As an architect with two decades of experience, I have witnessed the evolution of sustainable design principles and their integration into contemporary architecture. In recent years, the focus has shifted towards low energy consumption and low embodied carbon designs. One crucial element in achieving these goals is Mechanical Ventilation with Heat Recovery (MVHR). In this article, I will delve into the concept of MVHR and explore its significance in creating environmentally conscious buildings. Join me on this journey as we unlock the secrets of MVHR and discover how it can revolutionise the way we think about ventilation.
MVHR, also known as Heat Recovery Ventilation (HRV) or Comfort Ventilation, is a system that provides fresh, filtered air into a building while retaining most of the energy that has already been used for heating. Its primary purpose is to meet the ventilation needs of energy-efficient buildings. Imagine a mechanism that not only supplies filtered clean air but also ensures optimal energy efficiency by recovering heat that would otherwise be lost. That is precisely what MVHR offers.

One Simple Principle
At its core, MVHR operates on a simple principle: it extracts air from polluted sources such as kitchens, bathrooms, toilets, and utility rooms, while simultaneously supplying fresh air to the living spaces, such as bedrooms, living rooms, and studies. The extracted air is then passed through a central heat exchanger, where the heat is recovered and transferred to the supply air. This process works both ways: if the air inside the building is colder than the outside air, the coolth is maintained within the structure. The result is a constant supply of fresh, filtered air that ensures high air quality, all while remaining practically imperceptible to the occupants.
Airtightness
Now, you might be wondering about the ideal level of airtightness required for MVHR to be worthwhile. While MVHR can be installed in any building, there is a rule of thumb that justifies its use only when the air permeability of the thermal envelope is at or below 3 air changes per hour, as tested at 50 Pascal. This value is roughly equivalent to 3 m³/m².h @ 50 Pa for average dwellings. Recent research conducted by the Passivhaus Trust suggests that MVHR ventilation could still be employed in less airtight homes, even those with a draughtier air permeability rate of 9 m³/hr/m² @ 50 Pa, as it would still yield lower carbon emissions compared to natural ventilation. However, it’s important to note that in very draughty homes, where the air permeability rate is worse than 9 m³/hr/m² @ 50 Pa, the efficacy and efficiency of an MVHR system may decrease.

Temperature Difference
You might wonder why the temperature difference between the interior and exterior of a building is crucial for MVHR to function optimally. The answer lies in the phenomenon of thermal stacking, also known as the chimney effect. When there is a significant temperature difference, the natural buoyancy of warm air causes it to rise, creating a pressure difference that facilitates ventilation through the leakiness of the building envelope. In windy conditions, the wind acts as the driving force for ventilation. By implementing intermittent extraction points, such as in the shower or kitchen, a portion of the leakiness is reversed, enhancing the effectiveness of MVHR.
Addressing Condensation
Addressing condensation is another important aspect to consider when contemplating the installation of MVHR. If a building has poor insulation, thermal bridging, or other sources of damp ingress due to inadequate damp proofing, it might be tempting to seek technological solutions. However, I would strongly advise addressing the root cause of the problem rather than treating the symptoms. While MVHR can help reduce the symptoms of condensation and prevent mildew formation, resolving the underlying issues will yield more sustainable and long-lasting results.

The importance of a well designed MVHR system
The importance of good MVHR design cannot be overstated. Whether you are incorporating MVHR into a new build or a refurbishment project, it should be considered from the early planning stages. The devil is truly in the detail when it comes to MVHR system design. The efficiency and effectiveness of the system rely on meticulous planning, ensuring that ducts are run strategically throughout the building. The layout of rooms can even be influenced by ventilation requirements, demonstrating the integral role MVHR plays in the overall design.
Moreover, the installation of MVHR has implications for heating system design. One notable effect of heat recovery ventilation is the equalisation of temperatures throughout the building. This means that it becomes important to prioritise the heat supply to specific rooms that should be warmer than others. In high-quality buildings, it may even be sufficient to directly supply heat to these select areas, further optimising energy usage.
Frequently Asked Questions
Q: What is MVHR?
A: MVHR stands for Mechanical Ventilation with Heat Recovery. It is a system that provides fresh, filtered air to a building while recovering the heat from the outgoing air, thereby improving energy efficiency.
Q: How does MVHR work?
A: MVHR works by extracting air from polluted areas such as kitchens and bathrooms and supplying fresh air to living spaces. The extracted air passes through a heat exchanger, where the heat is recovered and transferred to the incoming air.
Q: What is the ideal airtightness level for MVHR?
A: While MVHR can be installed in any building, its use is typically justified when the air permeability of the thermal envelope is at or below 3 air changes per hour, as tested at 50 Pascal. This ensures optimal performance.
Q: Can MVHR be used in less airtight homes?
A: Recent research suggests that MVHR can still be employed in homes with less airtightness, but the efficacy and efficiency of the system may decrease in very draughty homes.
Q: Does MVHR help with condensation issues?
A: MVHR can help reduce condensation and prevent mildew formation, but it is crucial to address the underlying causes of poor insulation and damp ingress for a more sustainable solution.

