LoginConventional techniques for the measurement of adventitious leakage of building envelopes are based on steady pressurisation at high pressures (e.g. 50 Pa) that are not normally encountered with natural or mechanical ventilation.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
At the start of the measurements, the airtightness of the box was determined, achieving an n50 value of 0.79.
Apartment ventilation to E DIN 1946-6 - A new programme tool for effective planning | 2008 | English
In all areas, concern is growing on the rising numbers of mould occurrences in residential buildings.
This paper will present current procedures on the main amendments in the forthcoming Energieeinsparverordnung (German energy-saving ordinance) for 2009, as they stood at the publication deadline of 30 April 2008, along with the main changes to cer
Thermography is often used to locate leaks in connection with an airtightness check.
This paper starts with a short explanation of how sick buildings and mould were, brought to the focus of the general public in 1993. The media have played a major role in publicizing problems with dampand run-down buildings.
A thermally conductive building envelope must be constructed to be permanently airtight - this has been compulsory according to German building regulations since 1 Jan. 1995. That 6 Para.
According to the recent conclusions of the 'Grenelle de l’Environnement', the energy performance of buildings has become very recently a major concern in France.
The Blower Door procedure has shown itself to be a very effective instrument for analysing and quantifying the various components of the total problem for complex ventilation issues.
Every building must be airtight, and this airtightness is guaranteed by the building envelope.The necessary air change does not happen through the building envelope but through specific measures such as an air intake and extraction plant with heat
Mould during the construction phase must be recognised by all those involved in the project as a defect that can usually, but not always, be avoided.Mould will grow on most building materials and products with organic components if conditions allo
Implementing the EU-directive 2002/91/EF in Danish legislation led to regulations in the Danish Building Regulations on air tightness in buildings set out by the Danish Enterprise and Construction Authority, a department of the Danish Ministry of
Good envelope airtightness is a prerequisite for energy efficiency and effective ventilation of buildings.
For preselected totals of dwelling houses this article describes how statisticalprocedures on basis of small samples can be transferred into the prognosis whether the tolerable upper limit of airtighness is fulfilled or not.
The importance of an airtight building envelope will, with growing awareness of energy efficiency in all European countries, continue to increase. Experience with testing small detached or two-unit houses is available in most countries.
This technical monograph is one of a set produced as part of the ‘REVIVAL’ project – an EU Energie Programme supported demonstration project of energy efficient and sustainable refurbishment of non-domestic buildings in Europe.

The Mechanical supply only (MSO) ventilationsystem has many advantages, such as good airdistribution, easy pre-heating of cold fresh airsupply and prevention of chemical aerosolsintake through wall cavity.
This paper deals with pressurization usingHVAC systems on each floor as acountermeasure against stack effect generated inthe winter in high-rise office buildings that donot use revolving doors at the entrance.
