European certification of HVAC products can provide EPC input data

Systems providing space heating, ventilation, space cooling and/or domestic hot water (HVAC) to residential or commercial buildings are playing a major role in the building energy performance. Eurovent Certita Certification manages a voluntary certification of the performance of heating, ventilation and air conditioning products, under the European mark “Eurovent Certified Performance”. Such a certification increases confidence in the published performance data of products and provides an easier access to input data for calculation of a building’s energy performance.

The Effinergie approach to ease transitions to new regulatory requirements

Since 2006, the Effinergie certification has been a major market driver in France for energy efficiency initiatives in all building types, new and renovated. It has been a laboratory for the 2012 energy regulation in France, for instance, for the overall primary energy minimum requirements or for the mandatory justification of an envelope airtightness level. In the same vein, the Effinergie+ and Bepos labels operational since 2012 and 2013 experiment new requirements and methods, which will serve for the 2020 revision of the energy regulation.

Building air leakage rate in energy calculation and compliance procedures

Building air leakage rate is taken into account in energy calculations, but mainly with default tabulated values. With tabulated values, there is an option to use measured values instead of more conservative tabulated values. Regarding compliance, usually there is no requirement to measure and verify the building air leakage rate (except in France).

AMA – General material and workmanship specifications

AMA (General material and workmanship specifications) has been used in Sweden for more than sixty years. The different parts of AMA are used as reference documents in technical specifications. Between 90 and 95% of all building projects in Sweden refer to AMA in the contract documents.

French voluntary scheme for harmonised publication of ventilation product data

Fact sheet #03 describes a voluntary scheme defining the data to be announced in the product documentation. The scheme has been launched in 2012 by Uniclima, the French association of ventilation product manufacturers. It ensures that product characteristics are provided under a harmonised form (same physical quantity, unit and assessment method), and facilitates access to relevant input data for the energy performance calculation of a building. The scheme contributes to enhancing the compliance of published data.

Energy labelling of existing buildings and their equipment: new procedures to assess possiblities for increasing energy efficiency while reducing CO2 emission and improving comfort.

Describes best practice for energy labelling for existing residential buildings in four countries. Also describes the specific features of a Belgian procedure for on-site evaluation of both equipment and building envelope. The results can be used by other countries as general guidelines to develop or optimise efficient and effective energy labelling procedures.
