Due to the EPBD (2010/31/EU) and the related Dutch regulation there's a strong focus on energy savings and efficiency in buildings for many years now. At the same time awareness is growing on all levels that building energy efficiency should not result in a reduction in (thermal) comfort and indoor air quality. Ventilation systems in buildings play an important role in obtaining good IAQ. Indeed, good functioning ventilation systems should be normative in relation to upcoming NZEB.Recent in situ research (AIVC conferences 2014/2015) shows that Dutch legislation and related ventilation standards and guidelines are not futureproof when it comes to achieving the desired IAQ in residential areas in homes.The Dutch National Standards Body (NEN) is currently working together with the market on a completely new generic standard (NEN 1087) for determining the ventilation capacity in buildings. This standard will be connected to the new Building Decree, which is under construction in the Netherlands and turns into effect for all buildings in 2018 at latest.The Dutch government is also working on a new legislative system which is focusing on guaranteed building quality at the end of a building project. This will result in an "as built dossier" which proves the actual build quality (including the building services and energy performance) to the client.So in future, technical knowledge and skills alone, will not be sufficient. It is expected that qualification and certification schemes will become much more important. It offers the ability to demonstrate actual build quality, also with regard to the buildings services like ventilation systems.
