Occupant Behavior puts a kink in the calcs

From Martin Holladay on Green Building Advisor in an artivle titled “Occupant Behavior Makes a Difference” Engineer things all you want but when you put Americans into a house the metrics tend to change. This is pretty funny.

It didn’t take long to figure out what was driving the high energy bills. “There is a very large plasma TV, plus a second TV on the porch,” said Panish. “There is a DVR. The two TVs and the DVR use 600 watts when they’re on and 100 watts when they are off, and the TVs are on for an average of 6 hours per day. The loads for entertainment and computers are high. There is an old freezer in the basement. There is a basement dehumidifier. The lighting load is 600% of what was predicted. It seems as if all the lights in the house are left on all the time.”
