IEA EBC Annex 68: Indoor Air Quality Design and Control in Low Energy Residential Buildings

In this project, the scientific basis and data for a coupled calculation and evaluation of indoor air quality and energy efficiency of residential buildings were developed. Assessment metrics and detailed air pollutant models were developed and integrated into the building simulation to derive guidance for the planning and operation of energy-efficient residential buildings.

IEA ECBCS Annex 49: Low Exergy Systems for High-Performance Buildings and Communities

The objective of Annex 49 is the development of approaches for reducing the exergy demand of buildings, so as to reduce the CO2 emissions of the building stock and support structures for sustainable and reliable energy systems in the building sector. To achieve the objectives of Annex 49, the following activities have been carried out:Application of exergy analysis and providing tools, guidelines, best-practice examples and background information for planners and decision makers in the fields of construction, energy and politics Support of cost-efficient low-energy/exergy measures for renovation and new building taking into account both the residential and the service sector Promotion of exergy-related performance analysis of buildings, particularly from the perspectives of communities / regions

IEA ECBCS Annex 50: Prefab Systems for Low Energy/High Comfort Building Renewal

Development of integrated concepts for multi-storey buildings, which enable renovations of buildings with high energy efficiency at good user acceptance during the realisation phase as well as afterwards (comfort, affordability). Relevant components: integrated solutions of roof and façade with high rate of pre-fabrication, the possibility of integrating the energy façade/roofs and energy distribution and supply.
