FEBRUARY 2024

Just a month into the new year, and we're already observing emerging trends in architecture and construction. Notably, surfacing is an area ripe for innovation, especially with the upcoming Surface Design Show. The event, featured in our January issue, promises exciting insights into industry advancements. We're thrilled to attend, explore the exhibits and listen in on the comprehensive seminars lined up.

In this issue, George Emms, Specification Sales Leader at Polyrey, part of Wilsonart UK, taps into the world of surfacing, specifically for refurb and retrofit projects. On page 32, he runs through the different types of suitable engineering surfaces available on the market, explains the practicality of each and covers some of the regulations frequently encountered when working on such projects.

Elsewhere in this issue, Lee Davies, Director at Attain RTC, looks at the argument of desktop studies versus physical testing, explaining all the benefits of real-life testing along the way; Colin Brown, Head of Planning & Development at Carter Jonas, offers his insights on the Revised National Planning Policy Framework (NPPF); and we talk to Will Poole-Wilson, Managing Director at Will+Partners, about his architectural journey.

uilding on the innovations of the Striatus bridge, Phoenix is constructed from 10 tons of recycled materials, including recycled aggregates from the original blocks of Striatus. Using its ECOCycle circular technology, Holcim developed a proprietary concrete ink for Phoenix that incorporates an optimised low-carbon formulation with a 40% lower CO 2 footprint compared to the 2021 bridge and a carbon footprint that is 25% lower than the original structure.

Circular construction, using computational design and 3D printing, allows for a reduction of up to 50% of materials used with no performance compromise. Circular by design, Phoenix stands through compression without reinforcement, with blocks that can be disassembled and recycled.

Pheonix is a collaboration between Holcim, Block Research Group at ETH Zurich, Zaha Hadid Architects Computation and Design Group (ZHA CODE) and incremental3D. The Pheonix bridge is the latest milestone

by Holcim and its partners in their work to develop low-carbon structural solutions at every scale.

Shajay Bhooshan, Head of Computation and Design Group at Zaha Hadid Architects, says: “Phoenix is a significant milestone in technology readiness. It showcases the maturation of integrated design to construction technologies that were initiated with Striatus. There have been improvements in the robustness of the digital design tools, 6

ARCHITECT IN PROFILE

Here, we talk to Will Poole-Wilson, Managing Director at Will+Partners, about his architectural journey.

Explore his career, influences and notable projects, as well as his human-centric design approach. Gain insights into the challenges of sustainability in architecture and his vision for the future.

WILL+PARTNERS

WILLIAM POOLE-WILSON IS THE MANAGING DIRECTOR AT WILL+PARTNERS

Please tell us a bit about your career background.

I trained at the Bartlett, where I made many of my architect friends. In 2007, I was invited to be an Equity Partner in Pringle Brandon, which we sold to Perkins+Will in 2012, setting up Will+Partners in early 2018. In 2023, we merged Will+Partners into Broadway Malyan to look after its corporate interiors and commercial refurbishment.

At university, I developed a deep love for sustainability and wellness, which have always been my predominant research subjects. Nowadays, we very much encourage all our employees to have a similar research subject to exist alongside their architecture.

Have you always wanted to pursue a career in architecture?

I have a passion for drawing, and buildings, diggers and construction for as long as I have known. As a child, I’d always just be playing in the sandpit. It wasn’t until I really thought about university that I realised that architecture might be the thing I wanted to follow. I also had a fascination with design and the human relationship that comes with it. My passion for the arts and the series of scrapbooks I started to make deepened my love for the subject, along with reading and reviewing Victor Hugo (I love his drawings as much as the words), Van Gogh and Frank Lloyd Wright.

www.willandpartners.com FC& A – FEBRUARY – 2024

Who has been your greatest influence and source of inspiration?

If I must pick one person, it is John Drew. I have worked with John for over 15 years as a partner, and he has been more than exemplary to me, whether it’s the ability to harness his knowledge from projects such as the Walkie Talkie (he designed this at Rafael Viñoly) or Battersea Power Station (he did the concept design and detailed planning at Rafael Viñoly) through to a designer just talking to a designer, John is always there. As for my greatest 8

source of inspiration, it is probably the human race and how we design for the human experience. Whether that’s about a net-zero future or a truly healthy building, I am inspired every day by the positive outcomes we can generate as architects and designers.

What has been your most notable project to date?

There have been a few, so it’s hard to pick.

I really enjoyed my work with Goldman Sachs designing its offices, working on Macquarie at Ropemaker, through to a more recent project at the British Red Cross (BRC) HQ in London. At the latter, we were inspired by the work of the volunteers. There was a need to create a space that supported them, making sure that it was sustainable and recycled and protecting the needs of the BRC people for their future. It certainly was a very fun project with a magical team.

How do you approach your projects?

I approach all projects through humancentric design and a beginning where we, as architects, are merely the translators of the client brief and design vision. Design is the exploration of possibilities, and we explore everything, even the awkward and that design edge. Without that, we are just ordinary, and human beings are extraordinary. Design, for me, is like being the best human you can be, and that perhaps manifests as the exploration of form, function, materials, innovation and experimentation, creating the extraordinary. Sometimes, that is simply about inspiring the team around you.

INDUSTRY UPDATES

What do you think is the greatest challenge for designing in sustainability?

The greatest challenge is that there should be no necessity for a platform to speak on the subject other than thought leadership, and I hope that the next 25 years prove that.

We design so well that the sustainability stage for the built environment is taken away entirely, and we just do the right thing. Perhaps, realistically, that will be a stage where we genuinely discuss the direction of travel and how we maintain carbon net zero, but we are a long way away from that. I do hope we embrace new technologies, such as hydrogen or small nuclear power sources, and celebrate the innovations in these fields more.

What is your favourite building and why?

My favourite building is probably the Pantheon in Rome. It has a dome that was the largest in Europe for centuries, and it has a hole at its centre called an oculus.

Its design is all about celebrating a form of human experience. Its dome is made of concrete and serves as a reminder that we can discover technology and lose it or, perhaps more importantly, the importance of sharing knowledge so that we don’t lose it.

What do you think is the greatest challenge for architects today?

Being architects. We need to remember that the entire process of design is architecture. Sometimes, I think we slip to the point that it is only about an aesthetic design. Or worse, we forget to listen to and educate the client about what design is.

We need to inspire more.

What do you think is the greatest challenge for architecture students?

One reason I am so invested in the concept of our academy is that I am troubled by the cost of studying architecture today. I wonder whether I could afford to study the subject myself in today’s economic climate. This only serves to make it an elite subject, and this is why I am so encouraged by the possibility of making architecture attainable through apprenticeships and a practising academy.

What advice would you give to newly-qualified architects?

Draw by hand, make models and make AI your critical friend.

9

What can we expect to see from you over the next year?

We have some exciting and innovative projects in our pipeline; we are exploring with some success the new boundaries that AI provides for design. We have new ideas coming to fruition in our thought leadership around sustainability and a new approach to net zero. I expect to grow our next-gen team even further and inspire others throughout the industry to do the same. Above all, we hope to have real advancements in health and wellbeing and our approach to design.

VOICE OF THE INDUSTRY

TESTING, TESTING

LEE DAVIES IS THE DIRECTOR AT ATTAIN RTC

Manufacturers providing products or systems to the UK construction industry have traditionally relied significantly on the expertise of testing houses, or rather the TIC (testing, inspection and certification) industry, to determine the published fire performance, for example, of products and systems. Furthermore, for many years, manufacturers have relied on desktop studies rather than testing the full suite of the range, as this saves both time and money. However, since the changes to the UK’s national Building Regulations over the course of the last six years, there has been even greater emphasis on the need to conduct actual physical testing to obtain empirical data, resulting in a move away from desktop studies.

ATTAIN RTC/CA GROUP

T

oday’s advice from leading authorities and associations, such as the RIBA (Royal Institute of British Architects), remains not to accept desktop studies, instead requesting actual testing and certification when designing buildings and determining the performance characteristics of products and assemblies, particularly in reference to fire performance.

This is now supported by the latest revisions to our national Building Regulations, which have prohibited the use of desktop studies for ‘relevant buildings’ requiring actual tests to demonstrate the compliance of building products and solutions. Without a doubt, this is a positive step to prevent dubious claims regarding the levels of performance of products and provide greater confidence in the true performance of systems.

With these changes in national Building Regulations, there is a drive to use harmonised European standards. Certainly, for the standards for fire performance, reaction and resistance, this makes real sense. British

FC& A – FEBRUARY – 2024

12

standards have been used in some instances for almost 50 years, but does that mean they should be obsolete? There are many equivalent European standards; some have even evolved from British Standards, and now some believe they are the de facto standards all product manufacturers should be working to. This may not apply in all cases. One should speak with the preferred providers to ensure testing is to the most relevant standard.

From some of these European standards, there is a perception that it is necessary to achieve Euroclass A1-rated systems across a wide range of construction products, which we have seen in many instances over the past few years, simply because this is perceived to be the best. There are actually no requirements in Building Regulations for this. Indeed, there is no one standard, British or European, which sets a test method or series of tests to establish a Euroclass A1 rating for a given system. Maybe it’s time for the manufacturing, construction and TIC industries to come together to establish one.

VOICE OF THE INDUSTRY

Inevitably, the burden on research and testing facilities is ever increasing, resulting in ever-extending lead times for all types of testing across the whole market. Unfortunately, as the TIC industry has limited testing facilities available, this has generally had several significant effects, including an increased reliance on specifications, a reluctance to change to alternative solutions and increased use of established solutions. Ever-extending lead times in testing facilities does not help the reputation of the manufacturing and construction industry in the UK. We need additional capacity in the UK. Otherwise, the costs to manufacturers will increase as their need to bring new products to market will drive testing overseas, which becomes more and more costly.

