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.

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".

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.

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.

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).

In the research project 3for2 Beyond Efficiency, low-exergy distributed cooling and ventilation systems for application in the tropics are designed and tested in a demonstrator building in Singapore. The HVAC system designed consists of passive chilled beams for sensible cooling, fan coil units for latent cooling and dedicated outdoor air handling systems for IAQ control. The design reduces building space requirements due to less ventilation equipment.

In 2017, the Air Infiltration and Ventilation Centre (AIVC) identified smart ventilation for buildings as a new and important topic to be addressed. One of the tasks was to agree on a definition of smart ventilation, which was published in March 2018. The purpose of this presentation is to explain and illustrate the smart ventilation definition by AIVC.

Controlling indoor humidity is important in homes, because high indoor humidity is associated with occupant health and building durability issues. Ventilation is often used to avoid peaks of moisture in homes, such as in kitchens and bathrooms. However, in hot-humid climates, outdoor air can have higher humidity than indoors, and continuous whole house ventilation can lead to increases in indoor humidity levels.
