Leaders from some of the UK’s most pioneering organisations have joined forces to explore the role of hydrogen in decarbonising the country’s industry, transport, and domestic heating sectors – which amount to 40% of the UK’s emissions, and the equivalent of 180 million tonnes of CO2.

As part of a UK-wide roadshow on the approach to the much-publicised UN Climate Change Conference (COP26) in Glasgow, the 10-stop tour visited ground-breaking projects across the country. This included Northern Gas Networks’ Hydrogen House – the UK’s first homes to feature 100% hydrogen gas appliances – Thames Estuary, Equinor’s Hydrogen-to-Humber (H2H) Saltend project, Fuel Cell Systems, Johnson Matthey, DNV, and the Shell Learning Zone at the Aberdeen Science Centre.

As part of the roadshow, Pilkington UK – together with HyNet and HyDeploy – shared the news that its Greengate site in St Helens has recently undertaken two pioneering demonstrations of using hydrogen to replace natural gas in powering the furnace.

Each day during the trial, two tonnes of hydrogen were consumed – which could have provided an equivalent hydrogen blend to approximately 30,000 average-sized homes.

Elsewhere, Welsh Water – which announced its net zero by 2040 target earlier this year – shared details of its feasibility work to produce up to 2,000 kg per day of renewable bio-hydrogen at the site – enough to support a fleet of 100 hydrogen buses.

DGA chair Chris Barron, and director of gas networks at Costain, said: “Hydrogen – like many other decarbonised gases – can help us meet the UK’s ever-pressing need for net zero climate emissions, at low cost, with minimal disruption, and while creating thousands of sustainable jobs across the country.

“It has a particularly valuable role to play in the notoriously hard to decarbonise sectors – heavy transport, industry, and heat. As a nation, we rely heavily on these industries, but they account for over 40% of UK greenhouse gases. They’re therefore the elephant in the room if we don’t work together to create a deliverable pathway to a net zero energy infrastructure.”

Now complete, the tour explored the need for a regional focus, as part of the Government’s roadmap and Ten Point Plan, and the impact that the public could have if they were better informed and engaged with the subject.

Each stop was handpicked to help drive the conversation on hydrogen and the role it plays in the country’s energy transition strategy – with chosen locations showcasing their own perspective on the hydrogen agenda, to not only raise awareness at policy level but among regional communities too.

Matt Buckley, UK managing director of Pilkington UK, part of the NSG Group, explained: “We are proud to sit at the forefront of hydrogen innovation in the glass industry. Our team’s collaborations with HyNet and HyDeploy are enabling huge steps forward to be taken, as we work towards the decarbonisation of our activities.

“Both trials have successfully demonstrated that it is possible to use hydrogen to safely and effectively fire a float glass plant. We now look forward to HyNet being fully up and running from 2025 in order to turn these demonstrations into reality.”

Ben Burggraaf, head of energy at Welsh Water added: “Producing bio-methane or even bio-hydrogen is an important step towards meeting our ambition to reach net zero by 2040 and achieving a 90% reduction in emissions by 2030.

“Using the biogas to produce renewable fuels could have up to 10 times larger decarbonisation impact than using it to produce renewable electricity, in particular when combined with Carbon Capture Utilisation and Storage technology – for example, producing food grade CO2.”

Andy Cornell, CEO at ABSL added: “The UK produces 30 million tonnes of waste a year which could generate up to 20 % of our energy needs. Sustainable production of biomethane and biohydrogen is critical for energy security.”

Iain Morley, hydrogen transformation manager at Wales and West Utilities, commented: “Bio substitute natural gas which Wales and West Utilities inject into the network can play a big role in reducing carbon emissions going forward. The HSE exemption of up to 1% hydrogen into the natural gas system delivers up to 5,000 tonnes of CO2 reduction which is the equivalent of 2.5k homes in the local area from the ABSL facility.”

Dr Phil Ingram, senior business development manager, low carbon hydrogen at Johnson Matthey, said: “Johnson Matthey was delighted to welcome the Decarbonised Gas Alliance roadshow to our sites in Teesside.

