About the Project
Designed by Emmett Russell Architects working with Passivhaus Designers Greengauge is part of a wider project that is being undertaken by Bristol City Council to build new build council housing on small sites on existing land owned by the housing department. Housing developments on eight of these sites are being built to Passivhaus Standards, three of these have been designed by a team led by Emmett Russell Architects and a further five have been designed by Gale and Snowdon Architects.
The projects were launched during Bristol’s tenure as European Green Capital. The city aimed to achieve a “Low Carbon City with a high quality of life of all” and it was important that the new council housing produced by the city lived up to these ambitions.
The developments are in Henbury and Brentry on sites previously occupied by garages to the rear of existing post war council housing. Most of the existing council housing in these areas is family housing, typically three bedroom terraced or semi-detached houses. These new housing projects will provide twenty smaller units with a mix of one-bedroom flats and two-bedroom bungalows. One of the aims of the project was to provide housing that would be suitable for existing tenants who wanted to downsize. It was important that the projects had a simple and robust fabric-first approach to reducing energy use and were easy to use and maintain. The Passivhaus approach offered a way to reduce energy use, address issues of fuel poverty and provide a comfortable internal environment with good air quality.
As well as these three projects the council is developing a second phase of Passivhaus housing on a further five sites in Lawrence Weston on the North West fringe of the city. Running the two projects in parallel will allow the council to test out two very different approaches to Passivhaus construction, one based on timber frame and the second using extruded clay blocks. The lessons learned from these projects will help inform future phases of new-build council housing.
In designing this project we have have tried to use standard conventional timber frame construction as far as possible in order to keep costs down. Additional insulation is provided outside the studs to improve ‘U’ values and reduce cold bridging. Airtightness is dealt with internally through a taped membrane with a service void to avoid penetrations.
