A new piece of research from the NHBC Foundation – Future Homes - Avoiding unintended consequences – aims to bring more knowledge into the sector, not only on how to deliver the aims of the new standard, but also to help unlock the potential it brings.Identifying three key areas – heating, ventilation and design – the resource is designed to bring forward further discussions on the topic. You can read more on page 8. In the meantime we have just had amendments to Part L of the Building Regulations, with new requirements coming into effect in June 2022. Although the true impact of these changes will become clearer over time, in this issue we hear from a number of manufacturers with their take on the situation. On page 16 we hear how the changes may spur housebuilders to take a look at their brick selection, while on page 18 there is information on how Part L may drive a reconsideration of insulation options. We also hear how ventilation may be affected, with a possible shift towards a systems approach. Find out more on page 31.

Most in the sector will be aware of the long held aim to gradually reduce carbon emissions associated with housing. In the new homes sector this has, in part, been implemented via the Building Regulations, and in particular Part L, used to encourage and require construction outcomes which seek to bring energy saving and emissions reductions to the fore.

Although challenges remain as we head towards Net Zero, the recent changes to Part L and the forthcoming Future Homes Standard provide a clear indication of how new homes must adapt to help reduce carbon emissions and lower energy bills. from PHPD visit
While manufacturers continue to bring new materials and technologies to the market to help meet the requirements, many remain unsure of the implications and how to meet the challenges.
The UK’s housing stock needs to be more energy efficient and all in the sector have a part to play. Not only is it the sustainable thing to do, but there is also a growing business case emerging with some housebuilders already specifying items such as solar PV panels, air source heat pumps, underfloor heating, and EV charging points into new homes – seeking to target any growing interest in sustainability amongst house buyers.
And just a few years ahead is the Future Homes Standard, due to come into effect in 2025, and with it new homes that have low carbon emissions and low energy bills.

Supply shortages and material costs remain the number one challenge for housebuilders and developers in property consultancy Knight Frank’s Q1 2022 survey. The quarterly UK housebuilder survey and land index canvassed 50 volume and SME housebuilders across the country, to provide a snapshot of industry sentiment.Landavailability remains another important issue for respondents. 86% said available land market supply was either limited (50%) or very limited (36%). Only 14% said the availability of land was adequate.

New home completions return to pre-pandemic levels, reports NHBC New data released by NHBC reveals that new home completions have returned to pre-pandemic levels. A total of 40,289 were completed in Q2 2022, up 16% on Q2 2021. The quarter also saw an increase in the number of new home registrations to 66,855, up by 45%. The organisation says this uplift is in part due to builders seeking to minimise the cost impact of energy efficiency regulations introduced in June.

Where a customer doesn’t have a robust exit plan in place, they risk being forced to move onto another short-term property loan, with associated fees. And that can be really costly. Of course, there are inevitable bumps in the road with development projects and you can’t account for them all.

FINANCE
But short-term finance becomes prohibitively expensive when it’s needed for longer than expected. That’s why lenders and borrowers need to work together to nail down their timescales and exit strategy.
What lenders want The best bridging and development finance lenders have one goal in mind –helping you create wealth through property. That’s why developers should be careful about partnering with funders that aren’t asking questions about your exit strategy from the off.
How to exit There’s no best way to redeem your short-term property finance – it depends entirely on your particular project and futureYourplans.exit strategy could be selling the property, renting it out and remortgaging onto a long-term buy-tolet mortgage, or moving onto a longerterm loan with the same lender using a bridge-to-term product. Having a clear goal and a plan to get there is what’s essential.
What happens at the end of a bridging loan is one of the most important parts of the whole process. Both the borrower and lender need a clear understanding of the exit strategy from the off. Not only will it mean you’re better prepared to plan and deliver your property project, it also boosts your chance of securing funding swiftly.
The good news is that this extra scrutiny shouldn’t mean it takes longer to secure bridging funding. In fact, it’s often quicker. If your project makes sense and the lender can see that your exit is realistic, you’ll get a bridging loan offer without delay or requests for further information.
When a lender insists on a clear exit plan, it’s because they want your property project to succeed, for you and them. They’ll start by checking your schedule of works and costings to make sure they’re realistic. At the moment you can expect to be asked to include a generous contingency of at least 10%, given rising prices. And they’ll want to know how you plan to repay the loan. Having all of this ready before you apply for bridging finance will boost your chance of success.
Bridging loans
Ongoing support
The focus on exit strategy doesn’t (and shouldn’t) stop when you drawdown yourThefunds.best lenders are proactive about checking progress throughout the loan term. They want to ensure things are on track, help where they can, share expertise and offer amendments or extensions if needed. Consider it a red flag if a bridging lender isn't focused on your exit strategy. Your funding partner should be thorough when assessing your property project, for their sake as well as yours.