Without additional UK capacity, there is a real and tangible risk that the market, in the face of increased lead times and cost associated with testing, could witness a reduction in innovation. At a time when other aspects of Building Regulations are changing, and the performance of building envelope solutions is evolving to meet environmental and sustainability objectives, this could create an unhealthy divergence between demand and delivery.

There are a number of investments taking place currently in the UK, but there is only one that covers many aspects of the testing required in the UK today. Attain RTC is a new testing facility established in north Yorkshire to help address the need

for tested solutions and products. Setting up such a centre is not easy, comes with many challenges and has a high threshold for achieving the necessary accreditation.

All services are delivered from a stateof-the-art 40,000ft2 construction material testing laboratory using the latest technology and software to deliver comprehensive and efficient services to clients. The testing services include fire resistance using the most efficient technology available, reaction to fire, acoustic properties, facade mock ups for water and air ingress, physical load testing and endurance.

The goal at Attain RTC is to provide a safe working environment for its employees, manufacturers, contractors and visitors alike, whilst setting an industry benchmark for quality of service.

While others are extending lead times, both in terms of testing and reporting, we seek to buck the trend and offer lead times that match our customers’ needs. Attain RTC recently accomplished a massive milestone, achieving UKAS accreditation in a very short space of time, thanks to the drive of the business, supported by a highly-competent team versed in construction products testing, determined to deliver quality service to our customers. Test methods and standards covered by the scope will grow, but for now, we can provide formal or indicative testing in reaction to fire, resistance to fire and acoustics.

13

With new testing capacity coming in to serve the increasing demand, we hope that innovation, in the face of an increasingly challenging market, can be encouraged rather than hindered.

DECODING THE REVISED NPPF Here, Colin Brown, Head of Planning & Development at Carter Jonas, offers his insights on the revised National Planning Policy Framework (NPPF).

CARTER JONAS

I

was pleased to have attended the launch of the revised NPPF at the RIBA in London in December and confess that, contrary to my initial expectations, I was moderately encouraged by the greater certainty that it will provide to developers, housebuilders and land promoters. Having made that bold assertion, we will have to wait and see how this all plays out on the ground, so I reserve the right to change my mind.

Ordinarily, Governments might be expected to sit on the fence and bide their time as they approach a general election.

Alternatively, they could seek to become more radical in their position, providing a stark contrast to that of the opposition.

However, in my opinion, Michael Gove’s announcement did neither. After almost a year of distinct uncertainty pending the response to the consultation on the NPPF, we finally have some direction, even though some elements of the announcement do appear to be flawed.

Counter to expectations, the Government has not completely given in to the NIMBYs. In retaining the Standard Method as a starting point in assessing housing numbers, reasserting the 300,000 homes per year target, introducing league tables for LPAs, retaining the housing delivery test, putting two further LPAs into special measures and requiring seven local authorities to come up with an urgent action plan relative to the preparation of new local plans, the secretary of state has sought to demonstrate that he is committed to growth. He even went as far as to declare himself a YIMBY! FC& A – FEBRUARY – 2024

The willingness of the Government to intervene and propose a new approach to planning in specific locations is encouraging at a time when the sector had become increasingly concerned that entrenched and slow, local decision making was delaying much-needed development. This new approach is discernible both in the decision to fasttrack significant new development in Cambridge through the establishment of a development corporation, and through the increased use of special measures where local delivery has proven to be poor.

Having spent the majority of my career as a planning consultant in Cambridge, my experience with planners and politicians at Cambridge City Council and South Cambridgeshire Council has generally been very positive, but I confess that I can see that a development corporation is likely to be necessary to take on the challenging task of more than doubling the size of the city (especially in view of the significant amount of green belt that surrounds it). I do think it will, however, be important to ensure that the proposed development corporation seeks to work with local leaders and councils in a collaborative and joined-up way.

So, as we approach the next general election, it would seem that the divide between the Conservative and Labour parties on housing delivery is perhaps lessening. In fact, both have asserted that they are ‘on the side of the builders, not the blockers’ while, of course, accusing each other of precisely the opposite!

14

COLIN BROWN IS THE HEAD OF PLANNING & DEVELOPMENT AT CARTER JONAS

Blockages do potentially remain, of course, not least the ability of LPAs to ignore their standard method of housing calculation on the basis of arguing that accommodating such levels of growth would be inappropriate to local character. Equally, where an authority is a predominantly green belt authority, it seems they may be able to duck the need to deliver much-needed housing.

This would be highly regrettable and runs the risk of leaving a generation without suitable housing choices.

Despite this, the Government appears to have taken the view that there will be some votes in facilitating, rather than blocking, development – making the publication of the new NPPF a more positive development if the proposals can be delivered as intended.

COBE AND YELLON WIN COMPETITION TO DESIGN RESIDENTIAL TOWER AT STOCKHOLM’S HISTORIC GASWORKS Danish and Swedish architecture firms Cobe and Yellon have been announced as winners in the competition to design ‘Stadsljus’, a new residential tower rising 110m above sea level situated on the site of Stockholm’s former historic gasworks. Announced by OBOS, one of the largest housing developers in Scandinavia, together with the City of Stockholm, the project is set to redefine the flat city fabric of Stockholm while paying homage to the historical significance of the site. The tower will house approximately 300 apartments of different sizes alongside a ground-floor restaurant and nursery. Its distinctive circular shape draws inspiration from the historical gasholders of the site.

COBE AND YELLON

A new circular landmark in Stockholm Located in Stockholm’s Royal Seaport, one of the city’s largest urban redevelopment areas in the north east of the Swedish capital, the site has been an industrial area characterised by gas production for over 100 years. In operation until 2004, the site features several distinctive cylindrical gasholders with significant architectural and cultural value; among them are Architect Ferdinand Boberg’s two brick gasometers from the late 1890s. Some gasholders have been preserved and FC& A – FEBRUARY – 2024

repurposed, while Gasholder 4 has been demolished and is to be replaced with a new residential building named Stadsljus (meaning city lights), with the same height as the former holder.

The residential tower rises 110m above sea level and will have a significant impact on Stockholm’s cityscape. Its circular design not only pays homage to the site’s historic gasometers but also contributes to a cohesive family of circular buildings on the former gasworks grounds. With three bundled cylinders, Stadsljus becomes the next-generation 16

gasometer within a volume ideally suited for housing.

Chief Architects from Cobe and Yellon, Dan Stubbergaard and Fredric Scherman, say: “With its combination of three cylinders, Stadsljus is an interpretation of the historical gasometers from the site. The residential tower not only reflects the essence of its time and purpose but, standing alongside its historic counterparts, forms a harmonious family of gasholders that will grace the Stockholm skyline while enriching its local surroundings.

STADSLJUS, COBE AND YELLON

Housing for people in all phases of life The building contains approximately 300 apartments of various sizes – from spaceefficient studios to spacious apartments.

20% of the apartments will be offered through a co-ownership model, making it possible for more people to buy a home in Stadsljus. The design’s three clustered cylinders feature optimal conditions for natural light within each apartment. Its distinctive shape allows for units to face multiple directions, with spectacular panoramic views over Stockholm, while many units have one or more terraces.

CEO of OBOS, Daniel Kjørberg Siraj, says: “After a thorough and comprehensive process in collaboration with the City of Stockholm, we are now very pleased to present the winning entry for Stadsljus. The winning team has succeeded in combining contemporary residences and high architectural quality with a strong connection to the culturallyand historically-valuable site that is the gasworks area. With residences in various sizes and price ranges, Stadsljus will

become a home for people in all phases of life, and that is how we, as a member organisation, want to build homes.”

Reflecting the context The tower is composed of a distinct base, body and crown inspired by the surrounding gasometers. An open brick base draws inspiration from the brick facade of the historic Boberg gasholders and contains public functions such as a restaurant and a preschool. Inspired by the rational and repetitive steel skeleton of another nearby gasholder, the body of the tower consists of a modular, threedimensional metal facade, subtly capturing daylight on its angled surfaces. Finally, the crown is a tribute to the top of the Boberg gasholders with a faceted and pitched roof and a pronounced overhang, making a distinctive mark on Stockholm’s skyline while featuring solar cells and concealing technical devices.

The construction utilises a modular and prefabricated facade assembly system, which is efficient in terms of time, economy, production and precision. The facade is 17

composed of a modular skeleton containing closed wall panels, windows, doors and balconies that allow for various configurations to strike the right balance between variety and rationality while ensuring optimal indoor climate in each apartment.

The construction is planned to start in 2026, with occupancy starting in 2029.

THE COMMON ROOMS, ARTEFACT

Photographs: ©Jim Stephenson

INSIDE THE COMMON ROOMS Access to public and social spaces is vital to community cohesion and our individual and collective wellbeing, yet in London such spaces are in short supply. To address this, the result of years of underinvestment in our communities’ social infrastructure, the charitable organisation Clapton Commons was formed to bring the diverse community of Stamford Hill together, founded on the principle that what unites us is greater than what divides us.

ARTEFACT

T

he charity is rooted in the ancient tradition of the common land and the concept of the common good. To be ‘common’ is to be able to engage with others, and the ‘commons’ is traditionally a place where people from all faiths and none can come together, where many voices can be heard and hope shared.

Born out of these principles, the Common Rooms is a new home for the community to grow together, designed by local architecture studio Artefact. It comprises a series of rooms beneath St Thomas’ Church, a beautiful Modernist, listed building in the geographic heart of Stamford Hill.

