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.

IEA EBC Annex 70: Building Energy Epidemiology: Analysis of Real Building Energy Use at Scale

Within the framework of the IEA-EBC Annex 70, causes of deviations between calculated and actual energy consumption in buildings were empirically investigated and requirements for data quality, characteristics and security were developed. Furthermore, recommendations were developed regarding the use of internationally uniform standards and methods for data collection, processing and evaluation.

IEA EBC Annex 71: Building Energy Performance Assessment Based on In-situ Measurements

The requirements on building envelope and on building technology are steadily increasing. There is a lack of monitoring and analysis methods to control the quality of the built implementation. The objective is to provide methods for an on-site (in situ) assessment of the actual energy performance. Based on the results from EBC Annex 58, this Annex takes the step towards practicable characterization procedures.