Building Regulations Part L? Part L is split into numerous documents covering multiple areas, however, here is the relevant document to this topic: Approved Document Part L1A This covers the requirements for new homes and their energy efficiency, along with individuals responsible for ensuring that building work and homes remain compliant with the regulations within the document. U-values, fabric efficiency and CO2 emissions U-values are used to measure how effective the fabric of a home is at preventing heat transmitting from outside to inside and vice versa. The lower the U-value score, the better, as this means there is less heat transmitting through the house. As part of the Future Homes and Buildings Standard, measurement of U-values is to become required and much more stringent. The measurements are detailed in the table. a brick switch?
requirements of the changes due to the sustainability and carbon saving benefits.
F rom the 15th June 2022, changes were made to Approved Document Part L Building Regulations as part of the Government’s ongoing progression towards its net zero goals, including that of delivering zero carbon ready homes by 2025. Understanding the changes to these regulations and how they impact housebuilders is a key consideration to remain compliant and working to best practices. Here, Kevin Cafferty, Commercial Director for Marshalls Bricks & Masonry explores the changes to Approved Document Part L in a little more detail, along with how a switch to concrete bricks can help housebuilders meet the
Marshalls outline why the recent changes to the building regulations could mean it is a good time to consider switching to concrete bricks.
As part of the updated regulations that centre on fabric efficiency, the housebuilder must ensure that every new home produces 31% less CO2 emissions than in the 2013 version of Approved Document Part L. Essentially, this is viewed as a step towards the new Future Homes and Buildings Standard set to be introduced in 2025. This new Future Homes and Buildings Standard is expected to state that new homes must produce 75-80% less carbon emissions than homes do currently under the Alongsideregulations.designing homes for low energy consumption to achieve these reductions, there must also be a key focus placed on the materials used in construction.
Moreover, one considerable and immediate reduction in embedded CO2 could be made simply by the very bricks that are used. Here is where concrete bricks offer many advantages. Being cured and not fired in a kiln, results in a massive reduction in heat energy and fossil fuels required throughout the process. Plus, it also means that the bricks will continually absorb CO2 throughout their lifetime. The total lifetime reduction in CO2 derived from specifying concrete bricks, over the more traditional type of brick on the market, is 49.1%. If all UK housebuilders switched to concrete bricks for all homes built in a single year, the lifetime CO2 reduction would be the equivalent of removing 300,000 cars from the roads or reducing 500,000 transatlantic flight planes.
There is no doubt that the concrete brick manufacturing and technology processes have come a long way and are constantly being developed. With greater dimensional accuracy, ensuring a more consistent size and shape between individual bricks and different batches, as well as complete colour stability throughout its lifetime, concrete certainly ticks a lot of boxes. In recent on-site trials, Marshalls was keen to test their latest concrete facing bricks with professional bricklayers and the verdict was overwhelmingly positive in the weight, productivity and ease of cutting and shaping using hand tools.

Switching to concrete bricks is a huge step toward achieving carbon neutrality and should be a key priority for housebuilders moving forward.
InsulationSelecting
18 September Professional Housebuilder & Property Developer
It’s important to note that copying the notional dwelling is unlikely to be the best route to compliance for housebuilders. Here, I’ll build on that showing how you can use trusted insulation solutions to achieve compliance whatever your priorities.
C hanges to Approved Document L (Part L) came into force in June. By now, most housebuilders will be familiar with the headline figure – a 31% reduction in carbon emissions for all new build homes delivered by fabric improvements, low and zero carbon technologies.
James Hulbert, Head of Housing at Knauf Insulation, explains how a ofbenefitcomplianceLApprovedapproachbespoketoDocument(England)2021willhousebuildersallsizes.
Theoretically, the lower the thermal conductivity (lambda value) of an insulation material, the less heat is transferred increasing energy efficiency. But some insulation materials are harder to install correctly than others, leading to unintended air gaps that allow heat to escape. This means a lower lambda (better performing) material may lose more heat than one with a higher lambda (lesser performing) material.
The transition is swift. After 15th June 2023, any undeveloped plots (not sites) must comply even if planning permission was applied for or obtained under the old regulations. So, there’s not much time to adapt new home designs to accommodate the changes.
To get the specification right, it’s critical to consider how the insulation you choose performs in the real world. Not just thermal performance, but fire safety, acoustics and sustainability too: Mineral Wool insulation scores highly against all of these requirements. Real performance This refers to a product or system’s ability to deliver it’s intended performance once it has been installed. So, what do I mean by real performance in relation to energy efficiency? Quite simply, that the finished building will achieve its target level of energy efficiency – crucial for Part L compliance.
The optimal route to compliance How you find the most favourable path to compliance for your developments depends entirely on your needs. Cost will clearly continue to be the primary consideration for most housebuilders, but there are other factors likely to influence yourFordecision-making.example,some developers will place emphasis on the ‘simplest’ compliance solution. One based on trusted technologies and solutions where they are familiar with procurement, installation and risk management. Others will prioritise availability in their compliance approach, considering which low-carbon technologies are likely to be available in the quantities and at the lead times they need. Others still may focus on futureproofing, preferring a recipe that can be readily upgraded to meet changing standards in the future. These and other factors will determine which path you take. But while every route requires a ‘fabric first’ approach, the nature of that fabric is up to you.
For example, minor imperfections in the substrate, such as mortar snots may prevent a rigid insulation from sitting flush against the building fabric, creating gaps. This could also lead to difficulties in complying with the Building Regulations England Part L (BREL) report because the photographic evidence will not show the required quality standards for installation.
Mineral Wool adapts to slight imperfections in the substrate and butts together eliminating gaps, ensuring it delivers its intended performance.

