ECD ARCHITECTS: A NEW MODEL FOR TACKLING ESTATE REFURBISHMENT AND FUEL POVERTY | 21 COLLABORATE, MEASURE, LEARN, IMPROVE A key objective of this project was to measure actual performance to both inform and improve future projects. Both PCC and ECD sought to collaborate with others to understand the outcomes of the project and disseminate these more widely. PCC invited Southampton University (Sustainable Energy Research Group) to undertake pre-retrofit studies to establish the extent of fuel poverty and later to measure the thermal performance of the completed building in both summer and winter heating seasons. ECD invited London School of Economics (Housing & Communities) with Rockwool to undertake detailed surveys of existing residents before, during and after the works to understand the challenges and benefits of working with residents in-situ and what impact the project has had on their lives. With Keegans cost consultants ECD also sought to measure the financial cost of achieving EnerPHit and proved that this could be recovered through reduced running costs within the planned 30 year investment. Finally, ECD introduced BRE as UK partner of the Passivhaus ‘EuroPHit’ programme. Wilmcote House subsequently became the EuroPHit UK case study which resulted in additional funding for training and technical support. Throughout the project both PCC and ECD have supported many housing professionals and construction students in the study of the project with several tours of the building both during the works and after completion. As a result, Wilmcote House has won several awards and has become the benchmark for future housing retrofit in the UK and remains the largest occupied building to target EnerPHit in the world.
