IEA ECBCS ANNEX 49
Annex 49 is a task-shared international research project initiated within the framework of the International Energy Agency (IEA) programme on Energy Conservation in Buildings and Community Systems (ECBCS). ECBCS Annex 49 is a three year project. 22 research institutes, universities and private companies from 12 countries are involved. The main objective of this project is to develop concepts for reducing the exergy demand in the built environment, thus reducing the CO2-emissions of the building stock and supporting structures for setting up sustainable and secure energy systems for this sector. Annex 49 is based on an integral approach which includes not only the analysis and optimisation of the exergy demand in the heating and cooling systems but also all other processes where energy/exergy is used within the building stock. In order to reach this aim, the project works with the underlying basics, i.e. the exergy analysis methodologies. These work items are aimed at development, assessment and analysis methodologies, including a tool development for the design and performance analysis of the regarded systems. With this basis, the work on exergy efficient community supply systems focuses on the development of exergy distribution, generation an storage system concepts.