Noted for its atmospheric nave, designed in the late 1950s by the revolutionary church Architect Nugent Cachemaille-Day, St Thomas’ was blessed with an extensive but underused undercroft.

To revive this large, empty space and catalyse the renewal and rebirth of the church as a building rooted in the community, St Thomas’ came together with Clapton Commons and Artefact Founders Benedetta Rogers and Daniel Marmot. Together, they aimed to transform the overlooked undercroft into a valuable and versatile community resource: the Common Rooms.

The key design ambition of the project was to create an uplifting sequence of carefully-designed, high-quality spaces that could form a joyful backdrop to the social life unfolding within. Financing for the Common Rooms was secured through FC& A – FEBRUARY – 2024

a combination of support from the GLA, Hackney Community Fund and The Clothworkers’ Foundation and a £55,000 crowdfunding drive led by Clapton Commons.

Now complete, the Common Rooms offers a compelling case study on how to create beautiful and practical spaces for social connection with a limited budget – as well as a demonstration of Artefact’s expanding interest and expertise in communityenriching architectural projects.

THE COMMON ROOMS, ARTEFACT

Benedetta Rogers, Director at Artefact, comments: “As architects, we really believe in the importance of community-led spaces – spaces where all sorts of activities can take place, where rituals are performed, and new possibilities and connections are created, strengthening a sense of community and belonging.

“Clapton Commons is a fantastic grassroots organisation, and it has been wonderful to support them in creating a much-needed place for the community to come together.

With shared values around enacting positive social change, we have relished the opportunity to put our design skills to good use in the service of this community.”

Elevating everyday materials and uplifting space The principal design ambition was to create an uplifting place that reflected the needs of its diverse users and had a quality that belied its constrained budget. Through carefully-considered, bespoke detailing, Artefact elevated costeffective materials to create a place that feels unique and helps to define a new identity for Clapton Commons.

The partitions were constructed from off-the-shelf timber sections, with polycarbonate clerestory windows whose details and rhythm echo the design of the garden room in the church above. Wood-wool panels help to absorb sound across the large spaces, and a joyful colour palette helps to enliven the undercroft and compensate for its limited daylight.

A bold blue column with expressed copper piping in the centre of the space creates a moment of curiosity, as it supports the baptism font of the church above, while the servery projects from the kitchen into the canteen, celebrating the moment food is served.

Daniel Marmot, Director at Artefact, adds: “Our main aim with the design was to encourage unexpected encounters through the spatial planning, and to forge a new identity for Clapton Commons through the character of the architecture.

“We located the dining room at the heart of the scheme, where the community comes together to cook and break bread. It is the nucleus around which the other spaces revolve, ensuring different users rub shoulders and make connections when circulating through the building.

“We developed a vibrant, varied colour palette to reflect the optimistic outlook of the client and community, and to uplift what was previously a gloomy undercroft. The rhythmic partitions are a technicolour FC& A – FEBRUARY – 2024

reinterpretation of a detail in the church, and the continuous clerestory ensures light permeates between rooms, as activity spills from one space to another.”

A space to strengthen connections Artefact’s bold new signage draws visitors from the street into a mature courtyard garden, where a new entrance door with a distinctive colour palette of earthy reds and pinks leads into the Common Rooms.

In the diverse and disparate community of Stamford Hill, the Common Rooms aims to strengthen the web of social connections in the neighbourhood by fulfilling multiple uses and serving multiple sections of the community.

The architecture of the space encourages unexpected encounters and new social connections to form.

A constellation of smaller rooms encircles and opens into the central canteen at the heart of the space, reflecting the importance of a community dining together. There is space for people to cook together in a new kitchen, hold both intimate and large-scale public meetings, for tenant clubs from neighbouring estates to meet, for care in the community, exercise in the studio, dance, make music, learn new skills and share hope in each other.

Joe Walker, Director at Clapton Commons, says: “The Common Rooms has always been about more than just bricks and mortar and making an underused space look architecturally beautiful. That, of course, is important, but working with Artefact, we were able to develop a vision for a community hub as a space where people could come together, action could be witnessed, and hope could be shared in transforming the neighbourhood and the lives of people we work with. This is our common purpose – to give people more control over their lives and to foster a sense of shared ownership of civic and community space.”

The programming and management of the Common Rooms are now being handled in collaboration with the local community. By incorporating a variety of spaces at different scales, the Common Rooms is inherently flexible, able to evolve over time with the changing needs of the community.

The Common Rooms is the first phase of a wider transformation of St Thomas’ Church and parish hall. All the works to the undercroft are designed to be easily demountable should the requirements of users change as further improvements are delivered.

LIGHTING & ELECTRICALS

BATTERY AFFORDABILITY IS TRANSFORMING SOLAR POPULARITY Commercial organisations have been slower to adopt battery storage than the domestic solar market, primarily due to storage capabilities and affordability. Yet that’s now changing. The challenges once faced are easily remedied, according to Richard Williams – foremost an engineer – as well as Founder and Managing Director of Aztec Solar Energy, the nationwide engineeringled consultancy and installer of bespoke solar photovoltaic (PV) and battery energy storage systems (BESS). Based at the University of Warwick, Richard has over 30 years' experience in the energy services sector and shares his views on how battery storage is helping deliver more economical and sustainable solar energy solutions.

AZTEC SOLAR ENERGY

T

he economic attractiveness of solar energy has accelerated over the last five years, with more businesses adopting it to combat rising energy costs and deliver long-term energy security. Until now, the expense of installations, the difficulties of a retrofit and the lack of energy storage have been barriers, but that’s no longer the case. Installing rooftop solar power is one of the best investment opportunities available.

Batteries have become much more competitively priced, and rather than return the energy harvested to the grid – which isn’t always the best price – they allow energy to be stored, and organisations can draw on it as needed and accommodate peaks in demand. Batteries can be force charged overnight at lower electricity rates and the energy used in the day when electricity rates are higher.

FC& A – FEBRUARY – 2024

LIGHTING & ELECTRICALS

From flood to motion-sensor lights Solar energy can be used to power a wide variety of lights.

Most floodlights are CLF (compact fluorescent lamps), HID (highintensity discharge lamps) or LED (light-emitting diode bulbs). HIDs have a shorter lifetime than LEDs but often provide a brighter light. Solarpowered motion lighting is designed to illuminate only when it detects a motion, contributing to further reductions in usage and costs.

Above all, you will not be restricted by the types of lighting you can use through solar-generated power.

Lithium-ion or lead acid battery Lithium-ion technology can be more expensive as an upfront investment; however, the lifespan of lithium-ion outweighs the cost of installing lead acid. These batteries are constantly developing and come in various sizes.

Even if you already have PV panels, battery storage can be added retrospectively. Many are taking this option as the economies of scale with battery production is bringing prices down and making them a cost-effective solution. Batteries have reduced both in cost and in size by at least 40% over the last five years.

Such affordability and improved accessibility are driving organisations to reconsider solar and battery use across the board, particularly where extensive lighting is a necessity and required over long periods. Using solar energy on demand provides a greener energy alternative whilst removing perceived barriers and is transforming the use of power in large manufacturing and production plants, through to car parks and airports, and throughout communities, including hospitals and sports grounds etc. in a way that’s not been seen as economically viable previously.

Should you be considering greener options, here are some primary considerations when evaluating a move to solar battery energy usage:

How it works Solar battery systems monitor usage and store the excess energy from your PV system, automatically diverting excess energy to your battery rather than back to the grid. The battery system distributes the stored energy when it detects a demand greater than the PV system can provide or when there is no PV generation, assuming there is sufficient energy stored in the battery. New battery systems allow you to prioritise this.

What’s the primary function?

If ever there was a place where solar lighting proves its value, it’s providing lighting over long periods of time. Consider how the lighting is going to be used and the frequency of operation.

You may be looking to illuminate a large site/ plant 24/7 or highlight a designer lobby or exterior buildings intermittently. Determine the specific functionality, including the levels of light required at different times, dimmable options versus high-level, bright illumination and the length of time it will be operational.

Initial assessment It’s important to establish a comprehensive power usage plan across the board, with an accurate evaluation of current and future energy needs, including those affected by any future lighting installations. Predictive modelling will assist in establishing the correct solar panel and battery installation to deliver long-term energy security.

Installation and maintenance While there are upfront costs to include solar panels, inverters, batteries and installation for solar-powered lighting, these have come down in price over recent years, and maintenance costs remain very low. Little effort is required other than cleaning the panels and periodic annual maintenance checks.

Cost-effective reliability Solar energy does help reduce energy bills in addition to working towards an improved energy profile. As solar energy is still collected on cloudy and rainy days, the option to store this energy and call on it at peak times is now a cost-effective solution. The ability to force charge a battery means savings can be made using stored energy during periods when energy rates are higher.

23

Battery management system The battery management system (BMS) provides oversight to the battery pack. It keeps the battery within the safety operation region in terms of voltage, current and temperature during the charge, the discharge and, in certain cases, at an open circuit.

Battery size, storage and warranty This should be matched to your electricity usage and the size of the PV system. Warranties will be dependent on the manufacturer; typically five to 10 years.

Inverter size The PV inverter converts the variable direct current (DC) output from a PV panel into an alternating current (AC). Its size dictates the push-pull capabilities and size of the battery and should be matched to the usage pattern of your building/site demand.

Safety Follow the manufacturer’s instructions, and both lithium-ion and acid batteries are equally safe. Batteries need to be taken care of and protected from damage, operating in extremely hot conditions, and overcharging.

