- | 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: | + | Renewable energy generation in the context of buildings is typically assessed based on achieving a “net-zero” or even “positive” energy balance.

+ | 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 and that is therefore longer available for other uses: the “Projected building footprint (PBF)”. This approach of independent assessment of the efficiency level (with respect to the living area) and the energy generation (with respect to the projected footprint area) encourages optimised solutions for both parameters. Regardless of whether the building is a bungalow or an office tower, it is ensured that the energy input needed for health and comfort is low and the energy output with respect to the locally available renewable resources is high. Bungalows will automatically become “plus-energy” houses in many cases, whilst high-rises will not be penalised for not achieving “net-zero”. | ||

- | The sun and wind provide primary renewable electricity. Some of this electricity can be used directly. However, storage capacities are necessary for transferring surplus energy to time periods with lower energy gains. These supply secondary electricity as required, and this is associated with losses.
