Gutachten zur Umsetzung von Artikel 14 der Richtlinie über die Gesamtenergieeffizienz von Gebäuden

Article 14 of the Energy Performance of Building Directive (2010/31/EU) requires a regular inspection of heating systems with a boiler of more than 20 kW. As an alternative, Member States may opt for measures that ensure the provision of advice to users concerning the replacement of boilers, other modifications to the heating system and alternative solutions to assess the efficiency and appropriate size of the boiler, provided that these alternative measures have an impact equivalent to regular inspection.

This report from the German Federal Ministry of Transport, Building and Urban Development examines two scenarios for the relevant observation period 2013-2015:

- a reference scenario in which the expected effects of an hypothetical heating system inspection scheme are assessed,

- another scenario with alternative measures.

The report shows that the alternative measures would lead to energy savings clearly higher than those of the reference scenario, both in terms of primary energy needs and CO2 emissions.

In particular, measurements as required by the German regulation BlmSchV result in primary energy savings exceeding those of the reference scenario, even when taking into account the expected uncertainties of the assumptions made.
