LoginThe current trend in most Western countries regarding building ventilation is to follow the “build tight, ventilate right” strategy.

TN 73: Overview of the trends in building and ductwork airtightness in 16 countries | 2024 | English | 38 pp
TN 72: Ventilation Requirements and Rationale behind. Standards and Regulations of dwellings, office rooms and classrooms | 2023 | English | 56 pp
Many differences exist between countries in the requirements and regulations for ventilation of dwellings, offices, classrooms and other spaces.
TN 70: 40 years to build tight and ventilate right: From infiltration to smart ventilation | 2022 | English | 95 pp
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:
Much progress has been made to improve the airtightness level of new buildings. Still, little is known about the durability of building airtightness, or the impact of degradation on airtightness.
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:
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.
TN 67: Building airtightness: a critical review of testing, reporting and quality schemes in 10 countries | 2012 | English | 40 pp
This report gives a critical review of steps taken in 10 countries (Belgium, Denmark, Finland, France, Germany, Netherlands, Japan, Sweden, UK, USA) with regard to testing and reporting schemes as well as overall quality approaches to improve buil
TN 66: Building air leakage databases in energy conservation policies: analysis of selected initiatives in 4 European countries and the USA | 2012 | English | 24 pp
We collected information on existing envelope air leakage databases from countries that are involved in the AIVC-TightVent project “Development and applications of building air leakage databases”.
Energy use for fan operation can be significantly reduced by a 3-flanked approach:
Due to the rapid urbanization and modernization of Korea, the demand for housing has increased considerably more than in other countries.
The Czech Republic is a landlocked country located in the centre of Europe. The area of the Czech Republic is 78,866 km² and its population is about 10.4 million people.
Low income households in developed and less developed countries suffer from serious indoor environmental problems like heat stress, lack of comfort and poor indoor air quality.
Because of specific urban characteristics, the potential of natural ventilation can be seriously decreased in the urban environment because of reduced wind speeds, high ambient temperatures and increased external pollutant and noise levels.
TN 60: Efficacy of Intermittent Ventilation for Providing Acceptable Indoor Air Quality | 2006 | English | 27 pp
Ventilation standards and guidelines typically treat ventilation as a constant and specify its value.
TN 59: Parameters for the design of demand controlled hybrid ventilation systems for residential buildings | 2005 | English | 120 pp
This AIVC Technical Note has been produced in the frame of the EU RESHYVENT project, conducted from January 2002 to December 2004. An outline of this project is given in the introduction of this report.
The basic strategy for providing indoor air quality in residences is to dilute indoor sources with outdoor air.
Ventilation is required to provide to remove or dilute pollutants and incidentally meets metabolic oxygen requirements for occupants.
TN 56: A review of international literature related to ductwork for ventilation systems | 2002 | English | 62 pp
Ductwork is used for transport of air used for ventilation or air conditioning in buildings. The supply air is typically conditioned (filtered, warmed or cooled, sometimes humidified or dehumidified).
TN 55: A Review of International Ventilation, Airtightness, Thermal Insulation and Indoor Air Quality Criteria | 2001 | English | 203 pp
This review attempts to summarise available airtightness, minimum ventilation rate and indoor air quality requirements, standards, codes of practice and regulations.
TN 54: Residential Passive Ventilation Systems: Evaluation and Design - A Critical Evaluation of the Potential for Adapting European Systems for use in North America and Development of a General Design Method | 2001 | English | 158 pp
Infiltration has long served the residential ventilation needs in North America.
