The purpose of this research is to study design specification toward ZEB for office building in snowy cold cities. By using the BEST program in calculation and adopting DOE, we decide the building specifications that minimize annual thermal load. Next, we examine the equipment specifications that minimize primary annual energy consumption for the minimum thermal load specifications. Finally, we aim to achieve ZEB by introducing renewable energy. As a result, as reduction rate of annual energy consumption for the standard specifications, the minimum thermal load specifications reduce 28.2%, and the equipment standard specifications reduces 54.2%. Moreover, the high-performance specifications reduce 61.6%. By the introduction of renewable energy, it is possible to realize ZEB Ready.