This is where our scientists and engineers created and continue to develop our award-winning low carbon hydrogen technology, which reduces CO2 emissions by over 95%. Manufacturing blue hydrogen at scale is a critical early step in decarbonisation, enabling us all to achieve net zero emissions targets and limit global temperature rises.”

Through innovation, collaboration, and greater public awareness throughout the regions, hydrogen can play a role in safely, quickly, and cost-effectively decarbonising UK infrastructure – providing the country with a stable pathway to net zero emissions.

Nanosensor and Digital Twin technologies come together at COP26 to help deliver a circular economy as part of the race to zero

 

Deploying billions of highly accurate and secure nanosensors interconnected to a global Digital Twin network can enable real-time monitorisation of emissions within urban and agricultural environments.

Nanosensors and Digital Twins are forecast to be pivotal to discussions between international nations and bodies at COP26 in Glasgow, the UK, from October 31st until November 12th and predicted to have a significant impact on the future of carbon tracking.

This technology collaboration will enable global organisations to reward organisations and people globally for tracking and managing emissions to reverse Climate Change while holding to account countries and industries that don’t.

Sensors can be positioned in every urban and rural space, including major rainforests and polluting cities, allowing global carbon emission tracking with unprecedented real-time accuracy.

Digital Twin technology will calculate the carbon emission data gathered by nanosensors, providing a globally sharable, highly accurate representation of how countries, companies, households, and individuals manage emissions in a way that supports the creation of a circular economy – a key sustainability strategy for the world as well as industry leaders to fight climate change.

This particular model for a circular economy is still evolving in terms of data and metrics, but indicators suggest this approach and enabling technologies such as Nanotechnology, and Digital Twins are vital to holding people to account while rewarding industry, governments, and the public for their work in driving down carbon emissions to net-zero.

Former Brazilian ambassador and diplomat and a Harvard scholar, Arnildo Schildt, has been developing a project based on this new model and will be presenting this at the COP26 summit in Glasgow, UK (October 31st to November 12th) – an event being billed as a catalyst for action and tech adoption in the Climate Change battle.

This project will use nanosensors to track deforestation and pollution to help accurately manage carbon credits and offsets, enabling the reduction of emissions and highly accurate tracking of data on deforestation.

Schildt said: “We have been working tirelessly now for two years developing a model with governments, the UN, international banks, academics and industry partners as well as investors to harness the power of Digital Twin and nanosensor technology to solve two massive challenges for our environment simultaneously.

“We have a delegation going to COP26 and will follow this with other partnership meetings in the UK, Canada and the US straight after the Glasgow event to make this a reality.”

Schildt’s initiative in vital rural areas mirrors the urban and agricultural work conducted by US-based Cityzenith, which uses Digital Twin technology to decarbonise the built environment, tracking, managing, and reducing emissions in buildings across metropolitan areas and major international cities as well as linking this to carbon rewards, credits, and other global incentive programs for sustainability.

Cityzenith was referenced by an independent global research group report from ABI research on the 28th of October, naming the company one of three, including The Ellen MacArthur Foundation and Vodafone, that can deliver the infrastructure required for a functional circular economy.

Currently, cities generate 70% of world emissions. Cityzenith’s international Clean Cities – Clean Future initiative has major world cities joining the program, using its Digital Twin platform SmartWorldOS to reduce carbon emissions in buildings by 50-100%, operating costs by 35% and increase productivity by 20%, another independent report by Ernst and Young report on Digital Twins aligns with this.

Las Vegas and New York were the first two cities to sign up, with projects in Phoenix and others expected to follow over the next few months.

Cityzenith CEO Michael Jansen said: “We are confident that the Clean Cities – Clean Future initiative will demonstrate the combined power of Digital Twin and IoT technology to transform mobility, walkability, and emissions/air pollution, while linking all of this to carbon rewards and other carbon related incentives via one interconnected Digital Twin platform.

