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".

TN 68: Residential Ventilation and Health

Exposures in homes constitute the major part of exposures to airborne pollutants experienced through the human lifetime. They can constitute from 60 to 95% of our total lifetime exposures, of which 30% occurs when we sleep.

VIP 42: The Concept for Substituting Ventilation by Gas Phase Air Cleaning

Worldwide, there is an increasing number of publications related to air cleaning and sales of gas phase air cleaning products. This puts a demand for verifying the influence of using air cleaning on indoor air quality, comfort, well-being and health. It is thus important to learn whether air cleaning can supplement ventilation with respect to improving air quality i.e. whether it can partly substitute the ventilation rates required by standards.

VIP 41: Impact of wind on the airtightness test results

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. With more widespread use it has become increasingly important to understand and quantify the reliability of these tests.

Airtight Buildings, Thermography and Ventilation Systems in Practice

The book of proceedings of the 11th International BUILDAIR Symposium "Airtight Buildings, Thermography and Ventilations Systems in Practice",  held on May 24- 25  2019, in Hannover, Germany. Contains 25 abstracts.

Airflows and moisture sources in lightweight wall structures

Purpose of the work

Quantification and location of moisture penetration through leak-dependent creeping flows from the room into insulated, lightweight wall structures as a function of design, pressure differential, and leak position.

Method of approach

Pressure-dependent, high-precision through-flow measurement in a facade test stand and determination of the amount and distribution of condensate in a double climate chamber performed on lightweight wall sections with different cavity wall insulation and leak positioning.
