32nd AIVC and 1st TightVent Conference - Brussels, Belgium - 12-13 October 2011
The 32nd AIVC and 1st TightVent Conference - Towards Optimal Airtightness Performance, was held in Brussels, Belgium, 12-13 October 2011.
Contains 60 papers.
This paper presents some first approaches for the national application of the nearly zero-energy building definition according to the Energy Performance of Buildings Directive by summarising the current plans of Germany, Denmark, Ireland and the N
It is widely accepted that ventilation is critical for providing good indoor air quality (IAQ) in homes.
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, together with the European Commission.
Can we meet the ventilation required in international standards in an energy efficient way? | 2011 | English
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 rate.
Impacts of airtightening retrofits of ventilation and energy in a manufactured home | 2011 | English
A retrofit study was conducted in an unoccupied manufactured house to investigate the impacts of airtightening on ventilation rates and energy consumption.
The influence of air permeability and type of underlay on the hygrothermal performance of an inclined roof | 2011 | English
The airtightness of inclined roofs is important in order to avoid hygrothermal problems and to guarantee the durability of the construction itself.
Investigations on the effects of airtight performance improvement and energy consumption of insulation retrofit in detached houses | 2011 | English
Recently, insulation retrofits of existing houses have been thought to be one of the effective measures from the viewpoint of global warming prevention.
State of the Art of Non-Residential Buildings Air-tightness and Impact on the Energy Consumption | 2011 | English
Starting January 1st, 2013 the French thermal regulation will impose a minimum requirement for residential buildings air-tightness. However, nothing is planed for non-residential building, for two reasons:
Laboratory investigation of timber frame walls with an exterior air barrier in a temperate climate | 2011 | English
Recently, the requirements regarding global building airtightness to reduce the exfiltration losses became more severe as result of the trend towards very low energy buildings and Passive Houses.
Liabilities of vented crawl spaces and their impacts on indoor air quality in southeastern U.S. homes | 2011 | English
This study documented that houses in the southeastern United States built on typical wall-vented crawl spaces possess the following characteristics: 1) bulk water, water vapor and associated moisture issues, 2) mold spores, 3) measured holes betwe
Shelter in place strategy: CONFINE, an airtightness level calculation tool to protect people against accidental toxic releases | 2011 | English
Accidental releases occurring in industrial platforms or during transportation of hazardous materials can entail the dispersion of toxic gas clouds.
Definition of occupant behaviour patterns with respect to ventilation by means of multivariate statistical techniques | 2011 | English
It has been demonstrated that there is a strong relationship between occupant behaviour and the thermal performance of dwellings.
Performance of low pressure mechanical ventilation concept with diffuse ceiling inlet for renovation of school classrooms | 2011 | English
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 on European Performance of Buildings Directive.
Evaluation of selection criteria of an air tightness measurement method for multifamily buildings | 2011 | English
There are often practical limitations to measure the airtightness of a multifamily building as a whole as described in EN 13829.
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 and USACE testing standards in every respect.
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 the International Energy Agency (IEA) platform.
Exposure Concentration Prediction by Multi-Nesting Approach Connecting Building Space-Virtual Manikin- Nasal Airway Model | 2011 | English
In this study, we developed an integrated simulation procedure for prediction of concentration of contaminant exposure using a multi-nesting method connecting building space, a Virtual Manikin, and bronchus airway in humans.
