Regulation answer

Regulations are a necessary part of any industry, and although they may be frustrating at times, really do have the ability to make improvements all round. It’s through regulations that working practices are made safer, and through them too that quality of work can be vastly improved. That is to say, when said regulations are done the right way.

The UK construction industry is currently in quite a transformative state. In fact, it seems like all we’ve been hearing about recently is new regulations coming into force and upcoming standards that are on the horizon. Naturally, the biggest of these change to come is the ever impending Future Homes Standard 2025 (FHS).

I’m sure you’ve all heard more than your fair share about how this is set to reform the way we build properties, drastically reducing the carbon emissions involved through changes to fabric, heat sources and so on. While the concept of these ideas is sound and we are in a losing battle with the health of our planet, there’s a way to go about change and if we look at the government’s track record. Well, I’m not exactly hopeful….

Let’s look at one recent new regulatory change in the form of Biodiversity Net Gain (BNG) for example, which enforces enhanced biodiversity in new developments by a net 10%, preferably on-site but with an option to buy off-site credits too. The roll out from the Department for Environment, Food and Rural Affairs (Defra) first came to major developments in February, then hit smaller developments in April, with nationally significant builds set to be affected from November 2025. With the first two stages already implemented, it’s safe to say the reception hasn’t been entirely positive.

In fact, a rather damning report from the National Audit Office (NAO) showed that Defra hasn’t sufficiently planned ahead for long-term success. While local authorities were given funds to prepare for the changes, these were to be used at the discretion of the local authorities and no extra funds are being provided to actually monitor or enforce on-site gains. What’s more, Defra won’t be centrally monitoring how well onand off-site biodiversity gains are being enforced by local authorities, nor does the department have a legally compliant mechanism to spend income from statutory credit sales to enhance biodiversity (if they are used as a last resort because the private market can’t provide enough off-site credits).

More importantly than all of this though, is the sheer lack of communication to small developers from those responsible for the new regulations. As I mentioned earlier, regulations do have the capacity to really improve an industry. But when most of those in the industry don’t know what these changes are, and the infrastructure as a whole hasn’t been prepared to support them, how can we expect regulations to succeed? It seems to have almost fallen on the shoulders of manufacturers to educate the industry and while it’s great that they’re doing this, they shouldn’t have to.

If a recent survey from Polypipe is anything to go by, the FHS isn’t going to be any different. Almost half (49%) of housebuilders say that their business is not prepared for the FHS, and a further 61% think it will be extremely challenging to meet the legislation. So, will the powers that be learn from their mistakes and actively try to support the industry through these monumental changes? We’ll have to wait and see.

SPECIAL REPORT: TIMBER FRAME

An integrated weather barrier system is heralding a new era in weatherproofing for timber frame homes.

Brian Adams, Arclin’s Senior Director of International Business explains more.

Proof positive!

I n May, Arclin announced it is launching Arctek® Dryshell™, an integrated weather barrier system that provides an alternative to traditional housewrap products for timber framed homes. Here, we speak to Brian Adams Senior Director of International Business at Arclin to find out more.

(PHPD) Arclin is a US manufacturer, so for those who

don’t know, tell us a little about the company?

(Brian Adams) Arclin is based in Atlanta and manufactures polymer and engineered products for industrial applications in the construction, agricultural, weather and fire protection sectors. We recently purchased UK panel processor Trade Fabrication Systems (TFS) to establish and grow our market share in the UK and Europe.

(PHPD) What is Arctek Dryshell?

(BA) Unlike any other weatherproofing solution for timber frame homes in this market, Arctek Dryshell is a proven and established technology in America.

We believe it will be a real game changer for housebuilders across the UK and Europe. The precision-engineered overlay is thermally bonded to OSB or plywood sheathing boards in the factory.

This means timber frame walls and roofs, SIP systems and cassettes are delivered to site with the weatherproofing in place, massively speeding up installation.

As a result, it delivers a weather-tight shell more quickly, overcoming the risk of moisture penetrating timber panels during construction, whilst its vapour

“In the UK alone, there’s a deficit of about four million homes, so there’s pressure on housebuilders to quickly and efficiently deliver more properties.” permeability allows humidity to escape the building envelope to avoid interstitial condensation.

(PHPD) Why have you launched Arctek Dryshell in the UK now?

(BA) The time is right. There’s currently a significant and growing housing crisis across Europe. In the UK alone, there’s a deficit of about four million homes, so there’s pressure on housebuilders to quickly and efficiently deliver more homes. At the same time, stricter legislation means these homes must be more sustainable and achieve high standards of quality and performance.

We know approximately 40% of manmade emissions come from construction, so new homes must be both energy efficient and low carbon in construction. Timber is a good insulant and using it in construction can reduce the embodied carbon of a property by up to 60%. As a result, the Government published the ‘Timber in Construction Roadmap’ to grow more trees and unlock the potential of this construction material.

There’s a huge opportunity for growth. England’s use of bricks and mortar means it’s lagging behind other markets – just 9% of new homes are built from timber compared to 92% in Scotland. But this will change. We commissioned a report by analysts Alfry which showed the ‘addressable market’ in Europe for OSB, plywood and SIPs for timber frame construction will rise from 35 million m2 annually to 50 million m2 in 2025. The greatest potential is seen in the UK, with a current addressable market of 13 million m2.

This solution will help housebuilders overcome the competing pressures of needing to comply with stricter legislation while delivering homes at scale and speed so they can tap into this growing market.

(PHPD) How does the product differ from traditional solutions?

(BA) The obvious difference is how it’s installed. Housewrap products are fixed to

the outer face of timber framed structures.

This takes time and effort. Installers must ensure laps go in the right direction and undertake tricky installation details around window and door openings.

In contrast, Arctek Dryshell is applied within the factory. This means both the timber frame and the weatherproofing layer is installed in one seamless process.

Once the panel has been installed, there’s no details, and joints are simply taped to provide instant protection for the substrate.

(PHPD) What are the benefits to housebuilders?

(BA) Using timber products with Arctek Dryshell removes an entire stage of the construction process, significantly reducing time and costs. It means skilled tradespeople can focus on what they do best rather than spending time installing housewrap.

The product also supports regulatory compliance. Under Part L, every new home must be tested for airtightness. Products are selected for performance, but that can be undermined by poor installation.

Housewrap products are loose. Failures in correct detailing around doors and windows can reduce performance, but the biggest issue is tearing. This can happen during installation, but housewrap can also be inadvertently damaged by other trades, and this minor damage can become a full-scale rip if it’s caught by the wind. As a result, moisture can penetrate behind the wrap and into the frame structure, and airtightness is compromised too.

Because Arctek Dryshell is thermally bonded to the wood, it won’t be damaged on site. It creates a waterproof barrier for the wood-based panel, acts as a vapour control layer, promotes thorough drying to the outside and offers better prevention of air leakage than housewrap products.

As the housing crisis continues to grow, we know pressure on the industry will only increase. So, this launch is about helping to address fundamental issues for housebuilders that will ease those pressures – performance, quality, time and cost.

SPECIAL REPORT: GEORGIAN DEVELOPMENT

Nigel Booen, chartered architect and Director of Design, Boyer, looks at ‘gentle density’ and whether Georgian style development is the best means of delivering it

Nigel Booen, chartered architect and Director of Design, Boyer

12 July/August Professional Housebuilder & Property Developer

Gently does it D ensity, often expressed (presumably for political purposes) as ‘gentle density’ is a central theme of the National Planning Policy Framework and, as such, directly influences the development of all new communities.

