If you are looking for a passive house architect to design you a sustainable building, eco house or passive home, you may wonder what is the difference in meaning between architecture that is ‘Passivhaus’ and ‘Passive House’?

In a unique extension of the indepth, remote energy monitoring of the low cost, passivhaus Larch and Lime Houses in Ebbw Vale, the keys to the houses were handed over to the two lucky families who have won a competition to live in the houses rent free for 12 months whilst participating in the live monitoring process.

On Sunday, some of the UK's leading building performance experts joined Dr Wolfgang Feist and Witta Ebel of the Passivhaus Institute, visiting some of our latest domestic and non-domestic Passivhaus projects in London. The purpose of the visits was to review the last 12 months of data analysis and inspect the live data that is being produced, in order to check if Passivhaus is working in the UK climate.

Justin-Bere-BRE-Passivhaus-at the-Innovation Park

Jaya Skandamoorthy (BRE director of Enterprise and Innovation) attended a meeting at bere:architects today with Virginia Cinquemani (BRE Innovation Park) in order to establish the building and training and disemination programme around our competition-winning Chestnut House low cost passivhaus prototypes at the Watford Innovation Park.

The semi-detached pair of houses, designed in collaboration with the Prince of Wales' Foundation for Building Communities, will be completed in time for a ministerial opening in September 2012.


Cold Weather and the Elderly: As the cold weather bites, vulnerable and elderly people are the ones who will suffer the most, and they are the least able to fight the cold, damp conditions.

Rising Energy Prices: With rising energy prices, more and more people are slipping into fuel poverty.



Last Tuesday morning we visited our ‘towards Passivhaus’ Retrofit-for-the-Future project at 3 Passfield Drive in East London to take some thermal images of the finished retrofit. We wanted to take advantage of the cold snap that is being experienced across the country to check the thermal performance of the building.

At 8.30am on Tuesday morning the outside temperature was 1.5°C. The thermal images of the front facades of Passfield Drive, shown above in Fig 1, are a powerful visual indication of just how much energy this retrofit is saving.

The Chestnut House Village Square Render

It has been announced today that The Chestnut House, our Passivhaus designed in collaboration with the Prince's Foundation for Building Community, has been chosen as the winning pair of houses to be built at the BRE’s Watford Innovation Park. The Scottish based PassivCollective’s Passivhaus design has been chosen for the BRE’s Ravenscraig site in Scotland.

Larch and Lime Houses

The Green House Competition has been launched to find people to live in and assess the Larch and Lime Houses at the former steel works at Ebbw Vale in South Wales, designed by bere:architects’ and built by United Welsh under a competition administered by the Building Research Establishment Wales.