After thermal performance, one of the most compelling reasons for using Mineral Wool insulation is to minimise the risk of fire. Combustible materials are already banned in the external walls of certain types of buildings over 18m in England and Wales (11m in Scotland). But where fire safety is concerned why take the risk? Mineral Wool is noncombustible so will not add to the development or spread of fire should it occur, making it the safest option in all types of home, regardless of height. Mineral Wool is also highly sound absorbent so helps to reduce noise, which is essential in low mass structures such as timber frame constructions. When it comes to sustainability, embodied carbon must be considered alongside operational carbon. The RIBA has already introduced targets as part of its 2030 Climate Challenge, while many housebuilders and their customers have made their climatehelpcommitmentsowntoaddressthecrisis.So, it makes sense to specify products that are low in embodied carbon wherever possible. Glass Mineral Wool is a good choice because certain products have the lowest levels of embodied carbon of any mainstream insulation material. The best way to check a product’s carbon footprint is through the manufacturer’s Environmental Product Declarations (EPDs). They are verified by an independent third party, comply with European standard EN 15804 and list the product’s environmental performance across its lifecycle.

Construction companies, house builders and roofing contractors often come to us with a clear idea of what they need, based on their own experience and an architect’s drawing.

Charlie Cannon, Design Manager at Beesley & Fildes’ engineered timber department, looks at some of the considerations when selecting the most appropriate timbers for roofing projects.
ROOFING & CLADDING
Professional Housebuilder & Property Developer
The right choices To a degree, the choice between i-beams and posi-joists is often based on personal preference and experience but, as trends in house design evolve, it’s important to understand the different advantages and limitations of each type of timber. Our design software enables us to create an optimised design that takes into account the structural loading, required spans and roof design so that we can present customers with the most appropriate and cost effective solution.
But, as a service-oriented builder’s merchant, it’s not our job to simply give them what they’ve asked for; we also advise them and add value wherever possible with our own experience and design expertise. In that way, we can help them make informed decisions that could enable them to reduce costs, simplify the installation and achieve an improved outcome for their project.
It is an approach that enables us to elevate commodity products – the i-beams that we cut to size on site and the posijoists that we manufacture on site – and help customers make the right choices for their project and their business.
The enhanced load bearing and structural strength provided by posi-joists makes them an ideal choice for larger roofs and, in particular, for roofs that feature larger spans. Increasingly, we are finding that loft spaces are being used as open plan accommodation and posi-joists enable the required spans to be achieved with smaller timber widths, working within the loading limits of the stricture and avoiding any compromise to ceiling heights in the loft space or the floor below.
In basic terms, i-beams may be less expensive but the width and/or number of i-beams required to achieve larger spans can often lead to increased design and installation complexity, installation costs and programme length. Helping the customer see the bigger picture in terms of the installed costs, programme and risk management is not always straightforward, so it’s important that we provide a clear business case for the solution we’re suggesting, rather than allowing our advice to seem like an upsell.
The open structure of posi-joists also means that wiring can easily be fed through the joists, aiding speed of installation as compared to i-beams,
i-beams & posi-joists: select the right solution
22 September Professional Housebuilder & Property Developer
One of the challenges we sometimes face is customers who modify timbers for the roofing installation to make them fit as the installation involves on site, as opposed to faithfully following the CAD drawings for the design. Sometimes this is due to incorrect measurements being supplied or site measurements differing from design measurements. Sometimes it is because an incorrect component has been used earlier in the installation and the builder is working around what is required with what is available. Part of our service, therefore, involves ensuring the customer understands they have everything they need and we make it clear that our team is available for trouble shooting advice throughout the project if they have a question after they have received their timbers and metalwork. We always encourage them to call us before they modify anything, so that we can help them to install the roof according to the design. This is what we mean by an end-to-end service, from design through to finished installation.
“it’s important to understand the different advantages and limitations of each type of timber” where holes need to be drilled in the correct locations. Not only is creating apertures for building services a timeconsuming addition to the programme, but it can also affect the integrity of the ibeam, which is another key consideration when customers are selecting the best approach for their project.
Importantly, a simplified, easier to install design with all components provided as a complete package not only offers customers cost advantages, it also de-risks their project. Simplification means fewer opportunities for error and detailed drawings provide a fully itemised plan for the installation, aligned to every item of timber and metalwork supplied. Moreover, because everything is supplied by Beesley & Fildes using dimensions supplied by the customer, they have complete accountability for both the design and the delivered roof components, including any trusses included in the design and supplied by us.
Reducing risk By using our design service, Beesley & Fildes customers are able to see how the design will be installed. And, because we supply a complete solution with all fixings and accessories included in the drawings and 3D render, it’s easy for customers to appreciate the installation advantages that could result in time and labour cost savings.

