By using certain principles for building aspects. The passivhaus technique achieves its standards by improving on many aspects of designing and building, particularly:
1. Passive Solar Design: This entails using naturally available sunlight, the suns’ daily and annual cycles to maintain a comfortably warm home without using other heating and ventilation system. This is done by building compact structures, window orientation, using lightweight materials and other techniques.
2. Superinsulation: The walls, floor and roof of a passive house are highly thermal insulated to prevent heat from escaping. Most houses have some form of insulation, however, they will depend on traditional temperature control devices to maintain constant temperatures throughout the house. Passive houses are superinsulated, such that the walls themselves are made up of insulating materials. Because of this, there are no thermal bridges, and there needs to be no external insulation of any kind.
3. Advanced Window Technology: Windows play an important role in designing passive houses. Window placement, size, alignment, material and design help to increase natural lighting in the house without adding to the heat or using electricity. Windows for passivhaus are differently manufactured and are made with extremely thermal resistant. The glass also is generally filled with argon or krypton gas which reduces heat transfer either ways and absorbs UV rays.
