a first step on the timetable to reinforce energy performance requirements for nonresidential
buildings;
a cost-optimal study;
an obligation for experts to upload their energy performance certificates of residential
buildings into a database;
a modification of the supporting financial scheme concerning residential buildings.
Luxembourg is gradually increasing the energy performance requirements of residential
buildings (primary energy needs of the building) and the thermal insulation requirements
(heating energy demand of the building). As of 1 January 2017, the A-A standard, which has also
been defined, in principle, as the NZEB standard, will become mandatory. NZEBs will be highly
energy-efficient buildings. For non-residential buildings, the energy performance requirements
were reinforced as of 1 July 2015, increasing from the D-D (primary energy needs and heating
energy demand) level required since 2011, to C-C level. The NZEB for non-residential buildings
is expected to become mandatory from 1 January 2019 (the exact timeline and definition are
still to be determined).
The first figure below shows the timeline of strengthening energy performance requirements
for new residential buildings and the second one, the reduction of energy needs over time.
Building renovation
With regard to Article 4 of the Energy Efficiency Directive (EED), Luxembourg is still working on
the final establishment of the national long-term strategy for mobilizing investment in the
renovation of the national stock of residential and non-residential buildings, both public and
private. In the Third National Energy Efficiency plan for Luxembourg, the development of the
energy efficiency of buildings in the case of renovation has already been reported.
