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

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.

Conclusion
EnerPHit represents the pinnacle of energy-efficient retrofitting, aiming to bring existing properties to levels of energy efficiency comparable to Passivhaus standards. While retrofitting poses unique challenges compared to new builds, the EnerPHit standard provides guidelines and benchmarks for achieving exceptional performance. With careful planning, skilled design teams, and a comprehensive understanding of the complexities involved, EnerPHit retrofit projects can transform existing properties into low energy and low embodied carbon homes.
By adhering to the principles of EnerPHit and working towards certification, you ensure rigorous quality assurance, airtightness performance, and adherence to the design objectives. While EnerPHit retrofit costs can vary depending on the complexity of the project and project location, the long-term benefits of improved energy efficiency, comfort, and reduced carbon emissions make it a worthwhile investment for homeowners looking to create sustainable living spaces.
So, if you’re considering renovating your home with the goal of achieving high levels of comfort and thermal performance, now is the time to plan for an EnerPHit retrofit. Embrace the challenge, work with knowledgeable professionals, and unlock the potential of your existing property to become an energy-efficient haven that aligns with your sustainability goals.

After two decades of experience as an architect in a small contemporary design-led architecture studio, my work has always been rooted in the principles of low energy and low embodied carbon designs. But beyond the energy efficiency of the designs, there’s another key aspect of renovations and home extensions that often goes overlooked: the intricacies of party wall agreements. This article delves into this crucial component of home renovation from an architect’s perspective.

1. The Party Wall: What It Means for Homeowners
At the heart of many terraced, semi-detached, and apartment homes lies the party wall. This wall, shared between neighbours, represents not just a physical boundary but also shared ownership. Its significance becomes even more pronounced when structural renovation works, that impact the party wall, are being considered.
2. Recognising the Role of the Party Wall Surveyor
In our line of work, we often encounter clients who are unfamiliar with the concept of a party wall surveyor. Acting as an impartial consultant, their primary role is to serve the interests of both the person renovating and their adjoining neighbours. It’s paramount to introduce the significance of a party wall surveyor early on in our project discussions.
3. Decoding the Party Wall etc. Act 1996
The legislation guiding party wall agreements is the Party Wall etc. Act 1996. It’s crucial to understand this piece of legislation, as it dictates when homeowners are legally required to involve their neighbours in building works. Whether it’s an extension that utilises the party wall as a support or excavation works within close proximity of the party wall, the Act covers a broad range of scenarios.
4. Engaging a Party Wall Surveyor: The Essential Steps
It’s tempting to think that homeowners can navigate the process of party wall notices themselves, but the wisdom of experience suggests otherwise. Richard Egan from Osprey Building Consulting, an expert we’ve collaborated with on many projects, emphasises the importance of professional involvement. A party wall agreement, if not done right, can lead to complications and disputes later down the line.
5. Timing is Everything: The Importance of Notice Periods
Understanding the notice periods is pivotal to a smooth renovation process. The Act specifies various periods depending on the type of work being done. It’s our job as architects to guide clients through these timelines, ensuring no premature steps are taken.
6. A Singular Wall, Multiple Surveyors
When served with a party wall agreement, neighbours have a choice: they can either accept the proposed works, dissent and opt for your chosen surveyor, or dissent and select their own party wall surveyor. This often means more than one surveyor might be involved, particularly in scenarios involving multiple neighbours sharing the same party wall. Please see the table below for more permutations of what could happen with regards to the Party Wall process.

