Air Barrier Testing (ASTM E1827 and ASTM E779)
Posted by Travis Dunn at 1: TSI just performed an air barrier test of a 37, sf building for the Army Corps. Many multi-family development projects that are tied to tax credits must meet strict energy efficiency standards. While the building was at pascals, we used 4 technicians with individual blower doors to test each of the 44 units.
These pressures include 4 Pa 0. The contractor applied a spray air barrier on the face of the masonry block walls and the building owner was concerned that the material wasn’t applied thickly enough. Combining the results of depressurization and pressurization measurements can minimize wind and stack-pressure effects on calculating airtightness but may overestimate air leakage due to backdraft dampers that open only under pressurization.
Link to Active This link will always route to the current Active version of the standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Tuesday, April 7, We then depressurized the entire building to pascals using commercial blower door fans. 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 asm envelope from what would occur in the absence s1827 these factors. 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. In April of we performed air barrier testing on 4 military buildings in Indianapolis, IN.

Posted by Travis Dunn at 8: A ee1827 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.
The largest building had a building envelope area well overs. The two-point method uses more complex data analysis techniques and requires more accurate measurements Tables X1. These air change rates account for a significant portion asym the space-conditioning load and affect occupant comfort, indoor air quality, and building durability.
Small pin holes were visible throughout the tested assembly:.
The measurements of pressure differences and airflows are used to determine airtightness and other leakage characteristics of the envelope. Last week we performed air leakage and water leakage testing at a new construction office building in Indianapolis. Test Method E measure natural air exchange rates using tracer wstm dilution techniques.
The Whole Building Air Leakage Test allows us to demonstrate the air leakage from each apartment unit to the outsidewhile neutralizing air leakage from conditioned space to conditioned space.
For specific hazard statements see Section 7. This building has 2 sections: This standard permits both depressurization and pressurization measurements to compensate for asymmetric 1e827 in the two directions.
For nonorifice blower doors or for e827 too large to use blower doors, use Test Method E The buildings were amazingly e182 as we are seeing a vast improvement in air barrier details and construction monitoring.

Air Barrier Testing (ASTM E and ASTM E)
The reduced air leakage rates we demonstrate significantly impact HERS scores. To measure air change rate directly, use Test Method E We performed semi-guarded testing 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. However, airtightness measurements can be used to provide air leakage parameters for models of natural infiltration.
Using a hi-lift, we performed a water leakage test following AAMA A 10′ x 10′ air-tight chamber was constructed and sealed tightly to the exterior wall assembly.
These test methods produce results that characterize the airtightness of the building envelope. Horizontal and vertical seams were checked utilizing a calibrated sprayer unit.
However this building was so tight that we only ended up using 2 of our 3-fan systems. Monday, September 23, Air Barrier Test of.
While spraying the exterior, technicians inside the building searched for water infiltration. We built our testing chamber on the exterior of the asttm to examine a small portion of the completed wall: Therefore, airtightness measurements using aatm test methods cannot be interpreted as direct measurements of natural infiltration or air change rates that would occur under natural conditions.
Historical Version s – view previous versions of standard. A variety of reference pressures for building envelope leaks has been used or suggested for characterizing building airtightness.
Based on the square footage of the building, 12 fans should have been required to hit the passing rate. Use of this standard in conjunction Practices E permits the identification of leakage sources and rates of leakage from different components of the same building envelope. We suspect that most of the leakage is coming from conditioned space so we have been experimenting with different testing techniques. These results can be used to compare the w1827 airtightness of similar buildings, determine airtightness improvements from retrofit measures applied to an existing building, and predict air leakage.
