15-40 Architecture is rooted in a commitment to radically reduce the energy consumption of buildings through a ‘fabric first’ approach.
The 15-40 name is informed by the metric that defines the maximum space heating demand (15 to 40 kWh/m².yr) used in Passivhaus and AECB building performance standards.
15-40 Architecture includes 6 Certified Passivhaus Designers, and we have extensive experience in delivering sustainable new build and retrofit projects using Passivhaus construction methodologies. By coming together from affiliated companies, all with sustainable building experience, we are able to offer clients a greater depth of expertise, combining ideas, knowledge and resources.
