| Passive House office building certification is based on a standard occupancy level and corresponding internal gains of 3.5 W/m² (the reference area being the “treated floor area” of the PHPP, not the office area). From the PHI’s experience this value represents a typical average, taking into account an improved efficiency of the equipment used. The reasons why the PHI uses standard values for certification are partly to be able to ensure consistency and also because the use of a building is often not permanent and not always prior known.\\ | Passive House office building certification is based on a standard occupancy level and corresponding internal gains of 3.5 W/m² (the reference area being the “treated floor area” of the PHPP, not the office area).

| Swimming pools are a very energy intensive building typology. The energy demand can be reduced significantly by consistently applying the high energy efficiency approach of the Passive House concept. This not only contributes to climate protection but also entails savings for the financial resources of a municipality. | Swimming pools are a very energy intensive building typology.
