Insulating UK’s Biggest Passivhaus Social Housing Scheme

Goldsmith Street Norwich

We are delighted to announce that the ambitious development of Goldsmith Street in Norwich has been shortlisted for the 2019 Royal Institute of British Architects (RIBA) Stirling Prize. The unfinished development has been recognised for winning the RIBA East Award 2019, RIBA East Client of the Year 2019 for Norwich City Council, RIBA East Sustainability Award 2019, CPRE’s Green Build Award 2018 and won overall Housing Design Awards 2019.

This development include many different unique aspects including the rooftops that are carefully angled to ensure that each terrace prevents sunlight from blocking the windows of the rows behind.

Devana Insulation installed Cellulose fibre insulation to a Passivhaus standard, and in fact, was integral to the overall standard of the scheme. Our installation ensures tenants had a stable temperature in their homes throughout the year and therefore can reduce their fuels costs.

Due to fuel poverty, the Norwich City Council requested to change to Passivhaus halfway through the project. The NCC wants to eliminate high heating demand, and Passivhaus standard allows an energy savings of 70% on annual heating bills, which suggests that heating bills should be no more than £150 a year for tenants.

With many Passivhaus projects, airtightness is imperative. At Devana we pride ourselves in our Cellulose Insulation and guarantee that it is 36% more airtight than fibreglass, which can leave homes 4 degrees warmer overnight. The insulation requires 26.4% less energy in comparison to fibreglass.

We are very proud of the Goldsmith Street achievements and recognition it has received in the community for its special work. Devana is pleased to be a key contributor to the largest 100% Passivhaus, 100% social rented housing scheme in the UK.
