  AIVC Workshop: Towards higher-performing buildings

AIVC banner.JPG

Objective of the AIVC Workshop 

The objective of this AIVC workshop was to discuss and identify ways to improve the quality of our homes with respect to airtightness and ventilation, as well as discussing the impact suboptimal performance has on energy consumption and health of the occupants. Also of interest are the impacts of mandatory airtightness targets and how best to implement these, if at all.

This has led to the development of our Warmer, Drier Healthier Buildings research programme in consultation with industry and other key stakeholders. This programme looks at solutions to allow buildings to be warm, dry and healthy over their lifetime. It will also provide the information we need to improve comfort, temperature and heating to support better health outcomes.
