2. Air door - Wikipedia

   en.wikipedia.org/wiki/Air_door

   A typical commercial air curtain enclosure. In North America, the more commonly-used term for an air door is "air curtain". The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines an air door as follows: "In its simplest application, an air curtain is a continuous broad stream of air circulated across a doorway of a conditioned space.

3. Blower door - Wikipedia

   en.wikipedia.org/wiki/Blower_door

   Blower door installation (France) Depending on how a blower door test is performed, a wide variety of airtightness and building airflow metrics can be derived from the gathered data. Some of the most common metrics and their variations are discussed below. The examples below use the SI pressure measurement unit Pascal (pa). Imperial measurement ...

4. Air changes per hour - Wikipedia

   en.wikipedia.org/wiki/Air_changes_per_hour

   The most common technique to measure airtightness is the fan pressurization method, also known as the blower door test. It is measured by the number of air changes per hour (ACH) that occur when there is a differential pressure of 50 pascals between outside and inside the building.

5. Duct leakage testing - Wikipedia

   en.wikipedia.org/wiki/Duct_leakage_testing

   A third test method to determine if ductwork is leaking to the outside is to use a pressure pan, which is a register cover with a pressure tap for a hose connection. With the house pressurized (or depressurized) to 50 Pa (-50 Pa) using a blower door, a pressure gauge is attached to the pressure pan by means of a hose.

6. Harold Orr - Wikipedia

   His research on air leakage in houses led to the development of the blower door, a tool still used today for tightness testing in houses. [2] [3] [4] He also helped to develop the HotCan software, which continues to be used for whole house energy analysis and energy code compliance under the name HOT2000. [5] [6]

7. Building envelope - Wikipedia

   en.wikipedia.org/wiki/Building_envelope

   The physical components of the envelope include the foundation, roof, walls, doors, windows, ceiling, and their related barriers and insulation. The dimensions, performance and compatibility of materials, fabrication process and details, connections and interactions are the main factors that determine the effectiveness and durability of the ...

9. Infiltration (HVAC) - Wikipedia

   en.wikipedia.org/wiki/Infiltration_(HVAC)

   Smoke candles and blower-door tests can help identify less-than-obvious leaks. The Weatherization article describes methods for energy savings further. If infiltration is reduced below 0.35 ACH, it is recommended that mechanical ventilation (typically an exhaust fan or heat recovery ventilation ) be implemented.