EnerPHit aims to achieve similar levels of energy efficiency as Passivhaus for retrofitted buildings. In this guide, I will provide you with a comprehensive overview of EnerPHit, its requirements, the benefits it offers, and the considerations you need to keep in mind if you are planning a retrofit project.
EnerPHit vs. Passivhaus
While Passivhaus standards are primarily applied to new builds, EnerPHit focuses on retrofitting existing properties. Retrofit refers to a form of renovation aimed at significantly reducing energy consumption and improving the thermal performance and comfort of a home. Unlike Passivhaus, which can start from a blank canvas, retrofitting involves working with existing buildings where many elements like geometry, orientation, and structural approach are already predetermined. Additionally, retrofit projects may have thermal bridges (or cold bridges) that are challenging to eliminate completely.
The EnerPHit standard acknowledges these challenges and sets slightly lower performance requirements compared to Passivhaus, considering the limitations of retrofitting existing buildings. To meet the EnerPHit standards, a space heating and cooling demand of 25 kWh/m2/year is required (compared to the Passivhaus standard of 15 kWh/m2/year). Airtightness performance should achieve 1.0 air changes per hour (compared to the Building Regulations for new homes, which require between 5 and 15 air changes per hour). While achieving these standards may use more energy than Passivhaus, it still represents a significant improvement over most existing homes and even new builds.

Guidelines and Design Considerations
EnerPHit provides a benchmark for renovators to work towards. Similar to Passivhaus, the Passivhaus Planning Package (PHPP) design tool is used when designing an EnerPHit scheme. This tool helps deliver more efficient buildings by considering factors like orientation and geometry at an early design stage. The PHPP enables informed decision-making regarding retrofit measures, cost implications, and energy considerations.
It’s important to note that retrofitting is not an easy task, and achieving the EnerPHit standard requires careful planning and execution. The thermal and airtightness strategies are likely to be more complex and challenging on site compared to new builds. Balancing the pros and cons of internal or external insulation is a critical consideration, as well as addressing potential moisture issues that may arise from changing the building fabric. Undertaking an EnerPHit retrofit demands a skilled and knowledgeable design team that can navigate these complexities.
Retrofit Measures and Certification Process
When carrying out an EnerPHit retrofit, several measures are required to meet the standard. These include:
High levels of insulation, either internal or external (with internal insulation requiring more attention to moisture risk)
High-performance triple-glazed windows and external doors
Careful window installation
Achieving an airtightness reading of 1.0, and
Implementing a Mechanical Ventilation with Heat Recovery (MVHR) system.
To receive EnerPHit certification, the process is similar to working towards Passivhaus certification. The project must be designed using the PHPP and certified by an accredited Passivhaus certifier. While the products used in the retrofit do not need to be Passivhaus certified, having certified products, especially for MVHR equipment, can be beneficial.
To make EnerPHit retrofits more accessible, the Passivhaus Institute has introduced the EnerPHit Retrofit Plan, a step-by-step certification process that allows payments for certification to be made in stages. This helps with funding for retrofit projects and provides a structured approach to achieving certification.

