    Abstract

    In January 2014, “Energy Management House” was held in Tokyo, Japan. It is a net Zero Energy House (ZEH) competition, or a kind of Japanese Solar Decathlon. Waseda University designed a ZEH titled Nobi-Nobi HOUSE, which showcased various advanced technologies and ideas. We reconstructed this ZEH in Shizuoka and measured the thermal environment, light environment, and energy balance in the two seasons following the competition. Measurements indicated that autocalved lightweight concrete (ALC) panels used for interior walls have a heat storage effect and that the room air conditioner consumes a lot of the energy in summer. Therefore, operations connected with the thermal environment and equipment by home energy management system (HEMS) is essential for attaining ZEH status. This paper will present the concepts of the Nobi-Nobi HOUSE and the results of the field survey.
