Progressing the scientific basis of indoor environmental quality is essential to understand which aspects can be better optimised to substantially reduce energy use in buildings. In recent years, IEA Energy in Buildings and Communities (EBC) international research projects have been investigating for this purpose both indoor air quality and thermal comfort. The embodied impacts of buildings and their services systems are also a focus of EBC's research.

The current development in building energy efficiency towards nZEB buildings represents a number of new challenges to design and construction. One of these major challenges is the increased need for cooling in these highly insulated and airtight buildings, which is not only present in the summer period but also in the shoulder seasons and in offices even in midwinter. Resilient ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.
We are now pleased to announce the release of our Ventilation Information Paper no 41: Impact of wind on the airtightness test results. This paper aims to present and discuss the calculation method of standard ISO 9972 regarding the uncertainty induced by wind; gather published knowledge and determining what further research is needed on the quantification of the wind impact on airtightness tests results (including numerical simulations, laboratory and on-site measurements studies) and; give guidance for minimizing and better estimating the wind impact on airtightn

Building airtightness tests have become very common in several countries, either to comply with minimum requirements of regulations or programmes, or to justify input values in calculation methods. With more widespread use it has become increasingly important to understand and quantify the reliability of these tests.
The World Health Organization (WHO) developed and published a roadmap on how to improve ventilation in indoor spaces in the context of COVID-19. The roadmap is divided into three settings – health care, non-residential and residential spaces – and takes into account different ventilation systems (mechanical or natural). The roadmap is aimed at health care facility managers, building managers, as well as those members of the general public who are providing home care or home quarantine.
The Air Infiltration and Ventilation Centre and the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (https://annex86.iea-ebc.org/) are organizing the webinar Big data, IAQ and ventilation – part 1 to be held on April 13th, 2021 at 17:00-18:30 CET. The webinar will address the applications of IoT devices and big data in IAQ and ventilation and discuss the possibilities they provide for research.
