Promoting healthy and energy efficient buildings in the European Union: National implementation of related requirements of the Energy Performance Buildings Directive (2010/31/EU)

EU Member States have been developing policies and measures to reduce the energy consumption of their buildings with a number of challenges need to be addressed in terms of the impact of high energy performance on indoor climate conditions. The Energy Performance Buildings Directive (2010/31/EU) requires Member States to consider how high-energy performance affects general indoor climate conditions, in order to avoid possible negative effects such as inadequate ventilation, poor indoor air quality etc. This has particular relevance for nearly zero-energy buildings in which improved air tightness and poor ventilation systems may cause potential air quality and consequently health issues. This report reviewed and analysed existing studies, reports and investigations which have been examining the impact of high energy performance on indoor air quality and provides recommendations on how establishing healthy and energy-efficient buildings in the European Union.
