An organization advancing passive building standards, training and design competitions for very low-energy buildings.
Phius works to advance passive building standards and practices. Its website shares news of a design competition, a self-guided introduction to the basics of passive building and training opportunities for professionals, and it notes the large floor area of projects that follow its standard. Owners in Nashville who want very comfortable, quiet and efficient homes sometimes explore this approach.
We are an independent firm and are not part of Phius. A passive approach relies on careful orientation, a very tight and well-insulated envelope, high-performance windows and a ventilation system that brings in fresh air. We can design with those principles whether or not you pursue a formal program, and we coordinate with energy modelers and consultants if you want verified results.
