Go Bullfrog!
I am a Bullfrog customer because, while reducing energy loads from buildings through design is part of the solution, it is not the whole solution. Consider that when we add Photovoltaics to the roof of a high-performance office building with the best envelope we can design, they can only provide power for about three stories below. Technology may improve, but it is unlikely that on-site power will be the answer for urban areas. We don’t want low-rise cities that go on for miles and miles!
We need the electrical grid and we need renewable energy sources to feed the grid.
Recently I was interviewed by Bullfrog. Check out my Bullfrog Customer profile here:
