Extensive research studies in many countries have found gaps between the design intent and real-world operation of buildings, which often lead to much higher energy use in practice than was estimated at design stage. While the reasons for such performance gaps are varied and complex, IEA Energy in Buildings and Communities (EBC) research projects have recently been making progress in resolving them. The aim of this webinar is to share the outcomes of ongoing EBC research projects in this area and to provide updates on some of the innovative work taking place within the programme: 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; data collected for individual buildings using smart meters are helping to understand fabric thermal performance at previously unattainable sample sizes; 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; occupant-centric building design and operation are the focus of further EBC research. Although it has not been possible to arrange the planned EBC Technical Day in the Netherlands due to the ongoing pandemic, their national research priorities and some short overviews of their work within the EBC programme will also be 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.