As long as you have a battery management system installed, there’s little to worry about and much to be gained.

HVAC

The Empire State Building in New York was an early adopter of the technology and is in the process of converting more of its hydronic systems to nano-tech heat transfer fluid

CLEVER TECH TURNING HYDRONIC HVAC SYSTEMS INTO ENERGY-SAVING POWERHOUSES Reducing the energy consumption of buildings doesn’t have to be complicated or prohibitively expensive, as a new approach to cutting fuel bills and lowering carbon emissions is demonstrating, says Dominic Wish, HMX UK’s Technical Director.

H

ydronic heating and cooling systems (those using water as their primary heat transfer fluid) are at the forefront of a movement that is delivering energy and carbon savings of between 20 and 35%, with some projects returning savings far in excess of this. The average ROI is under two years.

The approach is simple – replace water in hydronic systems with a fluid that has superior heat transfer properties. Not only does the heating or cooling system reach the desired temperature more quickly (therefore, using less energy), but cycling is reduced, offering the potential of increased equipment lifespan and lower maintenance requirements. It’s a win-win situation and can even negate the need for new plant if increased heating/cooling is required.

In many ways, it’s an obvious solution to make commercial heating and cooling systems (and even water-based solar panel systems) work more efficiently. However, applying fluid technology to this area has been largely overlooked until now, and it’s challenging clients, specifiers and contractors to reconsider a fundamental element of HVAC systems.

glass, aerospace to medicine and even school uniforms.

Their use isn’t new within heating applications, but scientific advancements mean these tiny particles are now delivering substantial environmental and cost-saving advantages.

Sound scientific principles support their use, and worldwide installations demonstrate results.

The approach is compatible with most HVAC systems, and no major plant or system changes are required. The nano-tech fluid itself is non invasive, inert, recyclable and guaranteed for 20 years. Depending upon the application and system characteristics, it will normally deliver energy, carbon and cost savings of between 20 to 35%.

Installation There are two key elements to installation – assessing system volume and ensuring it is clean (which usually means flushing to remove sludge and inhibitors. This process can also help ascertain volume, if unknown) and in good condition with no leaks. Remedial work – for example, installing thermostatic radiator valves where appropriate – should be carried out prior to installation to ensure increased heat output can be managed. It’s then simply a case of re-filling the system with a 50/50 mix of water and the nano-tech heat transfer fluid.

Boiler sequencing/thermostats will need adjusting accordingly post installation.

The hi-tech nano-fluid is suitable for almost any building utilising a hydronic heating or cooling system – so data centres, hospitals, schools, accommodation blocks, public buildings, care homes, swimming pools, even ice rinks, commercial greenhouses and social housing. It is a warranted direct replacement for water and inhibitor.

How it works The fluid replacing water in HVAC systems in the UK (and globally) is a cutting-edge heat transfer solution harnessing the power of nano-technology to improve thermal conductivity. It’s an accepted scientific principle that material properties change as size approaches the atomic scale, with surface-area-tovolume ratio increasing. A cup of nanoparticles offers roughly the same surface area as almost two football pitches, and increased surface area equals increased heat transfer capability.

Nanoparticles are already an established technology delivering benefits in a variety of fields, from paints to FC& A – FEBRUARY – 2024

Projects The nano-technology has been utilised in more than 30 buildings for one UK organisation committed to net zero, starting with a pilot project of five properties. Of these, three recorded before and after energy usage, revealing gas consumption savings of between 37.5 and 47% from November 2022 to January 2023 when compared to the previous year (with an HDD – Heating Degree Day – calculation applied). ROI ranged from 1.42 years to 2.18 years. It should be noted that the buildings had TRVs fitted (some post installation of the nano-tech heat transfer fluid because occupants were complaining of being too hot), and the organisation demonstrated a significant focus on energy saving, leading to these

outstanding results. Feedback included comments that one of the buildings “felt hot rather than lukewarm” and that comfortable heating levels were achieved in areas that had previously been hard to keep warm. Reduction in carbon emissions is estimated to be around seven tonnes per site.

The Empire State Building in New York was an early adopter of the technology and is in the process of converting more of its hydronic systems to nano-tech heat transfer fluid. In addition, the Empire State Realty Trust has installed it into cooling circuits; two years ago, as part of an extensive upgrade, the trust installed it in an 11,000-gallon primary chill-out loop in a 25-storey office building that has two 350-ton electric chillers.

25

Tim Dailey, Director of Engineering for the Empire State Building, said: “We used to run both full out on a hot day, but now we never need to run the second chiller.

The chillers are much more efficient machines, and the electrical use of the central plant is basically half what it was.

Pumping is down, chillers are down, and a chiller reaches its sub point faster.”

In California, the technology has improved the efficiency of hydronic solar panels, with a test project at California State University showing ‘nearimmediate efficiency gains’ when the loop was switched to a nano-tech heat transfer fluid. A university spokesman said: “From the data, it looked like we were getting an increase in productivity when we switched the fluids. While running on glycol, the capacity of each solar panel maxed out at around 105 Btu. With Hydromx (the nano-tech fluid), the capacity of the panels increased immediately to 120 Btu.”

Conclusion The addition of nano-tech heat transfer fluid to HVAC systems speaks to netzero strategies, decarbonisation targets, legislative drivers, reputational benefits, CSR ambitions, fuel poverty and the overall management of energy bills. The approach is also suitable for geothermal, solar and heat recovery applications and perhaps more that we have yet to identify. Compared to many energy/ carbon-saving initiatives, it is relatively straightforward and offers substantial savings with attractive ROI rates.

DON’T GET LOST IN THE FOG: WHY FOG MANAGEMENT SHOULD BE A HIGH PRIORITY FOR COMMERCIAL BUILDING DESIGN Systems for managing fats, oils and grease (FOG) must be considered for the design of commercial buildings that contain commercial kitchens. The location, type and capacity of the system need to be taken into account, along with several other factors. Here, Erik Mul, Technical Product Manager from ACO’s Building Drainage division, discusses FOG management for commercial buildings.

ACO BUILDING DRAINAGE

T

he build up of FOG in the sewer is a considerable problem for buildings that contain commercial kitchens and UK water companies. We still see headlines referring to fatbergs even though legislation is in place intended to prevent these enormous blockages. In extreme situations, fatbergs have been known to reach as much as 400 tonnes in weight – approximately the mass of four blue whales. These are made of waste products that have been incorrectly disposed of in drains or down sinks, that bind together in the sewer, eventually becoming solid, dangerous to surrounding infrastructure and extremely difficult to shift. It is FOG that holds fatbergs together, showing just how important it is to have correct systems in place to handle the disposal of these kitchen cooking by-products.

Without suitable disposal methods, sewers can get backed up into homes and businesses, sewage and wastewater can cause flooding, and those responsible for the blockages can be held financially liable.

Water companies are enforcing rules more than in the past due to growing environmental concerns. They are also being stricter about prosecuting those who don’t meet legal standards. Due to these reasons, some new-build commercial projects are being denied a FC& A – FEBRUARY – 2024

water connection until a FOG management system is in place. In some cases, restaurants and pubs have faced significant fines due to their lack of proper FOG management.

Selecting a system There are four main types of management systems to be aware of when it comes to dealing with FOG. These include grease separators, grease traps, grease recovery units (GRU) and biochemical direct dosing units. Grease traps, GRUs and separators make use of gravity to separate FOG, enabling it to be retrieved for disposal or use elsewhere, such as biofuel. The bio-chemical dosing systems partially emulsify greasy wastewater, allowing it to pass through the system. While each approach has its merits, some systems are more appropriate than others, depending on a number of factors impacting the kitchen it will be used in. The most effective system will be one that is selected specifically for the individual building and its kitchens.

Grease separators are most commonly used in large commercial buildings. They comply with BS EN 1825 and prevent most FOG deposits from entering sewer systems and have to be emptied 26

KBB

lifting station where the separated wastewater is gathered or a sump where all the building’s wastewater is collected before pumping it out to the sewer.

In situations like this, ACO generally recommends the use of lifting stations in non-residential buildings rather than backflow preventers, as this ensures wastewater is still pumped to the sewer during a backflow event. In smaller establishments, it is unlikely that large units will fit within the kitchen, so external or smaller units would need to be considered – not forgetting maintenance access.

Some water companies are becoming firmer with their rulings and refusing to connect establishments that do not have proper FOG management systems in place. To avoid this, consulting with drainage experts from the early design stages will ensure all requirements and legislation are met.

Reasons for the regulations The goal of FOG-related legislation is to protect public sewers as they are a vital part of infrastructure. Section 111 of the Water Industry Act 1991 states that it is an offence to impair any public sewer’s operation. With the build up of FOG considered a hazard likely to impair a sewer, it is an offence for commercial kitchens to discharge FOG improperly. Local authorities or water companies may take legal action, those responsible can face prosecution, and the businesses might end up paying the costs for damage caused, including any cases where a FOG blockage causes flooding.

There are also laws in place geared towards preventing pollution from FOG. According to the Environmental Protection Act (EPA) 1990, it is illegal to dispose of FOG in a manner likely to cause pollution of the environment or harm to human health. Commercial kitchens have the legal responsibility to ensure the collection and disposal of FOG or risk prosecution.

Grease separator at least once per month – either manually or automatically, depending on the model installed. Choosing these units is done by looking at the following: number of meals per day produced in the kitchens, kitchen operating hours and the space internally or externally to site a separator. How the unit will be emptied – manually or via vacuum tanker – is also an important factor, along with the access needed for installation, commissioning and maintenance (considering if the ideal site is in the basement down lots of narrow corridors or underground in a car park, etc.). Smaller kitchens may use a grease trap fitted underneath a sink where they cater for lower volumes of meals per day.

