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)-, 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.

Metal Oxide Semiconductor sensors to measure Volatile Organic Compounds for ventilation control

The application of Metal Oxide Semiconductor (MOS) sensors measuring Volatile Organic Compounds (VOC) gains increasing attention in the ventilation community because of their low price and claimed ability to supplement or even substitute CO2 sensors for demand controlled ventilation (DCV). Even though there are many “Indoor Environmental Quality” meters available on the market, in which these sensors are used, the amount of scientific studies focused on their reliability and applicability is still limited.
