Passive House Energy Efficient Components

A different type of material and technology database that exists in Europe is that of the Passive House Energy Efficient Components. Through its very nature the extremely energy efficient building of a Passive House needs highly energy efficient building materials and systems. Such materials and technologies are however very difficult to assess.

The energy-efficiency, durability and the necessary energy parameters of materials and technologies are however frequently not accurate enough or in some cases even unrealistic as they have for example not been certified to realistic energy efficient criteria. A reliable energy consumption calculation as well as LCA is not possible with the available data.

In addressing this the Passive House Institute, an independent certification authority, has developed standards to test and certify materials and technologies under realistic use for their suitability for use in Passive Houses. Products that carry the Certified Passive House Component seal have been tested according to uniform criteria; they are comparable in terms of their specific values, and are of excellent quality regarding energy efficiency. All components are certified and provided with labelling that they are Passive house conformant. Certified components include:

  • Walls and building systems
  • Low thermal bridge solutions
  • Ground slab insulation systems
  • Certified window frames and glazing
  • Doors
  • Ventilation systems
  • Compact heat pump units
  • Construction systems without thermal bridges
  • Waste water heat recovery
  • Air tight systems

The use of such materials and technologies dramatically eases the work load of the designers as well as the constructors as it helps to ensure that the buildings have been built according to highest standard.
