OBJECTIVES
The main objective of Annex 49 is to develop concepts for reducing the exergy demand in the built environment, thus reducing CO2 emissions from the building stock and supporting structures for setting up sustainable and secure energy systems for this sector.

Specific objectives are:
- to use exergy analysis to develop tools, guidelines,recommendations, best-practice examples and background material for designers and decision makers in the fields of building, energy production and politics
- to promote possible energy/exergy cost-efficient measures for retrofit and new buildings, such as dwellings and commercial/public buildings
- to promote the exergy-related performance analysis of the buildings, from the community level perspective
