We are delighted to feature EcoSync as our Intelligent Heating Control System Company of the Month

The majority of Smart heating systems now turn ‘on or off’ but imagine if you could heat just one room or specific zones remotely using smart devices? This would allow business establishments or educational facilities to save 20-50% on energy bills and reduce carbon footprint. It’s a win-win situation.

EcoSync is a pioneer in heating management for commercial buildings and multi-occupancy residences, thanks to its innovative Smart Thermostatic Radiator Valves (TRVs). With a growing portfolio to date, of over 42 customers and more than 140 buildings across the UK, EcoSync has been instrumental in saving more than 1.565 MWH of energy and slashing carbon emissions by over 285 tonnes.

These next-generational TRVs, free from the constraints of batteries and maintenance, offer seamless installation and operation, making them an ideal heating solution for commercial buildings looking to optimise energy use and reduce waste. EcoSync's technology directly addresses the significant issue of heating energy wastage in unoccupied rooms, which can account for up to 40% of energy consumption in such spaces. By enabling precise heating control on a roomby-room basis, EcoSync's TRVs ensure energy savings of 25-50% for clients, showcasing their effectiveness as a heating solution.

EcoSync caters to the specific needs of Facilities and Utilities Managers, Energy Managers, Public Sector organisations, and Senior Buyers in the commercial sector who are focused on achieving low carbon, Net Zero, and energy efficiency goals. The addition of an AI-powered dashboard, in-room QR codes, a carbon meter, and room booking system integration enriches EcoSync's offering, making it a comprehensive energy management and heating solution for commercial and multioccupancy buildings.

The benefits of adopting EcoSync's TRVs as a heating solution over traditional, batterydependent systems are clear. Conventional systems require ongoing maintenance and regular battery replacements, which can be particularly burdensome in large commercial or multi-occupancy buildings. EcoSync’s TRVs eliminate these challenges, boasting an installation time of under a minute and zero maintenance requirements.

EcoSync provides high-quality data for ESG reporting, analysing buildings and identifying areas with higher-than-average heat loss.

EcoSync provides a multi-award-winning Smart Temperature Control System from the great minds at Oxford University. Established in 2018 by two entrepreneurial academics: Dr Zsuzsa Mayer and Yoav Gross, EcoSync is an active member of UKGBC and the Energy Managers Association. For two consecutive years: 2022 and 2023, the team has won the prestigious Property Week Student Accommodation, as part of the Climate Crisis Initiative together with Corpus Christi College of Oxford.

Dr Zsuzsa has a Ph.D. in Renewable Fuels & Bioenergy from Aston University of Birmingham and Yoav has a Master’s in Environmental Change and Management from the University of Oxford. Using exceptional R&D, they have devised a system that can reduce heating-related carbon emissions and energy bills by up to 50%.

“The demand-side control doesn’t rely on sensors,

instead the patented technology inputs QR codes scanned by users when leaving a room empty. The controller is intrinsically part of an intelligent IoT device, negating the use of wires or batteries due to the built-in energy harvesting feature.

By using LoRaWAN: our commercial communication technology, the data is collected to create the digital twins of the buildings that can be used for metering (real-time consumption and savings) or running various models - how would the building and the individual rooms behave with a heat pump instead of a gas boiler etc.

rooms!

Furthermore, our 2nd generation is a plug-andplay technology that can be retrofitted by the client with minimal training requirements. It costs a fraction of the traditional building management systems (BMS) plus it can adapt to the dynamically changing occupancy levels,” explained founder and now Chief Innovation Officer: Dr Zsuzsa Mayer.

EcoSync has gone further than other Smart Temperature Control Systems: on top of AIpowered optimisation and control, it can collect data to support other building retrofitting projects such as monitoring the payback of installed doubleglazing. With the onus on the UK Government's 2050 net-zero targets, many businesses are looking to strengthen their Environmental, Social and Governance (ESG) policies.

“Going forward, we would like to support our clients not only with the energy efficiency improvement of their buildings but also with their next big challenge: decarbonising the grid, which mainly means replacing gas boilers with heat pumps. We would like to design a service that can provide data both at the planning stage and later for optimising the performance of their heat pumps.” explained Dr Zsuzsa.

Heat pumps are hugely energy-efficient as they produce more heat than they consume (supplementary) electricity and are rapidly becoming the cheapest, lowest carbon form of heating available. The UK Government has pledged to install 600,000 heat pumps by 2028, as part of the Energy Security Bill.

