Wow! The first years energy bills from this small office building show that it almost heats itself! Pre-construction calculations showed that the combined heat produced by lighting, computers and other office equipment, and the five or six full-time office staff would almost provide all the heat needed to keep this building warm on all but the coldest days of winter. The resistance electric wall heaters in each room come on for just a few minutes each morning as the staff is arriving at work, then the lighting and other equipment take over to keep the building warm throughout the day. The heat is turned down at night by set-back thermostats, so no energy is wasted. The expansive east facing windows help the morning sun warm the building, then the relatively bare south and west sides keep the sun from over heating the building in the mid-day and afternoon.offerings.
