Air Barrier Testing (ASTM E1827 and ASTM E779)

We then depressurized the entire building to pascals using commercial blower door fans. Test Method E measure natural air exchange rates using tracer gas dilution techniques. We performed semi-guarded ast, where we set up blower doors in 3 adjacent units, testing the middle unit while depressurizing the 2 adjacent units to pascals.

These test methods evolved from Test Method E to apply to orifice blower doors. While spraying the exterior, technicians inside the building searched for water infiltration.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For specific hazard statements see Section 7. Since this air leakage is from conditioned space TO conditioned space, it doesn’t have the energy penalty associated with air leakage to the outsidethere may be other reasons to seal these leaks like odor control, sound transmission, stack effect, etc. The two-point method uses more complex data analysis techniques and requires more accurate measurements Tables X1.


The measurements of pressure differences and airflows are used to determine airtightness and other leakage characteristics of the envelope. These air change rates account for a significant portion of the space-conditioning load and affect occupant comfort, indoor air quality, and building durability.

Wind also causes pressure fluctuations that affect measurement precision and cause the data to be autocorrelated. Utilizing theatrical smoke, there didn’t appear to be much air movement around these small pin holes.

Depressurization is appropriate for testing the building envelope tightness to include the tightness of such items as backdraft dampers that inhibit infiltration but open during a pressurization test. This standard permits both depressurization and pressurization measurements to compensate for asymmetric flow in the two directions.

Pressure gradients over the envelope caused by inside-outside temperature differences and wind cause bias in the measurement by changing the building pressure differences over the test envelope from what would occur in the absence of these factors.

The contractor applied a spray air barrier on the face of the masonry block walls and the building owner was concerned that astj material wasn’t applied thickly enough.

These test methods produce results that characterize the airtightness of the building envelope. In our latest attempt, we performed a Whole Building Air Leakage on a 3-story 44 unit multi-family new construction project. Many multi-family development projects that are tied to tax credits must meet strict energy efficiency standards. Such models can estimate average annual ventilation rates and the associated energy costs. Small pin holes were visible throughout the tested assembly:.


This building has 2 sections: Tuesday, April 7, However this building was so tight that we only ended up using 2 of our 3-fan systems. Based on the square footage of the building, 12 fans should have been required to hit the passing rate. A small fan was used to pressurize and de-pressurize the chamber while a technician used a smoke puffer and liquid solution inside the chamber to identify air leakage sites.

Monday, September 23, Air Barrier Test of. It astmm be used to estimate the building leakage characteristics at building pressure differences as low as 4 Pa 0.

A 10′ x e18827 air-tight chamber was constructed and sealed tightly to the exterior wall assembly. Link to Active This link will always route to the current Active version of the standard.

A variety of reference pressures for building envelope leaks has been used or suggested for characterizing building airtightness. To measure air change rate directly, use Test Method E
