MULTI-elektro provides preparing energy performance certificates for new buildings, reconstructed buildings and buildings being subject of sale. We have been preparing certificates since the Directive of the European Parliament and the Council of Europe of 16 December 2002 concerning the energy quality of buildings became effective in Poland, i.e. since 1 January 2009.

A certificate may be accompanied by the infrared analysis of a building that is the subject of calculations.


What is an energy performance certificate?

This is a document that specifies the demand for energy necessary to meet the operational needs of the building or premises, i.e. the energy used for heating, hot water, ventilation and air conditioning, and for public buildings, also the lighting. In energy performance certificates for industrial buildings and warehouses, the amount of energy supplied to these buildings for the process and production purposes is not incorporated. The certificate examines the energy demand resulting from the intended use and the standard of the building and its installation systems, i.e. based on its fixed, objective characteristics and not on the measurement of energy consumption, since it is difficult to objectively evaluate the way the user uses the building.

The obligation to have an energy performance certificate of a building, a dwelling unit or a part of the building constituting an independent technical and commercial unit is dictated by the European law. Obligations of the Member States of the European Union provided in Directive 2002/91/EC on energy performance of buildings have been introduced into Polish law by an amendment to the Construction Law. The purpose of the obligation to prepare certificates is to promote energy efficient construction and increase public awareness of the ways to achieve energy savings in buildings. With the information provided in the certificate, an owner, a tenant or a user can determine the approximate annual energy demand, and thus maintenance costs associated with the energy demand.

The basis for the preparation of an energy performance certificate is the energy performance analysis of the building, as defined in the technical documentation for the existing building or if there is no technical documentation, it is determined by a technical and construction survey. An energy performance analysis is a collection of data and energy indicators of the building for design energy demand of the building for central heating, hot water, ventilation and air conditioning, and for a public building, also the lighting.
