A passive house is a building which is warm and cosy in winter and comfortably cool in summer. The construction is air- and windproof, thermal bridge free, the thermal insulation is particularly good, and it has also a heat recovery system and disc glazing. The construction of a passive house is very compact and if possible south facing. These houses use up to 90% less energy than conventional constructions, and expend a minimum amount of energy. Passive houses are constructed according to state-of-the-art building physics: they are airtight, particularly well insulated and use natural resources like sunlight and terrestrial heat for energy generation and calorific requirements. A passive house is the most intelligent answer to the difficult situation in the global energy sector. Due to the passive house’s minimal need for fossil fuels, it has its share in reducing CO2 emissions globally and therefore also prevents damage to our climate.
The passive house is a substantial development for the protection of our future and our living environment from both an ecological and economic point of view.
