in Swissotel, Sydney. Steve Powell, Principal Corrosion Engineer/ Risk Management Consultant & Sami Joe El-Kouba, Corrosion Engineer from IMC (Independent Monitoring Consultants) did the presentation on “Practical Aspects of Legionella Control and Non Destructive Testing in the HVAC Industry”. The presentation was very interesting and it was an educational session for all of us.

Moving forward, on 17th of April we will have a breakfast meeting at TAA NSW Office. The presentation will be on ‘Environmental Planning and Assessment Amendment (Fire Safety and Building Certification) implemented 1st October

2017’, by Trevor Burrows the Compliance Manager from Australian Essential Services Compliance (AESC). This will be an ideal topic as most of the engineers require insight and clarification on this area.

I would like to take this opportunity to thank Carol Giuseppi the outgoing CEO of TAA NSW for her excellent contribution to the Hotel industry.

Looking forward to seeing a great attendance at the AIHE conference being held on the 15th & 16 August 2019 at QT Surface Paradise, Gold Coast.

In closing, I would like to express my appreciation to all committee members, all Engineers and our corporate members and various Hotel General Managers for their support over the past year and look forward to another great quarter.

Best Regards Anura Yapa JP President – AIHE NSW chapter

warm welcome from Western Australia

After a well-earned break the WA Chapter had its first meeting at the Empire Bar which is located on Great Eastern Hwy. Our guest presenter was Daryl Brett, Director of Sales from Vintech. Daryl’s main presentation was about the Dormakaba lodging systems and he also focused on new technology such as Bluetooth and room management systems.

Daryl also presented on a wide range of automatic operators, revolving doors and Greelex bi-folding operators.

The meeting was well received with over 40 members that attended, and was followed with refreshments and a supper.

A big thank you to Daryl and Vintech.

In March we held a members with partners sundowner event at the Camfield which attracted over 50 people. All food and drinks were provided and with a barmy night of 21°C it made for a great networking evening which was enjoyed by all.

Our events calendar is booked out now – so we are looking forward to a very busy year.

In finishing, we are all very excited in Western Australia to see you all at the conference on the Gold Coast this year in August.

NEW LANDMARK

REACHES PERTH'S PINNACLE

Western Australia welcomes its first DoubleTree by Hilton and Australia’s first new-build DoubleTree property

11

A

s the popularity and vibrancy of Perth continues to grow, a new brand in the hotel market is quickly making its mark. DoubleTree by Hilton Perth Northbridge is the brand’s first property in Western Australia, and its first new build property to open in the country. Since its opening in December 2018, the stylish accommodation option has been a hit with guests, who enjoy the city’s Northbridge precinct on their doorstep, complete with restaurants, shopping and culture nearby. It is an imposing 15-level, full service hotel on 1666sqm of land. Now a quickly recognisable landmark on James Street, DoubleTree by Hilton Perth Northbridge is comfortably the tallest building in the area with panoramic views from most rooms.

GROUND-BREAKING GUEST EXPERIENCE Not only is the new build exciting for guests looking for the most modern amenities, it is also a treasure chest of the latest technology. Leading the way in this regard is the collaboration between the hotel’s BMS and Guest Room Management System (GRMS). Believed to be the first of its kind in Australia, the two systems work side by side to maximise guest comfort and operational efficiency. The individual preferences of each guest are recorded in the system, and used to modify a wide range of settings.

Gerard Johnston is Chief Engineer of both DoubleTree by Hilton Perth Northbridge and Parmelia Hilton Perth managing a highly experienced engineering team.

Space is precious.

Create more.

Geberit's trusted space-saving solutions for high rise projects are underpinned by Swiss innovation, precision and quality allowing for more extensive creative freedom.

Our sophisticated sanitary and drainage solutions are proven to not only create more space, but to minimise costs without compromising on quality.

“The GRMS manages lighting, air-conditioning and the comfort of guests” says Gerard. “When a guest returns on their next visit, we can pre-set the room to the previous settings. The lights will automatically turn off after the guest has left the room for 20 minutes. The air conditioner drops to 20 per cent.

Then, when the guest comes back into the building, the room will return to how it was when they left.”

Not only does this save an abundance of power otherwise wasted on an empty room, it also provides operational benefits for the housekeeping department.

“Instead of working floor by floor, the housekeepers can attend rooms based on when guests have left, and they can also remotely monitor if room service has been requested, or if a guest would rather not be disturbed. If a guest is in the room and requested service, the housekeepers will know to knock on the door first, and can greet the guest by name. A portal on each housekeeper’s trolley relays this information.”

Such is the power of the GRMS, it even flags when a guest may not like the room they have been assigned. For example, if a guest has previously stayed near the hotel’s lift or stairwell and found it unsatisfactory, the hotel can offer to change where they stay in advance. These features combine to create an outstanding guest experience.

Honeywell has been an integral part of the build. With the help of subcontractors, the company supplied the television systems, security, BMS and GRMS. Gerard says the relationship between the Hilton and Honeywell has been exceptional, with the system

proving to be essentially fail-proof. 220 monitors are installed in the structure to ensure everything runs smoothly.

“A daily health check of the building is produced each night,” Gerard says. “This tracks everything from water usage to data

and energy consumption. It also means we can see any warning signs for problems early.�

The highly advanced and automated system also reduces the number of engineering staff required to operate the property efficiently. The reception team is also trained in using the system, and are able to respond to reports and alarms accordingly.

These initiatives form part of Hilton’s 2030 Travel with Purpose Goals, committing to doubling investment in social impact and cutting its environmental footprint in half by reducing carbon emissions by 61%, sending zero soap to landfill and lots more.

BATHROOM PODS Another impressive feature of the build has been the prefabricated bathrooms. Perth-based company Pindan designed and constructed the bathrooms in their entirety off site, before the finished pods were craned into Pindan’s $2.6m project installed 202 bathrooms, with each taking 16 days to construct. Gerard says there was not a single broken tile or glass during installation; something he describes as a truly incredible success. This method proved to deliver bathrooms of higher quality, in a quicker period, with less noise disruption compared to building on site.

Four main design considerations were taken into account.

The solid structure had to minimise the risk of cracking and internal damage during transport and lifting, the difference between floor levels was to be reduced during installation, a lifting method allowing for better efficiency was adopted, and the finish was to be of the highest quality. Pindan says being a local manufacturer helped set the company apart from

competitors in China and Thailand, as regular inspections could be conducted with ease.

Reece supplied luxury parts for the bathrooms. Chrome Grohe and Posh shower rails and mixers were installed, along with Roca counter basins and toilets and Geberit dual flush plates.

Roca Virgina freestanding baths are also seen throughout the hotel. Reece says working with an overseas-based interior design firm posed a challenge, as it had to specify products complying with Australian standards. The company says the chosen brands closely align with the DoubleTree brand standards.

Rheem was responsible for the hot water, which includes 12 instantaneous hot water systems and four large storage tanks.

Carrier air conditioners and chillers are installed throughout the hotel.

NETWORK SYSTEMS The hotel makes extensive use of Bluetooth and its online network. A guest’s mobile phone doubles as a room key, thanks to the Bluetooth-enabled smart locks installed throughout the premises.

Digital Key is a feature within the Hilton Honors app, providing the loyalty program's members more choice and control over their entire travel experience. Digital Key gives frequent guests the option to bypass the hotel check-in counter and access their rooms, as well as any other area of the hotel that requires a key, directly via the Hilton Honors app on their smartphones.

A hardened, Cisco Layer 3 network is used. It combines with enterprise-level firewall protection, and air gapped networks with secure port tunnelling. This allows for customised cross communication.

The hotel’s WiFi uses Ruckus BeamFlex Antenna Technology.

This is an omnidirectional technology enabling the WiFi to continually sense and optimise performance for its environment, while also reducing energy usage. The system mitigates radio interference, noise and network performance issues. The wireless LAN is 802.11ac enabled ‘Wave 2’ technology, which supports higher speeds and better performance across the network. With more guests using data-heavy devices, the shift to ‘Wave 2’ from ‘Wave 1’ is a significant enhancement for the hotel. Digital signage around the hotel is supplied by Four Winds Interactive.

VINTAGE FOUNDATIONS The hotel took two-and-a-half years to build. It was constructed on the old Bankwest site branch. The owner of the building, SKS Group, faced the challenge of repiling the foundations, before adding a further 15 stories on top. Local builder Cooper & Oxley performed the forward works.

SKS Group has now embarked on another new hotel. The full service DoubleTree by Hilton Perth Waterfront will be managed

by Hilton under a management agreement with SKS. The hotel is due for completion early next year. With two restaurants and

16

two bars, plus panoramic views of Swan River and the city’s skyline, the 18-level development will be a fine addition to the brand’s portfolio.

The combination of cutting edge technology and excellent staff training with the hotel’s system makes DoubleTree by Perth Hilton Northbridge a leader in Australian hospitality. The investment into the hotel’s features, and positive relationship with suppliers and subcontractors, has the property in an outstanding position going forward. It leads the way for a truly personalised guest experience, and will likely set the tone for how other hotels operate in the future.

Can an

AI-POWERED

messaging platform transform the guest experience?

BRENDON GRANGER I DIRECTOR, TECHNOLOGY4HOTELS

As travel becomes increasingly mobile-centric, hotels have begun utilising mobile apps to drive loyalty and guest engagement. In reality, a lot of hotel guests just aren’t engaging with them. Just think, how many hotel apps do we all have on our phones, and how many do we actually use?

A

ccording to Google, 53% of smartphone users haven’t even installed their favourite brands app, so it’s reasonable to assume that all but the most loyal guests are not using a hotel app during their stay.

With that in mind, here are some of the top considerations with regards to a guest request system.

A lot of hotels still utilise SMS as a way to message guests. While more convenient than downloading an app, SMS can involve additional costs, which are especially high for anyone travelling internationally.

Respecting your guests by NOT asking them to download an app that takes time and uses up valuable space on a person’s smartphone is key to having guests interact with a Guest Request System. A hassle-free experience is a major selling point when trying to encourage guests to interact with your hotel before, during, and after their stay. Especially since most apps are deleted within a week of their last use.

The future of guest communication, therefore, relies on offering a platform that’s free and simple to use. This article expands on what I believe to be the key features in any such platform and when evaluating any such product, I believe these features need to be considered.

WHAT MAKES A GREAT AUTOMATED GUEST REQUEST SYSTEM? Artificial intelligence is the key to offering instant responses to guest requests. Done well, it can truly enhance the guest experience.

Chatbots are what the guest interacts with and the AI running in the background can receive and answer a guests question and if need be, allocate a task to hotel personnel. A question like – “What time is breakfast?” can be instantly answered by the Chatbot. Guest requests such as additional fresh towels, an adapter for their smartphone, or ordering cocktails while lounging by the pool are all seamlessly allocated to the appropriate department using the “smarts” of AI. Ideally, such a platform can be used both on and off the property. So if a guest wants to make a reservation for dinner before arriving, they can do that from anywhere, all via their mobile device.

18

NO NEED FOR DOWNLOADS

HOW WOULD IT WORK? Find a solution that is designed to sit on, or integrate with, any platform. From iOS to android, your hotel’s website, existing hotel applications, or even the in-room television. We all know technology is only as useful as its uptake, so providing a system that is accessible in multiple environments is critical to driving guest usage. Solutions such as progressive web applications, which look and feel like an application, but are deployed via a URL, allows for a Guest Request system that can reside on a website, form part of a guests reservation confirmation email, or can even be accessed at reception, the pool or a room via a QR code. Such flexibility provides a significant advantage.

HOW TO MAKE SURE IT’S THE RIGHT TYPE OF AI There’s AI and there’s AI and people who are human will be interacting with it. Take the time to ensure that the AI is built on Natural Language Processing technology. Natural Language Processing not only understands words and sentences; it’s able to grasp the context of requests and questions. As a result, guests can communicate more easily and receive the

information they’re really looking for, while interactions have the natural patter of a human-like conversation. For example, a well-programmed chatbot will recognise that “I need a toothbrush please” and “I forgot my toothbrush” both represent a guest’s request for another toothbrush.

F&B REQUESTS FROM ANYWHERE = INCREMENTAL REVENUE Incremental revenue is key so ensure that any system will allow guests to see your room service menu and place orders both on and off-property. So if they want to request room service while lounging in bed, or order their evening meal while travelling back to your hotel, all it takes is a tap of a button on their smartphone. This anywhere/anytime convenience makes life easier for guests, and a built-in upsell mechanism also offers hotels a way to generate additional F&B revenue.