ROOFING & CLADDING
A full roof system approach ensures every property’s roof is fully compatible with current regulations, including fire safety, and reduces the risk of inferior product substitution that can compromise roof performance over the long-term.
Government statistics show fire services attended over 150,000 fire-related incidents in the latest 12-month period for which figures are available.* Of this number, approximately 40,000 were in homes or primary dwellings, highlighting the ongoing danger fires in home spaces – including the roof –continue to present to lives and property.
Fire risk Fire outbreaks in roof spaces contribute to c.40,000 house fires occurring in the UK each year. A critical part of fire protection when a roof is compartmentalised between adjoining homes is the role of a fire barrier. This is viewed by experts as an integral safety feature that can prevent the spread of flames and smoke between properties during a fire incident. In terraced or semidetached properties, this increases the risk that fire could spread rapidly through roof voids from one home to the next. Fire stopping is commonly achieved with a flexible mineral fibre quilt or sock, but a potential fire passage still exists at the line of the roofing battens, above the rafters, which can span across the junction between properties. In addition, standard details, such as spandrel panels in timber frame construction, may be used to satisfy fire separating requirements, but do not provide fire stopping to the underside of the roof covering. Whilst there are some fire barrier products available to close this gap, industry feedback from contractors suggests that these can be bulky and difficult to install in line with the roof tiles, especially when using deep profiled tiles.
Building regulations in the UK currently require that all new homes are built with robust fire protection measures in place to not only delay the spread of fire, but also allow time for escape.

As such, housebuilders need to ensure roofing specifications for new homes take an integrated approach; that can add value through a combination of a fully integrated roof system that also includes a method of averting the danger of fire starting in roof spaces.
Stuart Nicholson, Roof Systems Director at Marley, explores the full roof system approach and outlines some of the key considerations.
Roof defence In order to support housebuilders further enhance safety, Marley’s Roof Defence fire barrier offers a simple to install and fully fire protective solution that provides extra security and fire resistance performance up to 60 minutes for extra peace of mind.
The Roof Defence fire barrier features two strips of intumescent material bonded at 90 degrees, with an inverted T design, which is installed under tiles and between roof battens to close all gaps in the event of fire. Whereas some other systems are rigid, Roof Defence is flexible, lightweight and is supplied on a roll, so it can easily be taken onto a roof and rolled out over the
A full roof system For ultimate peace of mind, housebuilders should look to specify a complete solution, such as the full Marley roof system. Tried and tested to work together seamlessly, a full roof system includes JB Red battens, underlay, clay or concrete tiles, fixings, accessories, fire barriers and optional sustainable energy generation with integrated solar panels – and the complete system comes with the reassurance of a 15-year warranty.
For more information, or advice, please go to www.rdr.link/dah016 party wall – helping contractors to deliver a satisfactory fire prevention solution.
By taking a considered technical view about integrated roof solutions, including fire protection measures, housebuilders can be confident in the knowledge that the full roof system specified will stand the test of time, deliver long-term lifecycle cost efficiencies, and ensure homeowner safety in the event of a fire.
When activated by heat, the inverted T intumescent seal expands, filling the space between roofing battens and sealing all spaces under the tiles, slates, and other roofing elements. It satisfies all regulatory fire testing requirements and fills every void from the party wall to the bottom tile, meaning smoke and fire cannot pass through.
Other challenges found when using more traditional methods of fire protection have seen compressed mineral fibre options affect the way the roof covering is fitted. This is because, to be securely fixed, the projecting nibs on the underside of tiles must have space to hook on the rear face of the roofing batten. A compressed mineral fibre quilt, or sock, occupying this space can interfere with this. It can also block important ventilation paths on large, compartmentalised roofs, causing additional ventilation problems.

Clearance However, Roof Defence ensures clearance until activated by the heat of a fire, so it does not affect the fit of the roof covering or block ventilation. The double intumescent strip and inverted T design also make it much more effective at filling both horizontal and vertical spaces.
he arrival of the low temperature heating system has brought with it perhaps understandable questions to which specifiers, architects and housing designers want answers. Can we still use products we use now with traditional boiler driven heating systems if the heat source is a heat pump? Is there anything we need to consider that we take for granted nowadays?

In new build housing, using a heat pump-based solution is a relatively simple solution. The heating system can be designed into the home at the outset so you know the parameters in which the heating system has to operate – the method of construction, the size of the rooms, the number, type and size of doors and windows – so the heat loss calculations can be done up front and radiators sized accordingly.
The development of lower temperature heating systems, utilising renewable heating appliances such as air source heat pumps, has given rise to a number of questions including, where do components we have got to know and love over the years fit into the future of heating? Stelrad Radiators has responded forcefully to those people who claim, for example, that underfloor heating is the only or ‘best’ solution for heat pump installations.

