This Directive lays down requirements regarding:
(a) the general framework for a methodology of calculation of the integrated
energy performance of buildings
(b) the application of minimum requirements on the energy performance of new
buildings
(c) the application of minimum requirements on the energy performance of large
existing buildings (> 1000 m
2
) that are subject to major renovation
(d) Energy certification of buildings
(e) regular inspection of boilers and of air conditioning systems in buildings and
in addition an assessment of the heating installation in which the boilers are
more than 15 years old (Article 1 of EPBD)
Consequences of the EPBD
To meet the requirement for "methods to calculate the integrated overall energy efficiency of
buildings" arising from the EPBD, the European Community tasked the CEN (Comité Européen de
Normalisation – European committee for standardization) to draft European Directives on the overall
energy efficiency of buildings.
The TCs (Technical Committee) at CEN developed various calculations and integrated them into an
impressive number of European standards (EN). The general relationships are described in the
document prCEN / TR 15615 ("Declaration on the general relationship among various European
standards and the EPBD – Umbrella document").This means that the impact of windows, building
shell, technical building systems, and building automation functions can now be calculated.
The energy performance of a building is the amount of energy estimated or actually consumed to
meet the different needs associated with a standardized use of the building, which may include:
· Heating EN 15316-1 and EN 15316-4
· Cooling EN 15243
· Domestic hot water EN 15316-3
· Ventilation EN 15241
· Lighting EN 15193
· Auxiliary energy
Initiative of the building automation industry
With regard to article 3 "Adoption of a methodology" the EPBD does not require any explicit
methodology for building automation (refer to the Annex of the EPBD). For this reason, the building
automation industry – with the specific support of Siemens experts applied to the appropriate EU and
CEN committees to have building automation functions included in the calculation methodologies. In
response, a standard for calculating the impact of building automation functions was drawn up by the
CEN / TC247 (standardization of building automation and building management in residential and
non-residential buildings) to supplement the standards for the building shell and the individual
disciplines:
