Buildings account for around 40% of total energy consumption; also buildings account 36%
of CO2 emissions in Europe.
The reduction of energy consumption and the use of energy from renewable sources in the
buildings sector constitute important measures which are needed to reduce energy
dependency and greenhouse gas emissions.
The Directive on Energy Performance in Buildings (EPBD) is the main legislative instrument
affecting energy use and efficiency in the Europe building sector.
The EPBD (Energy Performance in Buildings Directive) will help reduce EU buildings
energy consumption in the long run. A requirement that all new buildings must be net zero
energy consumers by 2020 has received the most attention. The recast further sets a
framework for:
· Creating an integrated methodology for measuring energy performance;
· Establishing minimum performance standards for new and certain existing
buildings; and,
· Conducting regular inspections of critical buildings system.
Proper thermal rehabilitation of a building will lead to a significant reduction of heating
energy demand offering a higher degree of comfort, and better condition for hygiene.
Directive that can be related more directly with the sustainable renovation and sustainable
construction is the European directive about energy performance in buildings.
The main directive of energy performance certificate includes a methodology for calculating
the energy performance of buildings, minimum requirements to achieve cost optimal levels,
the objective of nearly zero-energy buildings by 2020, a point of financial incentives and
market barriers and different points of energy performance certificates.
Last part of this document is about protection of heritage, it is important because the thermal
rehabilitation of housing buildings appears as a great challenge for sustainable urban
development. |