Well understood More than 90% of all heating systems in the UK currently rely on radiators to share the heat around the home. Remember radiators are poorly named. Most radiators are actually convectors – there is a small amount of radiant heat from the radiator but more than 80% of the heat is convected heat – drawn up behind the radiator where the air passes over the metal surfaces of the radiator and heats the air in the room.
The key to radiators operating well in any situation is to size them properly at the outset, which involves accurately working out heat loss calculations to achieve the necessary number of BTUs required to provide comfort heating in each room and to select a radiator can provide that level of heating.
WANT TO KNOW MORE? For more information please go to www.rdr.link/dah017
In replacement heating systems for older properties there are additional issues. It’s a fact that simply replacing a boiler with a heat pump will usually see the existing radiators unable to provide the levels of heat needed in a home. So what is the solution – one that is cost effective and straightforward? Do we need to ditch radiators altogether and look for alternatives?
The simple answer is no. Radiators will work well with heat pumps, but you will need to increase the size of the radiators to provide a larger metal surface area to heat the air in the room to the level required to provide comfort heating. This need not involve unsightly radiators – for one, modern radiators are aesthetically far more attractive anyway, but there are other solutions too. You can achieve the extra boost radiators need by replacing the existing single or double panel radiators with the relatively new K3 radiators that have three panels and three sets of fins – providing the additional metal surfaces you need but without increasing the radiator footprint on the wall.
Major radiator manufacturers such as Stelrad have anticipated the significant move towards air source heat pumps in the UK and have added new, larger size radiators to their portfolio providing that option. They have also stepped up the options on the K3 radiator designs available too.
Larger surface areas
In addition, the huge popularity of vertical radiators has also offered a solution. Vertical radiators clearly have a smaller horizontal footprint than a traditional radiator, but they can be larger by design – taking up floor to ceiling space. It may be more practical and more attractive to have two modern vertical radiators in a room than one large standard radiator which traditionally has been placed along under the main window. Stelrad has developed a wider range of vertical radiators, adding a huge number of new designs and sizes helping to provide the larger radiators needed by the renewable heating options. These take up a much-reduced horizontal footprint to slot into smaller wall areas in a room, to provide the levels of heat required without taking up large wall areas that will cause confrontation with furniture in the rooms. Vertical radiators can be focal points in the room, part of the décor, and fit nooks and crannies in a room which traditional horizontal radiators won’t do as effectively.Sonewlow temperature heating systems offer additional opportunities for the products we know and love and have used virtually every day of our working lives, for years. There’s no need to change what we do, just an element of changing how we do it, and the questions we ask when undertaking an installation or specifying for a heating systemRadiatorsdesign.are very much ‘fit for the future’ but as always, correct sizing will need to be undertaken to ensure that they keep the home warm and cosy. But can radiators work well with air source heat pumps? Very definitely yes they can – and they already are in a host of installations across the UK.

The updated Building Regulations also mean that intermittent fans are now no longer suitable for very airtight dwellings. Unsurprisingly, Scotland, with its increased airtightness and ventilation requirements has already moved away from allowing trickle vents and intermittent fans and more towards whole house ventilation systems.
The updates to Approved Document L mean that new homes are now required to be increasingly airtight. Solving the problem by adding large numbers of windows with trickle vents may appear counterintuitive in a house which has been designed to be extremely airtight.
Approved Document F has many proposed changes that will affect how ventilation is specified for new homes.
One of the most fundamental is that whole house ventilation rates has been increased from 13l/s to 19l/s for a 1-bedroom property and up to 43l/s for a 5 bedroomed property. This increase will make it more challenging to meet ventilation rates, particularly in smaller properties, such as one-bedroom apartments, where, in the past, intermittent fans would have been used in ‘wet rooms’ rather than systems like MEV (Mechanical Extract Ventilation), for cost reasons.
Increased airtightness
June 2022 saw updates to two regulatory documents: Approved Document F - Means of ventilation (ADF) and Approved Document LConservation of fuel and power (L1A/L1B) (ADL) in England. These updates to Building Regulations pave the way towards the Future Homes Standard, which is due to be introduced in 2025. This brings with it a focus on thermal efficiency, increased air tightness and indoor air quality. The new regulations mean that a systems approach to ventilation is becoming the norm, which means specifiers and developers are working more closely with ventilation manufacturers to ensure homes are future proofed to meet and achieve the latest standards.

Main changes
So what does this mean for new homes?There are a number of options available to the new build sector. The most effective in meeting the new regulations is undoubtedly MVHR systems, which are becoming an increasingly popular choice. These whole house ventilation systems supply fresh air from outside into a property, as well as extracting air throughout the property.
The proposed new regulations also contain, for the first time, Approved Document O for mitigating overheating in England. Overheating is becoming more
MVHR also includes a heat cell which recovers between 70–95% of the heat from the exhaust air and greatly improves the energy efficiency of buildings.

Competent installation
Updates to building regulations mean that instead of a percentage of properties being inspected to meet requirements, every property will be inspected, therefore driving up industry standards.
Another major change that housebuilders and developers will notice in the updated Approved Document F is the removal of Systems 1 to 4. System 1 will change to Natural Ventilation, this involves intermittent fans in wet rooms such as kitchens, bathrooms and en-suites, the reference to System 2/Passive Stack has been removed; System 3 is now known as Continuous Mechanical Extract and System 4 is Mechanical Extract Ventilation with Heat Recovery.
A systems approach to ventilation is a much better option for new and refurbished homes and should make the whole process much simpler and straightforward for housebuilders.

For the first time, Approved Document F also includes upgrades to existing homes. When major refurbishment work is being carried out such as new windows or doors, insulation, loft conversions, then PAS2035 is the official document that complies.
Although an MVHR system like energiSava will switch to bypass and will drop the temperature slightly, in cases where overheating arises. Mechanical Extract Ventilation (MEV) systems are another popular option with housebuilders. These centralised systems help to reduce excess moisture by using multiple points in which to extract air. MEV systems provide year-round good indoor air quality, protecting a home from condensation, damp, and mould. The MEV unit is usually located in the loft or hallway cupboard in an apartment to provide ventilation to the whole property.
To make specification simpler, there is now only one document as the Compliance Guide has been integrated into Approved Document F. To simplify things further, the updated Approved Document F contains separate guidance for dwellings and nondwellings. Positive Input Ventilation systems are still an option providing they meet the F1(1) requirement in Approved Document F in England, Wales and Regulation 23 in Scotland: There shall be adequate means of ventilation provided for people in the building.