Cost Considerations
The cost of an EnerPHit retrofit can vary depending on the complexity of the existing building. As a general guideline, budgeting around £800-£1,000 per square meter for deep retrofit/EnerPHit, excluding VAT, is advisable. When considering specific components or systems, expect to pay around £10,000 for an MVHR unit installed in an average-sized house and approximately £400-£600 per square meter for windows and doors. However, the major costs lie in labor, as the installation of insulation and airtightness measures is time-consuming and requires meticulous attention to detail.
Insulation and Retrofit Challenges
One of the significant challenges faced by retrofitters is determining the optimal placement of insulation to improve the energy efficiency of existing houses. Regardless of where the insulation is placed, it is likely to create some issues. Internal wall insulation, for example, raises concerns about condensation and mold growth. When insulation is added to the inside of a wall, it can make the wall colder and disrupt the balance that previously allowed moisture to evaporate. This can lead to trapped moisture within the new wall assembly.
The Society for the Protection of Ancient Buildings (SPAB) has highlighted the issue of interstitial condensation and conducted research to better understand when and where it may occur. While specific recommendations may vary, the general advice is to avoid internal wall insulation in very exposed locations with porous external surfaces, as it can interfere with moisture management. This advice applies to buildings of any era, not just ancient ones.

Is EnerPHit Right for Your Home?
Considering an EnerPHit retrofit makes the most sense when you are already planning renovation or remodeling work on your house. If you are contemplating changes to your home to improve energy efficiency, EnerPHit offers a compelling opportunity. For instance, when replacing the roof or windows, it becomes easier to justify investing in high-performance materials that align with the EnerPHit standards.
While an extension project may not be the ideal time for a retrofit, it provides an excellent opportunity to create a long-term whole house plan that integrates the extension seamlessly and ensures compatibility with future retrofitting efforts. Planning for an EnerPHit retrofit from the beginning can help you achieve high levels of comfort and thermal performance in your home.

In conclusion, Structural Insulated Panels (SIPs) dispel the misconception surrounding their load-bearing capabilities. They can function as both a complete structural system and as infill walling for various frame structures, offering architects a wide range of design options. By harnessing the thermal efficiency and structural strength of SIPs, architects can create buildings that are not only environmentally sustainable but also architecturally remarkable.
Chapter 5: Analysing the Cost Implications of Structural Insulated Panels
5.1 Initial Investment vs. Long-Term Savings
It is essential to evaluate the cost implications of SIPs, considering both the initial investment and the long-term savings. While SIPs can be more expensive upfront compared to traditional timber frame constructions, the overall project costs typically increase by only 3-5%. The time saved during construction, reduced energy consumption, and enhanced thermal performance can offset the initial investment over the lifespan of the building.
5.2 Cost Comparison with Other Wall Systems
When comparing the costs of different wall systems, brick and block constructions may appear to be a more cost-effective option per square meter. However, the extended construction timeline, additional expenses associated with insulation, and challenges in achieving similar levels of airtightness make SIPs a competitive choice. By carefully managing construction details and employing skilled contractors, the overall additional cost of SIPs may be more minimal than it initially appears.
Chapter 6: SIPs Panel Types
When it comes to Structural Insulated Panels (SIPs), architects face a choice between two primary panel types, each offering unique advantages. Below, we explore these options to help you make an informed decision for your low-energy design project.
1. Sandwiched Panels (OSB-Polystyrene):
Thermal Efficiency: These panels excel at insulating, helping maintain stable indoor temperatures and reducing energy consumption.
Structural Strength: They provide robust construction, with resistance to wind and seismic forces.
Ease of Construction: Standard sizes and straightforward installation streamline the building process.
2. Urethane-Infused Panels:
Enhanced Insulation: Urethane foam offers superior thermal efficiency, ideal for stringent energy conservation standards.
Reduced Thickness: Thin profile, equivalent insulation values – suitable for space constraints or modern aesthetics.
Moisture Resistance: Resistant to moisture, making them great for humid or damp climates.
Collaborate with Experts:
Consult reputable SIPs manufacturers to align panel choice with your project’s specific needs. Their expertise ensures your selection suits your goals perfectly.
Chapter 7: Unveiling the Joining Techniques for Structural Insulated Panels
Creating an effective jointing system is crucial to achieving optimal thermal performance and airtightness with SIPs. Architects must explore different jointing techniques, such as using c24 timber for structural joints or employing spline joints for non-structural elements. Additionally, manufacturers offer unique jointing systems utilising mini panels to enhance wall U values and minimise air leakage at connection joints. By choosing the appropriate jointing techniques, architects can ensure the long-term performance and durability of the SIPs building.

