Ruth Butler Architects is a member of the Passivhaus Trust.
We are passionate about the benefits of Passivhaus for people and the environment. The standard is central to our approach to achieving excellent internal comfort and energy efficiency. It is complemented by careful consideration of upfront carbon in the materials and construction methods we use.
Our interest in the standard was ignited when designing our own office (and home) – which was completed and Passivhaus Certified in 2015. Post occupancy monitoring and evaluation demonstrates a comfortable environment, and a 34% improvement on the calculated energy performance.
We apply the principles of a fabric-first approach across the full range of projects, including sport and leisure facilities, educational buildings, sensitive conservation and refurbishments.
