ROCKWOOL EnerPHit deep retro-fit for Portsmouth high rise social housing

Refurbishment to the rigorous EnerPHit standard has commenced on three, 11-storey social housing blocks at Wilmcote House in Portsmouth, the retrofit equivalent of Passivhaus standards.

Portsmouth City Council is undertaking a deep retrofit of the maisonettes constructed in 1968 with the aim of lowering heating demand by 90% and extending building lifetimes by at least 30 years.

Research by the LSE into the refurbishment of three 23-storey tower blocks at Edward Woods estate in Shepherds Bush proved invaluable in planning the Wilmcote House project. Among the most significant lessons from the LSE reports - High Rise Hope and High Rise Hope Revisited - was the importance of communication with residents. Residents of Wilmcote House were fully consulted on the refurbishment proposals via a series of open days and feedback sessions and ROCKWOOL will again work with LSE to record and assess the social outcomes of this project.
