Standard EN 13779:2007 has been withdrawn (01/02/2018) and in its place the following should be used:
To replace EN 13779:2007 Annex A2 for location of the building’s air intakes and exhausts – CEN/TR 16798-4:2017
To replace EN 13779:2007 Annex A3 for filtration in HVAC systems – EN 16798-3:2017
To replace EN 13779:2007 for providing fresh air into the building – ISO 17772-1:2017 (using design values of Category I buildings in Annex I)
Existing projects can continue to use EN 13779:2007 where applicable. Any new assessment registrations should use the replacements above.
