Compliant and Easily Accessible EPC Input Data

Compliant and Easily Accessible EPC Input Data

Identifying the data required for the Energy Performance Certificate (EPC) is not always a straightforward procedure. There often is a problem of easy access to the required and, most importantly, to the correct input data and, especially for certain aspects or technology areas, this may require a very substantial effort (e.g. the estimation of the thermal bridge effects). Though the performance characteristics of several products are defined in a unique way in the CEN standards, in a number of cases there can be different interpretations of the product data. There is still a whole range of products and, in particular, of systems (e.g. HVAC, control systems, heat pumps, …) for which an unambiguous definition of data is not obvious. This is in particular, but not only, the case for some of the more innovative technologies.

This part of QUALICHeCK focused on analysing information in order to provide guidance for creating the correct technical boundary conditions that will allow easy access to compliant EPC input data. On the one hand, it is important to understand the technical requirements for having a framework that allows compliance. In particular, it is crucial that there is no confusion in the market about which input data have to be provided, otherwise there is no solid basis for an effective sanctioning approach. On the other hand, the insights from these technical requirements are important boundary conditions for establishing an effective compliance and sanctioning framework.

The objective has been to document and build on interesting initiatives that will improve the compliance of input data used for issuing EPCs. This results in more confidence that an effective approach, a shorter preparation time and a large chance for success are possible.

Specific attention has been paid to the technical aspects of handling of products and systems which are not explicitly covered by the calculation methods (often the case for innovative technologies). This provides information about the available input data for these innovative products, in order to help Member States to include them in the EPC calculation methods.

This work has been led by the French Technical Centre for Heating, Ventilation and Air Conditioning appliances (CETIAT).
