Construction starts on Passivhaus homes
Maccreanor Lavington-designed all-affordable scheme set to cut bills by 80% a year
Report from – Jo Smit
Construction of the UK’s first all-affordable Passivhaus certified housing development has got under way in Rainham, Essex.
Rainham Passive Housing scheme, designed by architect Maccreanor Lavington, will comprise 51 affordable rented homes with a mix of one, two, three and four-bedroom units. All the homes are designed to comply with Lifetime Homes, the London Housing Design Guide and Code for Sustainable Homes level 4. Developed by Circle Housing Group and Climate Energy Homes, the project will use the ecoTECH super-insulated timber panel system – for which Climate Energy Homes holds the UK patent – with brick and timber cladding. PRP is project manager and cost consultant on the project.
Working with Passivhaus consultant Peter Warm Associates, the architect has designed a simple arrangement of unbroken terraces, which are deep on plan and so maintain the low ratio of external envelope to floor area. This simple, efficient envelope is key to thermal efficiency and airtightness. The size and position of windows has been considered to balance requirements for good levels of daylight, minimal heat loss and solar gain.
Helen Wilson, group head of energy and green strategy of Circle Housing Group, said, "We are really excited about this new development as it has the potential to reduce our customers’ heating and hot water costs by up to 80% each year.”
