LoginEvery 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

At the start of the measurements, the airtightness of the box was determined, achieving an n50 value of 0.79.
Recent efforts of French professionals from the building sector to account for airtightness | 2008 | English
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.
High standards of airtightness for building envelopes protect occupants against common outdoor air pollutants - especially pollen and mildew spores that occur seasonally in high concentrations and can penetrate indoor spaces.
Testing the airtightness of Large or multiple-storey-buildings in an EU-Regulation Context | 2008 | English
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 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.
Good envelope airtightness is a prerequisite for energy efficiency and effective ventilation of 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
Incidence of mould/mildew on building materials - Causes, prevention and rectification with special reference to airtightness and ventilation | 2008 | English
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
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.
Detailed information from Blower Door tests - the basis for differentiated building analysis and optimised renovation - case study: office building | 2008 | English
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.
Conventional 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.
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.
Statistical Airtightness Inspection of Typed Buildings - Basics, Procedure, Examples | 2008 | English
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.
Documenting defects with active thermography when checking airtightness - an interesting alternative | 2008 | English
Thermography is often used to locate leaks in connection with an airtightness check.
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
