Passivhaus Design

At Metters and Wellby, we are excited to bring our Passivhaus design service to Cornwall. In today’s world, energy performance and sustainable building practices are more crucial than ever.

What is Passivhaus?

Passivhaus, or “passive house,” is a German concept revolutionising sustainable building design. It emphasises:

Energy Efficiency

Passivhaus structures reduce energy consumption for heating and cooling by up to 90% compared to conventional buildings.

Comfort

These buildings maintain consistent indoor temperatures and superior air quality.

Environmental Consciousness

Passivhaus contributes to a healthier planet by minimising the carbon footprint.

Benefits of Passivhaus

Substantial Cost Savings

Reduced energy consumption translates to lower utility bills for occupants.

Healthier Indoor Environment

Advanced ventilation systems ensure superior air quality.

Consistent Temperatures

Enhanced insulation and airtight construction prevent drafts and cold spots.

Environmental Impact

Significantly lowers the carbon footprint, contributing to a sustainable future.

How to Achieve the Passivhaus Standard in the UK

At Metters and Wellby, we’re here to help you achieve the Passivhaus standard in a beautifully designed home. Creating an energy-efficient home starts with understanding what matters to you—how you want to live, the spaces you enjoy and the budget you have available. At Metters & Wellby, we take time to get to know you and your project. Our small, collaborative team brings together design, planning, technical and interior expertise, alongside in-house skills in Passivhaus design and energy modelling. Whether you are interested in pursuing Passivhaus certification or simply want a comfortable home that needs less energy, we can help you explore the options and bring these considerations into the design from the outset.

Accurate Design Modelling

Utilise the Passive House Planning Package (PHPP) for precise design and performance predictions.

High Levels of Insulation

Employ meticulous insulation techniques to minimise heat loss.

High-Performance Windows

Install windows with insulated frames to enhance thermal efficiency.

Airtight Building Fabric

Ensure the building envelope is airtight to prevent unwanted air leakage.

Thermal Bridge-Free Construction

Design and construct to eliminate thermal bridges, reducing heat transfer through the building envelope.

Efficient Ventilation System

Implement a mechanical ventilation system with highly efficient heat recovery to maintain air quality and reduce energy use.

Conclusion

Embracing Passivhaus principles is more than just constructing buildings; it’s about fostering a sustainable future. By significantly reducing energy consumption and promoting environmental consciousness, Passivhaus designs pave the way for greener living.

Get in Touch

Interested in a Passivhaus design? Contact us to discuss how we can help create a sustainable and energy-efficient building tailored to your needs.

Samuel has trained in Passivhaus design and brings this knowledge to the wider team. Working alongside colleagues, he uses energy modelling to explore how choices about layout, glazing, insulation and construction could improve your home’s performance. We consider these decisions alongside the appearance, feel and practicalities of your home, helping you find an approach that suits your priorities and budget.

Frequently asked questions

Does a Passivhaus need heating?

Usually, yes, but its heating demand is very low. The appropriate heating system depends on the individual design and energy assessment.

Can I open the windows?

Yes. You can open windows as normal. The ventilation system provides fresh air without relying on open windows, which is particularly useful in colder weather.

Does Passivhaus cost more to build?

Higher-performance components, modelling, testing and certification can add costs. Considering these early helps us explore cost-effective choices and balance performance with your budget.

Can Passivhaus principles be used in an existing home?

Yes. They can inform improvements to existing properties. EnerPHit is a related certification standard developed for retrofit projects, where appropriate.

Do I have to pursue certification?

No. We can discuss a low-energy home informed by Passivhaus principles without seeking certification. This is distinct from a certified Passivhaus, which requires independent verification.