Grease recovery units come in two types: active and passive.

Active units skim FOG using rotating oleophilic drums, whereas passive units use wastewater flow/pressure within the unit to move FOG into a separate container. The passive units are often heated to keep the FOG in a liquid state for easier disposal. Generally, these systems are tested to the American standard ASME 112.14.3 and 4.

There are also two kinds of bio-chemical dosing for FOG management. One uses enzymes to emulsify FOG and water prior to it entering a sewer, and the other uses bacteria to consume the FOG and release water and carbon dioxide. The microorganisms used in these systems are highly sensitive to their surroundings and don’t always survive long enough to be effective. In cases where FOG had been emulsified, it can still resolidify and lead to blockages further down the line.

Haven’t got the FOGgiest?

Speak to the experts The right management and disposal of FOG is a vital part of protecting the environment from pollution, keeping fatbergs from damaging sewers, and helping kitchens run safely and smoothly without risks of prosecution and punishment. While there may be some who think that FOG management is unglamorous, it is still extremely important to the long-term running of commercial kitchens, whether that be a small cafe or a large hotel restaurant serving several hundred people every day.

FOG management should be discussed early in the design of commercial kitchens along with consultation by experts, such as those at ACO Building Drainage. With their knowledge and experience, the process of identifying the right type of system for the kitchen can be done with the confidence that it will meet all relevant guidelines and regulations.

For more on fats, oils and grease management, visit the website below.

Pride of placement Due to the need for ongoing maintenance, access to the FOG management system must be factored in at the design stage.

BUILDING SAFETY ACT

BUILDING SAFETY: AN OPPORTUNITY FOR TRANSFORMATION Nigel Morrey, Technical Director at Siniat, discusses how the industry can embrace the tools at its disposal to enhance building safety standards not only for today but for the future, too.

SINIAT

T

he introduction of the Building Safety Act means that the sector now requires a seismic shift in the way that it operates.

From the conceptualisation of a build right through to deconstruction, the safety of each individual building element – and how it will react as part of a system – must be given greater consideration than ever before. In order to restore confidence in the safety and standards of all buildings, there is also an enhanced need to produce, share and revisit construction data to make sure that all buildings are not only safe during the build phase but that they will remain safe for their entire lifecycle, too.

This means that professionals in all areas of the supply chain need to invest in, adopt and embrace digital tools. In recent years, digital uptake amongst industry professionals has begun to increase, and larger numbers of firms have been adopting digital methods of manufacturing for, designing and constructing buildings, thanks to the speed, agility, accuracy and sustainability benefits it can offer.

However, with the Building Safety Act now mandating a requirement for a Golden Thread of building information, it is critical that we utilise digital technology to increase building safety, too.

FC& A – FEBRUARY – 2024

The Golden Thread The Golden Thread is defined as a secure and digitally-accessible record of data that contains all information that may be required to keep both the building and its occupants safe, both now and in the future.

This means that it should encompass all product and system performance data, insight into how different elements will react with each other, warranties, maintenance and operational information.

In addition to this, it must also be accessible and easy to understand not only to industry professionals, but to building managers, operators and even residents later down the line.

This is, of course, no small feat, and one of the challenges we face is that the construction industry has a complex supply chain. This means that a number of parties need to input into the Golden Thread to eliminate any risk of gaps in data that could lead to the Building Safety Regulator rejecting project plans or designs. To do this, a level of collaboration across all parties will be required to make the provision of data as simple as possible while ensuring that the format is standardised, easy to access and usable to those who will require it in the future.

28

An added complexity, however, is that there is currently no existing template or example for how this data should be developed or shared.

While some key trade associations are currently developing an outline for how the Golden Thread should be formatted and provided, we cannot afford to sit back and wait. Starting today, we must consider all tools at our disposal to ensure that data is being collated, shared and presented in a usable format.

The adoption and utilisation of digital platforms and mobile devices will make a significant difference when it comes to collating and sharing data with ease.

Digital platforms that can be accessed by all partners in real time will enable the principal designer or main contractor to collate the data required for a project and pass it on to the client without having to search through specification packs, revisions and any additional detailing – all of which are often updated throughout the construction process and are, therefore, at risk of being out of date by project completion.

A digital roadmap Digital platforms are not new to the industry and, in line with the enhanced requirement for high-quality product information, usage of this type of system has already increased. For example, NBS developed its innovative cloud-based specification system, NBS Chorus, back in 2018, which has been widely adopted by designers and suppliers across the industry.

BUILDING SAFETY ACT

However, the provision of data is not a requirement for one specific profession – or person – it is critical that every party on every project provides the data required to ensure that a building remains safe. So, while digital platforms have historically been a tool for designers or a ‘nice to have’ for others in the supply chain, they must now play a fundamental role in our everyday work.

This means that it isn’t just architects and specifiers who should be championing such tools – manufacturers, suppliers, subcontractors, developers and main contractors should also be utilising cloud-based, real-time systems to ensure the provision of accurate and upto-date performance data.

This data is critical for every element of a building, but drylining requires additional attention. This is because drylining makes up a large percentage of a building’s passive fire protection and, while we are all familiar with fire doors, fire glass and fire escapes, there is rarely mention of any such thing as a ‘fire wall’. However, to ensure our buildings are truly safe, it is critical that the fire performance of walls and finishings is also scrutinised and certified robust.

At Siniat, we know that adequate performance data and extensive testing of drylining systems are fundamental in ensuring safer construction. Therefore, to support our partners in meeting the requirements of the Building Safety Act, we recently launched our own digital platform, MySiniat. The platform grants our partners real-time access to CAD files, fire classification reports,

acoustic reports and datasheets to enable a smooth specification process while ensuring the provision of a Golden Thread of information that can be accessed for any project, from anywhere, at any time.

Driving competence While technology is a critical tool for ensuring building safety, it is not the only tool at our disposal. One of the most effective tools we have is our people.

By educating each other, listening to challenges and sourcing solutions to common issues, we will be able to actively increase competencies and ensure that we have safety ‘champions’ at every stage of the supply chain.

If we channel our efforts into ensuring that every contributor to the construction process is both educated and accountable, with the correct tools at their disposal, there is no doubt that the safety of our buildings will improve in tandem.

In recent years, we have invested in training not only for our internal teams but for our partners, too. This has enabled our technical team to share knowledge on fire performance with the wider supply chain to help drive competence on a larger scale.

The training has been underpinned by our significant investment into the testing and acquisition of third-party classification reports for our entire portfolio of systems, which are now provided as standard as part of our project packs both to educate our partners and support them in the sharing of critical data.

29

Of course, while additional legislation, new gateways and an enhanced requirement for product data have led to increased concerns around liability, we should – in reality – see the changing tide of construction as an opportunity for improvement.

Now is the time for us to build momentum around the tools and the skills we have at our disposal, instil best practice for future generations and heighten standards not just today but for tomorrow, too.

SAFER CITIES

ILLUMINATING EQUALITY: PUBLIC LIGHTING’S IMPACT ON SAFETY AND GENDER EQUALITY

Furthermore, the after-dark environment is rarely considered in any urban planning process. Often forgotten, it is one of the main items addressed by women and girls when speaking about perception of safety and after-dark atmosphere. In delving into the discourse on gender inclusion in urban design and planning, it becomes evident that acknowledging and rectifying these oversights are pivotal steps toward fostering truly equitable and welcoming urban spaces for all.

Elettra Bordonaro, Principal and Creative Director at Light Follows Behaviour and Senior Research Fellow at the London School of Economics and Political Science (LSE), joins forces with Marina Milosev (BEng MLA) Planning Policy & Gender Specialist. Together, they delve into the oftenoverlooked realm of urban design, shedding light on the impact of public lighting on safety and gender equality.

Gender-neutral urban design The influence of a ‘gender-neutral’ approach to urban design has compounded gender inequalities. Probably the most obvious and best-documented issue specifically faced by women and girls in public spaces is the perception of safety. The UN survey found that 36% of women felt unsafe walking in their local area at night in the UK, compared to 13% of men, and that 71% of all women in the UK have experienced sexual harassment in public spaces. It is part of everyone’s experience, the perception of not feeling safe and acting consequently, changing paths from daytime to nighttime, wearing hoods and male clothing to avoid attracting attention, walking closer to open/lit shops or where there are more passers-by and avoiding specific shortcuts through parks and darker alleys. These avoidance strategies not only impact their personal wellbeing but also hinder their involvement in crucial aspects of life, such as work, education and social activities. As a result, this prevents them from fully benefiting from the investments and opportunities that accompany urban development. In simpler terms, the oversight of women’s perspectives in city planning directly limits their access to benefits, and this is a double-sided effect, as, in turn, it also hurts the city’s economy. Addressing this issue is not just about making spaces safer; it’s about dismantling barriers that hinder women from progressing towards equality. UN Women has estimated that it will take another 286 years to reach gender equality in public life, which is unacceptable. Therefore, it is the responsibility of all actors, including the built environment sector, to assume its share of responsibility.

LIGHT FOLLOWS BEHAVIOUR

Gender disparities in urban design Traditionally, the realm of urban design and planning has overlooked the nuanced needs of women and girls, failing to embrace the intersectionality crucial to creating inclusive public spaces. Data, in fact, reveals that cities, rather than serving as equitable environments, have unintentionally perpetuated traditional gender roles and the division of labour.

Consequently, the design of cities typically caters more seamlessly to the preferences and lifestyles of heterosexual, able-bodied, cisgender men, leaving women and individuals with protected characteristics navigating spaces designed without their loved experiences, needs and aspirations in mind.