And, at the time of writing this, it looks like it’s here to stay: the Georgian style is clearly a favourite with political parties and local communities. Building More, Building Beautiful: How design and style can unlock the housing crisis, a forerunner to the work of the Building Better, Building Beautiful Commission, used extensive polling which showed that in the design of new homes, traditional building design was much preferred over contemporary architecture. Across all demographics, a large majority agreed that newly built properties should fit in with their surroundings. Support was used to substantiate the claim that NIMBYism (standing for not in my back yard!) can be overcome if design better reflects people’s desire for traditional architecture.

The style is exemplified at Poundbury, the new community developed by the Duchy of Cornwall in Dorset, which is Georgian not only in its density but in every aspect of its design. Properties at Poundbury sell for 55% more per hectare due to a combination of public preferences and higher densities, according to analysis by Create Streets.

To understand whether ‘gentle density’

can benefit the quality and quantity of new developments requires a definition – not having had a place in the planning lexicon until now. That’s where the problems start. ‘Density’ is relatively straightforward as it can be measured in quantifiable terms; a relatively simple function of homes and site area. ‘Gentle’ means very little in a planning and design context but its function, on any plain reading, is clearly to limit density rather than increase it. The deceit in the wording is it purports to enable a higher volume of housebuilding, while also giving leeway to appease anti-development communities as necessary.

It is no coincidence that most political parties have promoted the Georgian style of architecture as synonymous with gentle density. Not only is this style of architecture popular, but Georgian-style housing can achieve up to 40-60 homes per hectare, which is significantly more than the average housing development – typically 30-35 homes per hectare on comparable greenfield sites.

However, this comparison should be considered in context. While 60 homes per hectare may be considered dense in rural and suburban areas, it bears no comparison to a 40 storey apartment block in a city centre location.

Furthermore, many question whether the Georgian style of architecture espoused at Poundbury should be mandated as the future of good design.

012_PHPD_JUL_AUG24.qxd_Layout 1 27/06/2024 23:42 Page 13

Georgian architecture may represent the very best in design to some; to others the repurposing of a centuries-old style is regarded defeatist, retrograde, even ‘Disneyesque’.

Perhaps schemes such as Poundbury will be effective not only in encouraging NIMBYs to accept development, but in even higher density than they might have otherwise tolerated.

But this only works in those areas where the average density is lower than a typical neo-Georgian development. Take that approach in London and the perfectly acceptable densities currently achieved will be lost, homes will become increasingly scarce, house prices will sky-rocket and local centres will become desolate and unviable.

Over the last parliament we have seen 'beauty' and ‘gentle density’ embedded in both planning policy and case law.

Through design codes, we have the structure to deliver, as the then Secretary of State Robert Jenrick said introducing the concept in 2020, a ‘higher regard’ on quality and design – one, he said, which draws on ‘the idea of design codes and pattern books that built Bath, Belgravia and Bournville’.

But we still lack anything constructive to prevent other housebuilders from failing on ‘beauty’ grounds. This was clearly demonstrated last April when the Secretary of State Michael Gove called in and subsequently refused planning permission for a 165 home development by Berkeley Homes in Cranbrook, Kent. The outcome of the Berkeley case was ‘no’ but not ‘no, because beauty is…’. This potential test case is crying out for a clear definition of beauty, a clear selection of criteria and is yet to be addressed.

In practice this (and similar, subsequent decisions) makes the whole process of designing new developments more fraught with uncertainty. And uncertainty is the last thing we need at the moment, with so many other uncertainties with the planning system. Unfortunately, it provides ammunition for planning committees to refuse other schemes on similar grounds. Without anyone knowing what the benchmark is, design could be an easy target to justify refusal – which, as some have suggested, was perhaps the Government’s main objective.

SPECIAL REPORT: BIODIVERSITY NET GAIN

SME housing developers who are struggling to navigate the complexities of Biodiversity Net Gain (BNG) and Sustainable Urban Drainage (SuDS) legislation need look no further than BioScapes

Terry Smithson is Head of Nature Based Solutions at BioScapes

14 July/August Professional Housebuilder & Property Developer

Easy being green “Y

ou might think that soil and the grass that grows through it are basic commodities but we’ve always pushed the boundaries of performance and innovation,” enthuses Terry Smithson, Head of Nature Based Solutions at BioScapes – part of the Rolawn Group. “At the same time we want to deliver easily adoptable and very practical solutions for our housebuilder clients.” It’s an attitude which positions the ecology and horticultural specialists as the perfect partner in a new and often unfamiliar legislative landscape.

Biodiversity Net Gain (BNG) as a concept has been a long time coming but that doesn’t mean that the confusion around compliance has abated, especially amongst smaller developers. In January of 2024, legislation was introduced to compel housebuilders who were constructing 10 or more units to make a 10 per cent improvement in BNG, with some local authorities asking for as much as 20 per cent. In April 2024, that requirement was extended to smaller new build schemes of one house and upwards. In effect, there are now very few exemptions.

So, how does that translate on the ground? Essentially, planning permission will be dependent on an assessment of

the level of biodiversity on the land, both prior and post development. This can be achieved on the actual site of the new property, or it can be achieved off-site, whilst there’s a third option of purchasing statutory biodiversity credits.

For a smaller developer, who is invariably focused on a quality build rather than quantity, there are obvious benefits to the on-site approach, not least providing the homeowner with an aesthetically appealing installation through which they can enjoy the acknowledged well-being benefits that engaging with nature brings.

Attractive and creative biodiversity installations will equally offer the added selling point of diversifying a property from the competition.

Sustainable Urban Drainage (SuDS)

It’s not just BNG that needs to be taken into account either, because developments with more than one dwelling must now demonstrate that they are implementing Sustainable Drainage Systems (SuDS). The rationale for their implementation including climate change, more frequent extreme weather events, with consequent water run-off and flooding – is well known, but it again begs the question what does it mean in practice?

014_PHPD_JUL_AUG24_Layout 1 27/06/2024 23:53 Page 15

“Not only are you making a statement about your green credentials, you’re also welcoming them to their new home with outdoor features that will enhance the build quality.”

“As a starting point, the four SuDS pillars are water attenuation, as well as the cleaning of water run-off from impermeable surfaces,” continues Terry. “It also needs to include amenity benefits, and promote biodiversity, with that final point feeding directly back into the BNG legislation.

“Whilst volume housebuilders are prepared for the new BNG and SuDS regimes it’s fair to say that there’s a distinct lack of awareness amongst SME developers,” Terry adds. “Even if they are mindful of what’s required, there’s still a knowledge gap of what solutions they need and where to source them.” Indeed, there has already been criticism from the National Audit Office and the FMB which has cited additional costs and a lack of preparedness on the part of some local authorities.

The message from BioScapes, however, is that it doesn’t have to be a complex or onerous process – and the company has the product range, and expertise, to prove it. “Our units are all-in one solutions that come together to address SuDS management and biodiversity requirements. They look good, promote wellbeing, can be comfortably introduced into relatively small spaces, and are easy to maintain.”

There’s a whole range of BioScapes products that will help housebuilders conform to BNG regulations and the same principles remain consistent throughout.

Product range

The most compact on offer is the WildPod Mini®, which brings together ten interconnected habitats in a 35 x 56 x 60cm wooden unit, with the addition of a unique rainwater catcher. Delivered in flat pack form, it’s easy to assemble and position, only requiring the addition of up to 80litres of topsoil and compost, 10litres

of clay for the reservoir habitat, and 6litres of deadwood habitat materials. Once in place, you can watch the wildlife colonise a protected ecosystem where species will interact as they would naturally.

At the other end of the scale, the patented BioCube® can be as large as 4m2, is made from recycled steel and plastic, with a modular assembly that again makes for an easy build. This solution has a much longer lifespan and flexibility in terms of what can be added.

Habitats come together in a layered construction which will include a main planting area, zones to attract bee and butterflies, wet habitats and much more.

Between these two is the mid-sized NatureArk®, which is supplied with the habitat materials required, which means only plants need to be added.