RISE Design Studio, a small contemporary design-led architecture studio with 20 years of experience, is passionate about creating low-energy and low-embodied carbon designs. We believe in the power of sustainable architecture to combat climate change and create a better future for generations to come. That’s why we stand with MPs who are calling on the UK government to reduce VAT on green home improvements.
In an encouraging move, the UK government has announced its plan to scrap VAT on green home improvements for the next five years. Chancellor Rishi Sunak has expressed his intention to cut VAT to zero on solar panels, heat pumps, and insulation installed in British homes. While the details are yet to be clarified, including whether the VAT reduction covers installation or just materials and products, this initiative holds great potential. By making green home improvements more affordable, the reduced VAT will enable more people to enhance the energy efficiency of their homes.

The significance of this decision lies in the UK government’s legally binding commitment to reduce the country’s carbon emissions by 78% by 2035, compared to 1990 levels. This ambitious carbon reduction plan, the most progressive in the world, is a commendable step toward achieving Net Zero emissions by 2050. However, for this commitment to translate into tangible action, the government must implement measures that support and encourage green home improvements. Industry experts strongly urge the government to fulfil its promise by reducing VAT on such initiatives.
One crucial area that requires urgent attention is the high reliance on fossil fuels for heating UK homes. Astonishingly, over 90% of UK homes are heated using gas and oil, accounting for nearly 20% of the country’s carbon emissions. Surveys have shown that almost 80% of UK residents support renewable energy for electricity and heat. However, the adoption of renewable energy solutions has been slow, with only 36,000 heat pumps installed in the UK in 2020.

To meet the government’s ambitious target of achieving Net Zero by 2050, the Climate Change Committee (CCC), an independent government advisory group, recommends a significant increase in the number of heat pumps. The CCC suggests that by 2025, the UK should have 415,000 heat pumps installed annually. Although the government has committed to reaching 600,000 installations per year by 2028, this falls short of the CCC Pathway, which calls for 900,000 installations by 2028 and 1.1 million by 2030.
The high initial cost of energy-efficient home improvements remains a major barrier preventing many individuals from investing in these sustainable upgrades. By maintaining VAT at 20% on green home improvements, the government exacerbates this obstacle. It is crucial for the government to do more to reduce this financial barrier and ensure that greener heating options are accessible to all.
The Department for Business, Energy, and Industrial Strategy is preparing a new policy aimed at reducing carbon emissions from home heating in the UK, with an expected release later this week. However, according to The Guardian, ministers seem resistant to pressure from MPs, environmental experts, and the construction industry to reduce VAT on green home improvements.
It is worth noting that VAT on energy-saving improvements to existing homes increased from 5% to 20% in October 2019. At the time, HMRC cited EU tax laws as the reason for this increase. Now that the UK has left the EU, we are no longer bound by these tax laws. It is high time for the government to amend this policy and fulfill its promise to exercise control over taxes as a consequence of leaving the EU.
Interestingly, while new builds are not subject to VAT, green home improvements for existing homes are still taxed at the higher rate of 20%. This discrepancy seems illogical, as minimising the carbon footprint of existing homes is often the more sustainable option.
Regrettably, the government’s commitment to addressing the climate emergency has been marred by the withdrawal of support. In a puzzling move, the government terminated the Green Homes Grant initiative after just six months, offering little explanation. Under this scheme, homeowners could receive grants of up to £5,000 or £10,000 for energy-efficient home improvements. Consequently, the absence of this scheme leaves little government support or incentive for individuals seeking to reduce the carbon emissions of their homes. Additionally, the tax rate on burning fossil fuels for home heating remains at a mere 5%.
This lack of government support and the higher tax rate on green home improvements adds to the challenges faced by those considering transitioning from gas boilers to greener heating options like air source heat pumps. It is essential for the government to align its actions with its commitment to reducing the UK’s carbon emissions and ensuring affordable and accessible energy for all. By lowering the VAT on green home improvements, the government would demonstrate its genuine dedication to assisting individuals in making these crucial changes.

