This study is on the design and evaluation of Zero Energy Solar House (ZeSH) including active solar heating system. Various innovative technologies such as super insulation, passive solar systems, super window, ventilation heat recovery system…etc were analyzed by individual and combination for the success of ZeSH. The ESP-r simulation program was used for this. Simulation results shows that almost 77% of heating load can be reduced with the following configuration of 200mm super insulation, super windows, passive solar system and 0.3 ventilation rate per hour. Active solar heating system (ASHS) was designed for the rest of the heating load including hot water heating load. The solar assisted heat pump is used for the auxiliary heating device in order to use air conditioner but not included in this study. The yearly solar fraction is 87% with a solar collector area of 28 m^2. The parametric studies as the influence of storage volume and collector area on the solar fraction was analyzed.

This study is on the evaluation of KIER Zero Energy Solar House(ZeSH). This ZeSH was designed and constructed for the goal of 70% self sufficiency only thermal loads. Various innovative technologies for reducing thermal load such as super insulation, high performance window, passive solar systems, ventilation heat recovery system , etc are applied in this ZeSH. In this study, the performance of the active solar heating system with geothermal heat pump as an auxiliary energy system and the energy self sufficiency rate are especially analyzed by experiment. Indoor setting temperature of ZeSH is 20℃ throughout the experimental period. As a result, the performance of active solar system is 35 to 40% depending on the various ambient condition and the solar fraction for heating season is about 74%.
