S.L. 623.1 Art. 12Energy performance certificates (EPCs).

(1) The Building and Construction Authority shall provide all necessary measures to establish and maintain a system of registration of the EPC. The EPC shall include the EPB and reference values such as minimum energy performance requirements, in order to make it possible for owners or tenants of the building or building unit to compare and assess its energy performance.

(2) The EPC may include additional information such as the annual energy consumption for buildings and the percentage of energy from renewable sources in the total energy consumption.

(3) The EPC shall include recommendations for the cost-optimal or cost-effective improvement of the EPB or building unit, unless there is no reasonable potential for such improvement compared to the energy performance requirements in force. The recommendations included in the EPC shall cover:

(a) measures to be carried out in connection with a major renovation of the building envelope or technical building system(s); and

(b) measures for individual building elements independent of a major renovation of the building envelope or technical building system(s).

(4) The recommendations included in the EPC shall be technically feasible for the specific building and may provide an estimate for the range of payback periods or cost-benefits over its economic lifecycle.

(5) The EPC shall provide an indication as to where the owner or tenant can receive more detailed information, including as regards the cost-effectiveness of the recommendations made in the EPC. The evaluation of cost effectiveness shall be based on a set of standard conditions, such as the assessment of energy savings and underlying energy prices and a preliminary cost forecast.

(6) In addition, the EPC shall contain information on the steps to be taken to implement the recommendations. Other information, such as energy audits or incentives of a financial or other nature and financing possibilities, may also be provided to the owner or tenant.

(7) Certification for building units shall be based:

(a) on the assessment of an individual building unit when it deals with residential buildings;

(b) for all other non-residential uses, delineation shall be based on use factor or ownership.

(8) Certification for single-family houses may be based on the assessment of another representative building of similar design and size with a similar and actual energy performance quality if such correspondence can be guaranteed by the expert issuing the EPC.