The twilight oversight An often-neglected dimension within urban planning is the consideration of the after-dark environment. While meticulously crafting cityscapes, professionals frequently omit the significance of night-time dynamics. Strikingly, this oversight emerges as a prominent concern for women and girls, particularly when discussing feelings of safety and the overall atmosphere after sunset.

SAFER CITIES

The importance of collaboration To achieve this ambitious goal, a collaborative effort is required, involving individuals with expertise not only in lighting design but also in social science, urban planning, architecture, landscape architecture, public engagement and diversity and inclusion. Their collective task is to produce a perception study report that delves into the intricate relationship between public lighting and lived experiences, placing a particular focus on the experiences of gender and vulnerable individuals.

Combining quantitative measurements with community and stakeholder engagement, this multifaceted methodology aims to gather a comprehensive understanding of how public lighting influences perceptions of safety after dark and to inform recommendations for an inclusive after-dark lighting strategy.

Beyond the glow At the same time, it is good to remember lighting cannot solve everything. Lighting is sometimes considered a utopic cure for all issues regarding public space. But it could as well be a placebo more than a real cure.

In fact, while public lighting is universally recognised as a critical factor influencing subjective perceptions of safety after dark, gaps persist in understanding the optimal quality of light and its impact on people’s experiences of the space. Additionally, the interplay between lighting and environmental factors, such as topography, vegetation and surrounding land uses, requires further exploration.

Lighting in itself can only augment the perception of safety if designed in collaboration with all other disciplines and based on a deep social understanding of the site.

Limitations of public lighting

Obstacles in public spaces Beyond safety concerns, women and girls encounter various obstacles in public spaces, public services, infrastructure and transportation, where their needs are often severely overlooked; lighting is inappropriately designed, or a leftover element; urban spaces fail to celebrate women through monuments, artwork and road names; plus, toilets and sanitation facilities are frequently inadequate.

Repeated research into the gender-sensitive design of public spaces underscores the significant impact of public lighting on the perception of safety, especially for women, girls and individuals with protected characteristics. If there’s one change we need to make to alter the landscape, it is to urgently reconsider our approach to lighting. Therefore, there is a need for a different lighting approach if we want lighting and safety to be considered throughout the design process.

31

Crude lighting recommendations that can be applied and ‘copied and pasted’ to any space should be avoided as they could actually be counterproductive and generate the opposite effect. For example, very bright lighting in social housing estates could act as a deterrent for people to cross by as, in terms of perception, it could lead to thoughts of policing and control versus valuing a possible social spaces.

Often, the perception of unsafety in public space is linked to a sudden change of atmosphere in the urban context, from a lit high street with plenty of retailers to a back alley or a social housing courtyard, a common experience in any UK city. It could be linked to poor visibility or neglected space. Poor maintenance, in general, could also play a big role in terms of perception, as safety is often related to the feeling of care of a space.

One of the most obvious examples, but not less interesting, is the idea that darkness is an element of unsafety. “it is too dark” and “It is not bright enough” are the first comments during engagement sessions about lighting. On the contrary, darkness could be synonymous with a luxury environment where bright lights are not needed as ‘you can afford darkness’ (see historical streets lit just by gas lighting versus floodlit spaces in the suburbs).

Shining a path to equality Light, therefore, represents itself an opportunity to address issues of urban inequality. It can be used to focus value, care and creativity on public spaces, estates and future mixed-use housing and can help build social inclusion and civic life across urban spaces.

REFURB & RETROFIT

The impact of interior aesthetics and comfort on customer experience is often the driving force behind refurbishment projects led by architects and building specifiers. Wall coverings, doors and surfaces play a key role in delivering the intended aesthetic but, with so many engineered surfaces to choose from, how can specifiers assess suitability for the project?

SCRATCHING BENEATH THE SURFACE: THE DEFINITIVE GUIDE TO CHOOSING THE MOST SUITABLE ENGINEERED SURFACE FOR YOUR NEXT REFURBISHMENT PROJECT

GEORGE EMMS,

SPECIFICATION SALES LEADER AT POLYREY, PART OF WILSONART UK, HAS OVER 20 YEARS’ EXPERIENCE IN THE ENGINEERED SURFACES SECTOR. IN HIS CURRENT ROLE, HE LEADS THE SPECIFICATION

George Emms explains the different types of surfaces available, some of the optimum use cases for each and the importance of compliance with key UK and EU standards.

POLYREY

Navigating the surface scene When it comes to refurbishments and new projects, surfaces can be a minefield for architects faced with so many different options. The need for speed, ease of maintenance and installation, and desire for full design flexibility have led to engineered surfaces becoming the material of choice for many stakeholders.

But, with so many options to choose from and important industry regulations to be met, it can be hard to navigate the vast number of choices available.

From wall coverings to doors and worktops, each individual surface plays a significant part in the overall aesthetic of a building’s ambience or decor, not to mention its durability and ease of maintenance. The importance of correct specification is imperative when it comes to major refurbs, with little room for remedial work or error. To assess which engineered FC& A – FEBRUARY – 2024

surface is right for your project, the specific demands of the environment must be considered. Once these have been clarified, the chosen surface needs to be up to date with the key UK and EU regulations and standards for use in specific settings.

Which surfaces can I choose from?

Choosing the right surface for any given application is key, not least because getting it right the first time avoids disappointing customers, incurring costs and disenfranchising installation teams.

Choosing the right surface isn’t just about the look and feel; it’s also about longevity, durability, compliance and maintenance. The engineered surface choices available are suitable and adaptable solutions for many industries, going beyond just a potential alternative to more traditional materials.

For example, for a high-traffic application like a reception desk, options include melamine-faced boards (MFB), high-pressure laminate (HPL) bonded to a substrate or compact laminate. MFB may be a stylish, costeffective and quick-to-source and -fit product, but its low-pressure manufacturing process, which typically sees one sheet of paper fixed to a choice of substrate, generally means it struggles to stand up to the rigours of frequent use. HPL-bonded boards, however, use a high-pressure process that combines the decorative paper with six sheets of kraft paper and a protective overlay, which results in a higher surface performance. In turn, this will also, in some instances, feature an antibacterial coating – perfect for food prep areas or regularly-used surfaces in health and hygiene-conscious markets.

BUILD FOCUS: REFURB & RETROFIT

Compact laminate is another alternative, the ultimate in hard-wearing solutions. Boasting increased impact resistance compared to HPL-bonded boards, plus the sort of premium finish capable of creating a cohesive and stylish decor from room to room, compact laminate tends to be a popular choice for customer-facing spaces where there’s an opportunity to wow visitors.

Due to its solid compact core, compact laminate does not require edging, saving labour and removing any potential damage caused by high-traffic areas.

Other examples include considering vanity tops for bathrooms; HPL-bonded boards could be a good option here.

However, usage considerations are important. Whilst this would be the most cost-effective option, it is important to be aware that any water ingress could render the vanity unusable in a few years. Quartz is another option, offering a surface solution but at a considerably higher cost. Compact laminate would be the recommendation – hard wearing and waterproof, perfect for this scenario, without the costly templating associated with quartz.

With an almost endless list of possible surface types for various situations, navigating the surface scene can, at first glance, seem complex, which is why experts, such as the Polyrey technical and sales support teams, offer assistance with surface specification.

Which standards do I need to ensure compliance with?

In the first instance, once a surface has been selected, it is imperative that standards and regulations are complied with. In some instances, this will be a case of best practice, while others will be mandatory. Getting to know the applicable standards and regulations is, therefore, a crucial part of understanding which engineered surface will be the best to specify.

Ultimately, with commercial buildings within the hospitality sector requiring such a wide variety of amenities, surfaces, settings and furnishings, the list of potential regulatory requirements will often be vast, so it is always worth checking which specific requirements are in play for a given project.

initial inspection of the manufacturing premises followed by periodic reinspections. This product testing standard is accredited by the UK Accreditation Service (UKAS).

With that said, some of the most frequently encountered regulations include:

UL Greenguard certification Greenguard certification indicates that a product has been tested and certified to meet stringent emissions standards for over 360 volatile organic compounds (VOCs) and chemical emissions. The highest standard of HPL panels is Greenguard Gold rated. All Polyrey HPL panels and compact highpressure laminate worktops are A rated in this category.

Furniture Industry Research Association (FIRA) standards The FIRA Gold standard includes assessment and testing of: structural performance; safety and stability; ergonomics; finish performance; the effects of moisture, humidity and temperature; flammability; workmanship; even the quality of assembly instructions and installation procedures; plus an

BREEAM (Building Research Establishment Environmental Assessment Method) Common across many other product categories, this is the leading built environment sustainability assessment method, undertaken by independent licensed assessors using scientificallybased metrics and indices covering a range of environmental issues.

33

Building Regulations It is extremely important that European Building Regulations are comprehensively understood by industry professionals to ensure safety standards are complied with.

As specific requirements vary between different surface types, a thorough and broad understanding is essential.

The perfect fit Having the knowledge of standards and product specifications makes the decision process easier. Whether concerning surfaces to adorn doors or walls, choosing a supplier that can help navigate regulations and standards is vital. Access to a suite of products that can match the decor and meet multiple criteria for a coordinated approach.

TECH INSIGHT: WATERPROOFING

THE ROLE OF SINGLE-PLY MEMBRANES IN SUSTAINABLE CONSTRUCTION Carl Bailey, Regional Technical Manager for Elevate, part of the Holcim Group, explains how single-ply waterproofing can help make a building more environmentally sustainable.