MULTI-LINGUAL FUNCTION Look for a system with multi-lingual functionality, where overseas guests can use their mobile to communicate with the hotel in their native language. This eliminates the frustrations that arise from language barriers, making for more satisfying guest experience. In addition, hotels can reduce the associated costs of having to train or recruit staff to communicate in other languages. But be careful, many chatbots solely use Google translate for this functionality. And while this may represent an improvement on no translation capabilities, a solution that can provide fully controlled responses in line with your brand language is preferable.

PROMOTIONS AND OFFERS Ensure that your guests can use their mobile to browse and access all the promotions and offers that your property is running. Ideally select a system that accommodates “push notifications” with pre-programmed content, such as promoting a discount on a luxury spa treatment. I recommend looking for a system that can track and report on uptake of offers to help monitor effectiveness and tailor future marketing efforts.

CONCLUSION Travellers increasingly want their hotel stay to revolve around freedom, flexibility, and convenience. Having a bespoke chat bot instantly available on their own smartphone is a big step in the right direction.

Rather than trying to persuade guests to download an app or chat via SMS, look for a platform that offers a free and frictionless way for them to communicate with the hotel before, during, and after their stay.

CCTV

SIMON HENSWORTH BSC (SECURITY SCIENCE) (ICCP-ADVANCED) SECURITY CONSULTING GROUP (SCG)

CCTV is widely used throughout the Hospitality Industry and can be an important element in the integrated Security Management System.

I

nterest in CCTV has had a recent resurgence due to media attention regarding potential security risks posed by certain camera makes originating from other countries.

The ABC recently ran a report which looked into potential risks associated with CCTV cameras, and a new Bill was recently signed into law in the USA which has included the banning of certain CCTV manufacture types by US agencies. This has created a lot of interest and debate.

POTENTIAL RISKS A couple of years ago there was some negative press regarding a certain manufacturer’s cameras due to the ability for hackers to access camera settings using default passwords. This had allowed a hacker to change settings on the cameras and access camera images, however, this requires that the camera is connected to the Internet in order to provide remote access. Once this issue had been highlighted, the manufacturer of this camera type addressed the issue to prevent an ongoing risk. Regardless of this, as the name suggests, a CCTV system (closed circuit television system) should be operating on a “closed circuit” and not be open to access via a wider or interconnected network. In some instances, CCTV systems do end up on business networks that are open to the internet, or for operational reasons are connected to wider networks to be available remotely, however, these should undergo the same levels of logical security as any other critical business system, and therefore should be configured to prevent unauthorised access.

There was another case a few years ago where a large number of CCTV cameras (in the thousands) were accessed by unauthorised individual/s and configured to assist in a Distributed Denial of Service Attack (DDOS) against some well-known websites. This managed to take these websites down for a number of hours due to the overwhelming targeted attack. Again, this attack was possible due to the cameras being connected to the Internet, and apparently not having a suitable level of logical security to prevent remote access. These kinds of risks are not limited to CCTV cameras and are likely to increase in number as the “Internet of things” continues to evolve, where everything from refrigerators to watches to cars will be networked and accessible via the Internet.

Any network enabled device including cameras, regardless of the embedded security controls, will also remain vulnerable to

20

outside hacking if default factory passwords are not changed during the installation of these devices. This represents a further risk, which can be easily mitigated through good work practises and competent installation technicians.

CAMERA COMPONENTS Whilst the recent focus has been on a small number of manufactures only due to their country of origin, and due to the large portion of the market these brands make up, it should be noted that some other brands are either manufactured by the same company and re-branded or are made by the same factories.

There are many CCTV manufacturers around the world with some of the most famous brands being from Japan, Korea, Germany and Sweden. Whilst these companies are not involved in the current focus around potential CCTV camera risks, it should be noted that their products may not be manufactured in their homeland.

Even if a manufacturer does make their products in their own country, they may be made from components that are sourced elsewhere, which may open them up to potential risks, or at least put them in a similar category to the cameras currently under scrutiny.

NETWORK SECURITY Ideally, CCTV should be connected to a dedicated secure communications network. If CCTV cannot be connected to a dedicated network without Internet access, suitable network security controls must be implemented to ensure that cameras cannot be accessed by unauthorised individuals. If outsiders are able to hack into a CCTV system, there are a range of potential risks. These include, use of the cameras to assist in DDOS attacks, theft of security information, access to potentially sensitive recorded footage, the ability to change camera settings, switch cameras off or delete footage, or covertly using the cameras to case the facility, which may assist other subsequent criminal acts. It should be noted that the above risks will pose a different level of impact depending on the organisation weighing the risk. Appropriate measures should be taken to manage these risks to an acceptable level to the organisation.

CONCLUSION Selection of security measures should be based on clear objectives, minimising loss, cost/benefit, and a formal documented security risk management process. It is also beneficial for the individual/s determining security requirements to have experience in managing security risk, a good knowledge of security’s limitations and strengths, technical knowledge of security, and criminology theory.

Ideally, security solutions should: Deter would-be offenders, Detect offenders/incidents, Delay offenders for a period long enough to Communicate an alarm, and Respond to an incident to prevent it occurring or at least minimise loss in the event it has occurred. All of these roles should be accomplished swiftly and efficiently to provide effective security.

As new risks are identified it is important to maintain awareness of these and ensure they are considered in the risk management process. It is not a new concept for security technologies to be compromised or used against its owners by unauthorised individuals or criminals. The recent interest in potential risks regarding CCTV are another reminder of the type of issues that need to be considered during the risk management process, and if managed appropriately should not be cause for undue concern.

In order to maximise the potential benefits of CCTV, it is recommended that careful consideration be given on a caseby-case basis, so that specific objectives for CCTV can be clearly determined for each case, and consideration given to the likely success of CCTV to manage risk prior to implementation so that a cost/benefit analysis can be undertaken. In this respect it is critical that the intended purpose be clear, that the risk be assessed in terms of the known or anticipated threats, and that CCTV be considered in the context of holistic security measures tailored to address the identified threat and risk.

CLOUD COMPUTING

Facilitating excellence in the hospitality sector COLIN NICOL I DIRECTOR, DO DILIGENCE

With the world changing faster than ever before, we need to be more agile to achieve excellence in the Hospitality Sector. In the article below, we illustrate how Cloud software is currently being used to assist hotel operators meet and exceed the compliance standards required within the Hotel and hospitality sector.

C

loud based software is a catalyst that can be used to empower individuals to be more efficient and proactive and to drive transparency and accountability within an organisation.

Adopting cloud solutions has proven not only to free up your staff and contractors, but also provides visibility and access to data that would previously been cost prohibitive or simply not available. This allows for in-depth data and smarter analysis and provides the foundation for informed risk-based decision making.

Utilising smart Cloud Technologies not only allows for industry benchmarking but also actual industry experience and knowledge to inform operational and capital works planning.

customer experience, efficient use of resources and legal and organisational compliance.

While industry advancement blazes forward, many challenges clearly remain. The key universal challenge is still that TIME is a limiting factor for everyone and people are always pursing extra efficiency or timesaving measure that will allow staff and service partners more time to be more effective.

The world is evolving rapidly, and the expectation, is that people must achieve more with less. That expectation is not only selfimposed, but is placed on us by our managers, peers, industry, regulators and ‘best practice’. To achieve more with less, we need to work smarter rather than harder and cloud-based compliance software provides this opportunity.

Using experience and data from around the globe from our many hotel and other facilities experience, we share insights of what has facilitated excellence in hospitality facility management and some common challenges, as well different but successful approaches to everyday challenges.

THE PURSUIT OF IMPROVEMENT IS INHERENTLY HUMAN We strive for improvement in all things we do. The overwhelming benefits of this human need is evidenced everywhere in current industry. This is particularly apparent in the field of hospitality, where progress is improving

Figure 1: capturing and viewing data across multiple platforms is at the heart of cloudbased compliance.

Introducing cloud computing… not that it needs much introduction, as it has been with us for some time, and in the context of technology it is no longer new technology, but rather a facilitating technology which allows new technology, software and innovation to emerge.

Cloud technology has numerous benefits, particularly in the hospitality sector and we are now entering into an imbedded age where cloud computing is facilitating the delivery of operational activities, engineering and ancillary services.

To put this into context for the reader, think of the tasks that you do, or require to be done on a daily, weekly, monthly or annual basis. This could include, housekeeping – recording that housekeeping tasks are done, water hygiene and shower inspections (Legionella management), fire equipment and fire doors inspections, food hygiene management and all other management functions that go into maintaining a world-class hotel / hospitality facility.

With this, Cloud Computing allows all of these and more to be planned, executed and reported in a manner that allows for excellence, efficiency and transparency not experienced before.

Some of the Key Features of Cloud software Include:

and capabilities over recent years. The changes are clear for us to see in the direction that we are moving, from static computers sitting on a desk to the mobile phones or tablets.

The ability to take devices with us wherever we go, gives us access to information, software and work tools previously unprecedented. It is for us to take advantage of the available tools and make practical and efficient use of them.

There are many tools available to help organisations achieve compliance. Some specialised and some broad in scope. But with over 5.7 million apps available across five major platforms, there is likely an app available that can provide a solution for you. The question therefore, is what are you trying to achieve?

• Data in one location: the ability to view all data in context, without looking at separate spreadsheets, hardcopy folders and sampling results provides a powerful tool that gives you a view of the ‘whole picture’.

• Data as a predictor: when data is used well, it not only tells a story, but allows you to start predicting behaviours, be they people, infrastructure systems or seasonal impacts.

• Data as evidence: being able to demonstrate, at the click of a button that you have done what is required by the various standards and legislation is a precious commodity.

• Scale – we can scale up and down in moments. Allowing workflows and processes to be implemented, adjusted, improved and removed in moments. This allows not only compliance to internal and external organisational standards, but also to data to measure performance and drive improvements.

• Data scale – having access to useable information (data) is a key driver for measurement and improvement. Previously data was gathered by relatively small means, surveys, audits, samples etc. but with cloud computing, data gathering is taking place 24x7x365 and this provides more robust data and allows decision making on reliable and verifiable information.

• Flexibility – in today’s workplace, the only constant is change.

Providing systems that allow flexibility is essential. Cloud based systems facilitate rapid change and flexibility within operational systems. By logging on to a system while on your way to a meeting, you can facilitate the change requested on the same day. This change can be adopted across the local operation, across the county or around the world.

• Speed to deploy – cloud-based systems are peerless when it comes to speed of deployment. Setting up new users or completing new tasks in the field can be done in a matter of minutes (or less) and allow for actions to be scheduled and completed as quickly as needed.

In the context of compliance within the hospitality industry, there are multiple opportunities to work smarter to not only achieve compliance and best practice, but also to demonstrate this via a robust audit trail. And we all know how important that audit trail can be when things go wrong…

As we move into the mobile electronic age, the opportunity to embrace technology exists like never before. We are all aware of the massive developments in mobile device uses

24

Figure 2: Data should be used to highlight areas of focus and intervention

• Systems that are: o able to oversee the complex requirements of hospitality compliance, interpret them as simple tasks to be captured at known locations or assets. These tasks are simply relayed to the right persons who can then undertake the task in accordance with the schedule; o able to record results and track actions taken when results are out of specification. The audit trail is critical in demonstrating your due diligence and should be included in any electronic compliance tool; o able to report the data in a simple and consistent format that provide management with an overview of people and system performance; o easily amendable that can adapt to changes in legislation and ‘best practice’, so that when changes are needed, these can be easily and efficiently made and seamlessly introduced to staff;

o the spine of your compliance management, People will change throughout the lifetime of your facility. It is imperative that you have a system that can be easily used and adopted by new staff or contractors and that your system is ‘people proofed’ so that people are not able to change or disregard the system. This is particularly relevant in the hospitality industry with above average staff turnover and the diverse staff cultures and language frequently seen in the industry.

PRACTICAL APPLICATION With our experience and the access to the experience of our partners in supporting thousands of facilities, across hospitality, health care and education in the US, UK and Australia. With nearly 53 million individual results captured within our software, we have an insight into practical application of cloudbased systems.

Universally, we have found that people are looking for simple, efficient and transparent systems. While it may seem a juxtaposition to ask for simple innovative cloud-based solutions, the successful applications deployed in the hospitality sector have proven to be quick to adopt and simple to use. Simple to use means for persons from any level of the organisation to be able to pick up and be operational with minimal training.