“And COP26 can play a huge role in bringing the climate crisis into the public spotlight, by acknowledging and backing technologies such as Digital Twins and nanotechnology to make a difference in the fight to protect the planet.”

The UK will also bring a national Digital Twin program to the summit through Anglian Water, BT, and UK Power Networks, which have partnered to foster better outcomes for the built environment.

The project aims to deliver an Information Management Framework which can ensure secure, resilient data sharing and effective information management. At the same time, the program identifies a range of benefits to society, business, the environment, and the broader economy.

Co-Founder of the World Nano Foundation, Paul Sheedy, said:

“Nanotechnologies such as nanosensors and quantum dots can track and monitor anything, holding and transmitting infinite amounts of secure data around the world.

“Combining nanotechnology with advanced Digital Twin platforms is game-changing for the UN’s Sustainable Development Goals and ESG investors that support such impact investing.”

Nanotechnology and Digital Twins were both named in 2021 as the top 5 tech growth sectors forecast to quadruple over the next five years; each sector is predicted to enjoy a combined growth of more than 400% in that time.

Secure, high quality construction depends on easy to use fastening solutions that are guaranteed to perform well in the long term. Nowhere is this more crucial than when attaching building elements to concrete where fasteners must be able to accommodate many different types of load and remain resistant to corrosion throughout their design-life.

Here is where construction fastener specialist EJOT UK is innovating to support the growth in MMC. Its newly extended range of concrete screws and through-bolts enables the safe, secure and rapid on-site assembly of offsite-produced elements with the assurance of European Technical Assessments (ETAs) and the backing of a globally experienced R&D team.

High corrosion resistance for lasting concrete attachments
Developed specifically to meet the needs of the UK market, EJOT has launched an ETA-approved fastener with enhanced corrosion resistance – the JC6-KB. This is a bi-metallic concrete screw manufactured in A4 316 stainless steel with hardened carbon steel lead threads.

As a result, the JC6-KB is suitable for outdoor Option 1 concrete applications approved for environmental classifications ranging from C1 up to C4, in accordance with BS EN 12944.

Its development reflects how the UK R&D team, supported by the EJOT Group team in Germany, is ideally positioned to ensure local customers have the right products they need to apply in the way they prefer. The overall EJOT product portfolio may be designed to suit a global market, but that does not mean UK customers have to adapt the way they work when choosing the EJOT brand.

In fact, the team in Sherburn-in-Elmet is proactively developing UK-focused fasteners that are gaining traction in overseas markets too, making a positive contribution to the global construction market. This benefits from the EJOT strength that brings together the best of British and German engineering – an internationally respected combination.
An expanded concrete screws range with new application potential

The JC6-KB’s development was in tandem with another major concrete screws advance by EJOT globally. Its new JC2 range of carbon steel concrete screws offers greatly extended scope for achieving a secure, reliable attachment for metal fixtures in Option 1 cracked, non-cracked and hollowcore concrete, as well as other hard base materials.
This enables JC2 self-tapping concrete screws to be used as an alternative to anchors or screw/nylon plug combinations in an increased range of construction applications. This could include attaching façade scaffolding, shelving and handrails to battens, cable racks and formwork.

Importantly, as these concrete screws need no expansion, they can be used closer to the edge of the concrete and at smaller spacings than when using anchors. They are also easy to use and install, with no specialist skills required, which can be a big time-saver on site.

Only a small pilot hole is required, which generates a relatively small amount of dust. Once this is removed from the hole, the screws are simply driven into place  – they offer a good degree of adjustability like a standard wood or metal screw which makes them a versatile choice.

The JC2 range offers six fastener types designed by EJOT’s R&D teams in both Germany and the UK to offer superior performance in-situ along with hassle-free installation. All provide the independent assurance of ETA approval and are tested to offer fire resistance to 120 minutes.

Upgrades to EJOT UK’s ETA approved through-bolt range
Whilst the new range of EJOT concrete screws offers greater versatility on-site, a through-bolt is still often the preferred attachment approach for a whole host of reasons.