ELEVATE

T

Reducing environmental impact

he construction industry has a vital role to play in responding to the climate crisis. In the UK alone, 25% of carbon emissions are directly attributed to the built environment. To meet net-zero targets, the need to reduce buildings’ operational and embodied carbon is more pressing than ever.

Roofing design plays a key role in sustainable construction.

Adopting a fabric-first approach, which prioritises the building envelope in the early design stages, will result in a more energy-efficient property and enhanced thermal performance.

The materials used in a roofing system can also have a significant impact on the property’s lifespan, maintenance, waste and recyclability.

The waterproofing layer is a crucial component of a sustainable roofing system. Single-ply membranes, which are made from a synthetic polymer-based material, provide waterproofing in a single sheet. Usually supplied in rolls, the material is either entirely homogeneous or contains a reinforcement layer. The membranes are sealed at the joints using heat, adhesive or mechanical fixings.

The main types of single-ply membranes in the UK are EPDM (ethylene propylene diene monomer), PVC (polyvinyl chloride), TPO (thermoplastic polyolefin) and PIB (polyisobutylene). All are compatible with green and blue roofs as well as solar panels. A chemically-inert material, EPDM has a low environmental impact and does not contain any plasticiser.

Most popular in Europe, PVC membranes are hot air or solvent welded and can be supplied in a variety of colours. Plasticisers provide the membrane’s flexibility, but from an environmental perspective, the material’s green credentials are increased thanks to its durability. TPO combines the hot air weldability of PVC membranes but is free from plasticisers and highly reflective.

First used in the 1950s, PIB is the oldest of the single-ply membranes and has no significant environmental impact. Thanks to the improved formulation of single-ply membranes, the release of carbon during operational use has been almost eliminated.

The product’s longevity has increased, too. The absence of plasticisers allows the membrane to retain its flexibility without the risk of migration, which can lead to cracking, flaking and, ultimately, the failure of the roof surface. Single-ply membranes are BBA certified for up to 30 years or more. EPDM and PIB have the longest life expectancy, with many third-party assessments indicating 50 years and beyond.

A further sustainability benefit is recyclability. For refurbishment projects, it is estimated that up to 80% of single-ply membranes can remain in place as an underlay. If the roof does require stripping, it is possible to recycle the old single ply, although the level of recyclability will vary depending on which type of membrane is selected.

Flat roof design considerations There are three types of flat roof structures, including a cold, warm and inverted roof. A cold roof is designed with the insulation below the structural deck and requires ventilation openings to avoid damp and condensation. However, the updated BS 6229:2018 code of practice does not recommend a cold roof design, and in some UK regions, it will not be approved by building control.

A warm roof is the recommended and most technically-sound design for flat roofs and sees the insulation placed above the roof deck and beneath the membrane. Eliminating cold bridging, this build up is thermally efficient and can prevent condensation through the installation of an Air and Vapour Control Layer (AVCL).

Suitable for green and blue roofs as well as trafficked areas such as terraces, an inverted roof system does not require an AVCL. The waterproofing layer sits beneath the thermal insulation, which should have a high resistance to water and a density that can support the footfall. A deep roof zone will need to be accommodated as part of the design to ensure the structure can support the load. Gravel or paving slabs are usually used to ballast the roof covering to secure against wind uplift and other damage.

The sustainability of a flat roof can be enhanced in various ways, including through a green or blue roof design as well as the installation of solar panels. These enhancements will, however, affect the choice of membrane and installation. For example, when specifying a single-ply membrane for a green roof, it must be tested in accordance with FLL guidelines, ensuring it is root and rhizome resistant.

As far as solar panels are concerned, these can either be mechanically fixed through the waterproofing membrane or weighed down with ballast. Where a roof structure can take the load, non-penetrating attachment systems are recommended if possible. For refurbishment projects, specifiers should also consider the manufacturer’s guarantee, which could be invalidated by breaching the waterproofing.

Engineered roofing systems, which use ballast, will secure waterproofing without relying on adhesives or penetrations through the membrane, making them much simpler to install.

TPO Educational and Recreational Centre. ©Holcim Solutions and Products

What to expect from manufacturers When selecting a single-ply waterproofing membrane for a sustainable roof, specifiers should receive comprehensive technical support from a manufacturer, including NBS specifications, a cutto-falls insulation design, wind load and thermal calculations and confirmation of a third-party accreditation such as BBA. A manufacturer’s technical advice in a project’s early stages should also ensure the most appropriate roofing system is developed and the membrane is applied in accordance with their guidelines. Once the system is approved by the technical services team and executed by a trained, licensed contractor, a long-term warranty can be provided for peace of mind.

Water behind render of external leaf

ACCEPTABLE PROPERTY DETERIORATION How waterproof is a rendered wall? Does the photograph taken of a property constructed just 15 years ago suggest water penetration and deterioration may be higher than foreseen, and the subsequent life expectancy of the rendered walls not as lengthy as envisaged?

CAVITY TRAYS

T

his multi-occupancy building has blockwork cavity walls with an external rendered finish. The finish was originally pristine, but the photograph, taken most recently in December 2023, shows to what extent the external walls have now deteriorated.

Regardless of whether a traditional or a proprietary render has been used, what is apparent is the deterioration to date, which suggests replacement rendering will be required in the foreseeable future.

Dampness, cracking and spalling are evident at damp course levels within the parapet walls, horizontal intersections, above openings and at cavity barrier levels.

Fissures feature within most rendered areas. Rain is penetrating the rendered external envelope.

Penetration is unlikely to be solely through the render coat, as other areas, such as parapet copings, jointed sills, verges and opening surrounds of a different finish, can all provide entry routes.

Commonly, BBA certificates for building materials refer to a performance period of 60 years, but some BBA certificates for rendering quote a figure of just 25 or 30 years. The question arises of whether the deterioration witnessed is in line with, or below, the anticipated projected performance, regardless of render origin – proprietary or traditional. To what extent have other factors contributed to the current condition? The type and composition of the external leaf, the preparation, structural movement, weather conditions during construction and quality of application are all influencing factors.

Throughout the life of a typical rendered building, there is a common denominator. No render will be totally impermeable. Rain will penetrate the external skin of a cavity wall, and it requires an exit path. Water retention because of an absence of weeps can result in water being trapped within a cavity wall at DPC levels – retained in the external skin behind the render coat. Rain will get in – constructing so it can get out makes sense.

Within a rendered surface, the careful choice of weep can promote maximum outflow but with minimum visual presence.

The beak weep provides minimal elevation interruption. With a full-height cavity aperture and a discreet elevation beak offering protection against wind-driven rains, the beak weep can be used in areas that are highly exposed.

The beak weep has no pinch-point impingement along its internal flow route (unlike some). Its protected outlet addresses the major concern of water retention (wind pressure preventing evacuation) and water volume being trapped and overwhelming the DPC/tray system within the wall.

Importantly, the drop outlet is dimensioned with upward radiused sides to permit washed mortar sands to spread and drop at the outlet, an advantage not available with alternatives.

Incorporating beak weeps cannot banish every problem, but as part of a Cavity Trays’ elevation appraisal embracing tray and water evacuation disciplines, they can help prevent many of them from manifesting in the first place.

Cavity Trays is the longest-established company within its specialised field and recently celebrated 100 years of external envelope problem solving.

HOW BIM TECHNOLOGY IS TRANSFORMING ARCHITECTURE AND CONSTRUCTION: A PRACTICAL INSIGHT In a world of architecture and construction guided by constant creativity, the reinvention of standards and the emphasis on sustainability, one question prevails – what impact will the digital transformation have on the way houses and buildings will be designed in the future? In view of the threat of human labour being replaced by automated means, these industries are currently dictating the value of a complementary relationship between technological and human capabilities.

VICAIMA

Combining the potential of technological and conventional tools

mong countless possibilities, the BIM (Building Information Modelling) methodology emerges as one of the tools with the greatest capacity for developing the daily procedures of professionals, offering vast potential when it comes to increasing the efficiency of project planning and execution.

According to BIMobject, the largest BIM content platform in the world, the number of professionals joining this programme tripled between 2017 and 2021, totalling more than 3.5 million users in 2022. Users of this tool are growing by leaps and bounds in the face of an innovative digital transformation, providing companies with a competitive advantage that boosts new business opportunities, although challenges remain in the everyday usage of the methodology.

In a universe of possibilities, Vicaima, one of the pioneers in the launch of BIM objects for interior doors, shares the key practical guidelines for the effective implementation of this technology in a construction project.

In the daily environment, operating with BIM implies providing all the components of a building in a digital format. This process will only fulfil the desired results if the management and execution of a project incorporates both virtual and traditional tools. The ultimate integration of these two universes means bringing the advantages of digital to the practical domain. In this sense, all those involved in a project, regardless of their background, are able to communicate in a common language, enhanced by BIM.

Understanding and complying with BIM standards The management of a project using BIM, in addition to being carried out by an independent organisation, must be aligned with ISO standards. These international norms ensure compliance with the highest levels of quality and safety.

By relying on in-depth knowledge and strict respect for the essential principles of BIM, professionals gain continuous and up-to-date access to tools such as 3D modelling, energy calculations, budget control and certifications, among other capabilities.

The digitalisation process in the architecture and construction sectors is being revolutionised by BIM technology.

Numerous professionals agree that it is dramatically reshaping the way buildings are designed and constructed. Rigorous adherence to these principles is key for minimising errors, ensuring more efficient execution, reducing the risk of delays and preventing additional costs.

BIM is boosting the construction industry, making it possible to design more sustainable, comfortable and efficient buildings. By embracing this approach, we are moving towards a future where technology and human innovation come together to create environments that improve quality of life.

