Abstract
Passive housing is a combination of technological products which base on building energy saving concept, and it makes full use of solar energy, geothermal energy and other renewable energy to reduce the consumption of primary energy used in heating to 15 kw/h·m2·y, however, the energy consumption in low-energy house, which has equipped with various kinds of energy saving technologies, is about 30-75 kw/h·m2·y, thus, passive house has a better performance in energy saving than low-energy house. Energy saving technologies suitable for passive house and low-energy house in hot summer and cold winter area are proposed in this paper through introducing the contribution Germany has made and development of technology in passive housing, using its advanced technologies and practical experience ins passive house as reference and taking Chinese unique climate condition, building types and residents living habits into account.
