OVERALL AND ZONAL ENERGY END-USE IN AN ENERGY CONSCIOUS OFFICE BUILDING

An office building of unusual design has been monitored for more than three years. Numerous submeters allow tracking of energy end use. The building was designed to make significant use of daylighting, with some passive solar heating, and an emphasis on night ventilation cooling of thermal mass. The overall building end usages are compared to those of three zones of varying orientation, spatial character, size, and population. Insights about daylight-sensing controls of indirect electric lighting, ''task heating,'' and night ventilation of mass and air quality are presented.
