measures not included in the original renovation plan have to be installed. Only churches, museums or protected buildings or those buildings worthy of preservation are exempted from the requirement.

“Cost efficient energy saving measures” are defined as measures that by simple pay back calculation bring at least 33 pct profit over a standard life time (dependent on the type of the measure). The cost efficient energy saving measures are identified by the energy consultant as part of the labelling of a building, see later.

To all buildings (also to small dwellings) there is a requirement to perform cost efficient energy saving measures to the specific component in the case of renovation of roof, renovation of climate shield on external walls, renovation or change of windows, installation of a new boiler or change of heat supply.

EPBD has been the most debated issue during the implementation of the EPBD in Denmark. It was originally planed to implement the 25 % rule for single family houses, too. This was dropped in the late phase of the implementation due to severe problems regarding legal responsibility e.g. to a carpenter asked to retrofit the roofing and knowing nothing about boilers.

Energy labelling of buildings

The requirements regarding the energy labelling (certification) of buildings (Article 7) have been adopted by the Danish Parliament by Act no. 585 of June 24, 2005 on Energy Savings in Buildings (in Danish). Based on the act by Parliament, the Danish Energy Agency has issued Decree no. 1294 of December 13, 2005 on Energy labelling of Buildings (in Danish). Minor adjustments to the original decree are in decree no. 218 of March 20, 2006 and in decree no. 339 of April 19, 2006.

The Danish Energy Labelling Scale

In the new energy labelling scheme, buildings need an energy label: › When they are new constructed or undergo a major renovation › When they are sold › If rented out.

In the case of new buildings, the building needs to have a sufficient energy label (B) to fulfil the energy requirements in the building regulations to be granted a permit for use.

The energy labelling of new buildings is based on a building inspection supplemented with material from building plan and building permit application. The energy consultant ensures that the energy requirements in building regulations have been met by: • verifying that required insulation of technical installations are in order

• verifying that buildings, installations and products have the energy efficiency assumed when building permits were applied for.

The Handbook for Energy Consultants

In the case of existing buildings being sold or rented out, the buildings must have an energy label of not more than 5 years old. This also applies to blocks of flats, where individual flats are rented out or sold. In blocks of flats, the labelling is done on the building, but with an individual sub label for the flats stating the heating demand.