“We want our BNG focused products to be plug and play,” continues Terry, “where it’s simply a matter of assembling the box and adding soil and plants. The same ethos is evident with our SuDS and BNG Unit, which is simply attached to the property’s downpipe and is sufficiently compact to be added to any individual home. Moreover, in addition to the products themselves, we can provide support and guidance to smaller developers in particular on exactly what they’ll need.”

“Aside from the regulatory requirements, there’s a real benefit here for the housebuilder,” concludes Terry. “Not only are you making a statement about your green credentials, you’re also welcoming them to their new home with outdoor features that will enhance the build quality.”

“We want our Biodiversity Net Gain (BNG) focused products to be plug and play where it’s simply a matter of assembling the box and adding soil and plants.”

SPECIAL REPORT: DIVERSITY AND THE SKILLS GAP

PHPD talks to Eve Livett, CEO of the Association of Brickwork Contractors (ABC) about the skills gap and the growing need for diversity in the construction industry

Dive right in How did you get into the construction industry?

I entered construction somewhat by accident. I had a ‘dream’ of being a singer but after many years gigging, I found myself gravitating towards a more stable, reliable career! My first role within the construction environment was working at The Brick Development Association. It was here that I became enveloped with the beauty of brick and the vital role that it plays within the built environment. At that time, the Association of Brickwork Contractors (ABC) was governed by The Brick Development Association, and I remember always thinking about how much potential and sway the organisation could have in its own right, especially in taking the lead in tackling challenges such as skills shortages and the need for more trade apprenticeships. I put forward my thoughts, and these proposals impelled Geoff Irvine and the company directors to offer me the first-ever employed position at the ABC. Ultimately, my job role was to raise the profile of the Association and deliver on my expectations and intentions surrounding training and education.

Why should there be more diversity in the industry?

Studies have shown that construction sites are more productive with women on board, which highlights the significant value of diversity and inclusivity in the trade. Women bring unique perspectives

16 July/August Professional Housebuilder & Property Developer

and approaches to problem-solving, fostering a more collaborative and innovative work environment.

In addition to this, promoting diversity and inclusivity in the construction industry helps address the skills shortage by widening the talent pool. It encourages a more inclusive culture where everyone, regardless of gender, feels valued and respected. This not only boosts morale but also enhances employee retention and attracts new talent to the sector. By embracing diversity, the construction industry can build stronger, more resilient teams that are better equipped to meet the demands of projects.

Why do you think there is such an issue with diversity in the industry?

In recent years, the construction and engineering sectors have witnessed a remarkable surge in the number of young women undertaking apprenticeships – a staggering 366% increase, to be precise.

This statistic represents a significant shift in the traditionally male-dominated landscape of these industries. However, despite this encouraging trend, women still constitute a mere 15% of the current workforce.

One of the primary hurdles faced by women entering construction is the enduring stigma associated with the industry. It has long been viewed as a physically demanding, male-centric

016_PHPD_JUL_AUG24.qxd_Layout 1 28/06/2024 00:00 Page 17

career, with stereotypes often discouraging women from pursuing roles in this sector. Breaking down these misconceptions is essential to creating a more inclusive and diverse industry.

How can we fix this issue and what is the Association of Brickwork Contractors (ABC) doing to tackle it?

To effect real change, it’s vital to move away from this outdated stigma and embrace diversity wholeheartedly. This entails not only fostering a culture of inclusivity within construction companies but also investing in recruitment strategies that actively seek out and welcome women into the workforce. We need to see more companies invest in targeted outreach programmes, apprenticeships, and mentorship opportunities specifically tailored for women. Additionally, creating supportive and inclusive work environments is key to retaining women in construction careers. Providing ongoing training, professional development, and pathways for career advancement are essential components of fostering a diverse and thriving workforce.

Changing perceptions about women in construction requires a concerted effort from all stakeholders including industry leaders, educators and society at large.

By challenging stereotypes and showcasing the achievements of women already making waves in the sector, we can inspire the next generation of female talent to pursue careers in bricklaying and other roles in construction, not just the trades. We must work harder to showcase the diverse roles and progression opportunities available within the industry in order to dispel myths.

The ABC encourages its members to sign up to the Fairness, Inclusion and Respect programme, an industry-wide initiative that supports businesses in the

built environment to meet legal obligations around equality and diversity in order to create a more inclusive sector.

The programme offers training, resources and guidance so that employers can address workplace culture challenges as a way to attract and maintain a more diverse workforce.

What else is the Association doing more broadly at the moment and what are its current goals?

Part of my strategy was to use the ABC and its existing members to trigger significant changes in the way a career in bricklaying has always been publicly perceived by promoting the many fantastic opportunities to young people about available apprenticeships in the sector. Therefore, I worked with many further education establishments and employers to devise robust routes into the industry and review national curriculums against industry requirements. This provoked the thought of establishing a more employer-led training provider working directly in line with its sector, The ABC Assessment Centre which was launched in 2018.

The ABC Assessment Centre currently provides two core services; trade and management qualifications and accredited training for bricklayers. We also make sure that employers are looked after in regard to receiving any grant or funding associated with our training and qualifications. A major part of what we do is supporting students and bridging the gap between education and employment.

This is so important and something I feel hugely passionate about. There are hundreds of students on bricklaying courses in colleges who, unfortunately, never get to set foot on a construction site, or don’t get the chance to interact with employers, which in turn, sadly sees them complete their courses and not move into construction employment. We work really hard to try and combat these barriers where we can.

n an era where sustainability is becoming the cornerstone of the construction industry, the origin of materials can profoundly affect not only the success of projects but also the wellbeing of the broader community and environment.

Assurance and continuity of supply

Global supply chains are notoriously vulnerable to disruptions, as evidenced by the COVID-19 pandemic, the infamous Suez Canal blockage in 2021 and ongoing conflicts in the Middle East and Ukraine.

The recent attacks on ships passing through the Suez Canal resulted in the rerouting of over 100 container ships around southern Africa, tacking on an additional 6,000 nautical miles to the typical journey from Asia. This redirection caused product delivery times to extend by an extra 3 to 4 weeks, accompanied by unforeseen costs, causing container shipping rates to skyrocket by over 300% in just three months.

This persistent uncertainty underscores the inherent risks of relying solely on international supply chains. For residential projects, which often extend over long periods, local manufacturing ensures consistency in product size, colour, and finish, preventing last-minute adjustments and ensuring timely project completion.

Lower environmental impact

Locally manufactured products generally have a significantly lower carbon footprint compared to imported alternatives, mainly due to the reduced transportation distances. Additionally, manufacturing companies in Britain and Ireland adhere to stringent environmental regulations, reflecting the UK and EU’s ambitious commitment to achieving net-zero emissions by 2050.

The environmental advantages of local sourcing are further underscored when considering supply chain disruptions like the Suez Canal blockage. Such incidents result in longer transportation routes, increased fuel consumption, and consequently higher greenhouse gas emissions and ocean pollution. By opting for locally sourced materials, you can mitigate these adverse environmental impacts, contributing to a more sustainable and eco-friendly construction industry.

018_PHPD_JUL_AUG24_Layout 1 28/06/2024 10:32 Page 19

“Utilising locally manufactured products not only reduces carbon emissions associated with transportation but also fosters regional economic growth and resilience.”

High standards, local impact

The UK is renowned for its high manufacturing standards, ensuring that products meet stringent quality criteria. At AG, they undergo regular inspection and auditing and the firms commitment to excellence has earned it multiple accreditations and standards, including BES 6001, ISO 14001, ISO 45001, and ISO 9001. These certifications provide credibility and peace of mind as well as documentation that can help streamline the planning approval process.

