Bright built barn

Here’s a house that announces its energy efficiency (or lack thereof):

With large intentions, its mission is to demonstrate an alternative method of building that allows levels of flexibility and sustainability beyond the reach of typical residential construction. This building requires NO FURNACE, even in Maine, and provides owners with real-time, easily understandable feedback of energy use through its “mood ring” LED fixtures.

The BrightBuilt project is unshakably committed to two overarching concepts:
Sustainability as a goal, and
Open Source Collaboration as a method to reach that goal.