The UK is still playing catch-up with the rest of the EU, notably Norway, Sweden, Finland and Estonia for heat pump adoption rates but with reduced North Sea gas production, the UK is now urgently committed to futureproofing its energy security through renewable energy. Between 2021-2022 alone, the sale of heat pumps increased by 40% and the facts speak for themselves: more than 80% of global space and water heating demand could be met by using heat pumps instead of gas boilers, with significantly reduced carbon emissions. Buildings alone contribute to more than 40% of energy used, which equates to over a third of global emissions and with the real threat of climate change, reducing energy use and emissions is now a global priority.

“We are committed to meeting the real needs of climate change and fully understand that our clients need high quality data for their ESG reporting purposes and we can provide that. Moreover, it works in those commercial buildings where there is no budget for a BMS but data is needed for investment purposes.

“The launch day marked not just a milestone but served as a clarion call for the Commercial Real Estate sector to accelerate its journey towards Net Zero. The UKGBC's dedication to transforming the built environment through practical strategies, including optimisation, CAPEX-light, and significant investments in retrofitting, is truly inspiring. It's evident that the path to net zero is paved with innovation, collaboration, and actionable insights.

We are currently working extensively with boarding schools, higher education and PBSAs (purposebuilt student accommodation) providers, to provide our Smart Temperature Control System. This not only reduces energy bills in a cost-of-living crisis but wholeheartedly commits to ESOS compliance and substantially less carbon emissions, allowing companies to exercise sustainability best practices.” added Dr Zsuzsa.

EcoSync is helping businesses join the green agenda and was recently delighted to attend the Advancing Net Zero hosted by the UK Green Building Council (UKGBC) in March this year.

By focusing on low-cost, high-impact adaptive and intelligent retrofit solutions, we help buildings not just meet, but exceed their sustainability targets.” outlined Simon Brown, Partnership Director.

EcoSync is much more than a provider of smart heating solutions; it is a key stalwart in the path to a sustainable future for commercial buildings and multi-occupancy residences.

The presence of mercury in flat panel displays

The presence of mercury in flat panel displays (FPDs), such as laptop monitors and LCD TVs, has brought into focus prospective health and safety issues when considering the WRAP (The Waste Resources Action Programme) commissioned study into the technical and commercial potential for recycling the items.

The research, which was carried out by environmental consultancy Axion Consulting, aims to help WRAP identify viable recycling outlets. However, due to an increased uptake in items, WRAP anticipates that the number of FPDs in the WEEE waste stream will rise ‘dramatically’ (It is considered that there will over 145,000 tonnes of flat panel displays in the waste stream by 2018) in the next few years bringing pressure to automate suitable commercial recycling processes in the UK and Europe.

In particular the study looked at the presence of mercury in the cold compact fluorescent light in the ‘backlighting’ system for LCD TVs, laptop computers and desktop monitors. The existence of this mercury means that end-of-life FPDs are classed as hazardous waste.

Mercury is extremely toxic, with inhalation of the vapour producing harmful effects on the brain, nervous, digestive and immune systems, lungs and kidneys. Mercury poisoning can result in several diseases,

and duration of exposure.

Humans are mainly exposed by inhaling vapours. These are absorbed into the body via the lungs and move easily from the bloodstream into the brain. However, when elemental mercury is ingested, little is absorbed into the body.

The conclusion of the WRAP study highlighted that employees at an FPD recycling facility would be subjected to levels of mercury ‘higher than is acceptable’. However, it suggested that this could be reduced with personal

EV charging infrastructure review and supply of pre-wired EV distribution cabinets & feeder pillars

There is now real impetus for drivers to switch to cleaner vehicles, with the impending 2035 ban on the sale of new petrol or diesel car. There has been steady growth, with an estimated 1.02 million zero-emission electric vehicles (cars) on UK roads today, alongside 615,000 plug-in hybrids.

The number of public charging stations are growing too across workplaces, council-owned car parks, hotels and numerous other places, to keep up with demand.

One of the biggest questions remains though: How do you maintain reliable and ever-increasing charging speeds while keeping the users and installers safe, through adherence to BS7671:2018 amendment 2:2022?

The role of electrical distribution cabinets for EV chargers

Correctly designed and manufactured electrical distribution cabinets are an integral aspect of the EV charging infrastructure, providing optimised safety and reliable electrical connections for EV charging equipment. They are typically configured to provide automatic disconnection of the supply for a given fault condition such as a short circuit, overcurrent, earth fault, and open neutral conductor (O-PEN fault on the incoming supply side cable where PME is used).