Choosing products manufactured within the UK and Ireland benefits both the local economy and community. By supporting local businesses, consumers help create and retain jobs, ensuring more stable employment opportunities. This circulation of money strengthens and builds more resilient local economies, reducing dependence on external markets and fostering long-term sustainability. This collective support enhances economic diversity, community pride, and overall wellbeing.

By embracing locally sourced materials, housebuilders and property developers can ensure a steady supply chain, support local communities, and deliver high-quality, sustainable projects.

The benefits of opting for locally manufactured products extend far beyond immediate project needs, contributing to long-term environmental and economic sustainability.

Reflecting on the importance of sourcing locally, Gordon Best, Regional Director at the Minerals Product Association Northern Ireland (MPANI), emphasises, “Globally, the construction industry is increasingly recognising the importance of sourcing materials that are readily available locally.

Utilising locally manufactured products not only reduces carbon emissions associated with transportation but also fosters regional economic growth and resilience. It’s a win-win for both the environment and the community.”

“The UK is renowned for its high manufacturing standards, ensuring that products meet stringent quality criteria.”

LANDSCAPING & DRAINAGE

Water under the bridge Steve Skeldon, Product Manager at leading plumbing and drainage manufacturer, Wavin, shares his insight on the significance of effective residential rainwater systems in our current climate.

20 July/August Professional Housebuilder & Property Developer

I

n light of the recent news that the UK has experienced its wettest spring since 1986, the importance of rainwater management in housebuilding has never been more critical. The Met Office reported that the UK received 301.7mm of rain this spring, significantly above the seasonal norm.

This unusual weather pattern emphasises the need for robust and efficient rainwater systems to protect homes and infrastructure all year round.

Rising to the challenge

It’s no secret that the UK has been experiencing increasing levels of rainfall annually. This worrying trend, highlighted by the recent recordbreaking spring rainfall, underscores the necessity of investing in robust rainwater gutter systems for new housing developments. The challenge for housebuilders is to specify systems that provide optimal protection while maintaining the aesthetic appeal crucial to attracting buyers.

Effective gutter systems are essential for safeguarding properties against potential water damage, which can lead to structural issues, mould growth and increased maintenance costs. The science behind these systems involves directing rainfall from the building’s roof to an underground drainage system through gutters and drainpipes.

However, the efficacy of this process hinges on the system’s capacity to handle the water volume from the roof, making system specifications a key consideration above ground.

Efficiency in rainwater management

Ensuring a gutter system’s effectiveness requires careful planning and consideration of several key factors. Critical components influencing a system’s capacity to handle the water volume it encounters include the gutter’s flow rate, its layout and the number and placement of drainage outlets.

The building’s architectural style also impacts the gutter installation process. For instance, level or angled gutters may reduce overall capacity compared to straight runs, which can maximise system functionality. By taking these elements into account, housebuilders can select systems that not only meet rainfall demands but also enhance efficiency and longevity.

Housebuilders and developers must also consider local rainfall patterns. Areas prone to heavy rainfall will require higher capacity gutters and downpipes, such as Wavin’s Osma DeepLine, which features a hydrodynamic outlet, to manage the increased water volume effectively. This ensures that homes remain protected even during extreme weather conditions, reducing the risk of water ingress and associated damage.

However, the responsibility for a successful gutter system continues long after the build is completed. Regular inspection and cleaning of gutters and downpipes are crucial to prevent blockages and ensure a system operates efficiently.

Housebuilders should persist with educating homeowners about the significance of these maintenance activities to prolong the life and effectiveness of their rainwater management systems.

020_PHPD_JUL_AUG24.qxd_Layout 1 28/06/2024 00:09 Page 21

Balancing functionality and aesthetics

The aesthetic integration of guttering systems is increasingly significant in modern housebuilding. Homebuyers are not only looking for functionality but also for properties that offer visual appeal. High-quality rainwater systems that blend seamlessly with a building’s design can significantly enhance curb appeal and property value. For example, Wavin’s Osma StormLine range features a classic ogee shape that combines optimum performance with visual appeal. The high-fronted gutter profile conceals the edge of roof tiles and optional hidden hanging brackets, for a sleek, attractive roofline.

Innovative features such as the Flexiclip and unique concealing sockets also make it easier and neater to connect gutters to fittings, ensuring a clean, permanently watertight joint that’s guaranteed to perform when installed correctly.

These features not only improve the system’s functionality but also ensure that the installation does not detract from the overall aesthetic of the property.

The choice of materials for rainwater management systems can also impact both their performance and visual appeal.

Modern formulations of PVC-U, offer durability and a range of colours and finishes, allowing housebuilders to match the system with the building’s design seamlessly. These materials are also resistant to corrosion and UV damage, ensuring longlasting performance and minimal maintenance.

Adapting to changing climate patterns

The recent spring rainfall levels in the UK highlight the importance of effective rainwater management in housebuilding – particularly for those systems collecting water above ground. High-capacity residential guttering and drainage solutions, provide essential protection against the adverse effects of extreme weather patterns and the potential for increased rainfall. By investing in these systems, housebuilders can enhance the resilience of new developments, protecting homes from water damage and future structural issues.

As the UK faces an increasingly wet climate and homeowners brace themselves for a potentially recordbreaking wet summer, the need for robust, efficient and attractive rainwater systems in new housing developments is more urgent than ever.

LANDSCAPING & DRAINAGE

Two birds, one stone Chris Adair, Product Innovation Manager, Marshalls explains why new and upcoming legislation gives housebuilders the opportunity to rethink their biodiversity strategies.

22 July/August Professional Housebuilder & Property Developer

H

ousebuilders have been anticipating the introduction of biodiversity net gain (BNG) for some time, with the approach described by the government as ‘one of the biggest changes to planning regulations for decades’. It became a mandatory requirement in February, but in the run up to the election, BNG was firmly back on the agenda with the leading political parties referring to it in their manifestos, and a variety of related pledges made.

Designed to ensure developments are contributing more positively to wildlife habitats than before, BNG forces developers and their designers to consider the different ways they can make a more significant impact to nature’s recovery. However, there is also a second, similarly pertinent piece of legislation on the horizon which will require the housebuilding industry to think differently when it comes to drainage.

In February, the government said Schedule 3 of the Flood and Water

“For builders looking to step up their sustainability credentials, this two-step shift presents an opportunity.”

Management Act had nudged closer to full adoption. Once complete, it will put Sustainable Drainage Solutions (SUDs) central to the prevention of flooding from storm overflow discharges on new developments.

For builders looking to step up their sustainability credentials, this two-step shift presents an opportunity. Now, housebuilders should reconsider their existing design principles, and instead opt for solutions which meet both requirements simultaneously. Thankfully, a new innovation in rain gardens offers the answer.

Two-step change

BNG and Schedule 3 overlap in terms of their impact on how housebuilders should approach their developments despite being two separate pieces of legislation.

Previously, it was up to each individual developer to decide how much of their development would be dedicated to features that promote biodiversity. Now, it is a legal requirement to achieve at least a 10% increase in BNG from the baseline for each site. That could be through the preservation of wildlife habitats, an increase in the number of green spaces or an improvement in water quality.

Similarly, while there’s been emphasis on the benefits of using SUDs in new housing developments for several years, it has always been at the developer’s discretion. Now, with urbanisation, population increase, and the impact of climate change exposing towns and cities to increased risks of flooding and watercourse pollution, the introduction of Schedule 3 will dictate more about drainage plans than before.

What’s key to ensuring housebuilders can navigate both crucial changes simply and efficiently, are solutions which offer the chance to both reduce the amount of water entering the sewer systems, while also adding natural beauty and biodiversity to a development. This is where a new modular rain garden kerb system, soon to be available from Marshalls, comes in.

