Abstract
For the purpose of grasping operational condition, air conditioning load and the energy consumption, we have conducted the observed survey of the environmentally conscious building completed on 1999. This study has been done for a year of 2007. Throughout the year survey, especially the middle season, we found out the natural ventilation has been fully utilized. The following report shows our designed facility has been functionally operated as energy consumption building and actual survey number express the less operation time and energy consumption for the air conditioning.