Figure 3: Creating a range of compliance tasks, broken down into disciplines, allow hospital engineers to have a simple understanding of their compliance across a range of compliance fields.

Efficiency, transparency and control are at the heart of what cloud computing brings.

Performing tasks and measurements using mobile devices in real time removes the requirement for paper-based reporting and the well documented, and expensive challenges that come with paper records.

By using mobile devices, records are stored electronically, with a record of users, time and date and geo location, just a few of the inherent records able to be interrogated and produced as and when required. Add in photographs and built-in task performance parameters and you see the power of the software that people carry with them.

RELAX

By utilising cloud-based systems, hotels, and in particular facility managers have been able to schedule and demonstrate the level of activity required to maintain a compliant facility. From fire inspections, water compliance, food hygiene, emergency infrastructure and so much more, capturing all the scheduled tasks and all results, (favourable or otherwise) has provided engineers and contractors with much needed visibility of whether critical, but routine tasks are being completed.

Areas that successfully utilise cloud-based software include:

• Fire – with a significant number of physical tasks required to be completed weekly, monthly or at other intervals, fire compliance is a critical area where the devil is in the detail and this detail should be transparent. Fire contractors have traditionally relied on a single service report at the end of each visit, and clients have happily accepted this as their management mandate has been discharged. However, with

new services available, the level of detail and interrogation of reports is not only possible, but is critical to ensure the integrity of the essential services is maintained.

• Water – maintaining a healthy water system is critical in the in the hotel and hospitality facilities. Big data, continual operational management and strict controls around system performance are only a few of the key actions required to demonstrate that proactive risk management actions are in place and are diligently being undertaken. With hotels the world over providing many unwanted case studies of poor water hygiene, resulting in multiple fatalities, this is an area of critical compliance.

• Electrical – the lifeblood of any hotel, electricity is essential for every process in the hotel to function. Maintaining a compliant electrical infrastructure, while remaining compliant to national / international standards requires careful planning and diligent execution. With distribution boards, electrical equipment and infrastructure dispersed across large areas, maintaining the routine inspections and compliance across all the electrical infrastructure is essential. How is this done without electronic systems? How is management certain this is being done without spending hours checking, reviewing and then checking again…?

• Emergency equipment – essential equipment that is required to be well maintained and hopefully never used. Often the

only time this presents a problem is when the auditor finds that critical checks are not being carried out on critical infrastructure. However, that is the best-case scenario… what happens if this equipment fails the one time that is needed?

This is where cloud-based software takes the baton from traditional methods. By scheduling and recording all checks that are undertaken at the equipment, clients can be certain that all tasks are completed, all defects are closed out and the equipment will be in operational if it is needed.

And what about the less critical, but no less important tasks of housekeeping. Clients use software for housekeeping staff to record room cleaning and provide evidence to demonstrate that internal and industry standards are being met.

More advanced clients use the software for time-in-motion studies and analyse the important metric of speed vs quality. All of which is only possible with reliable and real-time data.

Achieving excellence consistently in hospitality is a challenge that all hotels face. The sheer volume of maintenance activities, compliance tasks and risk management tasks mean that being able to schedule, track, measure, manage and demonstrate compliance is an area that cloud based computing is ideally placed to do.

SLIPS, TRIPS AND FALLS:

Your duty of care

DAVE COLLINS I SENIOR CONSULTANT, QED ENVIRONMENTAL SERVICES

Hotels face particular challenges when it comes to the slip resistance of surfaces because many areas accessible by guests, visitors and staff have high pedestrian traffic, exposing flooring materials to greater wear.

H

otel owners and managers have a legal duty of care and legal compliance obligations with regard to the risk of pedestrians slipping, tripping, or falling on floor surfaces.

SLIP RESISTANCE STANDARDS FOR DIFFERENT AREAS OF A HOTEL It is important for hotel owners and managers to understand the minimum requirements for slip resistance in various areas of a hotel, according to the applicable Australian Standard.

For example, toilet facilities in hotels need a minimum P3 rating, whereas hotel rooms, bathrooms and en-suites, only need a P2 rating. The P rating of a surface indicates its resistance to slipping when wet – the higher the P rating the greater resistance.

In all commercial kitchens the highest anti-slip performance (P5) is required, as for all serving areas behind bars, though cold stores and freezers require a P4 rating.

The Australian Standard also covers external areas. Swimming pool ramps and stairs leading to water require a P5 rating whereas pool surrounds may have a P4 rating. External carparks require a P4 rating whilst the minimum for undercover carparks is P3.

A degree of judgement is required for some areas. A hotel lobby for example will often have polished or vitrified porcelain like surfaces for aesthetic reasons. This is relatively safe to walk on when dry but during wet weather it can become wet and unsafe. This possibility of moisture in the lobby may imply a minimum P2 or P3 requirement, whereas P1 is applicable if there’s certainty it is always dry.

MANAGING RISK OF SLIPS TRIPS AND FALLS Conducting slip resistance testing is important as it will help to reduce your exposure to: • injuries due to slips, trips, or falls • potential impact of litigation and liability claims • increased insurance premiums There are two major parts of slip resistance testing: • initial assessment of flooring material in the laboratory enables suppliers to certify slip resistance of a product prior to installation or delivery to site • ongoing monitoring of existing pedestrian surfaces by facility owners fulfils their duty of care and compliance obligations Ongoing monitoring is required because flooring surfaces wear from pedestrian traffic and cleaning regimes. Regular testing of pedestrian surfaces is the main element of an appropriate risk management plan.

Accredited and independent slip resistance testing will determine if floor areas meet minimum anti-slip performance requirements, and regular testing can help to manage risks arising from wear and surface treatments such as cleaning.

For existing floor surfaces hotel owners and managers will generally choose in-situ testing by a qualified professional using accredited and calibrated equipment by the: • wet pendulum test method, and/or • dry floor friction test method The wet pendulum test method provides customers with a slip resistance rating ranging from P0 to P5 with P5 being the

29

highest rating possible. The dry floor friction test method provides customers with a pass or fail classification depending on the measured coefficient of friction over the test run length.

This test is only valid for areas that are always considered ‘dry’.

• Test flooring surfaces for slip resistance at regular intervals because of wear from pedestrian traffic and cleaning

It is recommended that testing is conducted by an independent NATA-accredited service provider who is directly engaged by the hotel owner or manager. Testing should never be the responsibility of parties who have a natural interest in the compliance of areas they are responsible for (e.g., cleaning or refurbishment contractors).

ABOUT THE AUTHOR

For hotels, risk management planning can be quite elaborate when it comes to considering all surface areas where Duty of Care and Occupational Safety requirements come into play, so a tailored plan is recommended for each facility.

KEY RECOMMENDATIONS • Know your legal duty of care and compliance obligations • Understand the differing minimum standards for slip resistance of surfaces in various areas of a hotel, for example hotel rooms (P2), undercover car parks (P3) and commercial kitchens (P5) • When planning for refurbishment, specify that flooring materials are assessed through a NATA accredited laboratory prior to installation

30

• Directly engage a NATA accredited service provider who is independent of cleaning or building contractors

Dave Collins leads QED’s asbestos management and slip resistance testing practices. He is qualified through the British Occupational Hygiene Society and has extensive experience preparing and delivering risk management plans in the built environment. Dave and his team undertake slip resistance testing of pedestrian surfaces at QED’s laboratory and in the field.

HYDRAULIC SERVICES AND EDUCATION SECTOR LEAD (NSW & ACT) AT AECOM

here technology is concerned, the simplest ideas are often the best. When that Eureka moment arrives…. it can often happen when you least expect it, or does the actual location have anything to do with it? Whilst buildings are becoming significantly smarter, the design of the reliable bath, basin, shower and WC (albeit far more water efficient), have effectively remained timeless for a significant period. When we consider technology within plumbing, are we effectively overlooking the key ingredients that could effectively improve and maintain our health and well-being? So what exactly is in the pipeline, Paul Angus dives in head first, to flush out all the possibilities?

FLASH IN THE PAN Some of the best thoughts occur in the bathroom. Whether it’s whilst you’re singing in the shower, relaxing in the bath or sitting on the loo, we’ve all experienced that moment where a flash of inspiration strikes like lightning. History suggests this is no new phenomena; Archimedes is famed for terming the phrase,

32

Eureka whilst sitting in the bath! Does this sound like you, if you are a bathroom thinker, (not a stinker), what exactly are you doing when you have your best ideas?

Studies suggest that 40% of people come up with their best thoughts whilst spending time in the bathroom. It’s not surprising really, as the average person spends just over 20 minutes in the bathroom each day, or to put this in context that’s 450 days across the average lifetime. Whilst you’re reading this, (quite possibly whilst on the toilet with your smart phone), consider that only 12% taking part in the study do their best thinking at work. So there you have it, the key to increasing work based performance is all down to how awesome your toilets are!

THE INTERNET OF TECHNOLOGY TOILETS Buildings are becoming smarter, interconnecting with our smart phone apps. For example, allowing hotel guests to remotely communicate with their room heating or cooling, lighting and

opening and closing blinds, even room security can occur via cloud based technology. This undoubtedly assists in sustainable energy usage, sensor following movement patterns control lighting, however if we use the same sensors to become more intelligent to follow similar patterns to control water usage, this can also assist in heating the necessary amount of water required. What if we can operate the shower before even leaving the hotel bed to reach the desired temperature? A notification on their mobile phone can alerts them when the shower has reached their preferred temperature. They even have the ability to set a time limit on the showering period it to save water, too. The possibilities are endless.

and flushing at the touch of a button, or in some cases, with a simple wave of the hand from the throne.

FM Managers rely on the internet of technology to communicate with the buildings services plant to monitor performance and efficiency through the building management system (BMS). This allows this comparison if data to the already existing information stored in clouds to highlight any issues, identify when plant may not be operating, plus allow proactive replacement of plant.

So where is innovation and advancement in toilet technology leading? Our interest and fascination with science fiction often become reality. NASA relies and harnesses the ability of the humble toilet to monitor astronauts by sampling waste and report on their health and well-being. Although this sounds a bit gross, how beneficial could this be in the toilets back here on earth? Sensors are everywhere these days and part of our daily lives, but what if we take it one giant leap for mankind that bit further by embedding various sensors into the toilet to measure your vital signs and health and well-being parameters? Visualize your toilet, equipped with various sensors and microprocessors, logging urine information – and notifying you or your doctor if something going down the drain is different than the usual.

Japan is at the heart of endless technological possibilities, especially when it comes to innovation in the bathroom. It’s not just another trip to the loo, when you consider highly sophisticated toilets can provide users the luxury of a vast variety of functions, including heated seats, warm water jets,

Is luxury in the bathroom really cutting edge technology though? The bathroom of the future might also decide the age-old question of how much time women spend in front of the mirror, and with the use of smart sensors could even assist men with what spending five more minutes in the toilet actually means.

AIMING HIGHER, (RATHER) THAN THE TOILET SEAT

33

You would not need to provide urine samples at the hospital or doctor; your smart toilet would take care of that. The future of the humble WC is starting to become far more appealing, don’t you think?

The smart toilet of the future won’t be a stand-alone device, but part of an integrated network of information about you and billions of other people, in a system , of devices, servers, institutions and individuals that actively prioritises diagnosis, communication and prevention. Instead of flushing millions of terabytes, potentially gigabytes of useful data into the sewers each day, we’ll extract the essential information to provide a far healthier future.

Just think how remarkable your WC could be by saving lives, with the ability to notify their users when measurements aren’t quite right. The possibilities are endless, as the WC will also be able to send data to your smart phone, converting data that can provide suggestions on how to change lifestyle routines.

Taking it further, the technology will be able to alert medical professionals in case of emergency or to notify doctors if the patients do not get better even though they are adhering to the prescribed treatments. The everyday toilet could perhaps be propelled in becoming the perfect mechanism or monitoring and performing early diagnostics.

ONE, POO, PEE! Sound far-fetched? All the essential tools and technologies already exist today. Embedded sensors located within the WC can easily be connected to the buildings Wi-Fi network to transmit results to your tablet, smart phone or a health and fitness app, which could also relay certain data direct to your local doctor. How essential could this technology be? Let’s dive in.

