Method Architecture is Edinburgh based practice with a focus on domestic architecture. Designing to Passivhaus standards is part of an ecological approach to architecture. As the most rigorous assessment of energy in use for buildings this is key tool to making buildings comfortable while reducing the environmental impacts of construction. In the context of a climate emergency, architecture could be defined as the responsible use of the world’s finite resources for the greatest benefit of society. Passivhaus brings some scientific rigour to a profession based in art, and gives a reliable metric for the energy performance of buildings.