022_PHPD_JUL_AUG24_Layout 1 28/06/2024 00:22 Page 23

An innovative solution

Already widely used across public realm and housing developments to provide a flood management system that doubles up as an attractive, biodiverse feature, rain gardens have increased in popularity amongst housing developers in recent years.

Rain gardens use plants and soil to retain and slow the flow of rainwater from surrounding hard surfaces. One way to use the rain garden method is by combining it with a kerb, where water flows into the garden through an inlet in the kerb, is slowed down by a diffuser flag, and is kept at surface level to be absorbed by the soil. This both supports plant life and prevents the water from immediately entering the sewer system.

Currently, housebuilders looking to use rain garden kerbs must use bespoke solutions, taking up valuable resource in the design process and slowing down installation. However, Marshalls has developed an off-the-shelf system comprising three simple elements to make it easier than ever to add rain gardens to a new development.

Combining a left hand inlet, right hand inlet and a complementary diffuser flag, available in a variety of sizes and finishes, the system will create both a time and cost saving on site when compared to cutting or repurposing standard kerbs. And, due to its modular design, the solution will reduce the margin for error usually associated with bespoke and made-to-measure designs, increasing its effectiveness.

Communities of the future

To understand its potential impact on housing developments of the future, Marshalls’ upcoming rain garden kerb has been trialled as part of a sustainable flood resilience plan in Mansfield, the largest project of its kind ever attempted in the country.

As part of the scheme, Mansfield District Council and Nottingham County Council have invested £76million on a range of nature-based solutions to protect

communities from flooding. For context, just £15million has been invested into similar, previous projects spanning the whole of the UK. By the time the project completes in 2025, rain gardens, as well as several other innovative solutions, will have played a role in storing over 58 million litres of surface water run-off, reducing the flood risk for 90,000 people in the area.

Intended to be the blueprint for how to manage flooding in the future, while also making the area a greener place to live, the project is a showcase of the major impact products like the Marshalls rain garden kerb system will have on communities, as we battle to overcome the catastrophic consequences of biodiversity loss and climate change.

A biodiverse, futureproofing strategy for drainage

As more housebuilders come to realise the benefits of rain gardens, they’ll no doubt become a more vital tool in helping achieve the requirements of BNG and Schedule 3 legislation. The true beauty of Marshalls’ rain garden kerb is that it makes it easier than ever to help those working on new developments integrate the solution to their schemes when swift action is required to make longstanding and widespread change to futureproof our communities. As we all attempt to make the world a better place to live, housebuilders now have more tools at their disposal to not only cater for multiple mandatory requirements but also leave a positive lasting legacy.

“Already widely used across public realm and housing developments to provide a flood management system that doubles up as an attractive, biodiverse feature, rain gardens have increased in popularity amongst housing developers in recent years.”

As warnings over the UK’s flood risk becomes increasingly higher on the news agenda, David Fisher, head of geosynthetic sales at Geoworks, explains why housebuilders need to act swiftly to implement geosynthetic solutions to combat the potential damage of more frequent and heavier rainstorms.

David Fisher, head of geosynthetic sales at Geoworks

Holding back the f lood

A

s a nation, we are well aware of the destruction that flooding can wreak on our communities, causing untold damage to people, their livelihoods, and properties.

Flooding is one of the most important climate change challenges we face, as the UK Health Security Agency noted. It found that around 6.1 million people live in floodprone areas, with additional at-risk areas identified due to rising sea levels. Its report said increased flooding will mean that people and properties, health and social care facilities, transport lines and schools, will all become at risk of flooding.

Housebuilders and property developers undoubtedly play a pivotal role in addressing the flood threat. The devastating floods of summer 2007, which damaged 55,000 properties in England and Wales, revealed that twothirds of the damage was due to overwhelmed drains, culverts, and sewers. The Environment Agency report estimated the insured losses at nearly £3 billion, underscoring the significant impact of these professionals in flood prevention.

It is therefore vital to harness creative, sustainability-led solutions – such as sustainable urban drainage systems (SuDS) – to the long-standing problem of surface water drainage. They are a natural remedy that should be a primary consideration in urban planning.

What are sustainable urban drainage systems (SuDS)?

Prompted by the 2007 floods, the SuDS Manual was published to give professional guidance on their planning, design, construction and maintenance.

As many of you may already know, SuD systems are generally accepted to be the most efficient way to manage the flood and pollution risks from urban run-off. They act in an eco-friendly way by mimicking natural water processes, like ponds and wetlands, slowing down the drainage process so that it doesn’t cause problems elsewhere.

The government last year launched a new approach to sustainable drainage to reduce flood risk. Schedule 3 of the Flood and Water Management Act 2010 provides a framework for the widespread adoption of SuDS in new developments in England. It gives local authorities the role of sustainable drainage approval body (SAB), with responsibility for checking compliance and approving their use.

What are the benefits of SuDS?

SuDS combine engineering with a natural approach to reduce flooding, improve water quality, and enhance overall urban environmental sustainability. They support biodiversity targets in the development of green spaces for residents.

The systems are ideal when combined with geosynthetic products

specifically aimed at promoting and prolonging SuDS products.

The key factor is to integrate SuDS at the earliest opportunity in a project.

Planning early and implementing them in the initial design phase saves time and money and prevents future issues, ensuring properties are more resilient.

Which are the best types of SuDS to use?

Often the most efficient and effective method of managing rainwater and run-off is by installing infiltration or attenuation tanks. These act as slow-release reservoirs for surface water run-off.

They can help to improve water quality by filtering and treating the water, removing potential pollutants, and are designed to cause minimal or no longterm detrimental damage.

Non-woven geotextiles – more simply described as protection fleeces – can also be used to protect attenuation tanks and prevent impermeable membranes from being punctured.

Retention ponds can be lined with geomembranes or geosynthetic clay liners (GCLs).

26 July/August Professional Housebuilder & Property Developer

Other popular solutions for the management of surface water also include permeable or porous paving, such as Geoworks new Ecodeck range.

What are attenuation tanks?

The tanks temporarily store excess run-off water before returning it to the normal drainage system in a controlled manner, helping to reduce or even eliminate flooding, erosion and damage. The geosynthetic technology used will ensure that stored water does not escape from the system.

Attenuation tank liners are prefabricated, flexible, welded box liners and lids that are manufactured in a variety of materials to suit different-sized projects. Once the excavation has been prepared, a protective layer of geotextile is carefully placed on the ground, ready for the prefabricated box welded liner to be installed.

The attenuation tank crates, or blocks, are laid in a predetermined pattern, before holes for inlet, outlet and vent pipes are cut to size. All penetrations are sealed to ensure a 100% waterproofing performance. Specialist welding material can also ensure a water-tight seal.

With one of our systems, pipework from the tank can be connected to the upstream or downstream manholes before backfilling, then finally use a geotextile outerwrap to ensure complete protection.

Using SuDS and geosynthetic solutions early in the design process could be a game-changer in the fight against flooding, helping developers meet legislative requirements and creating improved living spaces.

“Housebuilders and property developers undoubtedly play a pivotal role in addressing the flood threat. The devastating floods of summer 2007, which damaged 55,000 properties in England and Wales, revealed that two-thirds of the damage was due to overwhelmed drains, culverts, and sewers.”

Whether you are working on a new build or redeveloping a property, heat pumps are an excellent choice.

But there are some best practices to follow to ensure the best outcomes on your development, says Andy Smith, National Sales Manager at Grant UK.

Beat the heat

W

ith any heat pump installation, the beginning of the process starts with the planning and thorough site surveys and assessments of the property (or plans in the case of new builds) and its heating and hot water requirements. Every home will have different requirements and it is important that installers work closely with their housebuilders and property developers to ensure they specify and install a heat pump system which will fulfil their requirements.

Conducting detailed site surveys and room-by-room heat loss calculations are crucial.

