In Poland air tightness test is not obligatory, only advisable. In effect buildings are still not air tight enough to reach a milestone of energy saving.
Codes do not require. Various programs may require e.g. for energy label it is required. Blower door technology is described on the internet and used for last 25 -30 years.
Piotr,
The U.S. residential code required enclosure testing beginning in the 2009 IECC. Only a handful of states have fully adopted the 2009/2012 IECC - Georgia and Maryland come to mind. Other states like Virginia have amended out the enclosure testing in favor of visual inspections of enclosure. Energy sode adoption is very political in the U.S. and lacks uniformity in its enforcement.
In Argentina, the regulations do not require providing this test.
Canada does not require an "air-tightness" test. However, buildings will often be tested for "heat loss" (not required either) before mediation and then again after to determine if improvements have really been made.
My country's regulations do not generally require providing an air tightness test, only heat loss, before and after the construction.
In the other hand, last two years we had done an study in historic buildings, according the ISO 9869.
Thank you for interesting answers to my question. I hope to continue this topic.
States regulations do not require such tests in Switzerland, but the state of the art described in the Swiss standard SIA 180 gives upper limits for air permeablity of the building envelope for new and retrofitted buildings. Therefore, tests according to ISO 9869 may be performed when there are complaints to check if these limits are overpassed or not.
In addition, tests are mandatory for getting the Minergie P label. The maximum allowed air change rate @ 50 Pa is then 0.6/h. See http://www.minergie.ch/ (in German, French or Italian)
In Belgium it's required if you do not want to use the default value of air tightness in the EPBD assessment, though mainly only used if the applicant wants to prove it's a very air-tight building close to Passivhaus standard.
In Norway, it is obligatory to do it twice: once in construction phase and once at the end of the project.
In Colombia the regulations do not require providing air tightness test.
Building Regulations require that builders/developers prove the air tightness of a sample of new buildings on any development.
The regulations set a maximum allowable air permeability measure for all buildings but the specific performance required on any given unit will depend on the SAP or SBEM calculations which determine whether the building's Design Emission Rate (DER) is below the Target Emission Rate (TER).
