IEA Energy in Buildings and Communities (EBC) research projects are examining building energy codes, exploring data utilization for improving energy efficiency, and investigating air cleaning technologies. The aim of this webinar was to share the outcomes of ongoing EBC research projects in these areas and to provide updates on some of the innovative work taking place within the programme: building energy codes and regulations differ between countries and EBC is facilitating dialogue about them with a view to future improvements; high quality energy reporting for buildings at scale allows robust analysis to be carried out and reliable lessons to be learned from the data gathered; advanced analysis of energy data gathered through smart systems is helping to improve building control and performance; technologies to supplement ventilation with gas-phase air cleaning are being studied to confirm if both indoor air quality and energy criteria can be achieved is the focus of further EBC research. Although it has not been possible to arrange the planned EBC Technical Day in Japan due to the ongoing pandemic, their national research priorities and some short overviews of their work within the EBC programme were provided during the webinar. This is being arranged for the benefit of the scientific and engineering research community, as well as for policy and decision makers in industry and governments.
