When selling or renting/leasing your property or a commercial building, a consumption or energy requirement certificate must be presented.

Which energy certificate is required?

​

The consumption-oriented energy certificate ( consumption certificate ) is generally permissible for residential buildings with at least

five residential units and for all residential buildings built after 1977, and the thermal insulation ordinance

from 1977 already comply.

​

The needs-oriented energy certificate ( requirement certificate ) is mandatory for all residential buildings with up to four residential units that were built before the Heat Insulation Ordinance of 1977 came into force.
