The procedure incorporates the door-fan-pressurization method and is intended to characterize the airtightness
of any building enclosure, or part of that enclosure (i.e., wall, floor, and roof).
The study that is the subject of this lot will have to find the equilibrium of the temperatures and the relative humidity levels necessary for the good preventive conservation of the works, both by the modification of the existing installations and the addition new technical installations and the treatment of the outer casing (thermal insulation and airtightness
) which influences the external contributions and the losses.
Survey studies exist that summarize residential and commercial building airtightness
data (Sherman and Chan 2004; Persily 1998).
In 2007 ASHRAE established a committee, SPC193P, Method of Testing for Determining the Air-Leakage Rate of HVAC Equipment, to develop a test method of AHU cabinet airtightness
in addition, for the special services listed below (annex 1 to section 3 (1) of the hoai, section 1.2.2): lph 8: - participate in the site inspection - proof of energy efficiency (id according to enev), - performing the airtightness
test results were calculated by the data analysis software using CGSB Standard 149.10-M86, Determination of Airtightness
of Building Envelopes by the Fan Depressurisation Method.
(3) Although only limited airtightness
data on commercial buildings exists, these data reveal that commercial building envelopes are generally quite leaky and that there is no trend of increasing airtightness
in newer buildings.
Lot 07: interior joinery, drywall, insulation, airtightness
The objective of this study is to investigate the impact of envelope airtightness
on the energy consumption of typical commercial buildings in the US.

Melanie said: "The houses boast extremely high levels of thermal and acoustic insulation and airtightness
, allowing for savings of up to 50% on fuel bills.
The estimated contribution of radon to lung cancer risk varied widely by country, with the variation influenced by tobacco smoking rates, geology, and home characteristics (for instance, a dwelling's airtightness
or the floor area in contact with the ground), says lead author Janet Gaskin, a PhD candidate in the School of Epidemiology and Public Health at the University of Ottawa.
