ANNEX 49

Annex 49 aims at improving, both on a community and building level, the design of energy use strategies which account for the different qualities of energy sources, from generation and distribution to consumption within in the built environment. Annex 49 is based on an integral approach which includes the analysis and optimization of the exergy demand in the heating and cooling systems as well as in other processes where energy/exergy is used within the building stock... The Fraunhofer Institute for Building Physics IBP was founded in 1929 and is among the most experienced and established institutes of the Fraunhofer-Gesellschaft. A total of 264 employees work at the three branches in Stuttgart, and Holzkirchen. It has an annual budget of over 27,8 million euros, with approximately one third coming from industrial projects... The low-exergy approach aims at satisfying the remaining thermal energy demand using only low quality energy.