Who is a trusted manufacturer/supplier of electrical distribution cabinets to power EV Chargers?

Hot water: The key to unlocking

The importance of launching a sustainable strategy for commercial buildings has never been more important. According to recent data from the EU’s climate service global warming has, for the first time, exceeded 1.5ºC across an entire year. This temperature limit, promised by world leaders in 2015, has been seen as crucial to help avoid the most damaging impacts of global warming. A 2018 UN report said that the risks from climate change – such as intense heatwaves, rising sea levels and loss of wildlife – were much higher at 2ºC of warming than at 1.5ºC.

Limiting long-term warming to 1.5ºC above pre-industrial levels has been a key symbol of international efforts to tackle climate change, and whilst the report notes that this first yearlong breach doesn’t break that landmark Paris Agreement, it does bring the world closer to doing so in the long-term.

All the major datasets agree on the recent warming trajectory and that the world is in by far its warmest period since modern records began –and likely for much longer. Berkeley Earth reported that the calendar year 2023 was more than 1.5ºC above pre-industrial levels. Other science bodies, such as NASA, put the past 12 months slightly below 1.5ºC of warming. Fluctuations in reporting are expected, but at the current rate of emissions, the Paris goal of limiting warming to 1.5ºC as a long-term average – rather than a single year –could be crossed within the next decade.

This new data sends out yet another clarion call to the commercial sector, where sustainability has

become a defining theme for modern businesses increasingly seeking ways to reduce their environmental impact. While numerous avenues exist, prioritising water heating in a commercial sustainability strategy offers unique advantages, making it the optimal starting point for many organisations.

So why is addressing water heating in commercial buildings so significant? And how can it serve as a springboard for launching a sustainable strategy to more broadly support commercial organisations?

Water heating often accounts for a significant portion of a building’s energy consumption, ranging from 15-40% depending on the industry and usage patterns. This makes hot water both familiar and more often than not business critical, so reducing hot water demand and implementing efficient heating methods translates to substantial energy savings and emission reductions that have recognisable advantages to its users across the built estate.

energy demands means initial investment is often quickly recovered. This economic attractiveness makes it a compelling entry point for sustainability efforts.

Addressing water heating can also have wider positive impacts on a business. One area which has seen far greater focus since the COVID-19 outbreak has been improved Indoor Air Quality (IAQ). Renewable water heating solutions such as air source heat pumps and solar thermal as well as electric boilers eliminate the need for combustion processes, reducing harmful emissions and potentially improving air quality for occupants.

Diverse solutions, from upgrading equipment, especially gas-fired to more efficient gas or gridelectric, and utilising renewables such as solar thermal and air source heat pumps can be tailored to various building sizes, budgets, and hot water demands. This scalability makes hot water systems a readily addressable target for sustainability initiatives, with easily quantifiable impact that can be demonstrated to stakeholders. Critically, many water heating efficiency measures offer attractive payback periods, this is especially true of solar thermal where up to 30% offsetting of annual

By demonstrating commitment to sustainability through water heating upgrades, companies not only meet regulatory compliance helping to avoid potential fines or penalties, but can demonstrate active corporate social responsibility which resonates positively with customers, employees, and investors, boosting brand image and reputation. This function of a business is increasingly being recognised, with notable examples of organisations across the leisure and catering markets in particular, embracing a sustainable approach to enhance engagement with customers and define services from competitors. This also resonates with employees, meaning that an initial focus on water heating,

unlocking sustainable buildings

which is both familiar and often business critical can be a starting point for engaging employees in broader sustainability initiatives, fostering a culture of environmental awareness and responsibility.

So where do you begin? The most valuable, yet possibly single lowest cost, activity you can start with is to conduct an energy audit to assess your buildings’ hot water consumption patterns and identify key areas for improvement. Adveco provides a comprehensive service that incorporates live metering of your system and creates an accurate, cost-effective system design that can deliver carbon reductions and meet all your business hot water demands. This provides the data you need to evaluate any upgrade and a benchmark against which to explore various alternatives all available from Adveco, whether high-efficiency gas or electric boilers, heat pumps, and solar thermal systems, which can be deployed in isolation, although most renewables still work best when deployed to supply system preheat as part of a hybrid system. It also enables consideration of other factors like budget, space constraints, and fuel availability, which all factor into launching a sustainable strategy for a building. Working with Adveco at this early stage gives you access to expert guidance from qualified professionals who can provide necessary consultation to determine the most suitable approach for your building’s specific needs and provide a working design that can help secure funding from within the organisation, or externally via government grants, financial incentives, or green loans to offset the initial investment costs of your chosen system design.

