Energy Certificates

The EPC is the document that describes the energy characteristics of a building. It is a means of control that summarises the energy performance of buildings with a ten-letter scale (from A4 to G). The Italian Leg. Decr. No.63/2013 (formerly called EPC) introduces the obligation to present the Energy Performance Certificate in 2013.

Besides being compulsory, this document is useful for providing information regarding energy consumption and for clarifying the actual value of high energy saving buildings. The certificate shall be valid for 10 years.

CHP Engineering has been issuing Energy Performance Certificates for trade purposes since 2009 and for rental since 2010. The studio can rely on its accredited experts with specialist competence in the field of energy efficiency.

At present, CHP Engineering can issue Energy Performance Certificates for the following Regions: Emilia-Romagna, Veneto, Lombardy, Piedmont, Trentino, Sicily and Friuli-Venezia Giulia.

The EQC is the document that summarises the energy characteristics of a building. It contains the class to which the building corresponds and its primary energy demand.

The EQC differs from EPC for the following aspects:

• It can be drafted also by a qualified technician who has been involved in the work of the building to be assessed, whereas in the case of the EPC the energy certifier is a subject unrelated to the other stages of the design and implementation process, since it has a role of “tester”
• It does not provide for the allocation of an energy class, but only a “proposal”
• It shall be handed to the Municipality, whereas the EPC to the Region

According to Art. 3, second subparagraph, of the Italian Leg. Decr. No.192/2005, the EQC is mandatory in the following cases:

• Newly constructed buildings
• New systems installed in existing buildings
• Global redevelopment of the building elements constituting the outside of existing buildings with a useful floor area exceeding 1000 m2
• Demolition and reconstruction during extraordinary maintenance operations of existing buildings with a useful floor area exceeding 1000 m2
• Full application, but limited to the only enlargement of the building in case the enlargement itself is volumetrically exceeding the 20% of the whole existing building.
• Replacement of heat generators

CHP Engineering is responsible for issuing the Energy Qualification Certificate for various types of buildings.
