Why Energy Performance Certificate?


Buildings account for about 40 percent of energy consumption in EU countries. The

Energy performance certification is based on an EC directive. The law on energy performance certification of buildings was adopted in 2006. Sweden’s energy objective for homes and premises is that energy consumption in 2020 shall be 20 percent lower than it was in 1995.


The overall purpose of energy performance certification of buildings is to be economical with energy and to promote sustainable development. Aiming to reduce emissions harmful to the climate and to our living environment is also a reason, as is getting a good grip on how to save money to deal with the effects of sharply rising energy prices.

An energy performance certificate describes how effective a building is from an energy point of view. It also makes it possible to compare it with similar buildings.

In connection with the certification, you will also find out whether the building can be improved, how energy consumption can be reduced and the operating costs brought down. If the measures are carried out the building might also increase in value.


   Why is the energy performance certificate advantageous for you as a building owner?

It shows how your building “feels”.

– It notifies you of important examinations, for example, ventilation and radon.

– It provides you with recommendations for cost-effective improvement measures that will contribute to the well-being of you and your building.

– It constitutes a documentation basis when you wish to carry out improvements and perhaps apply for grants/state subsidies.

– It provides you with reference values so that you can compare your building with similar buildings.

– It contributes to a sustainable society, if the recommended measures are carried out.


Who does what?

YOU will only need to perform a single “triple jump”. By that you save – energy, environment and money.

You MUST : collect – contact – put up.

  1. Collect the building records having bearing on the use of energy*.
  2. Contact an independent expert. Accredited experts to perform an energy declaration are listed on
  3. Put up the clearly visible summary of the energy performance certification in the building’s entrance or reception.


The result lasts for ten years! This is how long the energy performance certificate is valid. But when your technology has improved, you can try again and go further.

You are allowed to perform an energy performance certification whenever and as often as you wish.


  • Is experienced and trained for his task.
  • May request additional information from you.
  • Will inspect your house if there are measures available to recommend or if there are no records available in order to make an expert judgement.
  • Has access to reference material and compares your building with similar buildings.
  • Prepares an energy performance certificate for each building in question.
  • Notes whether compulsory ventilation controls and radon measurements have been carried out.
  • Registers the energy performance certificate electronically in the register at the National Board of Housing, Building and Planning.
  • Sends you a copy of the certificate together with recommendations on measures that effectively can reduce your costs.
  • Simultaneously sends a summary for you to put up.


What can be made more energy efficient?

Improvement measures can include:

– heating system adjustments

– Computer-controlled heating

– Heat recovery

– Heat pumps

– Alternative energy such as solar collectors

– More efficient fans

– Demand-controlled ventilation of premises

– Low-energy light-bulbs, fluorescent lighting

– Time or attendance controlled lighting

– More efficient tumble-driers

– Supplementary insulation of e.g. attics

– Sealing around doors and windows

– More energy efficient windows

– Adjustment of water temperature

– Low-flush water taps

– Adjustment or replacement of thermostats

– Time control of engine heaters

– Training of management staff

– Information to tenants

The National Board of Housing, Building and Planning has put together fact sheets on energy efficient measures.

In certain cases you may also receive financial support. Since December 8,

2008 the government has implemented a special tax reduction for housing improvements or maintenance and for additions or alterations to houses older than 5 years (ROT-avdrag).

Additional information is available on Other subsidies are granted for e.g. installation of solar heating or switching from direct electric heating. Visit for details.
