Indoor Environmental Quality

Improving or ensuring an acceptable indoor environmental quality (thermal, visual, acoustical comfort and indoor air quality) and preserving occupants’ health and well-being while taking measures to reduce buildings’ energy use is a key driver in both new and existing buildings.

AIVC is working on IAQ metrics and is actively involved in the Indoor Environmental Quality Global Alliance (IEQ-GA)- https://ieq-ga.net/, of which it is one of the founding members.

Building & Ductwork airtightness

Building airtightness requires a continued attention both in existing and new buildings. Good building airtightness contributes to energy use reduction in most climates and, in combination with ventilation systems, better control of IAQ.  The expression already from the 1980s, i.e.

Newsletters

Since 2011, the AIVC publishes twice a year a 4-page newsletter. In between 2 issues of the AIVC newsletter the venticool and TightVent are published. In practice, you receive a newsletter on average bi monthly  dealing with ventilation, airtightness and ventilative cooling. These newsletters aim to keep you informed on the progress of the various projects as well as to learn about initiatives (publications, events, etc.) of interest.

Indoor Air Quality-IAQ metrics

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...

Rationale behind ventilation requirements and regulations

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...

40 Years of AIVC

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...

Utilization of heat recovery in residential ventilation systems

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...

Cooker hoods in residential buildings

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...

Quality of methods for measuring ventilation and infiltration in buildings

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...
