According to the act on construction law, from 1 January 2009, the Energy Performance Certificate is obligatory for building being given for
occupancy
, sold or rent, modernized or rebuilt, if
any change in the building’s energy profile (characteristic???) was made.
The Energy Performance Certificate can be issued only by energy auditors. On the basis of the energy characteristic, which is specified in the construction project or determined during
construction inventory for existing buildings, an integrated characteristic is made.
The energy characteristic is the collection of data and energy factors regarding calculated energy requirements for heating, hot
water, ventilation and cooling for residential buildings, and lighting for
public utility buildings.
The energy classes for buildings by Association for Sustainable Development of Poland:

45 do 80
|
Medium-energy efficient
|
80 do 100
|
Medium-energy-intensive
|
100 do 15

150 do 250

The Energy Performance Certificate of a building or residential premise will show, how much energy is needed by building or residential premise during the year. This amount is defined by an energy performance factor EP [kWh/m2/a]. Additionally certificate contains possibilities of upgrading, which will reduce energy consumption.
The certificate must be renewed, after its expiration date (certificate is valid for 10 years), or earlier, if
any change in the building’s energy profile is made.
