Health is one of the most powerful reasons for IEQ management, however, the 2 dominant available definitions are not fully fit for purpose. The WHO definition is broad and encompasses all potential IEQ related benefits, but...
AIVC Projects
Since 2011, AIVC activities have been structured around projects, integrating activites and products such as publications, webinars, workshops etc. Click on the related contents below to know more about AIVC’s projects.

Airtightness of exterior walls in buildings has a great impact on indoor environment, energy consumption and overall building performance. However, the measurement of exterior wall airtightness is not easy, especially in...

Epidemic and disaster preparedness of buildings and systems is a key area of concern. The study of how building ventilation and airtightness may contribute to disaster preparedness may lead to better guidelines for...

In 2008 a series of Ventilation Information Papers (VIP 17 to VIP 27) were published detailing the “Trends in the building ventilation market and drivers for changes” for 10 countries. Regulations have however evolved...

Personalised Environmental Control Systems (PECS) with the functions of heating, cooling, ventilation, lighting, and acoustics has advantages of controlling the localized environment at occupant’s workstation by their preference...

The energy recovery ventilators are tested according to ISO 16494 for static plate types (two different configurations of test apparatuses are included), ISO 21773 for rotary types or other relevant international and national testing standards...

The European market for residential ventilation is highly driven by energy performance regulations. In new buildings the share of energy efficient ventilation systems such as demand controlled mechanical exhaust ventilation...

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 international standards for indoor environmental quality (ISO17772-1 and EN16798-1)open up for a possible reduction in required ventilation if gas phase air cleaning is used. This has been followed up by an IEA-EBC Annex 78...

This project deals with reviewing EBC's Annex 5: "Air Infiltration and Ventilation Centre" activities & contributions on the occasion of the project's 40th year of operation. The objective of this project is to disseminate...

There have been many new sensors introduced on the market claiming that they can perform accurate measurements of Indoor Air Quality. Many of them are low-cost sensors that can be applied at the mass scale. The subsequent...

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...

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...

Internationally there are many different requirements and regulations for ventilation. Sometimes the variation is more than a factor of five. There are strong drivers to reduce energy consumption for HVAC, and therefore the spread in...

The European market for residential ventilation is highly driven by energy performance regulations. In new buildings the share of balanced ventilation with heat recovery is increasing as a result of more severe...

The trend towards more nearly zero energy buildings and much more airtight buildings represents specific challenges for cooker hoods in residential buildings. The application of cooker hoods represents various challenges...

There is a trend to perform more ventilation and air infiltration measurements in buildings, either to strengthen commissioning procedures or to learn from field data. This trend is stronger in nearly zero-energy buildings projects or programmes...

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...

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...

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...

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...