Just think how effective advancements in technology can monitor and highlight key indicators on your health and wellbeing. The toilet of the future will monitor your blood sugars and cholesterol helping you to manage your health, how your body is reacting and when to take action. What if you are suffering from a bacterial Infection? Most of us don’t recognise when our body is telling us that there is an issue. Are you spending more time on the toilet than usual? What if you had instant access to the most up to date software that analyses your stool faeces and instantly reports to you via an app, that you have a bacterial infection or even a virus? The app can advise the appropriate treatment or if you should contact your doctor to seek further assistance…but hang on, being an app, it already has the ability to alert your doctor, in fact it has already notified your doctor, checked your calendar against the doctors and booked an appointment for you. If your toilet could do all that for you without you changing a single way you currently conduct yourself in your daily routine, it would be great, right?

How many pregnancies go undetected? What if the humble toilet could detect any hormone changes very early and advise you if you’re pregnant. No more messing around taking aim and also remove the agonising waiting game. Your app on your phone could even alert you and your partner.

34

Perhaps after a heavy night partying, you’ve woken to find yourself hugging the ever reliable porcelain throne? Of course, it must have been something you ate, right? Thankfully, the sensors embedded within your toilet have already detected the alcohol level in your system. The app on your phone has sent you a hangover cure recipe complete with a selection of fluids to restore your body to the state it requires. You cunningly already set up the app, so your doctor or employer isn’t notified of these events…of course!

A FLUSH FOR LIFE There are manual methods and self-diagnostic kits that can perform all of the above, but if we’re honest can often be messy, inconvenient and perhaps slightly non-hygienic. The everyday toilet in certain circumstances can monitor urine, picking up those key indicators of early diabetes or infection.

Certain kits from your pharmacist or doctor can of course alert you to issues with blood in your stool, a potential sign of colon cancer, just as quickly as you can flush the evidence away without realising, results are being sent to your mobile phone and recommending the appropriate course of action.

So why are toilets not already offering this service? Cost plays a big part, however misconceptions of self-diagnosing where something is not right with us, can be a potential mind field.

Are you lusting for a new toilet, or is the lack of data-share options of the bog standard toilet holding you back? What if the simplest solution to all our future was actually your humble WC, holding the key to your overall health and well-being.

It may sound far-fetched; however the internet of technology, and our toilets, is advancing so fast, that within a few years a global heath record data base will soon be available. Whether you like it or not, when you next check into a hotel, spending time in hospital or office building and use the facilities, your health information will be readily available, not only to you, local doctor or hospital, existing and potential employers, healthcare insurance firms, but even to potential online dating sites! So, the next time you’re experiencing that Eureka moment whilst spending some time in the bathroom, spare a thought for your toilet…..you never know, it very well could save your life in the future.

THE GROWING PROBLEM OF E-WASTE RECYCLING: Where to go for Australia’s hotel engineers?

WARREN OVERTON I CEO, ANZRP

Australia’s unquenchable thirst for new technology is matched to its rapidly growing volume of electronic waste (e-waste).

A

s information technology continues to permeate our lives, technological innovation is helping drive the creation of wearable devices, provide seamless networked environments, build smart homes, create virtual offices, and much more.

The result is simple - e-waste is one of the greatest environmental challenges of our time.

According to the Global e-waste Monitor, published by the United Nations University, current estimates suggest the world’s population is on track to generate 60 million tons of e-waste by 2021.

DOING THE RIGHT THING As pressure mounts on hotel engineers to provide effective solutions to reduce waste and maximise available reuse and recycling opportunities, they need to remain diligent in their efforts to ‘go green’ and to ‘live green.’

As a 21st century phenomenon, the ethical and responsible management of the vast array of end of life equipment that makes up e-waste is pivotal. By working in collaboration with third party organisations like ANZRP, you can easily map out an e-waste recycling strategy that is economically viable to your organisation and environmentally sustainable.

WHERE WILL ALL THIS PRODUCT GO? Like many nations, Australia is grappling with the challenge of preventing the unsafe disposal of e-waste, and increasing the volume of e-waste recovery and recycling.

36

Australia’s National Waste Policy was founded on the provision of a coherent and environmentally accountable approach towards waste management. A key pillar of this (and the reason ANZRP-TechCollect was established) is the Product Stewardship Act 2011. Seeking to mitigate the environmental impact of electrical products, the National Television and Computer Recycling Scheme (NTCRS) was launched.

In seven short years, more than 1,800 collection services have been made available and in excess of 230,000 tonnes of TV and computer e-waste has been collected and recycled.

This is more than the weight of Melbourne’s iconic Eureka Tower standing 91 floors above the city at an impressive 301 metres.

Over this time, 90% of materials recovered under the Scheme have been recycled.

As Australia’s only not-for-profit co-regulatory arrangement operating under the NTCRS, TechCollect’s approach is to ensure Australians have access to convenient, secure and responsible e-waste recycling.

Key to this is our recycling partner network operating to the highest standards with strict adherence to the standards of collection, storage, transport and treatment of collected e-waste.

Supported by our members whom represent some of the largest and most influential global IT and electronics manufacturers, ANZRP-TechCollect is well placed to capture end-of-life electronics. In six years, our dedicated channel has recycled over 130,000 tonnes of e-waste.

A PROBLEM REQUIRING MULTIPLE SOLUTIONS – MANAGING YOUR E-WASTE RESPONSIBILITY Any hotel engineer would agree that no ‘silver-bullet’ exists to help you achieve a smart, sustainable and efficient approach involving the recycling of e-waste.

Develop an e-waste strategy – Help avoid the unwanted build-up of stock by identifying the problem (possibly through an e-waste audit) and putting forward a workable plan to address your site’s requirements. By identifying the potential waste stream you can make sure you are prepared to manage it appropriately.

ANZRP recommends a great place to start is with Standards Australia’s recently released guidelines entitled Aggregation of discarded electrical and electronic equipment (e-waste) for collection.

Select reputable recycling partners – Protect your brand.

Always ensure strict standards for downstream vendor processing and materials traceability are adhered. This should include, at a minimum, compliance to the Australian standard for e-waste recycling (AS/NZS 5377:2013) as well as HSE legislation.

These guidelines will provide you with best practice principles for assisting hotel engineers design and implement sound aggregation and storage programs for discarded electrical and electronic equipment. Those wishing to find out more, should go to https://infostore.saiglobal.com/.

Clearly define the scope – To gain the benefits of a well delivered program, it is recommended users are familiar with inclusions and limitations, of the service. Clear communication and appropriate collections systems are vital.

Here are some suggestions you might consider: Make life easy – Focus on implementing a solution that makes it easy for people to embrace responsible recycling. Adopting the KISS principle, ensure processes are simple to follow, receptacles are easily identifiable, and communication is kept clear and concise. Remember the fewer hurdles you place, the greater the chances of success.

‘Clean the decks’ – Work with key stakeholders to create targeted campaigns helping collect and recycle e-waste. One such example is the implementation of a ‘Clean the decks’ initiative - a one-off collection drive to drive the responsible handling of e-waste and whilst educating hotel staff.

Call TechCollect – ANZRP-TechCollect is happy to provide assistance in the creation of effective communications campaigns to support better e-waste recycling services. We

can do now to recover valuable commodities from end-of-life equipment and return it to our manufacturing industry.

WHAT ABOUT THE DATA?

MORE INFORMATION

It’s understandable to be concerned about risk surrounding data security. Research undertaken by ANZRP-TechCollect has revealed that personal data is a key concern amongst Australians, with 64 per cent stating they don’t recycle e-waste over fears information contained on the hard drives of their electrical devices may fall into the wrong hands.

More and more resources are now being made available for facility managers to manage e-waste. You can visit the TechCollect web page (www.techcollect.com.au) for information on recycling standards, collection systems and management of data.

Deleting files from a computer’s disk drive or reformatting does not “physically” overwrite data. Options available include ‘wiping’ data with specifically designed software packages, or utilising an external data destruction service, deploying a combination of software and physical data destruction processes. A comprehensive guide about data deletion/destruction can be found at techcollect.com.au/ delete-your-data/.

YOU CAN TAKE STEPS TOWARDS A CIRCULAR ECONOMY You have probably heard a lot of late about the ‘circular economy’ and the importance of moving away from our current linear ‘take-make and dispose’ approach. Responsible management of e-waste is an excellent example of what we

Caring for your silent assets:

OPERABLE WALL MAINTENANCE PROSPACE INNOVATIONS PTY LTD

Operable Walls offer your hotel function space the flexibility to change, whether it is opening up to accommodate a large function or dividing it into smaller gatherings. They allow you to use the space efficiently and cater to your client’s needs.

W

ith all its benefits, use of operable walls must be done with precaution and safety in mind. Operable walls consist of heavy panels suspended on trolleys from a track. There are numerous moving parts within the walls that need to be cleaned, aligned, tightened and lubricated.

Regular use can result in wear and damage to the moving parts and can also reduce the acoustic performance. In order to keep your operable walls at peak performance and optimal condition, it is essential to observe a regular service schedule.

SAFETY

• Loose Jamb posts?

• Sticky hinges?

• Excessive wear on tracks?

• Noisy when opening and closing panels?

HOW OFTEN SHOULD YOUR WALL BE SERVICED? Below is based on manufacturers based on the frequency of use of the wall.

Workplace safety is paramount to your hotel and you want to ensure the safety not only for your employees, but also clients and guest who utilise these spaces.

Panels are heavy and bulky but with proper use and regular maintenance they can be moved very easily with little effort.

Workplaces have a legal obligation, so far as reasonably practicable, to eliminate or minimise hazards and risks and maintain the workplace and facilities in a safe condition and provide appropriate training.

Only staff trained in the correct operation of operable walls should operate them to minimise risks and non-essential repairs and maintenance.

DOES YOUR PARTITION NEED A SERVICE? • Panels not gliding effortlessly?

• Panels need re-levelling?

• Doors not locking or closing properly?

• Noticeable increase in sound between rooms?

• Top and bottom seals both operational?

40

LIFESPAN Whether you have a manual operated wall, a semi-automatic system or a fully automatic wall they all have a capital value associated with them that needs to be protected.

As with any product, operable walls have a lifespan, which can be dramatically extended with routine service and timely repairs. An unattended wall is likely to develop problems resulting in the need for a significant and costly overhaul or possibly even a complete replacement.

If serviced on time and looked after correctly, an operable wall will continue to give you trouble free performance for many years.

CHOOSING A SERVICE PROVIDER So what should you look for when considering a service and maintenance provider for your operable wall?

Firstly, you should be aware that you are not obliged to go with the aftercare service offered by the manufacturer or installer, and you should shop around and compare quotes. However, you need to ensure that the company you choose does have the capability to maintain your particular wall. Ideally, a professional aftercare service should have in-house trained technicians that offer a full service rather than a ‘due diligence’ visual inspection.

A comprehensive examination should include checking all seals are intact and fully operational, cleaning and lubricating the track and fixings, alignment of panels and tracking system as well as a full check of the motor and key switches, panel contacts and push buttons.

A non-movable operable wall may lead to disrupted events and cancelled bookings. In this case an emergency call-out arrangement is essential. By entering into a service program, the regular maintenance will significantly reduce the chance of a problem arising in the first place, but if something does go wrong then you have the reassurance of prompt and efficient back-up.

BRINGING HOTELS TO LIFE PETER SKEEN I PRINCIPAL ELECTRICAL ENGINEER, AECOM

1. INTRODUCTION

M

odern hotels are required to be an integrated seamless experience presented to hotel patrons and staff alike. Guests expectations of the technology within the hotel are increasing rapidly and the outcome of the hotels control, connectivity, amenity and safety will largely be dependent upon the quality of the Electrical services design of the development.

When it comes to designing modern hotels, Electrical and Information & Communications Technology (ICT) engineers must be at the forefront of technological advances. The lighting design plays a vital role in creating ambiance within the space, communications systems are now connected 24/7 and adopting a digital infrastructure approach with a greater emphasis on collaboration between users and building technology.

Successful hotel developments operate seamlessly and the electrical services system enables the connection between building user and the space. Lighting, access control, communications, audio visual and entertainment systems are all part of the electrical / ICT services design that requires careful co-ordination with building users and other disciplines to achieve a user friendly technology enabled environment.

This article will explore some of the key elements of Electrical Building services design within hotel developments including the latest technologies, as well as touching on the significance of Electrical Building Services design and how it can make or break when designing a quality hotel.

2. KEY ELEMENTS 2.1.1 Lighting Design One of the most critical elements of building services design is lighting design and is an essential part of creating an environment that can have a profound and direct link to human experience, mood, health and sense of well-being. Lighting designers require to take into account the functionality of the space, the desired perception of the environment, safety aspects and the biological effects the lighting will have on the occupants. This level of detail is often not at the forefront of the client’s priorities as they are focused on functional floor plans and operational decisions.