Now, more than ever, it is essential that an installer is a competent person and on NHBC sites this means having successfully passed an NICEIC Domestic Ventilation course. Installers then need to gain the experience to be able to be fully competent in installing ventilation systems.
Although ventilation is still not seen as one of the ‘primary’ services in a home, like electricity and heating, its importance is being heightened by the changes to Building Regulations. It is critical not only to specify the right type of ventilation system but also to ensure it is installed correctly to ensure the safe and comfortable running of the house.
When working with Approved Document F, Approved Document O gives guidance for removing excess heat from residential buildings. If this is to be corrected via windows or openings, the amount of ventilation required is likely to be in excess of the current purge ventilation rates under ADF. In some situations, particularly in urban areas or near airports, railways or motorways, it may not be practical to carry out natural ventilation through opening windows.

By working closely with the project’s designers, Vaillant’s aroTHERM plus heat pump was selected in conjunction with a Vaillant uniTOWER, an indoor unit, containing an integrated hot water cylinder and hydraulic components, to meet the domestic hot water and heating needs for each property on site.
Using the natural refrigerant R290, Vaillant’s aroTHERM plus has a global
One such project which has combined low carbon heating through the installation of air source heat pumps and off-site modular construction, is Civic Living at BasedHoulton.inRugby, the 38-plot development has been delivered by modular housing specialist, TopHat for Urban&Civic. It is situated on the larger 6,200 home Houlton development that will be developed over the next 15 or so years to include new schools, local centres, health provisions and supporting infrastructure for the growing town.
Modular approach As the project was modular, some of the construction of the homes was carried out at TopHat’s manufacturing site in Derby. This meant that at the design and planning stages, upmost precision was needed to ensure everything was manufactured to the exact specification needed and delivered to site to ensure construction schedules were met.
As the drive to provide low carbon housing intensifies, housebuilders are not only seeking sustainable products, but increasingly, focus is turning towards adopting new and more sustainable construction practices too.
Heating specialist, Vaillant, examines the role the company’s heat pumps played in a new development in Rugby, built using offsite modular construction.
TopHat needed a heating solution that would mirror the sustainable objectives of the project, providing future residents with a solution that would exceed the current environmental legislation and performance requirements, but would also be compliant with 2030 Net Zero targets.
When it came to the specification of the heating system, the company enlisted the support of Vaillant early on at the project’s concept stages, which meant the company’s team were able to provide the project’s developers with presales consultancy support. From the outset, Vaillant’s design services team were clear on the designs of the properties and could deliver a solution that not only complemented the aesthetics of the development, but also contributed to the overall goal of sustainable living. With this in mind, the company’s aroTHERM plus, an air-to-water heat pump, was specified to meet the heating and hot water demands for each of the 38 properties.
Adam Tilford, Sustainability Manager at TopHat said: “When it comes to selecting a partner to work with, first and foremost we’re looking for companies that have products that fit with our own. This is particularly important as a modular housing business, where tolerances are much tighter than with traditional construction methods, as it’s vital that components arrive on site ready to be built.
“For Civic Living project, Vaillant’s design services team was on hand to support the project’s developers from the onset. Using the individual housing designs of each housing type on site, Vaillant’s team was able to provide in-depth heat loss calculations which were used to provide fully indemnified heating designs. These were really important, as they gave added peace of mind to both us and also the project’s installation team.”
Adhering to British Standard EN12831, the heat loss calculations provided by Vaillant were then used to determine the size of the heat pump required for each property. And to further deliver optimal comfort for the future residents, the heat loss calculations were also used to ascertain the size of the radiators needed in each room.
warming potential of 3 and an ErP rating of A+++. The use of R290 also means residents can achieve greater comfort levels, as it enables the aroTHERM plus to run at a higher flow temperature of up to 75°C, which means that domestic hot water is stored at a useable temperature and legionella cycles can take place without the need for a backup heater.
On-site support Following the specification of the heating system, Vaillant’s team worked closely alongside the project’s installer, Sub Modular Ltd, to provide support throughout the project, which included in-depth product training for the installation team at Vaillant’s Centre of Excellence in Belper.
Ryan Mountney, Managing Director at Sub Modular Ltd, led the installation, he said: “The installation process for modular projects is slightly more complex than traditional construction methods. TopHat specified the use of an underground duct which is pre-insulated that meant some of our work needed to be carried out in tandem with the groundworkers to ensure our work was completed to schedule.”
Aesthetic appeal
Steve Cipriano, Commercial Director at Vaillant concluded: “Civic Living project is a forward-thinking development, so it was great to be able to work in close collaboration with TopHat on this from the project’s initial concept stages. This meant not only could we provide full support to the team from design through to installation and beyond, but in doing so we’ve been able to deliver each property on site a heating solution which meets 2030 Net Zero targets today.”

