IEA EBC Annex 64: Optimised Performance of Energy Supply Systems with Exergy Principles (Working period 2014-2018)
To reduce CO2 emissions in cities, an overall understanding of energy conversion processes is necessary, which also takes temperature levels into account. This is particularly important when alternative heat sources such as waste heat, ambient heat, solar and geothermal energy are to be used, as these often have a low temperature level, i.e. a low exergy content. Accordingly, urban energy systems are analysed and optimised within the framework of the IEA EBC Annex 64 with the help of the exergy approach.
