TN 70: 40 years to build tight and ventilate right: From infiltration to smart ventilation

As the AIVC was created in 1979, the 40th anniversary of the AIVC was celebrated in October 2019 at the 40th AIVC conference in Ghent. In the context of this celebration, it was decided to publish 2 overview publications:

VIP 39: A review of performance-based approaches to residential smart ventilation

Ventilation Information Paper no39: “A review of performance-based approaches to residential smart ventilation” provides an overview of the regulations and standards proposing “performance-based approaches” in five countries to promote the use of smart ventilation strategies. It shows that a favorable context exists in many countries for the development of smart ventilation strategies.

VIP 38: What is smart ventilation?

In March 2017, AIVC identified smart ventilation for buildings as a new and important topic to be addressed.

Several actions were defined by AIVC Board about this topic in order to exchange and disseminate information on this topic. A working group of AIVC experts from several countries was created. One of its tasks was to agree on a definition of smart ventilation.

The purpose of this ventilation information paper is to present and illustrate this definition of "smart ventilation".

AIVC's Technical Note 70: 40 years to build tight and ventilate right: From infiltration to smart ventilation

We are happy to announce the release of AIVC's Technical note #70: 40 years to build tight and ventilate right: From infiltration to smart ventilation!

As the AIVC was created in 1979, the 40th anniversary of the AIVC was celebrated in October 2019 at the 40th AIVC conference in Ghent. In the context of this celebration, it was decided to publish 2 overview publications:

Big humidity data from smart ventilation systems

A smart ventilation system is generally equipped with a range of sensors. The data – or data derived from it - collected by these sensors can be used by both building owners, occupants and managers. A new generation of IoT  enabled residential ventilation systems allows collecting and analysing this data at scale to get a better view on typical IAQ conditions in dwellings. In this paper, the results from such an analysis on the first 900 installed devices of a new model with respect to moisture in relatively new Belgian dwellings is presented.

Indoor air quality investigation in a ventilated demonstrator building via a smart sensor

This study deals with ventilation effects on measured and perceived indoor air quality (IAQ) in a demonstrator building where IAQ problems can occur. Unlike outdoor air, indoor air is usually recycled continuously, which makes it trapping pollutants. Indoor air quality (IAQ) is characterized by a pollutants' concentration, as well as air temperature and humidity. The study's aim is to implement an efficient and smart ventilation system while leaning on continuous measurements of indoor air pollutants in a demonstrator building via a smart sensor based on a Raspberry Pi 3 model B+ card.

Economics of Indoor Air Quality

Buildings represent a major end use of energy throughout the world and are typically the dominant sector for electricity.   The use of that energy is to provide buildings services, the most important of which is Indoor Environmental Quality (IEQ).  Heating and air conditioning systems typically handle the thermal comfort aspects of IEQ; the energy impacts and economics of such systems is well studied.  The most important remaining aspect of IEQ is Indoor Air Quality (IAQ).
