The assessment of the different classes is driven by the //total// primary energy demand, as well as renewable energy supply. The higher the achieved level of overall efficiency and of renewable energy generation, the higher the Passive House class. The Passive House classes are assessed using the PER methodology, |

- | ===== Further information | + | Renewable energy generation in the context of buildings is typically assessed based on achieving a “net-zero” or even “positive” energy balance. The intention of these approaches is to generate at least as much energy as is being consumed over the course of the year in absolute terms, i.e. MWh per year. While this initially appears intuitive, this approach presents challenges and can be very misleading: |

Multi-story buildings, however, have a lower impact in terms of space and material use and are therefore advantageous in terms of sustainable housing developments. | ||
- | [[certification: | + | Instead of off-setting energy demand and energy generation, the Passive House concept rates both aspects independently of one another. The energy demand is measured against the value of the service, which is represented by the useful space of the building, the so-called “Treated floor area (TFA)”. The renewable generation is measured against the area that the building occupies |