By discussing a property’s heating requirements, this allows for the specification of the appropriate products needed for the system’s design. It is essential to size and install heat emitters correctly and with redevelopments, this may mean replacing the existing heat emitters. All the system pipework must be sized, fitted and lagged properly otherwise this may affect

the wider system’s efficiency. Once the installation is completed, carrying out a comprehensive setup and commissioning of the heat pump and heating system is then paramount.

If you are redeveloping a property and replacing a fossil fuel boiler, it is important to consider that air source heat pump installations often take longer than boiler replacements due to additional installation steps and system checks.

The customer handover is also critical.

After successful installation and commissioning, installers should conduct a thorough handover with the customer, ensuring they understand and are confident in operating their new heating system. With new builds, when the homeowner may not be moving in for several weeks or months after the system has been commissioned, it is worth putting together handover packs that can be left in the property ready to help the homeowners when they first move in.

Preparation

Prior to commencing an installation, the following should be thoroughly assessed: Heat pump location – all heat pumps will make some noise and create a cold air discharge so factor in windows and proximity to living areas when considering

028_PHPD_JUL_AUG24_Layout 1 28/06/2024 00:46 Page 29

the final position of the heat pump. Take neighbouring properties into account as well as the heat pump position when opening doors and windows on the customer's own property.

Where possible, choose a position which is protected from the wind and where the unit will not obstruct access to doors or paths. The orientation of the heat pump should also be considered – to ensure maximum efficiency, ideally a heat pump should be positioned on a warmer side of the property, preferably on a south facing side.

Suitable installation base – an air source heat pump must also be installed on a firm, flat, level surface. The surface on which a heat pump is fitted must be able to support the weight of the heat pump unit and minimise the transmission of noise and vibration. If a suitable surface is not already in place, installers will need to prepare a suitable base for the heat pump prior to installation by either laying a flat trowelled concrete base 150mm thick or by positioning paving slabs on compacted hard core of sufficient depth.

Clearances around the heat pump – suitable clearances must also be in place around the heat pump. These clearances are important because they allow for adequate air flow in and out of the heat pump while also making the unit easy to access for commissioning, servicing and maintenance.

Installation

When it comes to installing an air source heat pump, alongside the heat pump, accessories and core components needed for the system itself, engineers also need to remember the following: Pipework insulation – insulating all internal and external system pipework with a suitable grade of insulation is vitally important. Grant UK supply a through wall insulation kit which includes heavy duty insulation to fit through the wall of the property and around the flexi hoses connected to Aerona³ heat pumps. If all system pipework is not suitably insulated,

this will negatively impact the performance of the heating system.

Electrical wiring – the installation of a heat pump does involve the installation of electrical wiring so the installing engineer needs to be suitably trained and competent to complete these elements of the installation work or a qualified electrician may be required at various stages of the installation process.

Specialist access equipment – if a heat pump is being wall mounted, additional equipment may be required depending on the maximum installation height of the heat pump specified by the manufacturer.

To facilitate safe working, equipment such as scaffolding and suitable ladders may be required. All Grant Aerona³ R32 heat pumps can be wall mounted at a safe height, with the top of the unit no more than two metres above ground level.

“Housebuilders and property developers can access heat pump training, from in person courses to online learning, which will help them to understand specific products, installation and develop their knowledge.”

HEATING, VENTILATION & PLUMBING

Rising to the challenge Ruth MacEachern, Product Manager at EnviroVent, addresses the challenges of integrating mechanical ventilation systems in ever more airtight homes, including Passivhaus properties.

“M

odern buildings are required to be more airtight and energy efficient than ever before to meet Building Regulations requirements and create more sustainable homes. Although airtight buildings can be more comfortable for occupants, effective mechanical ventilation is essential to maintain consistently high levels of indoor air quality and ensure condensation and mould is not allowed to form.

The main purpose of mechanical ventilation systems is to introduce fresh, filtered air and exhaust stale, contaminated air from buildings. These systems filter out pollutants, allergens and odours, improving the overall health and comfort of occupants.

In addition, with the rise of pollutants, such as carbon particulates, in the atmosphere, there has become a greater need for high-grade filtration systems.

Mechanical ventilation systems, particularly those used in Passivhaus buildings, are often equipped with highefficiency filters that can effectively remove airborne particles and maintain a clean and healthy indoor environment.

Energy efficiency and heat recovery

Mechanical ventilation with heat recovery (MVHR) systems can be the answer to making an airtight homes energy efficient, whilst achieving high levels of indoor air quality.

These systems are designed to recover the heat from the outgoing air

30 July/August Professional Housebuilder & Property Developer

and transfer it to the incoming fresh air.

This heat exchange process means MVHR systems can significantly reduce the energy required to heat or cool the incoming air, resulting in lower energy consumption and reduced carbon emissions. Heat recovery systems can typically recover about 73–95% of the heat in exhaust air – they can also significantly improve the energy efficiency of buildings.

Overheating can be mitigated with the summer by-pass function measuring indoor and outdoor temperatures, adjusting the ventilation speed accordingly. However, it is important to firstly consider the main fabric of the building, orientation and shading to avert any potential overheating issues.

While mechanical ventilation systems offer numerous benefits, their integration in airtight homes comes with its own set of challenges. Maintaining the integrity of the building envelope is crucial as any unintended air leakage can compromise the performance of the mechanical ventilation system.

Typically in newly constructed buildings, duct leakage can range from 25-40% (Source: Department of Energy report), which is unacceptable for highperformance buildings like Passivhaus. To address this challenge, it is essential to ensure correct sealing of ductwork, which should minimise leakage to less than 3% of the system's air volume. This requires a combination of effective design, quality installation and rigorous testing to achieve optimal airtightness.

030_PHPD_JUL_AUG24.qxd_Layout 1 28/06/2024 00:50 Page 31

“Maintaining the integrity of the building envelope is crucial as any unintended air leakage can compromise the performance of the mechanical ventilation system.”

Insulation and seals should be inspected to ensure they are intact and there are no gaps or leaks that could compromise the airtightness of the Passivhaus concept.

Carrying out regular checks and maintenance is particularly important with Passivhaus ventilation systems.

Design considerations

Accurate system design and sizing of mechanical ventilation units is critical to their effective operation. A ventilation system must be able to provide an adequate supply of fresh air while maintaining the desired indoor air quality and comfort levels. Factors such as building occupancy, room sizes and ventilation rates need to be carefully considered during the design phase.

Undersized systems can lead to poor indoor air quality, while oversized systems may result in unnecessary energy consumption and increased costs.

Working with a ventilation manufacturer from the design stage can help ensure the right balance for optimal performance.

Commissioning

Commissioning is a vital step in the integration of mechanical ventilation systems to ensure the integrity of airtight homes. At this stage, the installer ensures that the system is operating as per manufacturer’s guidance and meets the design requirements of the build.

Installers will test the system's performance, verify airflow rates and ensure proper control and functionality.

To address the challenges associated with integrating mechanical ventilation systems in airtight homes, performance needs to be optimised. One of the ways this is achieved is through regular maintenance.

Filters play a vital role in removing pollutants and therefore reducing the risk of irritation and respiratory issues. This helps maintain proper airflow distribution and prevents blockages that can hinder the ventilation system’s performance.

Air ducts and components should be inspected periodically and cleaning of units and replacement of filters should be carried out as directed by the manufacturer in order to enhance system efficiency and ensure high levels of air quality.

A professional ventilation maintenance service involves monitoring airflow and humidity and replace any faulty parts. It will ensure that all components are functioning correctly and helps identify potential issues before they become a major problem.

Monitoring performance

Monitoring the performance of the mechanical ventilation system is essential to ensure it operates effectively to eliminate condensation and enhance indoor air quality. Regular checks on airflow rates, pressure differentials and temperature levels can help identify any issues or deviations from the desired performance. This information can then be used to make necessary adjustments or repairs to optimise the system's efficiency. This data is available on some mechanical ventilation systems via an App that forms part of the ventilation system controls, which is especially useful if a property is being managed by a social landlord.

