Passivhaus & Sustainability
Since establishing our practice we have strived to produce buildings which achieve sustainable and environmental targets by adopting a holistic approach in terms of design, materials, energy and transport. This has meant minimising heat loss, promoting natural ventilation, specifying natural products with low embodied energy and understanding the lifelong cost of the buildings we design. Our philosophy has been to design flexible buildings of quality which last.
We have applied these principles in the design and construction of our own Studio which was the first commercial Passivhaus EnerPHit project to be certified. Passivhaus is an energy performance standard for buildings which focusses on excellent thermal performance, airtightness and construction quality.
Through the design and realisation of our own award winning Passivhaus building we have gained valuable experience which we apply to our clients projects.