Here is where EJOT UK has innovated further. Its range of ETA-approved through-bolts – also known as anchor bolts – is the BA Plus, providing a range of Option 1 anchors suitable for both cracked and non-cracked concrete applications.

It builds on the strengths of EJOT’s established BA range of torque-controlled expansion anchors, suitable for concrete and other hard base materials including natural stone. And the benefits are extensive, including being quicker to install, more secure in thinner concrete and a design that reduces the risk of installer error.
BA Plus provides through-bolts for all the most typical cracked and non-cracked concrete applications ≥ C20/25 up to the seismic Option 1 performance. Backed with the independent assurance of ETA approval, the range offers a dependable solution for numerous applications including steel structures, column base plates, heavy duty racking, cable racks, handrails and facades.

But BA Plus is not the only new through-bolt development by EJOT. Its UK team has also developed a new range of through-bolts for Option 7 non-cracked concrete applications, BA-C NC. This provides a class-leading anchor for many other applications including warehouse racking and stadium seating – again backed by the third party assurance of an ETA.

The superior airtightness performance qualities of the Wraptite® air barrier system from the A. Proctor Group will enhance a new state-of-the-art development at St Dunstan’s College – a co-educational independent school in Catford, London.

Contractor Willmott Dixon will deliver the new Junior School, STEM building and Sixth Form Hub at St Dunstan’s.
Designed by Bond Bryan Architects, the new development will be sited adjacent to the existing historic Headmaster’s House and connected by a glass atrium. Phase one includes a new junior school with specialist facilities for art, music and performance, and phase two includes the construction of the STEM Centre and Sixth Form Hub.
A vital element of the design and construction is to maximise the energy efficiency of the new buildings: Wraptite airtightness membrane, the only self-adhering vapour permeable air barrier certified by the BBA, will form a crucial part of the solution.
The inclusion of Wraptite within the facade will ensure “as-designed” performance, narrowing the gap between as-designed and actual energy performance and reducing the likelihood of potential failures to meet required airtightness levels.
Wraptite is a self-adhesive breather membrane applied externally, quickly and efficiently as part of the rainscreen system. The self-adhesive Wraptite membrane fully bonds directly to the substrate, requiring no mechanical attachment and little seals or tapes to suppress air leakage around junctions or penetrations.
Wraptite combines the critical properties of vapour permeability and airtightness in one self-adhering membrane, providing high levels of protection to the building fabric beneath the cladding. As a result, the Wraptite system allows the substrate beneath to dry quickly and moisture vapour to escape and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion.
Wraptite is compliant with Part B regulation changes and also has BBA approval for unrestricted use in buildings over 18m in England and 11m in Scotland.

With pressure on the construction industry to utilise more sustainable building methods and product choices, specifying a PVC-U solution is increasingly being seen as a way to further drive the green agenda.

Eurocell is supporting sustainability options for housebuilding and commercial projects through its market-leading PVC-U recycling and manufacturing processes that are substantially reducing the amount of plastic waste heading for landfill and helping to tackle the problem of carbon reduction. The company offers an extensive range of high performing PVC-U window and door solutions that not only look good, but also help organisations satisfy their sustainability ambitions.

Momentum is building across all parts of society as consumers, businesses and politicians look for answers to the escalating climate crisis.  Consumers want to see action and as a result, companies are looking closely at how their activities and processes are impacting the world. In the UK, the government has set out bold carbon reduction targets as part of its net zero strategy.  One key area is the nation’s housing stock and policy makers looking to deliver a difference have the construction industry firmly in its sights.

The new Part L Building Regulation and the Future Homes Standard – which is seeking a 75% reduction in CO2, compared to current levels, in new builds by the middle of the decade – is tasking architects, specifiers, developers, and construction firms with uncovering the right construction methods and building fabric product choices to support a more sustainable, energy efficient and less wasteful future.

PVC-U is already playing its part in helping the construction sector meet important environmental and regulatory obligations.  Set against other potential product choices such as aluminium or timber composite, PVC-U offers long-term durability and high performance, attractive aesthetics to support design visions, cost effective value and, through Eurocell’s vision and industry leading recycling processes, a truly sustainable answer.

