Our award winning social housing retrofit, carried out with Southern Housing under the Technology Strategy Board's Retrofit for the Future project, used passivhaus 'fabric-first' measures, together with a very efficient heat recovery ventilation unit. Monitoring of the house shows that it has been transformed from a cold house running with condensation and blighted by mould growth and asthmatic indoor conditions, to a house that has absolutely optimal indoor comfort and health conditions in winter and summer.

To see conditions before the retrofit, look at this short film: http://bere.co.uk/berearchitects-retrofits-future-episode-1


Optimum comfort and health conditions last summer too.