Another important element to consider is the effect the lighting system will have on the productivity of staff. A lighting design utilising quality products and designed well will enhance performance in the workplace and assist in preventing fatigue.

Lighting designers should advocate for a collaborative approach with all disciplines and client stakeholders to ensure the desired outcome is realised.

Based on the concept that lighting has a dramatic effect on building amenity, there are certain techniques that can dramatically enhance the overall appeal of the lighting design and therefore the space.

Firstly, selecting good quality LED lighting is essential as lumen depreciation and colour consistency can become a major issue if poor quality fittings are selected. The following example of criteria should be considered to ensure the lighting selections will perform over time.

49

• The luminaires should first and foremost comply with Australia standards,

2.1.2 Information & Communications Technology (ICT)

• All luminaires selected should have photometric testing data available from a certified testing laboratory.

Another key element that plays an important role in the operation of the building is the ICT system. The data and communications infrastructure act like veins within the structure literally bringing the hotels systems to life. Providing a building that incorporates centralised networked systems enables facility managers to review the health of the building services from a central location across the network. Some examples of electrical and communications systems that have the ability to be connected to a local building network include:

• The colour temperature of the fittings should greater than Ra80.

• Centralised emergency lighting monitored system

• McAdams step ellipse tolerance ideally of 2 or lower.

• Entertainment systems

• The luminaire lumen depreciation should be nominated and 50,000hrs as a minimum.

• Security and CCTV

- AS/NZS 60598.1, Luminaires General Part 1: General requirements and tests.

- AS/NZS CISPR 15, Limits and methods of measurement of radio disturbance characteristics of electrical lighting.

- AS/NZS 61347.1, Control gear.

Providing illuminance on the ceiling and walls in addition to the floor adds significantly to the amenity of the space. Bright surfaces on the ceilings and walls creates a pleasant and stimulating environment. Another important point to consider is the colour rendering index of the fittings. Colour rendering is the ability of the light source to reproduce true colours and luminaires with a high colour rendering index will ensure the space portrays colour and textures that appears vibrant and stands out.

• Audio Visual and Public address • Digital signage • Lighting control

In principle, the lighting should integrate with the fittings and fixture theme of the hotels architectural character and electrical / lighting engineers are encouraged to collaborate and integrate the lighting options early in the design stage to establish the desired lighting strategy.

Selecting a user friendly intelligent lighting control system to complement the lighting design will ensure maximum flexibility to control, dim, automate and interface to other systems. By adopting the above principles the lighting design will make an inviting space that will attract people to the hotel and ensure they will have a more pleasant experience.

50

Wireless sensors are becoming a valuable asset to monitor temperature, lighting, noise and occupancy. Data is transferred to the central control system and analysed to optimise the building systems to suit present needs. An example with electrical and communications equipment is switchboard busbars and communications racks. Wireless sensors can monitor switchboard busbar temperature and communications

51

rack headloads to provide an alarm should these exceed safe limits. Switchgear has also adopted wireless switches as an option with remote control of circuit breakers now possible with these devices.

3. NEW TECHNOLOGIES 3.1.1 Digital Infrastructure The advancement within the digital infrastructure space within Building Electrical & ICT services engineering is changing at a rapid pace. Electrical & ICT engineers should look to adopt systems that can enhance the user experience within the building and investigate options to provide a connected and convenient environment. Some examples of modern digital infrastructure are outlined as follows: Technology Enabled Hotels A large proportion of spaces within new hotels are adopting a technology enabled approach. Some examples of modern technology within hotels include.

Guest applications • New hotels are offering a guest application providing useful information on hotel services, event information and notifications. In addition, remote check in services and room service are becoming a popular feature via mobile apps.

Mobile Phone Room Access • The mobile phone is beginning to replace the plastic card for entrance to guest rooms. This idea provides the user with personalised experience without having to carrying an additional card to access their space.

Digital Hubs • Having the ability to connect to an in room digital hub provides guests with connectivity to the TV, sound system, lighting and blinds.

Digital AV and communications design of the above systems become more complicated with these types of services as connectivity for a much greater quantity of devices is required than ever before.

52

Internet of Things (IoT) Electrical & ICT engineers will more frequently require to incorporate designs utilising the Internet of Things.

Smart buildings are an example of the IoT where the smart infrastructure within the building has the ability to analyse the environment to make real time adjustments to lighting, temperature, access control and energy consumption.

As building services engineers, we need to ensure each design discipline comes together and has a unified approach to ensure each sub-system has connectivity to a common building network platform.

An open architecture system is important as our customers require full flexibility into the future when maintaining these systems. If this type of system is not adopted, compatibility issues can arise between different equipment vendors.

Digital Application Software Digital apps have become a powerful tool for smart buildings and precincts to relay important information to occupants.

Some examples of the information that can be broadcasted to individual smart phones via a personalised application include safety messages, location maps and sales information.

This is another example of how the electrical and ICT system can bring the building to life making it more convenient and efficient for occupants and also maintenance staff.

The communications systems described above can be overwhelming for clients due to the complexity of technology options, constraints and technical standards. Electrical & ICT engineers require to engage with the technical stakeholders of the business to ensure the technology will be fit for purpose now and into the future to meet the data and technology goals of the business.

4. LOOKING AHEAD Electrical and ICT Building Services Engineering is constantly changing with new technology making our hotels, workplaces, businesses, public buildings and places appealing, connected and convenient environments.

As we move forward more devices will inevitably be connected via the internet of things (IoT) making our lives even easier by having more data available and technology that adapts to the occupants of the building will become more pertinent.

5. SUMMARY To enable a dynamic, collaborative and inviting environment the electrical and ICT services design will have a dramatic effect on the usability and appearance of today’s hotels. As Electrical and ICT engineers embrace and adopt a fresh approach by utilising energy efficient products, the latest digital technology and

integrated systems this will ensure feedback from building users is a positive one!

This article touches on a small sample only of some key elements and new technologies when designing Electrical and ICT systems within buildings and represents a small fraction of the overall considerations when designing a full working system. Other considerations not covered typically include dry fire detection, lightning protection, security/CCTV, Television distribution, power distribution and many more.

Practical aspects of non destructive corrosion monitoring in the HVAC industry or

HOW TO MEASURE WHAT YOU CAN’T SEE! ALLWATER TECHNOLOGIES – NON DESTRUCTIVE CORROSION MANAGEMENT SOLUTIONS

THE STATUE OF LIBERTY – A HIGH MAINTENANCE LADY! There are intriguing connections between the Statue of Liberty, the Eiffel Tower, HVAC condenser water chillers....and frogs legs! Gustave Eiffel, in addition to designing the tower that bears his name, also provided the engineering design for the Statue of Liberty which came close to falling over before its 100th birthday! Unlike the Eiffel tower, which was constructed entirely with iron and steel, the Statue of Liberty boasted 123 tonnes of internal iron structure supporting 72 tonnes of external copper sheeting (and 12,600 rivets). The analogy is a steel tubesheet in a heat exchanger or chiller supporting copper or Gustave Eiffel & his brass tubes and the tower problem is principally dissimilar metals in direct contact with each other, otherwise known as Galvanic Corrosion. The statue was delivered in 1884 and in 1981 the French-American Committee for the Restoration of the Statue spent $US230 million replacing beam by beam structures, only this time with provisions to effectively separate the steel from the copper!

Enter the conversation Mr Luigi Galvani, an Italian gentleman famous as a Physician of Bioelectricity – the study of electricity in animals! He is credited with discovering that an electrical current will create a spasm in frog’s legs (the world’s first volt meter) and that such spasms occurred when two dissimilar metals are in contact with each other, causing rapid pitting type corrosion in the least Luigi Galvani & his frogs legs (below) noble metal. Luigi’s name describes “galvanic corrosion”, the “Galvanic Series of Metals”, and the process of “Galvanizing”.

CORROSION CHARACTERISTICS OF COOLING TOWER CONDENSER WATER SYSTEMS HVAC chillers, because of their metallurgy and function have to survive eight simultaneous threats: 1. Electromagnetic Instability – The Longest War Syndrome All metals occur naturally in the ground as the oxide simply because their electromagnetic potential (EMP) is stable, and at low activity. Once mined and processed in a blast furnace and shaped into commercially required structures and items, the pure metal is unstable and its EMP is much higher than the oxide. The natural driving force is to lower the EMF and so a “war” begins. Rusting (corrosion) cannot be stopped but can be retarded to achieve acceptable equipment longevity.

2. Water saturated with oxygen Oxygen is involved in all corrosion mechanisms – remove oxygen and the corrosion process literally stops. However, a cooling tower uses ambient air to cool the system water and so the water flowing through the chiller is saturated with oxygen.

3. Mixed metallurgy – galvanic series of metals Copper, steel (mild) and stainless steel are the most common base metals found in air conditioning equipment and any combination will trigger galvanic corrosion with the least noble metal corroding rapidly. The Galvanic Series of Metals quantifies the corrosion potential of each known metal and the greater the electromagnetic potential difference between any two metals the more rapid the corrosion.

4. Temperature effect [∆T°C] Corrosion rates double for every 8O°C increase in temperature and cooling towers, in general, operate with a temperature difference of 6O°C. This means that the corrosivity of the water due to temperature alone is 2 x [6/8] = 1.5 times greater for the “hot” water exiting the chiller compared to the “cold” water entering the chiller.

5. Microbiologically Induced Corrosion [MIC] MIC is the term used for the phenomenon in which corrosion is initiated and/or accelerated by the activities of micro-organisms and infers that MIC is an electrochemical process and that micro-organisms are capable of affecting the extent, severity, and course of corrosion.

56

6. Effective air scrubber – suspended solids [erosion] and biological food sources Cooling towers are designed to efficiently use free ambient air to cool water. To be effective and efficient the volume of air required is considerable which means that anything in the air within the capture zone of the cooling tower will be sucked into the tower, and “scrubbed”.

7. System Water Corrosivity

Industrial standards, such as the Langellier Index and the Ryzer Index can be used to predict the corrosivity or scale forming tendencies of water supplies used for heating and cooling.

In cooling tower systems, the water chemistry is adjusted with selected chemicals to achieve an acceptable balance of corrosion and biological control. The process is an exact science and deviations from target control chemical residuals can have major negative effects.

8. Linear Velocity [erosion/under-deposit corrosion etc] Copper, it is true, is more noble than steel in resisting corrosion in water cooled systems. However, copper and its alloys have “softer” surfaces and are more prone to erosion than steel.

Metal wastage can occur due to hydraulic influences.

CORROSION MONITORING WITH COUPONS The metallurgy, design, manufacture, exposure, retrieval, cleaning and analysis of corrosion coupons is governed primarily

by ASTM D2688-D15 which is the internationally accepted code by most of the western world.

AN INTERNATIONAL HOTEL IS NOT YOUR

AVERAGE BUILDING

NEIL WEENINK

Your average building is very quiet after business hours, and even quieter in the weekends. The cycle of activity is predictable and unvarying, and contracted rectification work may be planned with comparative ease.

T

he converse of this scenario is the international hotel where business never stops, whose character rarely conforms, whose design stratagem is always a monumental gamble, and for which there most certainly should be more published data. Because in truth, the international hotel is not your average building!

1.0 INTRODUCTION To extrapolate from Murphy, a hotel is a place where it generally will happen, usually does, and at three in the morning. There is something awesome about the perceived rights of a paying guest after the dry cleaning plant in the hotel mysteriously deposits a red hue over the white silk blouse.

Or the new bathing suit changes colour in the chlorinated swimming pool. Or the Fire Brigade was rude just because they, the paying guests, were having fun with a cigar and that sprinkler thing in the ceiling, and all hell broke loose.

This is a sometimes serious and sometimes whimsical look at why an international hotel is not your average building. The paper will trace something of the birth and the operational life of these challenging buildings.

The demands on services in a large hotel are unique in the Building and Services industry. Within any 24-hours there may be several entirely different activities in progress, each calling for separate services needs, and these may all change again in the following 24-hours. Buses embarking or disembarking hundreds of guests at any time in the 24-hours, trigger off electrical and hydraulic demand cycles not to be compared with the average office building, and which stretch the ingenuity of systems controllers, both automatic and human. A hotel is the sum of constantly flexing systems. Of large demands on energy sources through varied time frequencies; in short, a mix of both theatre and laboratory.

2.0 HISTORY The consideration of hotel services, as we understand the meaning, would have begun in the early 19th century, when there may have been running water and heating in certain hotel

guest rooms. At that time the manager certainly managed, repaired, fed the coal-fired boiler, and kept the lamps burning.

