How does it work

Efficiency improves comfort

This standard is leading in low-energy constructions. The passive house needs barely 10% of the energy used by typical European buildings, which means it would save energy by 90%. Owners of passive houses do not care about the increase in electricity prices.

Passive House explained in 90 seconds
  • The passive house requires less than 15 kWh / (m²yr) for heating and cooling.
  • Cooling and heating is limited to a maximum of 10 W/m2
  • The basic use of energy should not exceed 120 kWh / (m²a)
  • Passive houses must be impermeable by changing air rates that are limited to n50 = 0.6 / h
  • In places with warmer climates or during summer, high temperatures should not occur more than 10% of the time.index
  • Passive house is a sustainable building and a concept that provides affordable, with high quality, as well as comfortable and healthy living conditions. Their principle of work is easy to understand.
  • As new buildings are significantly aitthighter, ventilation through joints and cracks alone, is not sufficient to provide fresh air inside. With the recommended opening of the windows, the problem will not be solved either. Fresh air is not a matter of comfort, but something that is essential for a healthy life. Therefore, the ventilation system is a key technology milestone for all future residential buildings.
  • Although these systems require additional investment at the start, they ultimately contribute to much greater energy savings, of course, certainly if it is a ventialtion system with proven quality. The quality ventilation system in Passive Houses will reduce the cost of each building.
  • This is actually the concept of passive houses: Since the fresh air from the outside should certainly supply the building inside, why not use this air for heating? Without additional air quantity, without air recirculation, without any unpleasant noise and draft. In this way, the ventilation system is paid off much more.
  • This concept works in very well isolated buildings, as Passive Houses are. Or professionally speaking: The heating transfer must be smaller than 10W/ m², to ensure that the required heat can be provided from the fresh air.