Integration and optimisation

Integrating mechanical ventilation systems in airtight homes, including Passivhaus buildings, presents both challenges and opportunities for the new build market.

Effective ventilation system design can go a long way to address the potential challenges posed by airtightness, with the result being improved indoor air quality, energy efficiency and reduced carbon emissions.

Mechanical ventilation systems play a vital role in enabling airtight buildings to benefit from high levels of indoor air quality for the long term.”

HEATING, VENTILATION & PLUMBING

All under control Will Heinzelmann, Product Director at Passiv UK returns to PHPD and explains why smart controls are the right choice for decarbonising domestic heating.

Will Heinzelmann, Product Director at Passiv UK

W

e know that the UK will have to decarbonise domestic heating to meet 2050 netzero targets and that the most likely technology to move this forward will be heat pumps. In fact, the UK Government is targeting 600,000 heat pump installations a year by 2028. This ambitious figure presents both opportunities and challenges for housebuilders, who will play a crucial role in heat pump adoption.

The National Audit Office (NAO), the independent public spending watchdog, has reported slow progress in decarbonising the UK’s heating. So, what’s the hold-up? Well, there are a number of barriers to achieving the government’s ambitious installation figures, including complex installations, high electricity costs, and the difficulties for consumers in adapting to an unfamiliar heating system.

Installing smart controls alongside heat pumps can help to address many of these challenges. These smart solutions can simplify the currently complex heating system controls for the consumer and offer them opportunities to earn additional income by providing flexibility to the electricity grid, both of which provide reassurance to housebuilders and their customers.

Get paid for supporting the grid

Heat pumps pose a challenge to grid security. They are expected to increase the UK’s peak electricity demand from about 50GW to 130GW – an increase of

32 July/August Professional Housebuilder & Property Developer

over 150%. Heat pumps typically consume most power during cold winter evenings – times when demand is high and there’s no sun in the sky for solar panels to utilise.

However, they also offer households a great opportunity to earn extra cash, with a unique potential for flexible operation.

Heat itself is an energy source that can be effectively stored and, if carefully managed, this doesn’t need to result in a cold home.

To ensure that the electricity supply remains secure, heat pumps will have to form part of a smart, flexible energy system and be capable of adjusting their operation in response to national electricity requirements. This can all be enabled through smart, connected controls. These new smart control solutions are designed to get the most out of heat pumps and make transitioning to a heat pump easier than ever. Smart, automated controls are also already helping householders earn money with their heat pumps.

The continued uptake of domestic flexibility provides an exciting new opportunity for heat pump owners.

Demand Side Response will become essential for the stability of our energy system as it increasingly relies on renewable sources of electricity. A smart, two-way energy system allows customers to earn money through the devices they use. High-power devices, such as heat pumps, offer the most valuable source of flexibility, but to do so, they need to be operated in a smart, connected way.

032_PHPD_JUL_AUG24_Layout 1 28/06/2024 12:10 Page 33

“For housebuilders and developers, smart controls make properties even more attractive; they offer a solution for sustainable housing with easy-to-use heating controls that allow their customers to earn money through the grid.”

Simplifying controls

Current heat pump controls are not easy to use. One study found that when presented with a typical heat pump thermostat, just 23% of people can set a heating schedule – one of the most basic and vital functions of any heating controller. Why is this? Partly, it’s because most heat pump controls haven’t been designed for controlling heat pumps. Heat pump manufacturers generally fall into two categories – they are either air conditioning manufacturers or boiler manufacturers who now make heat pumps. And, unfortunately, they tend to use the same controls for their heat pumps that they use for their air conditioners or boilers. There’s a reason the average heat pump controller looks like the air conditioning control panel you find in a hotel room and, if you’ve ever tried to use one of those, you’ll understand why current controls are so poor!

The latest generation of smart controls are designed to be simple to install and commission for an installer, as well as being really easy for a homeowner to use. If heat pumps are going to be the main solution for decarbonising the UK’s heating, they need to work for everyone and that means having simpler controls. Smart heat pump controls shouldn’t only be for the tech-savvy. They need to be accessible, easy to use, and suitable for anyone who has a heat pump.

For housebuilders and developers, smart controls make properties even more attractive; they offer a solution for sustainable housing with easy-to-use heating controls that allow their customers to earn money through the grid. The future of homebuilding is not just green, but smart and profitable.

By embracing smart controls, we can overcome the barriers to widespread heat pump adoption and ensure a smooth transition to a more sustainable and energy-efficient future.

Mixergy iHP X is the ideal hot water solution for sustainable homes

34 July/August Professional Housebuilder & Property Developer

In the mix

T

he Mixergy iHP X is an integrated heat pump cylinder that leverages Mixergy’s patented adaptive water heating technology. This product offers a cost-effective and convenient solution for housebuilders and developers aiming to meet the Future Homes Standard. It enhances the appeal of new homes, providing a smart hot water solution to buyers who are increasingly concerned about rising energy bills and their carbon footprint.

According to the manufacturer, it is three times more efficient and can save upwards of five tonnes of carbon per unit,

compared to a conventional cylinder. It is also described as ‘best in class’ for energy performance because the plate heat exchanger inside the heat pump unit achieves exceptional heat transfer. Unlike traditional integrated heat pump cylinders that heat water from the bottom up, the iHP X heats from the top down, delivering usable hot water in under 30 minutes.

This allows the unit to be up to a third smaller, making it easier to position and install in homes.

One of the significant advantages of the unit is its modular design. The heat pump and cylinder components can be separated

034_PHPD_JUL_AUG24.qxd_Layout 1 28/06/2024 00:59 Page 35

“The iHP X was installed in a cupboard that didn’t require soundproofing and has a standard single layered door.” to make the system lighter and easier to transport, install, and maintain. Each part is accessible, supporting the ‘right to repair’ ethos by allowing for individual servicing and replacement. This design extends the product’s lifecycle and allow for substantial warranties – 25 years for the cylinder and five years for the heat pump unit.

Control and optimisation is simplified through the Mixergy app, which allows users to programme the unit to take advantage of smart electricity tariffs and to integrate with solar PV systems for using free electricity. The system's flexibility and compatibility with various energy sources make it an ideal solution for sustainable living.

A practical example of the technology in action is the renovation undertaken by Laurence Haslop, managing director of Cambridge housebuilder and developer Develory. Haslop has transformed a 1970s bungalow, which originally had oil central heating, into a modern, efficient home. He chose the Mixergy iHP X for its efficiency and ease of integration with other sustainable technologies, such as infrared electric heating, solar PV, and planned battery storage.

Haslop, who has a strong background of utilising innovative technologies, found the Mixergy cylinder efficient and easy to install. Even without prior experience of the product, the installation was straightforward: “We installed the integrated heat pump cylinder in a cupboard downstairs, but because it’s modular, it could have easily been located upstairs. The installation only took a day – with more experience, I’m sure we could install it even quicker.”

Heating engineers only need their G3 Unvented certificate. As the refrigerant is pre-gassed and completely sealed within the heat pump module, F-gas certification is not required, opening up the skill base for who can install this product.

Haslop continues: “Develory is focused on providing the latest sustainable technologies that do not compromise the durability of a building.

What differentiates us is innovation and how we can add technology to a home or commercial building while making it good value and robust. Every scenario is different and needs to be considered individually. There is never a one size fits all solution. We use the materials and the technologies available to us as a tool to build the best solutions for the clients’ needs.