Furthermore, the government must prioritise helping people living in social and rented housing to lower their energy bills and reduce their carbon footprint. The government should ensure that policies enabling home improvements are not exclusive to homeowners but also extend to those living in social housing. The current provision of reduced VAT on energy-saving home improvements for specific benefits recipients falls short of addressing the needs of those on lower wages. Even for those who qualify for reduced VAT, affordability remains an obstacle for the majority.
NGOs such as Insulate Britain are calling on the government to implement policies that guarantee adequate insulation for all UK homes by 2030. They urge the government to prioritise insulation in social housing (including both council and housing authority-owned properties) by 2025. Without a comprehensive insulation policy, the risk of widening the poverty divide looms large, as individuals living in energy-inefficient homes face higher heating and electricity bills.
It is also worth noting that there is currently no direct incentive for private landlords to improve the carbon and energy efficiency of their properties. While tenants would benefit from lower energy bills and improved comfort, the increase in rental yield remains minimal. However, as awareness of the advantages of living in energy-efficient homes grows, this may change.
One effective approach to ensure action is for the government to enforce legal requirements regarding insulation and energy efficiency levels in homes. By doing so, the government would compel landlords to take steps toward creating a greener society. This approach would guarantee that no one is left behind on the path to sustainability.

Refining Sustainability in Renovation
We all recognise the importance of sustainable living. In our daily lives, we’re consuming less, and recycling more and, in our homes, many of us are improving rather than moving. However, renovation too has a significant environmental impact. It is crucial that we find ways to mitigate this, reducing our construction emissions through sustainable design and construction practices. Our studio has made considerable strides in this area, controlling our construction material choices, recycling existing materials, employing prefabricated elements and reducing waste.

The attention and interest generated by this 99m2 cinema 🎥 extension has been truly humbling!
RISE Design Studio has completed the refurbishment and extension of London’s only social enterprise cinema, The Lexi, in Kensal Rise.
A treasured asset within the local community, RISE revitalised a 99 sqm parcel of vacant land in the rear car park of the existing Edwardian gabled brick theatre. RISE and The Lexi consulted Brent Council who advised the initial concept, a formal beer garden, would not be possible due to noise constraints but an enclosed second screen might be feasible. RISE conceptualised an environmentally-driven second cinema and bar to accommodate the growing community programme and help drive revenue for The Lexi’s ecological charity efforts. Brent were instrumental in supporting the project – titled The Lexi Hub – through continuous advisory, ensuring planning policy and community needs were balanced.
Following a successful two year fundraising campaign including grants from the Brent NCIL, a contribution of £50,000 from the Mayor of London’s community fund, and local donations, The Lexi and RISE submitted a planning application backed by 1,211 local signatories, construction began in July 2020.
Located in a residential area, The Lexi Hub required a sensitive design approach to exercise consideration to the close neighbouring adjacent homes. An exercise in community partnership, RISE conceptualised an extension that reciprocates the same care and thought for the community which is wholeheartedly shown to The Lexi by local patrons. The architects designed a sunken extension, digging down 1.5m to reduce the new Lexi Hub’s massing, ensuring the extension sits only 2m above the neighbouring garden wall while also enabling level access from the car park. The Lexi Hub seats up to 30 viewers, with flexible accessible space for two wheelchairs or panel discussions and events, and features a new bar.
RISE reduced visual bulk further by echoing the neighbouring parapet roofs, creating a solid superstructure of in situ cast concrete arches which lean away from neighbouring gardens on a 45º angle. Reclaimed London stock brick was used to anchor the extension in its setting and buffed stainless steel to reflect the sky above, conceived as a natural cinema screen which camouflages the roof form. A green wildfower roof replaces biodiversity lost at a higher level. Choosing sustainably-minded options where possible, The Lexi Hub is sealed for airtightness to minimise heat-loss and energy usage, and also features a MVHR system. The Lexi is one of the first cinemas in the UK to regulate temperature and air quality through MVHR opposed to AC.
During construction of The Lexi Hub, a fire caused major smoke damage to the original cinema, Screen One, requiring a complete refit of the existing interiors. RISE salvaged original period details and character including the parquet flooring, which was restored and reinstated to the Box Office. The accident was seen as an opportunity to create a new cohesive interior language throughout the cinema’s facilities and spaces. Raw blush plaster and black walkways act as wayfinding devices, directing patrons from the Box Office down a glazed side extension to a newly refurbished bar, onto ScreenTwo.
A full list of the shortlisted projects is available on the Architects’ Journal website. Winners are announced at the awards evening on Friday 12th May 2023.
A review of the project by Fran Williams with photographs by Henry Woide was featured last August in the Architects’ Journal, please see here for the article.
