2) Passivhaus Sustainable Homes
Passivhaus, or Passive House, is a highly effective energy and comfort standard for sustainable home design. Passivhaus standard buildings use lots of insulation, fresh air, natural daylight and the sun to create high performing homes that maintain a constant temperature, all year round.
It’s an exciting alternative to regular heating. Instead of standard, inefficient boilers and radiators, a passive house building is fitted with high levels of insulation and a simple, low energy ventilation system, meaning you can avoid heating even in the depths of winter!
At the start of a project we carefully analyse your site, taking full advantage of the site’s natural features when we design your dream home. We work closely with expert energy assessors to provide virtual modelling of your new eco house design, enabling us optimise the building specification and achieve Passivhaus standard certification. Our approach means that a passive house design can create amazing buildings, that are low energy and cheap to run.
The benefits are:
- A cleaner, healthier environment with improved air quality
- A large reduction in energy with improved air quality
- Extremely low energy bills
- Airtight, draught free homes – around 20 times more airtight than standard!
3) Materials for your Sustainable Home
At Footprint Architects we like to select sustainable, locally sourced building materials that look beautiful and have low embodied carbon. We prefer to select products that are easy to maintain, last a life time and can be recycled in the future. In recent projects we have:
- Used 100% recycled plastics that are 100% recyclable to create imaginative interiors
- Used low carbon concrete that replaces 80% of the cement with waste bi-products from other industries
- Re-used 52 tonnes of hardwood to create sustainable cladding in our project at Durley Chine Environmental Hub
4) Renewable Energy
Installing sources of renewable energy to your home, such as solar PV panels, solar thermal hot water or air source heat pumps are a great way to reduce your carbon footprint and save on bills. At Footprint Architects we advocate the inclusion of renewable energy sources to all new modern eco homes that we design.
5) Re Use
The idea is simple, demolish as little as possible and re-use the existing structure to reduce carbon emissions. Retrofitting typically involves a significant improvement in the thermal performance of the existing building fabric to create a warm and comfortable home.
At Footprint Architects we use our expertise to carefully and sensitively design relevant energy efficiency improvements to existing properties, making them fit for modern living whilst reducing energy consumption.
FAQ: Can You Upgrade an Existing Home to Passivhaus Standards?
Yes, you can retrofit older properties so that they function along the same passive house principles, although it’s not usually possible to reach the same levels of insulation as a new build, significant energy saving of between 75 and 90% are possible.
The Passivhaus Institute does have a separate certification that recognises appropriate retrofitting, this is known as EnerPhit ‘Quality-Approved Energy Retrofit with Passive House Components.’

Five Steps to Designing Your Sustainable Dream Home
A practical guide to creating a home that looks and feels right, while reducing its impact on people and the planet.
Our sustainable homes design guide is a useful starting point, but every site, brief and budget is different. We can help you turn the principles into a practical, low-energy home designed around the way you want to live.
1. Fabric First
Footprint Architects adopt a fabric-first approach to allnew homes that we design. Enhancing the thermal envelope and airtightness is a simple but highly effective way to reduce energy consumption.
- High levels of insulation in the walls, floors and roof to keep the heat in
- Maximising airtightness to reduce cold draughts
- Positioning windows to maximise heating from the sun in the winter
- Using thermal mass to keep homes cool in the summer and warm in the winter
- Orienting homes to maximise shading
This low-tech approach ensures that the buildings we create are easy to use, have low running costs, are simple to maintain, and are healthy environments to live in.
