Beattie Passive Build System is a patented construction method that can be designed to any specification or style using Passivhaus methodology to deliver a complete build system certified by the Passivhaus Institute in Germany; the only company in the UK to achieve this award. A simple and replicable build system that delivers the energy efficiency values of a Passivhaus. The construction forms foundation beams, ground floor, walls and roof all built to form a continuous void. Once in place, flame retardant insulation material is injected into the floor, wall and ceiling cavities, creating one continuous seal. No joints, no leaks. We work from grand designs, housing developments, social, schools and commercial buildings. All can be delivered quickly and at a cost similar to traditional methods but offering huge energy and heat savings, delivering dramatically reduced cost of ownership.
CA Sustainable Architecture divides its time between Architecture, Energy and Code for Sustainable Homes assessments and Research.