He was all things to all people. In the 1820’s indoor toilets appeared and coincidentally locked guest room doors, the 30’s saw the first baggage elevator and gas light, the 40’s private baths, the 50’s passenger elevators by Mr Otis, and in the 1870’s the first ever fire proof structure. In the 80’s came electric lighting, the first concrete structure, and the first mechanised hotel laundry. And in the 1890’s, telephones were provided in all guest rooms for the first time. The beginnings of the new age, if you will, were in the early 1900’s when E. Statler marketed “A room and a bath for a buck and a half.” The individual bathroom had arrived, with radios following in 1926 and Statler installing one of the first guest room air conditioning systems in 1934. I suppose the famous Minneapolis Honeywell Chronotherm Thermostat with a wind up clock automatically controlling the coal furnace draft dampers of households in those days, would have been adapted to the new-fangled air conditioning systems.

Over the following 60-years, many additional services and systems have been added, but sadly there have been few changes to what hoteliers refer to as the ‘back of house,’ that honeycomb like area into which plant is squeezed and where service staff operate systems and repair equipment. There is to this day an attitudinal time warp, if you like, between engineering staff of a large hotel and the other staff. There are many historical reasons for this, but there is also the very real mysticism of ‘things technical’ to lay staff members.

The international hotel is operating 24-hours each and every day; it is an immense machine. A celebration of Mozart, the launch of a new car model, a marriage, a separation; the hotel never shuts down. Not for wars, pestilence nor plagues. Some of the grandest imagineering have been performed in hotels during total breakdown of power sources, or during a typhoon, or when somebody left a spanner in the chiller crankcase. The show has always gone on. And all the while the services are cajoled into just a little more ......

61

3.0 DEVELOPMENT Recently I was involved with a major project in South East Asia which among other things, planned 9-international hotels, each of around 450 rooms and each of a different concept. I attended technical design team meetings each month, and I am still saddened and frustrated at the great lack of hotel related data to emerge from those meetings. To emerge and to be used in functional design. But it turns out there is extremely little hotel related data, and my frustration was in not being able to get the information I needed.

Examples: Maintenance and utilities costs / usage / per air.con / non air.con sq.metre / per occupied room / per person / per food cover / per laundry piece / so on.

Hot water storage, temperature and flow characteristics at peak draw were widely discussed at my insistence, due to the combined experience of many hotel Chief Engineers in Queensland who suffered either empty or cold [or both] hot water systems when bus loads of tourists from many different countries began arriving en masse from around 1988.

An international hotel is not your average building because of the many situations the systems must be sufficiently flexible to accommodate. Examples: Switching to a cheaper toilet paper can have disastrous effects on the sewerage system.

These same devices being used, hundreds of them almost simultaneously by a large group of harassed arrivals. Likewise cold or hot water - particularly hot water. Air handling and fan coil units operating far out of specification to serve special hotel needs; chocolate making, butter sculpture, drying rooms, television lighting, guests arriving from a northern winter or a southern summer or tropical humidity, all demanding the different conditions. Then the Peak, the ultimate electrical kilowatt demand when the ballroom has just filled, the kitchens are at maximum output, the hot water and chiller systems just settling down, and those darned buses arrive again. At what cost, this maximum demand on the electrical authority?

There was a time when money and labour were cheaper, and hotels were impressive monuments to their owners, designed to withstand use and abuse for years. Perhaps they were inefficient monuments - but this was of no real concern; the fact is that the entity had a life expectancy unheard of today.

For today the hotel is no longer the only jewel in the crown, rather it is one of several jewels in the portfolio, and it had better show a satisfactory return to investors. The time span from conception to commissioning is shrinking every year, not only due new construction techniques but also because of the necessity to generate revenue as forecasted - even if that means a room with no bed, but a darn good rate! And of course this means a fast track technique guaranteed to turn the hair grey of any incoming Chief Engineer, for it is a safe bet that he will have a ‘punch list’ of defects some metres long on his first tour of the site.

Many years ago, I began a list of the more repetitive of these defects, using notes of earlier years abroad, and the experiences of colleagues in the hotel industry, and thus was formed the

62

LORB list, as it is now affectionately known. The development of Lorb is interesting, as for example - ‘his work was somewhat lorbatious’, or ‘there is lorbatuity due the client’. The concern is over the repetitiveness of these defects, examples; • The difficulty, often impossibility of major equipment overhauls due to restricted plant room space.

• The need to run expensive chiller plant continuously for the few 24-hour operations in hotels, when small split units would do.

• The exposure of condenser piping to cooling tower chemically laden ‘rain’.

• Services hidden or buried, or even poured in with the cement.

• The AHU filters that cannot be reached, and the motors that cannot be serviced. and so on...

These deficiencies may be broken up into those relating to project cost squeezing or poor design, poor supervision or a lack of understanding of hotel operations. And it is this last statement which is, in my view, very significant. The understanding of subjective criteria as it relates to hotel operations, it is here where ‘differences of opinion’ may result between the owner, the architect and the engineer who will ultimately operate the property. Criteria, for example concerning maintainability, reliability, flexibility, etc..

An international hotel is not your average building because it has a permanent executive team to manage and operate it, and some of this team are always on duty. [This is comforting to know at three in the morning, when one of the guest lifts fails with you inside making a discreet exit.] The efficiency and the security of their responsibilities depends very much on the design and fit-out of the space, and of the equipment and fixtures they work with. And this of course, is the challenge to the architect ‘and all who sail with him’. Some years ago I asked each departmental head in an hotel for ideas on placement of their department in relation to the ‘back of house’, and hotel operations as an entity. This produced novel concepts, entirely practical to those who operate an hotel, but entirely odd to those whose layouts have been presented and accepted by developers for the past 40-years.

4.0 CONCLUSION In the hotel business, we call the opportunity to gain experience in another department, ‘cross exposure.’ It works well for potential managers. And I believe the scheme would be of immense benefit to architects and M & E people to have some exposure in all hotel operations. I would also recommend that eg. BOMA should consider compiling a broader data base of historical technical material from larger hotels. The Australian Institute of Hotel Engineering would be pleased I know to give full support. All this could be a big step towards an integrated development team, and with enthusiastic input from the client, an international hotel worthy of this next century.

WATER HYGIENE in pools and spas WATERLILLY AUSTRALIA PTY LTD

M

odern water treatment is a basic requirement for healthy pools and spas. Of course, the treatment results should be checked regularly in order to determine whether the water treatment is optimal, especially in consideration of changing operating conditions such as the number of bathers, the weather, the type of disinfection, etc.

If there are deviations from the recommended values for the hygiene parameters, measures can be taken to eliminate a potential health risk ahead of time. A brief explanation into the significance of the most important verification methods is presented below:

FREE CHLORINE Free chlorine is an effective means of disinfection and oxidation of water in swimming pools and spas. How often and how much chlorine must be added depends on how frequently the pool is used. Other factors, such as the water temperature, solar radiation and addition of fresh water, must also be taken into consideration. The free chlorine formed in the water guarantees disinfection for a limited period and is nearly odourless. The recommended measurement range is between 0.3 and 2.0 mg/l, depending on whether inorganic or organic chlorine (stabilised chlorine) is used. The measurement of free chlorine in parallel to the pH value is normally carried out with a photometer instrument.

COMBINED CHLORINE With the chemical reaction of free chlorine with organic impurities, chlorine compounds like combined chlorine or chloramine arise. These chloramines cause skin and eye irritation and the unpleasant chlorine odourâ&#x20AC;&#x2DC;. Combined chlorine has practically no effect as a disinfectant. In order to kill off micro-organisms or render them harmless and to break down combined chlorine, the pool water must be re-chlorinated regularly. The concentration of combined chlorine should be minimised (<0.2 mg/l); ideally there should be no trace of it.

TOTAL CHLORINE Total chlorine is the sum of free and combined chlorine.

First the free chlorine is determined, then the total chlorine.

The difference from the two values is the concentration of combined chlorine.

64

PH VALUE The pH value indicates whether the pool water is acidic or alkaline and is a crucial factor for the efficacy of the free chlorine as a disinfectant. If the pH value is less than 6.5 (acidic range), eye irritation occurs. Signs of corrosion can also appear on metal parts. As pH values increase above 7.8 (alkaline range), the effectiveness of free chlorine decreases. The water can become clouded and calcium deposits can form. An ideal pH range is between 7.0 and 7.4.

ALKALINITY Alkalinity is the term for the acid buffering capacity of the pool water. It is part of total hardness and is also identified as temporary hardness. High alkalinity values prevent heavy fluctuations in the pH value. With a high alkalinity, the pH value is difficult to influence. With a low alkalinity, very small additions of acids or bases can trigger heavy pH value fluctuations. Therefore, the alkalinity affects the stability of the pH value and the pH value, in turn, determines the effect of the free chlorine as a disinfectant. The alkalinity should be adjusted to a range from 100 - 160 ppm (mg/l) of calcium carbonate (CaCO3).

OXIDATION AND REDUCTION POTENTIAL (ORP) Oxidation-reduction potential (ORP, redox) measures the rate of oxidative disinfection caused by the addition of the effects of all oxidants in the pool water. The unit of measurement of ORP is millivolts (mV). The ORP is the potential of a disinfectant to do its work of inactivating micro-organisms and oxidising organic materials. The higher the millivolt reading, the more powerfully the swimming pool water is able to oxidise and disinfect. ORP is an indicator of micro-organism inactivation and swimming pools, an ORP of 700 to 720 mV allows for both a quick disinfection and for breakpoint chlorination (destruction of chloramines) where conditions permit. ORP should be checked against manual free and total chlorine measurement daily and the probes and other equipment must be regularly maintained in accordance with the manufacturer's specification.

TOTAL DISSOLVED SOLIDS (TDS) TDS or Total Dissolved Solids is the measure of the total of all the soluble substances dissolved in the water. It is usually measured by assessing the electrical conductivity of the pool water. For regular fresh water swimming pools, the maximum

POOL FEATURE

recommended TDS level is 1,500 ppm. Values above this can lead to problems such as cloudy pool water, staining of the pool surfaces, scaling, hard water and a salty taste. TDS values of up to 4,000 ppm and more have been noted in some well-balanced pool water so the individual levels of total alkalinity, hardness, conditioner, pH and metals should be considered along with the general state of the pool and its chemical demand. The TDS value should be used as an indicator of the volume of soluble particles in the pool relative to that of the fill water used.

WATER TESTING â&#x20AC;&#x201C; SELECTING THE RIGHT INSTRUMENT Those who run a professional swimming pool or spa know how important good and accurate testing of the water is.

Good measurement and control of the quality of the water are essential not only to the waterâ&#x20AC;&#x2122;s appearance. More importantly it plays an essential role in the consideration of bather comfort and safety. Regular and careful analysis also helps in the control of chemicals, keeping costs down, and the protection of the plant / pool and its equipment.

There are several options out there for water analysis equipment. First and foremost, none of the options is wrong.

However, some are more appropriate to specific application.

Therefore, before selecting which system to use and before embarking on the testing itself, it is important to consider the options available and select the method most suited to your needs.

POOL FEATURE

At very least, the following considerations should be taken into account: • The tests you need to carry out – which parameters are you looking to measure? At the lowest level, Chlorine (or Bromine for Spas), pH values and Alkalinity are typical.

• The accuracy required to meet operating procedures. This is of particular importance for pools / spas utilized by the public.

• Do the results need to be recorded for potential audits? This is of particular importance for pools / spas utilized by the public.

• Where the tests will be carried out?

• Who will be doing the testing?

Once a response to these questions has been found, you will probably be faced with one of the two following alternatives: a visual comparator or an electronic photometer based system. Each method has its own respective advantages and disadvantages.

PHOTOMETERS Photometers are electronic instruments designed to measure parameters via the colorimetric principle. The units give a direct, accurate digital reading of the test being carried out – clearly displayed on the screen. This removes any potential subjectivity being imposed on the reading. They are easy to use and can be operated in any lighting conditions. Most photometers can also be battery operated so still appropriate for in situ use.

Results to be transferred to either a printer or, alternatively, to a PC where they can be stored for review or historic reporting.

This is beneficial to any facility where water quality might be subjected to audits.

Being electronic, however, does mean the instruments do need to be well maintained, kept clean and regularly calibrated. Check Standards are now available to help verify the instrument’s calibration.

