Whenever possible, we build to the passive house energy standards. We conducted thorough research to find a standard that matches our own passionate commitments to a green and sustainable future, and found it in the Passive House model, the most rigorous energy standard in the world. The Passive House Standard is originally from Germany, where thousands of passive homes have been built over the last decade and a half.  To find out more about the Passive House Standard, click here.
