Worldwide, there is an increasing number of publications related to air cleaning and there is an increasing sale of gas phase air cleaning products. This puts a demand for verifying the influence of using air cleaning on indoor air quality, comfort, well-being and health. It is thus important to learn whether air cleaning can supplement ventilation with respect to improving air quality i.e. whether it can partly substitute the ventilation rates required by standards. There is also a need to evaluate the energy impact of using air cleaning as supplement to ventilation.

The transition to climate neutrality has a large impact on the job of building and HVAC designers, manufacturers, installers, investors, etc. Renovating our building stock to make it more energy efficient is a huge task. Both research and practice prove that users have an important impact on this performance. Human-building interactions, like window opening, thermostat and solar shading usage, affect the performance of the building and HVAC systems.

Well-insulated and air-tight buildings are known to be vulnerable to overheating. An increase in the severity and duration of heatwaves is expected, resulting in more severe overheating risks, affecting in turn the health and mortality of building users. To achieve more future-proof buildings, it is crucial to design buildings that are “resilient” to overheating in future climate conditions.

IEA Energy in Buildings and Communities (EBC) research projects are helping to substantially reduce energy demands in buildings and fully exploit renewable energy sources. With a focus on Germany, this webinar will explore energy policy for buildings and how national and international innovation activities are contributing to this.

In the context of energy use reduction, low energy buildings are becoming more widespread. This kind of construction requires a good envelope airtightness to prevent uncontrolled leakages of conditioned air leading to energy losses. As a result, more and more ventilation systems are installed to ensure a sufficient air change rate, to guarantee good indoor air quality and building durability while controlling energy losses.

Building airtightness tests have become very common in many countries, either to comply with minimum requirements of regulations or programmes, or to justify input values in calculation methods. Thus, it has become very important to understand and quantify the reliability of these tests. According to the present ISO 9972 standard, the zero-flow pressure shall not exceed 5 Pa for the test to be valid. On one hand, in moderately windy conditions it may be impossible to perform a pressurisation test in accordance with the standard, even if an uncertainty analysis would show small test errors.

This webinar, organized by the Air Infiltration and Ventilation Centre & the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (https://annex86.iea-ebc.org/), addressed the opportunities to use novel materials (from advanced functional nano-materials to bio-based building materials) as building components to actively/passively manage the IAQ, for example, through active paint, wallboards, and textiles coated with advanced sorbents or catalysts and quantify their potential, based on the as
