NEW YORK —The nonprofit Urban Green Council (UGC) is warning builders that choosing subpar materials to meet energy performance standards may actually consume more energy than planned.
According to “High Cholesterol Buildings,” a report from the New York-based UGC, the envelope (walls, windows and roof) of today’s average building doesn’t insulate very well, and some are “outright terrible, creating a devastating tax on our energy resources.”
