Abstract
The aim of this study is to verify qualities of indoor thermal environment and heating energy consumption through this research on highly insulated buildings introduced reduction systems of fresh air load in cold regions. The research objects are two government offices for outside insulated RC buildings newly built in Obihiro City and Hakodate City. We consider the temperature characteristics on effects of high heat insulation and thermal storage in buildings, and the heating systems and control techniques on operations for highly insulated buildings. Also we consider the effects of energy reduction and usefulness on introductions of reduction systems of fresh air load. Based on what we have learned through this research, we discuss the subjects and suggestions for highly insulated buildings in cold regions.
