AllClimate promotes the Passive House Standard to increase public understanding of highly energy efficient buildings that reduces greenhouse gas emissions and provides resilient structures that can withstand extreme weather related to climate change. Our mission is to make the International Passive House standard of building performance understood, achievable, and adopted through education.
​
The Passive House Standard can be implemented in all climates over the world and the general approach is always the same. Depending on the local climate, the properties of individual components will vary. In hotter climates, for example, special attention should be paid to passive cooling measures, such as shading and window ventilation, to ensure comfort during the hot months. The individual characteristics of any Passive House should be optimised to the local conditions.

AIRTIGHTNESS (BLOWER DOOR) TESTING
​
We perform airtightness (blower door) test compliant to ISO 9972 Thermal Performance of Buildings and CAN-CGSB-149.10 Determination of the airtightness of building envelopes by the fan depressurization method. This test determines the building's air changes per hour at 50 pascals (ACH@50 Pa), which the number of times per hour the entire conditioned (heated or cooled) volume of air in a house is replaced when the building envelope is subjected to an interior-exterior pressure differential of 50 pascals (Pa).

Add-on Services:
​
Air Leakage Location Identification using Infrared Thermal Scanner and/or Smoke - we will walk around the inside of the house and use an air movement indicator (infrared thermal scanner and/or smoke) to locate air leakage points in the house.
Exhaust Device Depressurization Test - performed on houses with combustion spillage susceptible appliances (e.g. combustion equipment that vents through a chimney such as fuel-fired natural draft furnaces, boilers, domestic water heaters, fireplaces and solid fuel-fired appliances). This test determines the level of house depressurization that can occur when all of the home’s exhaust appliances and ventilation devices are operating at the same time. A negative pressure environment could create backdrafting conditions, potentially resulting in the spillage of hazardous combustion exhaust gases into the house.
