A tale of two towers... Emma Osmundsen, Chair of @passivhaustrust.bsky.social tells of a contractor delivering two housing blocks in #London. One is PH certified, the other is not... and the certified project is being delivered for less cost! Contractors now requesting #Passivhaus! #UKPHC25 #Belfast
"Sustainable building and scale building are not mutually exclusive strategies".... at the opening session of the #ukphc25 in #Belfast. Looking forward to a full day hearing about the #Passivhaus projects and strategies at the forefront of building decarbonisation.

Our conference paper has won the Best Theme Award at the International Retrofit Conference! Co-authored with Dr. Haniyeh Mohammadpourkarbasi from @liverpooluni.bsky.social School of Architecture, we have developed a heritage retrofit methodology for decarbonising listed and historic properties.
Exciting to see vacuum glazing installed at Central Lodge, a Grade II listed building we've supported with #EnerPHit design. Our client Andy explains how the vac glass has made #Passivaus possible on his property.
