The administration has set the goal of cutting national greenhouse gas emission by 26.9% by 2020, relative to the “business as usual” BAU. Passive-Zero energy has become the goal of building energy performance to reduce greenhouse gas emission. For achieving the target to reduce the greenhouse gas emissions until 2020, the passive house technology will be an essential tool on this road. Passive House is a building standard for energy efficiency in buildings. It maximizes building energy efficiency by super insulation, airtightness and heat recovery ventilation system etc. Zero energy building is a building with zero net energy consumption using renewable energies such as solar heat or geothermal. Passive house is a basis for zero energy buildings. Recently there is an increasing interest in passive-zero energy buildings among people and construction companies. In europe, there have been about 27,000 passive house buildings existing in the 10 PASS-NET countries at the end of 2010. It is expected that the number will rapidly rise to 65,000 buildings till 2012. In Korea, there have been about 20-30 passive house buildings since 2005 and many of them are for marketing or experimental purposes. Towards passive zero energy buildings in Korea, first, building materials and components need to be manufactured in domestic. The building component certification system is the basis for the domestic production. Second, the passive house is much more than the sum of its parts. It should be possible to assess the influence of interrelationships and interdependences of the components required in a passive house. Therefore, the certified program for training the specialists might be needed. Third, passive house standard should be adopted to meet our specific climate and residential type. The new construction method should be developed and verified by research and development.
