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.

While building airtightness is a key concern in Nearly Zero-Energy Buildings in most European climates, there exists already a wide range of commercially-available products specifically designed to minimise leakage in building envelopes. The objective of this webinar was to give information on the performance and properties of these products based on research including laboratory and field tests. The speakers also provided information on standards already published and under development on this subject.

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.
