Why participate in the Passive Solar Index?
The most energy-efficient buildings are those designed to harness and retain heat from the sun in the winter, and employ shading techniques to passively keep homes cool in summer. Through the Passive Solar Index program, Ecohome helps designers achieve their performance goals and offers them recognition for their efforts.
Does the world need another home rating system? No, probably not, but this isn't one.
This is a service we provide where building envelopes are optimised to provide a clear sense of how their homes will perform, and where improvements are best made to save money and energy. A typical home in Canada or colder climate zones in the USA will consume over 100 kWh per square meter. To encourage energy efficiency, any home that achieves below 50 kWh will be featured on our PSI pages free of charge, but if you would like to see a Passive Solar home with a Passive Solar Index of only 15 kWh per square meter, take a look at The Edelweiss built by EcoHome here.