Remember, the table is just a basic representation and covers only three potential work types as examples. The Party Wall etc. Act 1996 has many more stipulations, and depending on your need, you might want to expand upon this table or add further details to cover the full breadth of the Act.
7. Condition Surveys: Protecting All Parties Involved
Before the commencement of any work, party wall surveyors carry out condition surveys. These visual assessments of the existing state of neighbouring properties ensure that all parties have a clear understanding of the property’s current condition, which can be vital in addressing potential disputes down the road.
8. Dispute Resolution: Making Room for Agreement
One of the primary roles of a party wall surveyor is to aid in dispute resolution. When a party wall award is provided by the surveyors, any existing disagreements between neighbours are typically addressed. However, homeowners do have the right to appeal a party wall agreement if they find it unsatisfactory.
9. Costs Involved in a Party Wall Agreement
Party wall surveyors generally charge based on the time they invest. Osprey Building Consulting Ltd, for instance, proposes a fee ranging from £850 to £1300, accounting for an average 7-9 hour commitment for standard projects. However, the rates can differ significantly depending on the firm selected and its geographical location. We maintain a list of party wall surveyors to recommend to our clients and offer guidance on their fees at the beginning of your venture. Of course, you’re always welcome to seek recommendations from acquaintances or relatives.
The process can become notably intricate and expensive when a project is adjacent to several flats sharing the same party wall. In such instances, agreements might be required with each flat. To assist in budgeting for such scenarios, we incorporate these potential costs in our preliminary fee outline for renovators. Additionally, we always advocate for a contingency buffer, suggesting an allocation of 10-15% of your total budget to cover unexpected expenses.
10. An Architect’s Final Word on Party Wall Agreements
In our years of expertise, we’ve understood the critical role that proper planning and legal adherence play in home renovations. A party wall agreement might seem like just another step in the process, but its significance is unparalleled. A well-structured agreement ensures peace of mind for all parties involved, laying the groundwork for a successful renovation project.
Our goal as a contemporary design-led architecture studio is not just to create designs that are aesthetically appealing and energy-efficient, but also to ensure that the journey towards realising these designs is smooth and legally sound.

Through the years, our firm has dived deep (literally!) into many basement projects, harnessing the potential beneath our feet. Here’s what you need to know.
1. The Allure of the Underground: Why Basements?
Many of London’s conservation areas and sensitive locations pose restrictions on above-ground extensions. This leaves homeowners with a basement as the prime alternative for extra space. It’s not a mere excavation but an investment, both financially and emotionally.

2. How Much Will a Basement Cost?
Starting at around £5,200 per square metre (plus VAT), the initial figures might be intimidating. But, consider this: basement extensions have been known to add a value ranging from £8,500 to an astonishing £23,000 per square metre, especially in upscale areas like West London. For those purely concerned with the financial aspect, this is a promising ROI.
3. The Factors At Play: Why Are Basements Expensive?
Unlike traditional extensions, basements demand more. From excavation to waterproofing, structural interventions to advanced plumbing, the challenges are manifold. Then, there’s the question of lighting. Strategically placed light scoops or double height spaces can work wonders, but they come at a cost.
4. External Components: Going Beyond the Underground
It isn’t just the basement’s interior that demands attention. Externally, one needs to think about light wells, landscaping, rooflights, and more. Furthermore, ventilation becomes crucial, and mechanical solutions might be required to maintain the air quality.
5. Safety First: The Access and Exit Dilemma
In any architectural project, especially basements, safety remains paramount. Apart from the main access, a secondary escape route is essential, ensuring an alternative exit during emergencies.
6. Versatility of Basements: Endless Possibilities
Basements aren’t just storage dungeons. Imagine a serene yoga room or a private cinema lounge. Yes, these can be demanding in terms of cost, but the luxury they offer is unparalleled.
7. Consulting the Experts: Whom to Seek?
Planning a basement isn’t a solo endeavour. Architects, structural engineers, cost consultants, and even party wall surveyors play pivotal roles. As a rule of thumb, consultant fees might oscillate between 11% to 19% of the construction cost, with additional charges for building regulations and party wall agreements.
8. Delving Deeper: The Pre-Planning Phase
Basements are intricate. From geological surveys to assessments of the ground to sun and daylight reports, multiple assessments are crucial. Don’t be startled by the initial investment, as these reports pave the way for a seamless construction journey later.
9. Crafting the Perfect Basement: Aesthetic and Functional Considerations
While the functionality of a basement is important, so is its aesthetic appeal. Using warm, natural materials can transform the space, making it cosy and inviting. Leveraging the basement’s inherent qualities, such as low light, can even be an advantage.
10. The Final Verdict: Is a Basement Worth It?
Constructing a basement is undeniably costlier than above-ground extensions. But, if site restrictions hamper above-ground development, a basement becomes a beacon of hope. It offers the luxury of additional living space without the hassle and expense of relocating.