COMPARATORS Comparators are visual instruments that use a series of discs with continuous colour scales to take a measurement. These

66

easy-to-use colour match systems are economical, consistent and enable reliable testing. Typically, the systems are colourstable, made of non-fade glass and ensure consistent results over many years without the need for recalibration. However there are some disadvantages. The readings are, by their nature, subjective and can be affected by a number of external influences. Comparators should be used in natural daylight so additional lighting systems may be needed. They rely on an individual’s ability for colour matching. Finally, although readings can be recorded, they must be noted by hand. There is no ability to print or store the results electronically.

Most importantly, if you operate a public pool you need to test with instruments that adhere to local council or health department guidelines. Often the minimum requirement is a Photometer instrument.

COMPLETE WATER ANALYSIS Lovibond Photometer systems operate using a photometric measuring principle with tablets reagents having long-term stability. If all of the values are within the correct range, impeccable water quality is assured along with the long-term preservation of the structural materials and all components of the swimming pool.

When these products were submitted to the National Sanitation Foundation (NSF) for approval, the authorities thought there would be insufficient disinfection and oxidisation of the water in public pools, where the bather loads are high.

new age of technology is dawning - but are we ready to accept new attitudes and treatments in our swimming pools and spas? Alan Lewis recently attended the 15th Annual World Aquatic Health Conference (WAHC) held in South Carolina, USA where the National Swimming Pool Foundation focussed on aquatic research and education. Amongst the many topics presented was one on ultra-fine bubble technology (UFB).

Following, Alan gives us a brief outline on this new technology.

Without a doubt, ultra-fine bubble technology was the most significant of the technologies discussed, presented by Michael Geyer from Pure Vision Technologies for the first time at a WAHC. Also known as nano-bubble technology, this technology is not new and has been developing in many parts of the world, particularly Japan, for more than a decade in areas such as agriculture, waste water conservation and recycling, fish farming and cultivation, and aquaponics.

Now Geyer, who is based in Phoenix Arizona, has finally produced two devices for swimming pools and spas as well as bodies of water such as lakes, decorative pools and fountains.

Geyer reports that he has installed his products in well over 100 pools around the USA. The product for commercial pools is known as AquaGen, while Aqua Fuzion is for residential pools. Both systems dissolve oxygen into the water itself and discharge it in the form of tiny bubbles which are only one-tenth of a micron in size. They are too small to be seen with the naked eye and so Aqua Fuzion researchers need a sophisticated and a very expensive facility with which to measure the number of bubbles produced, using a laser beam to count the bubbles in the water.

It might be hard to believe, but we were told that these machines make roughly 100,000,000 ultra-fine bubbles in one millilitre of water!

Because they are so small, they cannot break the surface tension of a water molecule and hence remain in suspension in the water for weeks at a time.

WATER ENHANCER STATUS All-in-all, because of the huge number of bubbles, the collective sum of oxygen bubbles amounts to a large area of contact between the oxygen and particles, micro-organisms and contaminants that are usually present in swimming water.

However, Geyer decided to add ozone to the system to greatly increase its disinfecting capability. In addition, he added oxygen concentrators to the system so that indoor pools can also benefit from the purification of the air in the pool hall.

So these products were awarded NSF approval as a â&#x20AC;&#x153;water enhancerâ&#x20AC;?. At the same time, they required that the public pools or spas have a least 1.0 ppm of free chlorine in the water. So until it is proven that the combination of oxygen and ozone fine bubbles together are satisfactory, the addition of chlorine will remain the practice. By running ozone through the Aqua Fuzion, both the oxygen and the ozone molecules are atomised 1000 times smaller than typical systems.

It must be emphasised that where ozone bubbles are of larger diameter and visible to the naked eye, we know that these are not of any value to disinfection, because they would immediately rise to the surface and gas-off by breaking the surface tension of the water and joining with the rest of the oxygen in the air above the pool.

Therefore, the size of the bubbles is vital because when they are that small, they will remain in suspension much longer and are more likely to oxidise unwanted micro-organisms in the water.

Although it is not greatly significant, sensing of the ORP in this water is a good indication of the power of the bubbles to oxidise.

However, a pool running as described above will still need the 1ppm of free chlorine at this stage of the development of this technology. Beyond that, more research is needed to measure the effectiveness of the breakdown of organics in the pool.

We know that the oxygen bubbles are negatively charged, and hence will latch onto and surround organic positively charged particles which are present. The next step is to research the effects of millions of bubbles on cryptosporidium, giardia and other pathogens that frequent swimming pools. Since these pathogens are anaerobic, we can assume they cannot survive in a highly alkaline, oxygenised environment. What remains to be discovered is just how much oxygen is needed to do the job.

How to get a maximum result, with a minimum outlay

The task of determining the best pool heating choice for a commercial operator has become far more complex in the last decade. In the past, the equation was virtually as simple as installing gas for year-round heating or the typical rubber-mat solar collector for part season. Now the degree of choice has expanded considerably and encompasses new technologies such as heat pumps with inverter technology and solar-photovoltaic (PV) collector. Likewise, the increased sophistication of energy pricing adds to the equation. It is fair to say that the market itself has also become more robust. The levels of grey-noise, of claim and counter-claim, only serve to make the process of evaluation and understanding more confusing.

being made for the Waratah Apartments, Potts Point NSW. The apartments include an indoor pool and spa, separately heated.

Whilst this is a residential building, the pool and spa being open for daily use by multiple residents will reflect a very direct parallel for any hotel.

POTTS POINT APARTMENTS POOL AND SPA HEATING The Waratah Apartments is a luxury residential building in Sydney’s Potts Point district, with amenities including gym and sauna. The indoor aquatic facility which is the focus of our attention includes a 14.8M long pool heated at 28°C and spa, heated at 38°C. Presently, pool and spa heating is provided by electric element, with these heaters being housed in the internal pool plant room.

Check List Item 1: Understanding the heating requirement Understanding how the pool gains and losses heat by month and by what quantum, sets the parameters for any capital investment decision related to the pool heating system. This information allows current costs and potential savings to be defined. Seasonal factors which may be specific to a location or even tied to the pattern of occupancy may be identified which can influence the technology selection. The best record of the energy intensity of a pool is actual energy records but it is relatively rare for the pool heating system to have a separate

supply and meter. Typically, the pool profile is derived from heat load modelling and the most accepted methodology in the Australian context is the use of the UNSW Poolheat Program.

It is important the resort or hotel owner is confident in any heating data presented and if a simulation of the pool is presented, the assumptions underlying these results should be understood. Don’t accept that data that is simplistic or is too hard to interpret.

In the case of Waratah Apartments, Poolheat modelling of the pool showed a predicted heat load of 16.6kW in July, with a total energy use of 27,784kWhs/508GJs. Check List Item 2: Identify your technology options Both the pool and spa at Waratah Apartments are heated by electric element. Element heating is somewhat typical of older builders where the use of element reflected an easier pathway for the developer in terms of cost and installation (i.e. these are physically small with no ventilation or flueing type requirements) more so that a concern for ongoing efficiency.

Incidentally, changes to the National Construction Code (May 2014) saw element heating removed for new commercial buildings and the heating mechanism must now be one (or a mix) of solar, heat pump, reclaimed energy, geothermal or gas.

For Waratah Apartments, the current use of electric element clearly means that the electrical infrastructure would readily allow conversion to the electric heat pump. The feature of

element heating is a 1:1 efficiency so, for example, a 24kW element heater consumes 24kWh to produce 24kW of heat value to the pool water. By contrast, a heat pump operates at high efficiency so that a comparable 24kW output heat pump would use only some 5-6kWh per hour. Billed usage then falls from 24kWh to 5-6kWh, cutting costs directly by some 75%.

The physical surround can play a substantial part in heating system choices. For Waratah Apartments, the building layout does not allow for the installation of (rubber mat) solar collector nor is gas supply available so the definition of the project is narrowed to one of energy efficiency improvement by conversion from element to heat pump.

Check List Item 3: Breakdown your energy pricing The new competitive energy market price structures can be complex and far removed from the simple kWh or MJ pricing of the past but the onus is on resort and building managers is to understand the rates and rate structure applying to their building.

The means to do this is at hand as copies of prior electricity and gas bills do show not only the final bill total but the full breakdown of how the total is derived, i.e. the structure of pricing. Gas pricing is more simple and typically has a tiered structure, with gas pricing changing at different levels of gas use. Electricity pricing can also be tiered in terms of changing pricing by time-of-day (peak, shoulder and off peak) and by day of the week. Some electricity tariffs include a seasonal (summer/winter) structure. New contract pricing will include both Energy Rates (kWh based time-of-use based) and Network Charges, (both kWh and kVa) as well as various Regulated, Environmental and Metering Charges.

Waratah Apartments is a self-managed strata and the management team has been a very proactive and successful player in the competitive electricity market, negotiating a very attractive electricity rate. The electricity pricing for the building is based on relatively low Energy Rates (time-of-use) and Network Charges, both kWh and kVa based.

Check List Item 4: Determine the relative economics of your choices With the benefit of the heat load model of the pool created at Check List Item 1 and the overlay of the electricity pricing structure defined at Check List Item 3, comparative annual heating costs for the pool can be derived. Importantly, this predictive cost is specific to both the pool and the energy costs of the building/resort.

Where the primary options are all in play, the comparative cost data will include electric options such as element and heat pump and/or gas pool heating. The role of solar can be defined from this base data with the translation of the heat contribution of the solar collector to a month-by-month substitution for the energy cost of the primary heater (i.e. the solar transfer of the collector is measured as heating which offsets the cost of powered heat pump or gas pool heater). The offsetting amount must return an economic benefit in the manner of any other efficiency change as it cannot be assumed that the periods achieved of â&#x20AC;&#x153;freeâ&#x20AC;? heating in itself justify the capital expense.

The same principle apply to the potential installation of photo-

72

voltaic solar (in this case, justifying the capital cost in terms of the offset to power consumption).

At Waratah Apartments, the comparative heating costs for the two technology options left in play were calculated as â&#x20AC;&#x201C; heat pump $3,551 v element $18,371. Based on an estimated project cost of $20,000 installed, the estimated annual saving of $14,823 gives a payback in the order of 1.5 years of full costs.

Check List Item 5: Define your project specification With Check List Items 1 to 4 completed, we now have at hand a selection of technology based on robust assumptions, specific to the site in terms of load and energy costs applied. The next phase is to translate this to a project specification.

The project specification should outline a Scope of Works that clearly sets out responsibilities and expectations for the work.

It may define a selected heater brand and model and seek alternative competitive quotations for its supply and installation or allow the market to offer alternative brands. Where this second approach is taken, the critical aspect is that the heater capacity must demonstrably meet the heat load defined at Check List Item 1. Those companies quoting must be able to provide product specification information so that a clear apples-for-apples price comparison is achieved and that under-sized plant is weeded out.

The logistics of pool heater installation are relatively straightforward and the major variable is typically power or gas supply and possibly, ventilation aspects when plant is to be installed internally. Both of these aspects (if applicable) should be well and truly sorted before quotation stage as in truth, these costs should be embedded in the economic evaluation completed at Check List Item 4. Where supply is constrained, the costs involved could completely change the economic evaluation.

The Scope of Works should clearly define obligations for commissioning of the new heating system and hand-over training.

The Scope of Works would be best prepared having completed one or two walkthroughs of the potential installation by either the manufacturer or skilled installation contractors. Incidentally, our Case Study is at this stage, with inspection being made by Rheem as the potential heat pump manufacturer to confirm the logistics of the installation of this plant.

Check List Item 6: Select Contractors The Scope of Works would be issued to selected contractors who can demonstrate the skill set and experience needed for the successful completion of the project. If the management team has selected a brand/model, then the contractors may be limited to authorised installers or service agents so that they bring a strong level of expertise and training.

CONCLUSIONS Clearly there are many nuances to consider at each step in this process but the Check List should provide a template for a successful project, with the optimal choice made in heater type and capacity, with robustly tested and measurable deliverables.

WARMING YOUR POOL WATER HELIOCOL COMMERCIAL POOL HEATING

M

any commercial pool owners are realising their pools could be used more. Often the reason for this lack of consistent use is simple – the water may not be warm enough.

SO, WHAT ARE THE OPTIONS??

1. Gas Heating Gas heaters provide flexibility to the Commercial Pool Owner, because of their rapid heating ability.

Gas heaters can easily maintain any desired water temperature, as typical sizing is based on providing heater capacity capable of achieving a 14°C rise in water temperature in 24 hours.