Recycling with a purpose
Eurocell has been committed to supporting the aims and ambitions of recycling for over twenty years.  Recognising a corporate need to do what is required to minimise plastic waste and where possible reuse materials across large scale manufacturing processes, the company has moved from externally purchasing recycled plastic to the establishment of its own nationwide waste recycling system, used to supply Eurocell’s manufacturing operation with recycled plastic raw material.

Such has been the success of Eurocell Recycle, the result of its processes now see it account for around 80 – 90% of all the material Eurocell’s manufacturing business requires to generate an extensive range of brand-new extruded plastic products.  As part of this, Eurocell now recycles around 3.5 million discarded frames per annum, with such post-consumer waste combined with virgin PVC-U to produce extruded material used for new frames and other products such as cavity closers.

Without this service, a high proportion of the PVC-U waste generated by large manufactures, fabricators and installers would simply end up in landfill and contribute further to the waste disposal challenge the UK continually faces.

‘Closed loop’
The ‘closed loop’ system is a six-stage recycling process.  Starting with a national collection service operated by Eurocell Recycle.  Old and discarded PVC-U windows, door frames and other PVC-U offcuts are collated by Eurocell Recycle’s fleet from company locations and waste management centres across the UK.  On arrival at one of the recycling processing plants, the material undergoes an extensive sorting and separation process which divides metals, white polymer, and coloured materials, as well as capturing material which is ultimately non-recyclable.
After a transformative process which creates a powder or pellet form that matches virgin PVC-U material, the recycled plastic is used by Eurocell to manufacture its extensive range of extruded PVC-U products.   The fabrication of new products such as window and door profiles then follow, leading to the installation of many new products in homes and commercial buildings ultimately fashioned from thousands of old windows and door frames that have reached the end of their working life.

And the recycling process promises much for the future.  New PVC-U windows using recycled polymer can last up to 35 years and the material can be further recycled up to ten times delivering ongoing sustainability benefit for generations to come.

PVC-U performance
When set against alternative product choices for windows and doors, PVC-U is proven to deliver an enhanced thermal performance. Combined with effective glazing solutions, buildings can be better insulated and use less energy with PVC-U’s ability to offer a lower U-value for lower cost.   For large scale housebuilding developments or commercial projects, the option to achieve excellent thermal performance results through a cost-efficient product choice without compromise, is a reason why PVC-U and popular Eurocell solutions such as MODUS and LOGIK windows that contain high levels of recycled content, are becoming the sustainable product choice for many.

Proven benefit
With carbon saving the true test of strategic sustainability plans, Eurocell is committed to working with the sector to deliver tangible results and undoubted benefit.
By transforming waste PVC-U material destined for landfill into a high performing, thermally efficient, aesthetically pleasing, and cost-effective PVC-U window and door solutions, Eurocell is the proven sustainability choice for the construction sector at a time when it is needed more than ever.

By James Mead, projects director at Saint-Gobain Weber.

If you ask most people what their house is made of, the chances are they’ll tell you it’s made of bricks. In fact, around 70% of the UK’s new homes are built with a brick façade proving that this traditional style has retained its popularity since 7000BC, when the people of Jericho made the first bricks from mud and dried them out in the sun for hardening.

Today’s bricks are kiln dried and are much heavier than a mud brick – so the costs in terms of freight, emissions, weight, space, and storage are significant. The other pressing issue with bricks is bricklayers: They’re in very short supply and laying bricks is such a skilled craft, it takes a long time to gain the experience to do a decent job.

With a call for bricklayers to be added along with lorry drivers to the Government’s Shortage Occupation List, and existing bricklayers charging a premium, we need to find a way to construct buildings that are traditional in style but modern in construction.

Those building homes in the social housing sector also have another concern: the Government’s Affordable Homes Plan, delivered through Homes England, specifies that the projects it funds must contain a minimum of 25% MMC. It also sets a measure against which MMC projects will be assessed – the Pre-Manufactured Value (PMV). This is the financial proportion of a project’s gross construction cost through pre-manufacturing. To pass Homes England’s MMC test you need to have at least a 55% PMV.