Using BIM technology consistently throughout the course of a project The coordinated use of BIM technology, whether between the design, construction or operation and maintenance stages, as well as between the various parties involved in each project, is one of the key factors in guaranteeing the successful application of this tool.

From the birth of a development and throughout its entire lifecycle, taking advantage of BIM can become even more valuable when carried out coherently at each phase, gathering vital information.

Vicaima acknowledges this relevance, streamlining the workflow of professionals by allowing 3D visualisation of its products as well as the management of their technical information. Vicaima Wardrobe solutions in BIM are available in different configuration options, including all the wardrobes with sliding doors in its Advanced Range, as well as its extensive range of Portaro solutions available with various performance options, models and finishes.

Interior product enhancements

ENDLESS COLOUR POSSIBILITIES FOR INTERIOR AND EXTERIOR WOOD Osmo is the specialist when it comes to an optimal interplay between wood and coating systems. Considered as high solid products in comparison to conventional coatings, Osmo coating systems are more environmentally friendly due to fewer solvents being emitted upon application while providing higher wood surface coverage and increased longevity and durability of the wood finish.

OSMO

F

rom the standard colour range and the nature-inspired Osmo Elements colour range to the well-known RAL, NCS and BS colour charts, the tinting system offers both trade and DIY enthusiasts a complete colour customisation for interior and exterior wood. This is only the beginning; Osmo will continue to expand the range of colour

and product offerings, providing an everincreasing array of vibrant choices.

The on-demand custom colourmixing service produces ready-to-use wood coatings for any customer within minutes, reducing order waiting times, wasted product stock and required retail store space.

Before the Osmo Tinting System, the most popular hard wax oil, Polyx-Oil Original, was available in only four clear finishes. Now, these four original finishes can be tinted in eight transparent colours.

So, what’s new? Previously, these eight transparent colours were only available in a satin finish.

The tinting system means that not only can these colours be mixed in all four finishes, but they can be mixed within minutes, too, for the first time ever.

Additionally, Polyx-Oil Rapid, which offers rapid drying times compared to Original, was previously available in only two clear finishes. Now, following suit, Rapid can also be mixed in the eight transparent interior colours with a satin or matte finish. Again, this is a first for the company and the world.

Finally, Wood Wax Finish joins the custom mixing interior range, offering a wide variety of transparent and opaque wood finishes in thousands of colours.

Exterior product enhancements Osmo has launched four of the most popular exterior wood finishes with the Osmo Tinting System, including the latest release of opaque colours by Country Shades, which boasts a huge 120 colours from the Osmo Elements colour range, plus thousands of colours from the RAL, NCS and BS colour charts.

Natural Oil Woodstain, which is suitable for all exterior wooden surfaces, has seen a big enhancement and can not only be mixed in all its 18 transparent finishes, in both a satin and a matte finish, but can now also benefit from the thousands of colours from the Elements, RAL, NCS and BS colour charts, too.

Ideal for vertical wooden surfaces, UV-Protection Oil can now be mixed in eight transparent colours in two satin finishes. For exterior wooden decking, Decking Oil can now be mixed on demand in 11 transparent colours in a satin finish.

Find your nearest Tinting System store on the Osmo website and contact the team for expert advice and wood-related knowledge. Give wood the clear and colour protection it deserves, both inside and out.

IRONCLAD BS 8629 COMPLIANCE FOR SHEFFIELD DEVELOPMENT

Fire protection solutions manufacturer, Advanced, has supplied its BS 8629-compliant EvacGo evacuation alert system to new-build residential development, The Ironworks, in Sheffield.

ADVANCED

n addition to the evacuation alert system, The Ironworks also benefits from robust fire protection of its landlord areas thanks to the installation of Advanced’s flagship MxPro 5 fire panel. Fire and security service provider WPS Fire & Security installed both systems and was involved in the project from the design stage through to commissioning.

The Ironworks forms part of the first wave of high-rise construction to be completed since evacuation alert systems became mandatory in new residential buildings over 18m in England and Wales in December 2022. The amendments to Approved Document B (Fire Safety) of the Building Regulations also stipulated that these systems adhere to BS 8629 – the code of practice outlining how evacuation alert systems should be designed, installed, commissioned and maintained.

This should give residents in buildings, like The Ironworks, reassurance that if they need to leave the building in a fire, the instruction will be communicated clearly and safely.

Each EvacGo panel is housed inside a STS 205 security-rated enclosure with a patented BS EN 1303-compliant lock and key mechanism for exclusive access by the fire and rescue service – ensuring minimal risk of unauthorised use and full compliance with BS 8629. At The Ironworks, the main panel is supported by a sub-panel, with one sounder in each of the 228 apartments to alert residents in an evacuation scenario.

ROCKWOOL DEVELOPS CPD TO PROMOTE FIRE SAFETY OF MULTIFUNCTIONAL ROOFS

LUCECO LIGHTS UP LUTTRELLSTOWN CASTLE

ROCKWOOL

LUCECO

ROCKWOOL, one of the UK’s leading stone-wool insulation manufacturers, has launched a new CPD module to help roofing contractors and specifiers assess and mitigate potential fire safety risks for flat roofs used as additional functional space of a building. This CPD aims to improve the understanding of the role of the modern flat roof, and how to identify and mitigate fire risks above and below the roof and is based on the recently-launched white paper ‘Flat roofs: The functional fifth façade’. Participants in the ‘Flat roofs: The functional fifth façade’ CPD will learn about the requirements of the Building Regulations for flat roofs and the role of guidance documents like Approved Document B, or regional equivalents. The final section of the CPD outlines ROCKWOOL’s range of fire-resistant stone-wool insulation products that are compatible with a variety of modern flat roof systems. The new module is available through the manufacturer’s bespoke learning platform, ROCKWOOL Learning, or as a traditional in-person course. To learn more about the CPD, and to register for a place, visit the website below.

Luttrellstown Castle Resort near Dublin is a luxurious venue for elegant hospitality and entertainment, combining the original 15th-century castle, 567 acres of parkland and a championship golf course with an alpine lodge-style clubhouse. With such multiple uses, outdoors and indoors, it is not surprising that the site has multiple needs in terms of lighting. Luceco worked directly with the facilities manager over a couple of days to map out specifications for the project. Luceco replaced all the interior lighting with LEDs, specified high-bay lighting for the castle’s lamps and chandeliers and the British General Evolve range of sockets and switches in matte black. The Evolve range was also used in the restaurant, while exterior lighting was upgraded to further improve aesthetics, with Kingfisher Bollards installed in the driveway and the golf course. More efficient LED panel lighting and emergency lighting were added around the golf course, while solar Guardian floodlights were installed on roofs, and Elara Bay fittings were installed in the greenkeeper’s shed.

BUILDING ELEMENTS

Deflection and natural frequency Tight deflection requirements and natural frequency had to be overcome, too, and the detailing was again calculated using Finite Element Software.

The contractor and design teams provided values for both long-term deflection and dead-load deflection only, which determined the amount of pre-camber required during construction. This was a challenging section to calculate due to the additional support factor of the raked end, which sits on a rigid wall.

Expansion and contraction issues

SCHÖCK CHOREOGRAPHS BESPOKE CANOPY AT SADLER’S WELLS EAST Enhanced by the saw-tooth roof design, reflecting the industrial heritage of the site, Sadler’s Wells East will join the cultural heritage of the East Bank development at Stratford when the new dance theatre opens at London’s Queen Elizabeth Olympic Park in 2024. The design has many distinctive features, but a major focal point is a cantilevered canopy. This runs the length of the frontage and is designed to carry a precast green roof – which presented several design and structural challenges.

SCHÖCK

A bespoke solution from Schöck The canopy is 51m long with very high support loadings, carried by the end profile of the in-situ RC cantilever beams – each 500mm wide x 950mm deep, with a cantilever of 4.6m. The span between the beams is 4.2m, with 12 beams along the canopy length. In the normal permanent condition,

the moment and shear loads were 900kNm and 360kN, respectively. Due to the complexity of the loads and arrangement of the bespoke Schöck Isokorb elements required to transfer such high forces into a relatively small concrete beam section, the support rods were designed using Finite Element Software.

The cantilever beams, aligned

with internal supporting beams, allow the Isokorb rods to penetrate far enough into the structure to distribute the demanding loads. In addition, it was necessary to consider bomb-blast loading, which introduced uplift forces. So, the design had to accommodate loads in both positive and negative directions for both moment and shear.

Totally verifiable performance

www.schoeck.com/en-gb/solutions FC& A – FEBRUARY – 2024

The length of the main canopy and the size of the rods required to transfer the main forces meant that thermal stresses would be caused by the expansion and contraction of the external concrete.

Expansion joints, therefore, had to be introduced at every third beam (approximately 8.4m centres), which carry the load from one set of precast canopy sections onto the supporting beam. Here, Schöck incorporated its new heavyduty Stacon shear force doweltype SLD. This new dowel is a uniquely compact product and, as the anchoring bodies have been reduced in size, it has the advantage of enabling higher loads to be installed in thinner slabs and walls, optimising onsite reinforcement.

The dependable and fullycompliant Schöck Isokorb range helps projects meet full compliance with the necessary UK Building Regulations. There are solutions for concrete-to concrete, concrete-to-steel, steel-to-steel, renovation projects – and even a maintenance-free alternative to wrapped parapets. All products have the security of independent BBA certification, which provides NHBC approval. Also, the new Stacon dowel has been awarded UK Technical Assessment (UKTA) along with fire protection classification R 120.
