The small passive house problem - a solution?

It’s sometimes said to be hard – perhaps too hard – to get a small house to meet the passive house standard.

Deep retrofit brings Victorian home up to Enerphit

There was a time when insulating an historic property meant treading lightly on its building fabric.

But in the end its owner Hugh Whiriskey emerged with a comfortable home with stunningly low annual heating and hot water costs of just over a euro per square meter.

Building a better passive school