The most consistent issue we see in commercial hot water systems is oversizing, whether through a lack of understanding of application design or

concerns over providing suitable backup to ensure system continuity. The result of oversizing is however always the same, unnecessary capital costs for system supply, installation and ongoing excess operational costs associated with higher energy demands and therefore greater carbon emissions.

Correct sizing with metered data can reduce the costs of purchasing and installing new hardware, potentially saving tens of thousands of pounds depending on the scale and complexity of the DHW application. Recognising a need for lower-cost electric systems, Adveco has developed the awardwinning FUSION range, combining an electric boiler, a specially designed cylinder and pipework that is fast to install and resilient to operate. Iterations with a monobloc air source heat pump deliver a reduction of up to 56% in carbon emissions over equivalent gas-fired systems. Integration of solar thermal to deliver mid-system heating reduces demands for water heating by as much as 30% for further carbon cutting and reduced operating costs. Because the systems are now more accurately sized, even the additional upfront capital investment associated with a more complex hybrid system can be offset for a more rapid return on investment.

With a live metered dataset, you gain insight into those prospective carbon reductions and operational costs of the new system. These can be tracked and monitored against, to demonstrate real-world savings in energy consumption and emission reductions, which can be applied toward regulatory compliance as well as used to celebrate achievements by sharing sustainability efforts with stakeholders through transparent communication.

Whichever route is decided upon, organisations should choose environmentally responsible suppliers and prioritise products with low environmental footprints as part of the procurement process. Increasingly building consultants will factor this into a project design, calculating the embodied carbon of any new system, whether water heating, space heating, ventilation and so forth. It’s an important consideration when launching a sustainable strategy, ensuring that a project meets, or preferably exceeds current building regulations ensures projects are not held up or shelved, which will be costly to both the business and the environment.

While water heating serves as a powerful launchpad, achieving true sustainability requires a holistic approach. Once successful water heating initiatives are implemented, businesses can leverage this momentum to expand their sustainability efforts by investing in wider energy efficiency across other building systems such as lighting, ventilation and especially space heating, all of which can require greater levels of physical alteration, operational disruption and accompanying costs. Also, greater attention should be given to further integration of renewable energy, exploring options for onsite renewable energy generation such as installing solar PV panels alongside the higher-efficiency solar thermal collectors used in water heating. PV enables the generation of electricity that can be deployed to a range of building systems. Since PV requires greater roof space than solar thermal, clear decision-making is required when available space for solar collection is limited, with solar thermal recommended to be prioritised as the more effective means of delivering water heating for a smaller physical footprint.

Focusing on water heating presents a strategic and impactful starting point for commercial buildings embarking on their sustainability journey. By addressing this often-overlooked area, businesses can achieve significant energy savings, emission reductions, and tangible business benefits. Furthermore, this initial success creates a springboard for wider sustainability initiatives, ultimately contributing to a more responsible and environmentally conscious future. Remember, sustainability is a continuous journey, and by starting with water heating, businesses can unlock a pathway towards a greener and more sustainable future.

Calls for global action

Bluewater calls for global action on PFAS contamination on World Water Day 2024, says manufacturers should assume full responsibility and halt production.

In response to recent findings exposing the presence of harmful PFAS contaminants in the tap water of 70 million Americans, Bluewater, a pioneering brand delivering water purification solutions and beverages, is urging for increased public vigilance and intervention from national health and water authorities this World Water Day 2024. Bluewater is spotlighting the intensifying global crisis of water contamination by PFAS persistent chemicals, now widely detected in tap water worldwide and posing a threat to human health.

“Our mission at Bluewater is to protect people by preventing hazardous chemicals such as PFAS from getting into their bodies. PFAS isn’t a localised issue. It’s a global health crisis spiralling out of control,” says Bengt Rittri, a leading Swedish environmental entrepreneur who founded & leads Bluewater as CEO.

In recent investigations to raise

public awareness of the problem in London and Stockholm, Bluewater found evidence in both cities of worrying levels of the most hazardous PFAS chemicals, PFOA and PFOS.

