Technical Characteristics

Examples of wall systems: Alsecco (above), Finnforest (below). Certificates: Passiv Haus Institut 2005

A Passive House requires reliable solutions for components of the building envelope and building services systems. The Passive House certification scheme allows the design team to choose products that are accepted as Passive House Components. In addition, European Product approval schemes may be utilized in looking for components with adequate and tested properties.

The heating energy demand of a house can be significantly reduced by improving the thermal insulation level of structures. Heat losses through the structures are the major source of the total heat loss. Ventilation refers to about one third of the total heat loss. A Passive House is an entity where the main benefit of the high thermal insulation level can be achieved only by adequate dimensioning of heating and ventilation systems.
