A super insulated test house was constructed in Shinshu University of Nagano city. This house was designed with zero heating load concept and its heat loss coefficient is 0.72W/m2K. The thermal environment and energy consumption were monitored for one year. Measured results reveal the possibility for no energy consumption for space heating with both high thermal performance of envelopes and generated heat gain from occupants, lights and so on. Also it is shown through field measurement and numerical analysis that super thermal performance with solar shading and cross ventilation conduce the decrease of energy consumption for space cooling.
