There exist several initiatives in different parts of the world to bring a stronger basis to ventilation requirements in relation to indoor air quality and health issues, for example, at LBNL in the US...

While it is generally accepted that ventilation-whether natural, mechanical or hybrid- is needed to provide acceptable indoor air quality and prevent building damage, there are debates about...

With the trend towards low-energy buildings, the importance and the interest for building air tightness is increasing. This implies an increasing number of tests, calling for increased attention to the quality of those tests including...

The COVID-19 pandemic has an unprecedented impact on all of us, both personally and professionally. As researchers and practitioners we also have a role to play in developing solutions to provide healthy indoor spaces...

The trend to increasingly complex ventilation controls (particularly for residences) is leading to many new possibilities related to IAQ and energy optimization. This project is needed to ensure that ventilation systems claiming to be...

The current development in building energy efficiency towards nearly-zero energy buildings represents a number of new challenges to building design and construction. One of the major challenges is the increased need for cooling...

An increasing number of countries (e.g. Czech Republic, Denmark, France, Germany, Ireland, Netherlands, Norway, Portugal, UK) include in their regulations either required or recommended minimum airtightness levels with or without mandatory testing...

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. This raises increasing concerns...
