Passivhaus design by our Passivhaus trained designer and certification via independent certified assessors.

Design and Certification for Passivhaus runs throughout the planning and construction process. Our designers work closely with the Passivhaus Institute accredited certifier. We use the Building Research Establishment at Watford as our independent certifiers.

We ensure we build to Passivhaus principles using Passivhaus methodology and the Passivhaus Planning Package Software.
