In April of we performed air barrier testing on 4 military buildings in Indianapolis, IN.

This Whole Building Guarded Test resulted in air leakage rates of 1. We first tested 7 units, unguarded, and the air leakage ranged from 9. However, airtightness measurements can be used to provide air leakage parameters for models of natural infiltration.

Last week we performed air leakage and water leakage testing at f1827 new construction office building in Indianapolis. For specific hazard statements see Section 7. For more information on air barrier testing, please e-mail tdunn thermo-scan.

The goal of the project was to develop a baseline that could be used to determine priorities for energy improvements in these buildings. Test Method E measure natural air exchange rates using tracer gas dilution techniques. Monday, September 23, Air Barrier Test of. A variety of reference pressures for building envelope leaks has been used or suggested for characterizing building airtightness.

Historical Version s – view previous versions of standard. These pressures include 4 Pa 0. We suspect that most of the leakage is coming from conditioned space so we have been experimenting with different testing techniques.


Air Barrier Testing (ASTM E and ASTM E)

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. However this building was so tight that we only ended aztm using 2 of our 3-fan systems. While the building was at pascals, we used 4 technicians with individual blower doors to test each of the 44 units. Such models can estimate average annual ventilation rates and the associated energy costs.

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.

The two-point method uses more complex data analysis techniques and requires more accurate measurements Tables X1.

Air Barrier Testing (ASTM E1827 and ASTM E779)

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. While spraying the exterior, technicians inside the building searched for water infiltration. This standard permits both depressurization and pressurization measurements to compensate for asymmetric flow in the two directions.

Horizontal and vertical seams were checked utilizing a calibrated sprayer unit.

Visit this link to view our new video on YouTube: The measurements of pressure differences and airflows are used to determine airtightness and other leakage characteristics of the envelope. However, when a liquid solution was applied to the tested surface, air movement became very evident. Many multi-family development projects that are tied to tax credits must meet strict energy efficiency standards.

These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of the standard. The buildings were amazingly tight as we are seeing a vast improvement in air barrier details and construction monitoring.


Link to Active This link will always route to the current Active version of the standard. These results can be used to compare the relative airtightness of similar buildings, determine airtightness improvements from retrofit measures applied to an existing building, and predict air leakage. 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.

A 10′ x 10′ air-tight chamber was constructed and sealed tightly to the exterior wall assembly. To measure air change rate directly, aastm Test Method E In most e18827 there is quite a bit of air leakage from unit-to-unit or from the unit to a conditioned hallway.

Posted by Travis Dunn at 8: We performed semi-guarded testing where we set up blower doors in 3 adjacent satm, testing the middle unit while depressurizing the 2 adjacent units to pascals.

Both techniques use an orifice blower door to induce pressure differences across the building envelope and to measure those pressure differences and the resulting airflows. These air change rates account for a significant portion of the space-conditioning load and affect occupant comfort, indoor air quality, and building durability.
