Passive low energy consumption building from Germany, is considered to be one of the world's most advanced energy-saving building. Compared with ordinary buildings, the passive low energy house is almost no heat exchange with the outside world, the heat insulation performance is stronger, can save more than 80%. It is mainly through the high thermal insulation, sealing strong building facades and the use of solar energy, geothermal energy and other renewable energy to implement passive heating and cooling, and ultimately to achieve low energy consumption. For Harbin this winter cold, summer is hot, heating cooling consumption large electricity consumption of northern cities, passive and low energy building to promote the construction of not only save the cost of living and can reach the requirements of energy saving and emission reduction.
Passive and low energy building with strict design standards, completely in no heating facilities, or use less energy conditions, using the building natural heat to the indoor temperature reached 20 DEG C to 26 degrees. That is to say, the heating room temperature indoor can not have standards; relative humidity 40% ~ 60%, to ensure the wall condensation and mildew, window surface without dew phenomenon. Such strict design standards, a better solution to the cost of living, energy-saving emission reduction and the contradiction between living comfort.