“As we commemorate World Water Day 2024, Bluewater encourages everyone to consider tap water quality and to take action towards better health and a sustainable planet. We also urge the manufacturers of PFAS chemicals to take responsibility for the pollution they are causing and — preferably — stop their production of such chemicals entirely,” said Bengt Rittri.

The benefits of a bivalent approach

When it comes to decarbonising buildings it’s crucial to balance effective heating with low upfront investment and low running costs – Chris Newman, Zero carbon design team manager at Mitsubishi Electric, explains

We all know that decarbonising the UK’s building stock is vital for hitting the country’s net-zero targets. At the same time, this can pose challenges for building developers, energy managers, installers and even tenants. One area of complexity is how buildings are heated, because heating has traditionally contributed significantly to overall building emissions, and changing how we heat spaces is high on the net-zero agenda.

But while effective in helping to reduce carbon emissions, changing how we heat spaces isn’t always simple. For example, traditional gas-fired heating systems operate with relatively high water flow temperatures of 70-80ºC (in comparison to today’s typical designs of ≤55ºC). Swapping to an electrically driven alternative to match those temperatures can be straightforward – but it can also have a big impact on the operating cost of equipment.

This is made particularly apparent by the current disproportionate cost per kWh of gas compared to electricity, and the capital cost of technologies such as heat pumps compared to fossil fuel alternatives. This is where a bivalent approach can help to balance the ability to decarbonise a space with lower overall costs.

Focusing on utilising heat pumps as part of a bivalent solution, we can consider two broad types of configuration (see Figure 1).

It is typical in the UK for peak space heating capacity (ie. 100% load) to only be required for a small number of hours in the year and therefore this makes up a relatively small amount of the total kWh of heat energy delivered. This then opens the possibility of deliberately undersizing your heat pump in comparison to peak load and only operating it for certain parts of the year, allowing the gas boiler to provide the extra peak capacity or peak flow temperatures when needed – this approach can help to reduce up-front costs and plant space requirements.

We know that operating a heat pump at the lowest possible flow temperature and the warmest source temperature will usually deliver the highest efficiency and lowest operating cost, but we must also consider how any heat generated is emitted into the building

– this is where the infrastructure of the existing system begins to influence the design approach.

The existing heat emitters (fan coils, AHU coils, radiators, etc) must be assessed to understand their deliverable output capacity at different mean temperatures – this will demonstrate what mean temperature is needed at certain ambient conditions to deliver the required capacity. This is a key piece of information needed to model bivalent parallel and bivalent changeover configurations.

Boiler topping up

A bivalent approach can involve a heat pump being the lead heating source, with a boiler topping up when needed. Alternatively, a heat pump can work in isolation, and swap over entirely to a boiler when it can no longer meet requirements.

In a bivalent changeover arrangement, the heat pump is deliberately designed not to deliver the peak flow temperature or capacity of the heating system.

This means that it will only operate up to a specific temperature and capacity chosen, and then it will reach a changeover point.

The heat pump will operate in isolation to the boiler, and provide heat until its maximum flow temperature and capacity is reached. At this point, the heat pump will turn off and the boiler will take over delivering the higher temperature water and increased capacity required to meet the increasing building load.

This arrangement will deliver a lower proportion of annual space heating kWh from the heat pump compared to a bivalent parallel solution, but as the heat pump will not operate at peak design conditions and will not be asked to deliver high flow temperatures, it will benefit from increased efficiency, resulting in a lower operating costs.

A bivalent parallel approach, on the other hand, requires the heat pump to be capable of delivering the peak flow temperature of the system, so it can work alongside a boiler at any time of year. This allows the heat pump to be sized at any capacity and either deliver heat energy on its own when it has the capacity available, or in conjunction with the boiler when the load is greater than the heat pump capacity.

Flow temperature can be either fixed or weather compensated, but the key design principle is that the heat pump is able to deliver the required flow temperature to meet peak heating demands.

This arrangement will deliver a large proportion of heating from the heat pump and will most likely result in the lowest overall carbon emissions. However, operating the heat pump at potentially high flow temperatures and low ambient conditions will reduce its efficiency, meaning that this configuration could result in an increased operational cost compared to the gas boiler only system.

Special consideration must also be given to the selection of heat pump to ensure it can deliver the necessary flow temperature and capacity at all operational conditions.

Opting for a bivalent solution – whether parallel or changeover – can be the most effective way to balance effective heating with low upfront investment and low running costs.
