THE PASSIVE HOUSE, A NEW TYPE OF ECOLOGICAL HABITAT

Abstract

A passive house is a habitat which does not provide noxious during the heating time and manages in an intelligent way the energetical consumptions. This house is provided with an integrated waste management and waste-water treatment and it contains external envelopment very well thermally isolated, windows with frame of laminated wood with three layers of glass and an integrated ventilation system. The integrated ventilation system eliminates the polluted air from the building and it passes through a heat exchanger to recover a part of the thermal energy, transferring that energy to the fresh air that comes from outside the mansion. A passive house can be built anywhere since the concept is simple but, at the same time, intelligent. There is a trend of rapid development of the passive houses in all European countries because their governments offer serious rewards to those who build smart on energetic considerations but, especially for the fact that these houses are particularly healthy and environmentally friendly.
The European Union has prepared several Directives, including "The Energy Performance Directive" in which, each Member State must join. These Directives provide obligations for a better thermally isolated of old and new buildings and the trend of the builders is to adopt new technologies to build the passive house.
The Romanian government has to comply with the European legislation trend and, so, it grants subsidies for those who use renewable energy systems in their building.
