Sustainable Housing DevelopmentBridgwater, Somerset
This is the first private sector sustainable housing development in the UK to be built to this level. The houses achieved Level 5 of the Code for Sustainable Homes (CfSH). The developer commissioned O2i Design Consultants to develop the detailed design scheme and draw up the building regulations plans.
The five timber-framed houses stand on a brownfield site. The houses incorporate renewable energy and sustainable construction techniques. Three terraced three-bed homes and two four-bed detached houses form a secure courtyard space, to complement the conservation area. The dwellings have a minimal impact on the environment. Onsite energy production generates 100% of the minimal electricity demand for lighting and MVHR fans. Wall and roof insulation U values of 0.11 W/m2K are a 100% improvement on the ‘dwelling emission rate’ of a house built to current Building Regulations.
Oxford Brooks University Research Unit was commission by the Good Homes Alliance to carry out an assessment of the houses’ performance against the design criteria alongside a post-occupancy study. The development won the Regen SW Best Sustainable Development award; featured as one of four national case studies of sustainable architecture in a DCLG Sustainable Housing publication (Code for Sustainable Homes) and recognised in the South West LABC Building Excellence Awards for Best Sustainable Project in 2011.
