Energy performance certificate for a post-war veterans' house
· updated
Post-war veterans’ houses (rintamamiestalo) belong to the building category (käyttötarkoitusluokka) of small residential buildings (category 1 a-c). The same category also includes, for example, semi-detached houses. When a post-war house or another building in the same category is sold or rented out, the law requires an energy performance certificate (energiatodistus), whose most important piece of information is the E-value (E-luku). From our energy consulting company you can get an energy certificate or, if needed, more extensive energy consulting services, such as an energy efficiency study in which we identify which energy efficiency projects would be financially viable for the building.
Energy class of a post-war house
A building’s energy class is determined by its E-value, and the energy classes are on a scale of A–G, where A is the best and G the worst. For post-war houses and other small residential buildings, the energy class is also affected by the heated net floor area, as shown in the table below. At least for the time being, there are no E-value or energy class requirements for old buildings. It is enough to have an energy certificate prepared in connection with a sale or rental. If you wish, you can read more about the E-value, how the energy class is determined and other aspects of energy certificates for small residential buildings in the article energy certificate for a detached house.

Decree of the Ministry of the Environment on the energy performance certificate of a building (Ympäristöministeriön asetus rakennuksen energiatodistuksesta 20.12.2017/1048), annexes 1-5: energy classes of small residential buildings.
Factors affecting the calculated energy performance, i.e. the E-value
The energy certificate is prepared by an energy certificate assessor in accordance with the decrees and regulations. The certificate records the data used in the calculation that is relevant to calculating the building’s energy consumption. Such data include, for example, the thermal conductivity of the windows/external walls/base floor/roof, the ventilation system and the efficiency of any heat recovery, any self-generated energy, the airtightness of the structures, the type of heating system and the energy carriers used.
