Once upon a time, in a land called Maine, a girl (of a certain age) couldn’t help but wonder, “if you want to reward homeowners for saving energy in their homes, doesn’t it make sense to look at actual energy usage, something that accounts for behavior, as well as structures?” Soon, there were others, too, in lands far to the west and south who shared this wonder, antagonized by a protocol of projecting energy savings based on structural details. Perhaps modeling needs to be in line with actual utility bills and oil deliveries, and those actuals would better reflect energy savings, and more realistic carbon savings. Perhaps there needs to be a “before and after improvement” verification of savings, and a way for everyone to keep track.
The girl (of a certain age) checked out of the world for a couple years, to Southeast Asia where she found her bliss in colorful silk, and when she returned to the world of energy, she met a man who had a vision, in a land called New York. And he was called Tom. And he introduced her to people paving a path of realistic energy projections. And they were called Snugg Home.