 

Calculating PMV

To calculate a building’s PMV, each element that is delivered through an MMC process or product will add to the overall percentage. There are seven categories awarding percentage points. For example, in category one is ‘Pre-manufactured 3D primary structural systems’ like a volumetric modular housing unit. This will give you the highest percentage. In category three ‘Pre-manufacturing components (non-systemised primary structure) components’ – such as beams, staircases or trusses would also boost your percentage.

Category six deals with building products and systems that reduce labour on site and improve productivity. One area where it’s easy to specify a PMV improving element is using a modern alternative to traditional brickwork.

Encouraging MMC in the private sector

Of course, it’s not just in the social housing sector where the principles of MMC and increasing the use of off-site manufacturing are important. Private housing developers must also adopt MMC to play their part in the fight against climate change.
The construction industry is responsible for 38% of CO2 emissions, so any products that can reduce both wastage and HGV deliveries to sites are going to make a huge impact on this figure. MMC also addresses labour shortages by using products made in factories without the need for specialist skills, and off-site manufacturing reduces construction waste which accounts for 59% of waste produced in the UK.

Traditional in appearance, modern in application

Saint-Gobain Weber has developed weberwall brick to help bridge the gap between traditional and modern methods of construction. We have developed a façade alternative that gives the appearance of brick but can be fitted without the need for specialist labour on site. Once applied, it feels and looks just like the real thing.

Ideal for developments or refurbishment projects where planning permission requires a brick façade, weberwall brick is lightweight and quick to apply taking around 17 minutes to install 2sq m. Cladding the equivalent area in brick slips takes just under an hour and when the whole build is taken into account it can be up to 50% faster than using a traditional brick slip
The lightweight brick slip system can be applied directly to the substrate with a specially formulated render. It is then pointed in the same way as a standard brick so, once installed, looks no different to traditional masonry.

It can be programmed into CAD systems to minimise waste and is designed for use with the most commonly used MMC systems so ideal for steel, wooden frame and panellised systems. weberwall brick forms part of BBA approved systems and is suitable for new build or refurbishment projects where it can give a building a completely new look.

If developers are going to truly grasp MMC to combat the housing crisis through centralised funding, they are going to need to adopt creative and innovative solutions to increase their project’s PMV whilst conquering the multiple difficulties posed by today’s construction industry, weberwall brick is certainly up to the challenge.

TG Escapes Eco-Buildings provide modular teaching block for new High School

The High School Leckhampton, is a brand new co-educational comprehensive school that will serve south Cheltenham. It is being built to cater for an expansion in pupil numbers at secondary level in the area. The school has been commissioned by Gloucestershire County Council but is being “sponsored” and developed by Balcarras.

TG Escapes Eco-Buildings were appointed to provide a stand-alone eco-building to accommodate the school’s intake in time for September 2021. The modular timber frame solution provides a fast build process with minimal disruption, and delivers a bespoke permanent building designed to last 60 years or more.

Ian Davidson, Assistant Head and Jeff Arris, Network Manager at Balcarras School explain the background and their experience of the project.

Why was the building needed?
IAN: Balcarras School were awarded the contract for an entirely new school, to teach 900 11-16 year olds, which was due to open in time for the start of the school year in September 2021. The initial phase of opening was for 120 Year 7 students with subsequent yearly intakes increasing until the school will be operating at full capacity with 5 year groups of around 180 pupils each.
Towards the end of 2020 it became apparent that the new school building would not be completed in time to welcome the initial intake of students. The existing school was operating at maximum occupancy and there was simply no space available to accommodate the new students.
The decision was taken to build a modular suite of 4 classrooms on the existing school site, each designed for around 30 Y7 pupils, to be used for classroom-based subjects (maths, English and social sciences). Science, art, DT and PE lessons will take place within the main school facilities.

What was the process for selecting the bulding provider?
JEFF: The year previously, the existing school had engaged with 3 contractors to provide a modular building to extend its IT facilities. TG Escapes won the tender process but it was ultimately decided to not proceed with the project.
However, TG Escapes had sufficiently impressed that they were selected as one of the 3 contractors invited to tender for the new project and again were the preferred choice. The governors were naturally concerned about timely delivery and potential overspend and engaged Evans Jones consultants to oversee the build, which commenced in January 2021.

How did you find the process?
IAN: I thought it was quite brilliant. My biggest concern was that the building would be completed on time, but I have never seen a building go up so quickly. Throughout the build the project manager was very approachable and easy to deal with. Any problems were immediately solved, avoiding any interruptions to the day to day running of the existing school site. All potentially disruptive operations such as crane and material deliveries were organised to fit the school timetable.

JEFF: The site was well managed and the project manager was fully engaged with the school throughout the build, securing agreement before each phase. Regular meetings between the school management team and the project manager were handled thoroughly and efficiently and the building was completed weeks ahead of schedule in May.

What do you think about the building’s quality now it is in use?
JEFF: It is good and functionally it is working well, particularly pupil flow. We are expecting the outside decking areas to be a very useful space.
Ian Whilst there have been a few snagging issues these are being well dealt with promptly. The finished look of the building is really good and reminds me of a “Grand Designs” project. The parents love it and the feedback from staff and students is also very positive. It feels both spacious and luxurious.

How important were the eco credentials?
IAN: Very important. Zero carbon and environmental issues have become a big consideration across the education sector.
Jeff The speed of construction versus a traditional build process was also of high importance. I was impressed by the lack of waste, helped by the donation of spare materials to the existing school.

Heat Networks are an increasingly popular solution for urban developments, promising efficient heat for occupants, reduced maintenance, and a much simpler transition to low carbon heat in the future. One challenge these projects pose is that domestic hot water pipework must be maintained at a constant warm temperature so that it is always available for use. As a result, gaps in the insulation around services, or use of insufficient pipe insulation, can raise heating costs and increase overheating risk in the summer months.

To address this, developers are increasingly looking to offsite approaches, allowing services to be fabricated in modules before being installed on site. In addition to accelerating onsite processes and ensuring consistent quality, this can also allow for improved access during fabrication and pre-testing prior to installation. To further support project teams, CIBSE has released CP1 Heat networks: Code of Practice for the UK (2020), setting over 500 minimum requirements for these systems.

CP1 and the growth of heat networks
Heat networks distribute heat from an energy centre/s to either an individual building (communal heating) or multiple buildings (district heating). One of the key advantages with this technology is that it is ‘fuel agnostic,’ meaning a whole range of sources can be used for the energy centre. It is therefore possible to install a network which initially uses a gas-powered energy centre, then transition to a low-carbon alternative as they become available.
Whilst this technology has been used globally for decades, it is still relatively new here in the UK and CP1 (2020) has been designed to assist effective deployment. The insulation of secondary pipework (the pipework that runs inside the building) provides a good example of how it works— providing simple minimum requirements whilst encouraging specifiers to look to enhanced specifications.

Pipework Insulation
Objective 3.9.7 of CP1 provides minimum insulation thicknesses for different secondary pipe diameters. In most cases, a 50 mm thickness of either phenolic or mineral fibre pipe insulation is required.
The use of minimum insulation thicknesses, rather than heat loss parameters, is designed to provide clarity but also has limitations. In particular, phenolic insulation is notably more effective at preventing heat loss at a given thickness than mineral fibre. This means that heat losses may increase by between 30% and 39% when the minimum mineral fibre specification is used instead of the phenolic equivalent.
To address this, CP1 also requires project teams to carry out pipework heat loss calculations at the Feasibility Stage (Stage 2) and to create detailed pipework insulation specifications based on project specific parameters at the Design Stage (Stage 3). The benefits of enhanced pipe insulation specifications should be considered during this process, both to reduce energy demand, and minimise overheating risk.
Additionally, CP1 also highlights the importance of ensuring a continuous layer of insulation across all areas of the services and the use of “rigid low conductivity inserts” to prevent heat transfer through pipe support.

