Integrated opt

In a traditional strip foundation there is heat loss due to a  thermal bridge down the inner leaf and also through the floor due to poor levels of insulation. Integrated energy's passive strip foundation aims to eliminate this heat loss. It uses lightweight insulated concrete blocks which prevent thermal bridging down the inner leaf; this is evident from the sketch below. It also uses 150mm of insulation underneath the floor slab to prevent heat loss; the end product of this being a strip foundation that can be used in passivhaus construction.