This allows a cold pool to be heated to a beautiful 28°C - 30°C in around one day, even in winter. This heating strength makes gas perfectly suited for pools that are used for entertaining.

2. Electric Heat Pump Heat pumps work like a reversed air conditioner. They draw in large quantities of air from the atmosphere; extract the heat contained in the air and transfer it to the water from the pool or spa passing through the unit.

Heat pumps can provide energy to the pool that is many times the amount of energy they take to run. This factor is called the heat pump's co-efficient of performance or COP. Combined with their high-energy efficiency, heat pumps are also ideal for connection to off peak or time-of-use electricity pricing.

Solar

whenever the roof temperature is enough to pass heat to the water.

A Solar Heating System on a commercial pool provides the owner/operator with an environmentally friendly/low carbon footprint option. Its only running cost is the secondary pool pump to circulate the water to the solar collector.

Reputable pool heating companies will offer a free, no obligation analysis of the solar heating requirements. If an existing gas or electric heater is in place, this analysis should be accompanied by a report showing potential energy savings, return on Investment figures and environmental savings.

WHAT ABOUT A COMBINATION? A solar/gas or solar/heat pump combination is often favoured

by Commercial pool operators. A combination system provides the high energy savings of Solar with constant year-round pool water temperatures provided by a gas or heat pump system.

If a Commercial Pool Operator is already using a gas heater or heat pump, and wishes to now enjoy some energy savings, the solar system can still be installed.

An important component of the combination solar/gas or solar/ heat pump installation is the system controller. This device controls the operation of both heaters to ensure the maximum energy savings are drawn from the solar system whilst still allowing the pool to run at the operator’s desired temperature.

PERFECT POOL, common commercial sense MATTHEW WOOSNAM I POOLWERX

A pool and /or spa facility is a blessing for its public appeal and a burden for the responsibilities that go with it. It is important that you have fully trained and qualified maintenance staff caring for your pool at all times under any situation, under any bather load to ensure that your pool is sparkling and healthy. With the recent announcement and released new swimming pool and spa certification program all pool service maintenance staff will now be able to qualify for a cert III and cert IV in swimming pool and spa maintenance service. This is a national qualification which is aimed to lift the quality and standard of care of swimming pools. Make sure those who are looking after your swimming pools are qualified.

You will be able to contain cost at relatively predictable levels helping prevent disastrous surprises and to also reduce your own labour requirements.

via computer software programs which will automatically provide you with a far more accurate analysis of the results and also provide safe handling methods for applying the chemicals to the pool or spa. These reports can also be saved as a register of your testing and results for local authorities should they wish to inspect them at any time.

Whatever the size of your operation, it is important that you consider your own complexes individual circumstances and needs. You should consider on an annual basis the following...

4. T raining – With the recent evacuation of a Sydney 5 star hotel where by staff and guests were overcome by chemical fumes due to chlorine and acid being mistakenly mixed. This caused dangerous gases to enter the hotels air conditioning system, putting many people in danger and some were hospitalised. It is a timely reminder that all your staff are fully trained in the safe handling of dangerous chemicals involved in swimming pool maintenance. PoolWerx can assist in this area and often run Commercial Pool and Spa Operator Training (CPO) courses and can also assist with further onsite training. The following training is important for your hotel:

1. I nternal audit – Have a full and complete assessment of your pools current condition, suitability and state of equipment, maintenance regime, staff induction and training procedures, and recording of status and procedures completed. As each state now has varying legislation and guidelines, it is important you make sure that these audits are in line and cover the requirements of these.

Have you thought about an energy audit of your pool equipment and how much you can save by upgrading your pool pumps to energy efficient models?

DUTY OF CARE – NO ONE WISHES TO OPERATE A POOL WHICH IS UNHEALTHY OR UNSAFE Most pool operators do their level best – and beyond the occasional hiccup that appears to be adequate. Do you have a maintenance routine, pool rules, the requisite safety signage, first aid kit and so on?

However, the reality is that given the increasing complexity of regulations governing the operation of commercial pools, your facilities might not pass a government inspection, or your pool management measures may not stand up in a court of law should an incident occur.

Regulations vary by state and local council tend to change frequently – and the whole area is filled with shades of grey, virtually impossible for anyone but a specialist to decipher.

Whatever their good intentions, most operators unwittingly risk fines, orders, shut downs, and litigation by uses injured or made ill.

In essence this is an implication that management will act responsible and with all due care, to make sure the pool, spa, water falls or fountains, does not represent a danger to those likely to bath in it or drink the water. More importantly they must be able to demonstrate that they have records and monitoring systems, which show that correct procedures and tests were carried out regularly.

COMMON ISSUES OF OPERATORS A number of misunderstandings tend to surround management of commercial pools.

A large part of the reason is the changes in regulation have outpaced dissemination of information, and what was current yesterday may be out-dated today.

ARE THE REGULATIONS CLEAR? Many of the states and council regulations involve words and phrases like should or is recommended, suggesting operator discretion is permissible.

For example, it is not compulsory to have a formal pool and spa management plan put into writing, communicated to relevant staff, and readily on hand in case of an incident. However, it is universally regarded as reasonable and prudent to do so. In other words, you don’t have to have a formal plan, but you are vulnerable if you don’t.

HAVING THE RIGHT GEAR In every state, regulations dictate that your pools and spa equipment must be capable of handling peak bather loads in any conditions any time of year. Some guidelines/legislation is provided however there are still potential issues here:

78

• How confident are you that your equipment is still performing at the optimum level?

• Have bather loads changed over time?

• Is equipment becoming tired?

• Replacing one piece of equipment, even above specification can reduce the efficiency of the system as a whole if it is not fully compatible.

• Have you renewed equipment without attending to the pipes?

HOW DO YOU STAY UP TO DATE? Google your local government sites and download current regulations/legislation which will provide current and up to date information. Or contact your local PoolWerx owner to assist in this area.

WATER TESTING Test strips and 4 in 1 test kits are not regarded as acceptable analytical systems for commercial pools. Commercial pool testing must be photometric, or colourmetric. Even the smallest pool is expected to be tested at least a minimum of twice a day.

Large pools with heavy bather pools may be expected to be tested hourly.

MICROBIOLOGICAL TESTING It is not well known that commercial pools must be microbiologically tested on a regular basis by an approved National Association of Testing Authorities Laboratory.

PoolWerx can arrange regular microbiological testing for you.

INSURANCE If you check your public liability policy you are likely to find a standard condition along the lines that “You shall comply with, all laws, by laws, regulations and recognised standards for the safety of persons or property and maintain all premises, fittings, plant and equipment in sound condition”.

In this case, if you are not fully compliant at any point of time, your insurance might be compromised.

100% PROOF It is vital to be able to produce comprehensive evidence of care including hard copy log books, or computer records. Or even greater value is evidence that an expert 3rd party has been retained to oversee your swimming pools and spas.

CONTROLLED GROWTH

with optimum water quality TIM BATT WATER SOLUTIONS

This case study looks at the cityfit swim school however its content regarding the improvement of water quality can be related to any hotel pool.

T

he Cityfit Swim School in Bathurst offers a valuable service to the local community. In operation since 1990, the school's mission is to deliver a competency-based 'learn to swim' program that enhances students' ability to have fun and survive in and around water.

The school's owner and operator, Gary Webster decided that although water quality had always been good, constraints with the current treatment system would not support the increase in patronage and bather numbers that he was looking for. He began to research solutions and — after speaking with potential suppliers and other swim school operators — determined that a treatment plant upgrade would enable him to grow the business, while improving water quality. Webster elected to work with Tim Batt Water Solutions (TBWS).

TBWS assessed the current setup and elected to arrange the installation of a UV system for chloramine removal, as well as a chemical control system upgrade to facilitate superchlorination and remote monitoring and control, as well as automated record keeping. Components included a Wallace & Tiernan Barrier M525 medium pressure UV system, a BECSys5 controller and PC software, as well as the BECSysNow! mobile app.

The UV system is designed for easy installation directly into the filtered water line going back to the pool. With horizontal or vertical positioning options, it features 'light trap' stainless steel elbows on either side and a safety glass strainer immediately downstream. Since installation, Webster has reported a significant drop in chloramine levels — it now typically runs in the combined chlorine range of 0.2-0.6mg/L, well under the NSW Health maximum allowable level of 1.0mg/L. Webster also noticed an increase in pool water clarity coupled with a reduction in chlorine odour — both in the air and on bathers' skin after swimming. Analysis also shows that the ORP

80

mV rate of disinfection has increased by 20-30mV, meaning the chlorine is now working more effectively.

The chemical control system upgrade meant moving from a well-proven Strantrol controller to the same manufacturer's BECSys5 controller, as used at the Gold Coast Aquatic Centre in this year's Commonwealth Games. The controller provides pH, ORP mV, free chlorine and temperature readouts as standard with capacity for additional optional sensors that measure total/ combined chlorine, TDS, turbidity, filter plant flow, pressure and vacuum. The BECSys5 also provides the ability to set-up automatic superchlorinations at night if they are ever required.

One of the most useful and unique controller features is the inclusion of Ethernet connection via ‘BECSys for Windows’ PC software and datalogging. The free software enables remote monitoring of the pool from connected computers or via a mobile device. Connection to a PC gives the added benefit of remote control of the Sys5 settings, including continuous graphing of all readings and events. This advanced automatic feature takes the form of a building management system graph, with the ability to zoom in on time/days and to customise reading and event data presentation.

Webster sees great potential for remote monitoring when he is away from the facility, allowing him to check current water chemistry levels at any time, from anywhere. He can easily remind staff to make changes if any are required, as well as convert system-generated email alarm notifications to text messages for mobile devices if necessary. Webster has found that the monitoring system is also reducing time required in the

plant room by enabling constant and accurate pool condition data.

Investing in the latest equipment has delivered immediate efficiencies, giving Webster the opportunity to grow Cityfit Swim School while still delivering better water quality for patrons - a win-win situation for Cityfit and it's clientele.

Incredibox: a box chock full of innovation Today guests, from the AB socioeconomic demographic to the XYZ generations, overwhelmingly use their smart phones and apps to book rooms, check in, order room-service, open the door and close the curtains.

Legacy research that once showed a guest’s preference for modern technology and Wi-Fi, has fast become redundant, overtaken by the fact that guests have come to expect it and accommodation decisions hinge-on a hotels’ tech-credentials.

Tech-savvy housekeepers and managers know, technology reduces operational costs. Smart cards save cutting keys and smart rooms reduce energy and environmental impacts.

Hoteliers at the forefront of innovation are incorporating myriad features such as motion-activated air-conditioning, spacesaving motorised beds, elevator music that adapts to the mood, interior keypads for personalised music and lighting,

instant-frost shower walls, flat screen TVs embedded in bathroom mirrors and iPad concierges.

Virtual fitness classes, purified airsystems and digitised lighting to help ease jet-lag have been introduced in Europe, as well as streaming services, electronic wrist-bands to unlock the door – and in a hotel in Amsterdam, the City Hub, guests use a smart wrist-band to pull themselves a beer.

Fortunately technology is the nexus where both guests and housekeepers’ needs align with innovation bringing mutual cost and convenience benefits.

Small-size rooms compensate with many high-tech conveniences, such as personalised iPads and smartphones that travel outside the hotel.

Hotels are increasingly investing in interior appliances as space is at a premium. The once trendsetting capsulestyle hotel room is the new norm, along with robot check-ins.

Innovation is reflected in Weatherdon’s Nero Qi mission control in a sound-box.

BUY NOW. PAY LATER The accommodation industry is living in dynamic times. Never have we seen such disruption. With ever-growing diverse marketing distribution channels and the roll-out of AI telling us more and more about guest behaviour. If that’s not enough, we are also experiencing a once in a life time hotel building boom, introducing a massive uplift in contemporary design and leading operating and guest room technology.

Operators are under enormous market and social pressure to build their value preposition with the implementation of ontrend upgrades and refurbishments.

A new hotel industry start-up www.rubixpay.com.au founded by veteran hotel designer and furniture contractor, Peter

Carmody has established a payment solution to allowing managers to buy now what they vitally need and pay over a 3-4 year term.

"Our business hypothesis" says Peter, “is that managers are keen to buy equipment they need now to improve their guest experience and then to make repayments over time from the uplift in trading their receipts."

“It doesn’t make sense if you’re in the business of selling sleep and your beds are tied, that you wait around for fresh cash to replace them when managers can buy all the beds they need now at a cost as little as .73c a day over a 4 year term “ says Peter.