“The performance aligns well with the needs of small flats and larger houses alike, especially those aiming for the most sustainable solutions. The ability to heat water quickly and efficiently, combined with compatibility with smart tariffs and solar panels, makes it a really versatile choice. The householder can control how much water to heat based on their needs, optimising energy use and costs.”

Another important consideration was noise. The iHP X was installed in a cupboard that didn’t require soundproofing and has a standard single layered door. Haslop says: “It’s very quiet – which works for us!”.

The system’s ducting was designed to ensure optimal performance, with air in and air out ducts terminating on different sides of the building while ensuring the runs are not unnecessarily long or complicated, to achieve the highest Coefficient of Performance (CoP) of up to 3.4.

“We have used technologies in this house that our company wants to test and learn from before installing in our clients’ developments. The Mixergy iHP X is a promising solution and we are happy that it will fit in various scenarios, depending on what we want to do with it, and I would recommend it to other housebuilders. I am excited to see how the product develops!” he concludes.

Laurence Haslop, managing director of Cambridge housebuilder and developer Develory

“We installed the integrated heat pump cylinder in a cupboard downstairs, but because it’s modular, it could have easily been located upstairs. The installation only took a day – with more experience, I’m sure we could install it even quicker.”

Ready for the future

PHPD talks to DiscreteHeat about ThermaSkirt, its radiant heating system that looks just like a traditional skirting board

36 July/August Professional Housebuilder & Property Developer

H

ousebuilders are constantly looking for innovative products that will help them meet the latest sustainability requirements of the Building Regulations while meeting the energy efficiency and running cost reductions demanded by homebuyers – all while ensuring the homes they offer look fantastic and the technology they have is effective and simple to use.

ThermaSkirt, made in the UK by DiscreteHeat, is an energy efficient infrared radiant heating system, cleverly designed to look like a traditional skirting board. Easy to clean and extremely strong, it is made of aluminium, so once

hot water enters the system, it works immediately, transferring the heat to the room like one large 360° radiator. It can work with any heating system, whether that’s a gas boiler, heat pump or electric heating, and can be controlled just like conventional radiators, using thermostats and timers or smart controls.

One of the many benefits of ThermaSkirt is its flexibility. It can be installed throughout the home, or alternatively, if underfloor heating is being installed on the ground floor during construction, ThermaSkirt can be fitted in the upper floors instead of, or in addition to, radiators. This is especially useful as part of a heat pump heating system, as ThermaSkirt replaces the need for oversized, low temperature radiators.

Laura Hughes-Jones, Sales and Marketing Coordinator at Lancashirebased Kingswood Homes, explains how the company is offering ThermaSkirt as an option in all its new homes. “ThermaSkirt is an optional upgrade in all our house types, which range from three to six bedrooms. There’s a choice of adding it to the whole home or by floor.

“The feedback we’ve received is that customers love the way it makes each room look clean and uncluttered. It allows them to use wall space more practically and be even more flexible with where

036_PHPD_JUL_AUG24_Layout 1 28/06/2024 01:02 Page 37

their furniture can be placed without blocking any heat. There are different heights, styles and colours of skirting to choose from, to suit their preferred style which is another bonus.

“At the moment, Kingswood Homes come with a gas fired combi or system boiler, but ThermaSkirt can work with any heating system and is much more energy efficient than regular radiators. It also spreads the heat across the room, rather than it all coming from a single concentrated source, like a radiator.

“How easy was it to install? Very! It can be completed in a day. We have even retrofitted it in our Ribchester 5 show home at Green Hills Homestead, near Blackburn. And we’ve had a number of future customers enquiring about the product and showing interest for when they reserve their homes in the coming weeks and months,” concludes Laura.

Kingswood Homes is different from most housebuilders because it offers flexible floor plans, putting customers in charge of their internal layout. The ‘Shape your home’ concept means they can choose to have fully open plan living downstairs or they may prefer a separate lounge and dining room, or a home office or playroom. And they can choose to add or remove bedrooms and add additional en-suites.

ThermaSkirt is the perfect solution for this flexible approach to providing the space the homeowner requires. It is also a good fit with the other high-quality technologies that Kingswood Homes offers, so their customers can personalise their homes even further. These include smart heating controls, video doorbells, EV chargers and integrated appliances.

Ethan Wadsworth, Sales and Marketing Director at DiscreteHeat, says: “ThermaSkirt is available pre-cut and fits together easily. Because it combines fitting and painting the skirting with installing the heating, the installation time and costs are reduced. We are happy to work with builders, developers and contractors and will provide on-site training and technical support as required.

“ThermaSkirt carries ISO 9001 and is CE marked. We are proud to design and make ThermaSkirt in the UK to EN standards from up to 98% recycled aluminium, so as well as saving homeowners money on their energy bills, we’re doing our bit for the environment, too.”

“Because it combines fitting and painting the skirting with installing the heating, the installation time and costs are reduced. We are happy to work with builders, developers and contractors and will provide onsite training and technical support as required.”

HEATING, VENTILATION & PLUMBING

Oliver Baker, CEO of Ambion Heating, makes his case as to why a diverse approach to heating technology is critical for the success of the Future Homes Standard.

Oliver Baker, CEO of Ambion Heating

Hedge Your Bets N ext year, the Future Homes Standard (FHS) will come into effect in England. Its purpose is to ensure that newly built houses are future-proofed with low-carbon heating and leading levels of energy efficiency to help the UK meet its legally binding net zero target by 2050. To effectively achieve its purpose, the FHS must take a diverse approach to heating. Without it, the UK may struggle to reach its emissions target on time.

Residential properties in the UK contribute to approximately 17% of the country's carbon emissions due to the majority of properties being heated with natural gas. To transition homes away from fossil fuels, the new standard heavily focuses on heat pumps or heat networks to reduce emissions in future buildings, alongside improved energy efficiency measures. While many properties have already had heat pumps installed, the UK has just 412 heat pumps per 100,000 people, significantly behind its European neighbours.

Eggs in multiple low-carbon baskets

With a lower-than-expected uptake for heat pumps over the last two years for existing properties, can this technology be relied on to meet the ambitions of the FHS? Heat pumps have a vital role to play in the future of heat, but they shouldn’t be the only consideration around low-carbon heating. Even with world-leading levels of energy efficiency, heat pumps don’t fully address the high cost of energy and have large upfront installation costs.

Space is also another factor to bear in mind for property developers and housebuilders. The FHS will cover all homes, including urban and social housing, for which space is a key aspect.

Of the current number of heat pumps already installed, 74% were in a rural location and for typically larger homes, with an average of four bedrooms. For properties in urban areas, where space is

38 July/August Professional Housebuilder & Property Developer

limited, heat pumps may not be the most suitable solution, and heat networks offer little control for the occupants to change energy suppliers.

Benefits of infrared heating panels

Taking all this into account, one piece of the FHS puzzle should include low-carbon infrared heating panels. These are ideal for smaller homes, like flats, with no barriers around limited installation space.

Infrared heating is well positioned to overcome the challenges of traditional convection systems, as well as the environmental concerns of gas heating.

Infrared heat works like the sun, without any harmful rays. The fabric of the building and the materials within a room absorb and store the infrared waves, making it easier to maintain an ambient temperature for longer.

Installation is quick, easy and hasslefree, as no pipework or radiators are needed. Any qualified electrician can install infrared panels, and installation costs are half that of a heat pump. Infrared heating panels, when paired with Ambion’s unique control system, can also dramatically reduce energy usage and the unit cost of electricity by maintaining a room’s temperature within 0.1°C of its target, 24 hours a day. This flat demand profile means there are no morning or evening energy spikes in usage, reducing costs for energy consumers as well as developers. Low-carbon heat panels also provide an attractive low-carbon solution, especially when combined with solar PV and battery storage.

By taking advantage of all the low-carbon heating technologies currently available, all future homes have the potential to be net zero while being cost-effective.
