Another primary function of a Vapour Barrier would be the assurance of a heated or cooled interior environment resisting impact by the outside opposing temperature (sometimes referred to as a Thermal Envelope). This in turn also directly impacts energy efficiency as the HVAC system does not have to work as hard to maintain a constant indoor ambient temperature. Thermal values remain more constant, and that in turn saves money and energy. This thermal envelope has many factors leading to it, including insulation and the use of a blower door  . These tests are conducted to see a range of results, from the relative efficiency of a basement washroom exhaust fan, all the way to how well a skyscraper holds its air conditioning.