To further its support, Vaillant was also onsite to guide Sub Modular Ltd through the installation and commissioning of the first of the heating systems.
Adam Tilford added: “The focus for this project was to deliver residents a sustainable product and from the outset we knew we wanted to use the most efficient heating system to support this vision. The Vaillant aroTHERM plus provided the perfect solution. Not only is it playing a significant part in ensuring this project is meeting current building regulations, but the use of the aroTHERM plus heat pump, together with other sustainable technologies, has meant we’ve been able to reduce carbon emissions from the properties on site by more than 35-40% than current building regulations require us to.”
Ryan added: “Vaillant provided in house training to the team on the installation and commissioning of the aroTHERM plus and uniTOWER, which was really useful. We were able to take this knowledge and, together with some initial on-site support from Vaillant for the installation for the first units, install each of the heat pumps, before connecting them to the uniTOWER.”
Yet while TopHat’s primary focus for Civic Living project was to deliver sustainable living, it was also important that this didn’t come at the cost of aesthetic appeal for the residents. One of the main considerations to overcome here was the location of the heat pump itself, which needed to carefully balance the clearances required as part of the current building regulations, but also make sure the heat pump was located in a position that was aesthetically pleasing to the building around it. To overcome this challenge, TopHat specified the installation of a preinsulated underground duct which offered increased flexibility in the positioning of the aroTHERM plus. This meant each unit was able to be positioned in the rear of the property, minimising its impact on useable garden space wherever possible.
To complement the modular construction of the project, a Vaillant uniTOWER was installed within each property during the manufacturing process, with the final connection with the aroTHERM plus was made on site.

QWhat do the new regs require?
QHow can I be sure the system delivers maximum efficiency? Precision system design and installation are key for any heat pump and underfloor heating system. Simply put, if the system is not correctly designed, it won’t reach its desired efficiency and energy bills will be higher. Working with specialist suppliers which can provide up to date expertise and product knowledge is key. It’s also important that they take into consideration every aspect and parameter of the heating system, not just the product they areThisproviding.collaboration will enable each supplier to understand the requirements of each other’s technology to ensure the correct specification of all equipment, enabling seamless installation and operation of the finished system. Taking away the risk of any guesswork from either supplier’s calculations also ensures the system is able to reach maximum efficiency and reduces the risk of heat pumps being unnecessarily oversized, something which can affect both upfront capital and running costs.
With the combination of Heat Pumps and Underfloor Heating (UFH) maximumtheoutlinesaboutanswersunderfloorDirectorCrown,toincreasinglybecomingofinteresthousebuildersJoannaMarketingatWMSheating,somequestionsthepairingandhowtoensuresystemreachesefficiency.
The 2025 ban on gas boilers in newly build homes, along with recently enforced regulations, have opened up a new conversation around how we heat our homes today and in the future. In particular, the new low water temperature update to the Building Regulations and Part L has changed heating system specification choices to adhere to a maximum flow temperature of 55°C. All homes must also now feature a selfregulating control device which allows for zoning within the property.
With the drive towards zero carbon homes in mind it is expected that heat pumps will become the norm. However, these renewable heat sources achieve their most efficient COP (coefficient of performance) level when running between 35-45°C, so finding a partner technology which can achieve this is the key to creating an efficient heating system.
QWhy does underfloor heating work so efficiently with heat pumps? Hydronic (water based) underfloor heating, which runs at 45°C, is the ideal technology partner to maximise heat pump efficiency as the system can easily support the low flow temperatures required. As underfloor heating covers such a large surface area, the system doesn’t have to work as hard and therefore uses less energy, further reducing the system’s impact on the planet and energy bills. An air source heat pump (ASHP) combined with an underfloor heating system can result in every 1kWh of electricity required producing a further 4 kWh/COP of 4 (dependent on your chosen heat pump COP) of energy, which means it is 400% efficient.

Control is another key element to achieve system efficiency. It is also now a regulatory requirement for all new homes to incorporate a self-regulating control device which allows for zoning within the property. Heating a room that isn’t being used is a waste of energy, so the fact that underfloor heating can be fully zoned from each individual room

WEATHER PROTECTION
Morgan Construction Wales is a family-run business, building in excess of 200 high end homes across Wales each year. Malcolm Davies, Procurement Manager at Morgan Construction said: “We worked in partnership with Stephen Gore of Fassa from specification stage to completion to secure an integrated render and paint system to meet the project and Local Authority requirement. We were very satisfied with Fassa's 365 colour range which easily allowed us to choose a shade which would meet our client’s requirements.”
Liam Hassard –who founded the business along with Shane Hutchings in 2017, commented: “I used to have my own plumbing and heating company and we set up The BuildingDartmouthCompany to develop high quality, low energy properties. We purchased the barn complex about 18 months ago during the pandemic and set about turning them into stylish homes: trying to retain the character, but refurbishing them to have very good standards of insulation and modern technology. I undertook the MCS course back in 2012 and have been installing OMNIE systems throughout my career and have got to know the local OMNIE area manager, Rob Shute, very well and he helped us design and plan the M&E for the three barns. By getting the insulation up to modern standards and sizing the systems correctly we have had the underfloor heating in The Old Granary running at a 35-degree flow temperature and the living spaces were feeling really warm – before we even had the heat recovery systems operating.”

