The Proceedings of the 32nd AIVC Conference " Towards Optimal Airtightness Performance", held in Brussels, Belgium, 12-13 October 2011.
This paper presents some first approaches for the national application of the nearly zero-energy building definition according to the Energy…
It is widely accepted that ventilation is critical for providing good indoor air quality (IAQ) in homes. However, the definition of "good" IAQ, and the most…
The EPBD (EU Energy Performance of Buildings Directive) Concerted Action is a cooperative effort from all 27 EU Member States (MS), plus Norway and Croatia…
Today an acceptable indoor air quality is mainly defined by specifying the required level of ventilation in air changes per hour or the outside air supply…
A retrofit study was conducted in an unoccupied manufactured house to investigate the impacts of airtightening on ventilation rates and energy consumption.…
The airtightness of inclined roofs is important in order to avoid hygrothermal problems and to guarantee the durability of the construction itself. Previous…
Recently, insulation retrofits of existing houses have been thought to be one of the effective measures from the viewpoint of global warming prevention…
Starting January 1st, 2013 the French thermal regulation will impose a minimum requirement for residential buildings air-tightness. However, nothing is…
Recently, the requirements regarding global building airtightness to reduce the exfiltration losses became more severe as result of the trend towards very…
This study documented that houses in the southeastern United States built on typical wall-vented crawl spaces possess the following characteristics: 1) bulk…
Accidental releases occurring in industrial platforms or during transportation of hazardous materials can entail the dispersion of toxic gas clouds. In…
It has been demonstrated that there is a strong relationship between occupant behaviour and the thermal performance of dwellings. At the same time,…
In a great portion of Danish primary schools the mechanical ventilation systems is outdated or simply rely on opening of windows to ventilate the classrooms…
The aim of this study is to check the accuracy of a nodal model to predict correctly the flow fields involved inside a building by wind-induced pressure.…
From the beginning of year 2007 the buildings in Finland must have energy efficiency calculations, which requirements are now part of Building Codes, based…
There are often practical limitations to measure the airtightness of a multifamily building as a whole as described in EN 13829. The building may be…
A building was tested the equivalent of over 1,000,000 times under windy conditions where each test satisfied the conditions of ASTM, CGSB, ISO, EN, ATTMA…
The air tightness of building has been a serious problem over the last 30 years. In 1979 the international Air Infiltration Centre (AIC) was erected within…
In this study, we developed an integrated simulation procedure for prediction of concentration of contaminant exposure using a multi-nesting method…