East Village
Alternative Heat recently put CP1 principals into action when developing the design, fabrication and delivery of shell and core service packages as part of the heat network for N06 East Village in London. The project features 524 build-to-rent apartments at the former London 2012 Athletes’ Village with the project team including M&E consultants, chapmanbdsp, M&E contractors, Borough ES, and thermal insulation contractors, Commercial Insulation Services.

To ensure efficient delivery, the project was completed to Level 2 BIM and Alternative Heat supplied services in a number of modules, including skid mounted plantrooms, mechanical utility cupboards, laterals and risers which could be simply lifted and installed. Kingspan Kooltherm Pipe Insulation and Insulated Pipe Support Inserts were specified for a range of Low Temperature Hot Water (LTHW) and Boosted Cold Water System (BCWS) pipework within the modules to meet key performance criteria. As Damien McMullan from Alternative Heat explained:
“The development uses a district heating system, so it was essential to keep heat losses from the pipework to a minimum. For this reason, the specification from chapmanbdsp required the pipework to be highly insulated and compliant with the CIBSE CP1 Heat Networks guidance. The combination of Kingspan Kooltherm Pipe Insulation and Insulated Pipe Support Inserts allowed us to easily meet these requirements across the different pipe diameters.”

Complete Solution
Modular building services solutions offer clear advantages for heat networks. By ensuring these meet the requirements of CP1, and looking at how you can go beyond these, it should be possible to maximise the long-term cost, emissions and energy savings on these projects.

Top performing FR panels add the finishing touches to MMC projects

Panels are the perfect addition to a modern build. A consistent, repeatable product that is quick to install and available in standard sizes across a range of decorative finishes, they offer the perfect finishing touch, whatever the design.

One consideration high up on the agenda for specifiers when designing public buildings, such as schools, hotels and medical centres, is fire protection.  Reducing and managing the risk of fire is an essential consideration and there are a range of panels available on the market that can help.

Here, Lathams explore three of its top performing Fire Resistant (FR) panels. Structural product SMARTPLY FR B is a good place to start. Used for floors and walls, it is a moisture resistant, flame retardant Euroclass B panel (B-s2, d0).  What makes this product unique is the way in which it is produced. Individual flakes of wood are treated with a water-based FR solution before the panel is manufactured. This means that the fire protection is maintained throughout the panel, so it can be cut or machined without losing any of the fire performance. The boards are produced using ContiRoll® technology, making this a highly flexible product because it can be rolled out to any size. Essentially, the OSB panel goes under rollers on a continuous conveyor and is only cut once the desired length has been reached. With sizes of up to 2.8 x 7.5m achievable, they are ideal for the MMC sector.

Garnica Fireshield is also rated Euroclass B (B-s1-d0). It is a modified plywood that undergoes an innovative ply-to-ply process which results in strong flame retardant properties. Like the SMARTPLY FR B product mentioned above, this process means that it can be cut or adapted without negatively affecting the fire performance.  It is a lightweight product making it perfect for the offsite market; whether installed within the factory or sent directly to site, it is easy to transport and handle. Sourced from sustainably managed European poplar forests, Garnica Fireshield is often used for ceilings, walls, doors, frames and partitions. Suitable for a range of sectors, its certifications make it one of the best performing wood products, offering low carbonisation, low smoke emission and an absence of flaming particles in the event of a fire.

For those looking for something with more decorative options, High Density Fibreboard (HDF) Valchromat FR provides fire resistance across a range of 11 colours.

The boards are ‘through coloured’, with the dye embedded throughout the panel. This means that it can be easily machined, offering clean cuts and a uniform finish with a consistent colour. It is perfect for locations that need a bit more colour but do not want to compromise on performance.

The Euroclass B-s2,d0 Flame Retardant version is perfect for branded environments that perfectly blend in, and is heavily utilised in commercial fit outs, retail and hospitality environments, exhibitions, museums, and schools.