The conversion of three stone-built agricultural buildings near the Devon town of Totnes is employing a full selection of renewable and low-energy technologies from the range of Exeter-based manufacturer, OMNIE. The hundred year old buildings at Ritson Farm are being renovated by The Dartmouth Building Company, with the top end developer also leading the conversion work.
Fassa Bortolo’s specialist team has worked with the developer on the luxury estate to provide a suitable facade ensuring the best level of protection for the properties. Covering a total surface space of over 10,000m2, KC1 was used as a base coat, followed by a priming undercoat of FX526 and a layer of PX505 acrylic-siloxane paint in shade Pastel White, SA22 and TS03 to finish.

PROVIDED BY FASSA BORTOLO Italian render manufacturer Fassa Bortolo is working with building developer, Morgan Construction Wales and has recently completed work on one of the Welsh housebuilder’s prestigious developments: the Cornfields Estate in Sageston, Pembrokeshire. The site is located in an area classified as having ‘very severe’ weather by the rain driven index. As a result, it was essential that Fassa specified a complete integrated render and paint system to effectively weather-proof the 60 new dwellings, which consist of two bed bungalows and two, three and four bed houses.
The average air test result for the 12 homes came in at below 0.5 ACH. A Larsen truss panel (a lightweight wall extension which creates extra wall space to house insulation) was also used in the project. It was 330mm deep with the finished wall make-up being closer to 500mm. Darren Jarman, Managing Director of Lowfield Timber Frames, commented: “The Highfields scheme in Cardiff was just one of several passivhaus schemes we have completed over the past 2 years. We now have an external wall build-up that not only meets the passivhaus standards, but also has extremely low embodied carbon“Thecredentials.externalwall has been fire tested and achieves the airtightness required, all in all, reducing the heating requirements and the running costs of the property.”
“This is down to StormBrixx’s stackable design, meaning more units can be packed and delivered on a lorry. Not only this, but the unit is light and easy to handle by hand, so once delivered to site, there was no need to then use heavy machinery to lift or transport the products into position. This then meant that installation was much quicker too.”

ACO Water Management has designed and delivered a 4,500m³ StormBrixx attenuation tank to help prevent flooding at Lovell Homes’ Drummond Park estate. A mixed tenure development comprising of 412 quality homes, work at Drummond Park commenced in May 2022. Consisting of 309 two, three, and fourbedroom homes for sale and 103 affordable homes for rent, the site required a large-scale solution to mitigate flooding from storm and surface water runoff. ACO’s StormBrixx attenuation system was specified and installed with a depth to invert of 4.5m, following a consultation between civils contractor Tithegrove and ACO. Measuring 56.4m long by 26.6m wide by 2.4m high, the tank consists of 13,254 StormBrixx SD units which are stacked together in three layers. With a total volume of 4,500m³, it allows stormwater to slowly infiltrate back into the ground and soak away.

Colour blocks
Another popular trend is colour block painting and with this, you can create real character. For instance, in a kitchen/dining/family room you could paint a central strip to draw the eye to a focal point, such as dining table, or make a striking backdrop for a further feature such as a wall mounted media unit. In bedrooms you can create attractive arches and curves, or even a canopy by partially painting three walls and the ceiling. We strongly advise not to forget the ceiling. Painting this can really add depth to a room, or make a child’s bedroom more imaginative; recently we’ve added murals depicting the night sky, planets, and even a football pitch. Both wallpaper and block painting easily compliment other treatments such as mirror walls, picture rails and panelling. Don’t be afraid to deliberately contrast, or add more than one feature wall, perhaps one panelled and one painted. For extra creativity, why not trying layering your wall treatments? So you might consider two different coloured paint blocks with panelling over the top, or a half height wallpaper alongside painting above/below. Other decorative wall installations we’ve embraced are full height headboards with wallpaper or a moody mirror wall either side; photo galleries with colour block painting behind to give an illusion of a frame – this works well in hallways, stairwells and landings. Macramé, canvases, and oversized wall-hangings such as Moroccan or Indian tapestry are also great for showcasing your personality and adding texture and tacticity.
W hen thinking of changing a room’s interior design, walls can often be an afterthought. It’s easy to get preoccupied with furniture and fabric choices but our advice is wait, and consider your wallcoverings first. These offer extreme versatility, from changing colour or creating an eyecatching feature to embracing a theme or adding texture and depth, there are plenty of wall treatments that can instantly transform the look and feel of a space. Firstly, the obvious choice, wallpaper. This will never go out of fashion and is something we’re asked about so frequently that we created a dedicated social media series, Wallpaper Wednesday, to highlight some of our favourite styles and how to use them including full coverage, half height, or as a feature. In living rooms and home offices, we favour a statement wall and there are some superb patterns to achieve this, whether that’s botanical, geometric, art deco, textured or even with iconic landmarks and characters. On our recent installs we’ve used a Palace of Versailles print and one with the Mary Poppins umbrella. If you’re not feeling especially brave, downstairs cloakrooms and utility rooms are ideal for experimenting with bolder wallpaper designs. They can add drama to smaller spaces but are also simpler to redecorate if you change your mind.
