ASTM E779-10 PDF

If you like to setup a quick demo, let us know at support madcad. Air leakage accounts for a significant portion of the thermal space conditioning load. In addition, it affects occupant comfort and indoor air quality. In most commercial or industrial buildings, outdoor air is often introduced by design; however, air leakage is a significant addition to the designed outdoor airflow. In most residential buildings, indoor-outdoor air exchange is attributable primarily to air leakage through cracks and construction joints and is induced by pressure differences due to temperature differences, wind, operation of auxiliary fans for example, kitchen and bathroom exhausts , and the operation of combustion equipment in the building.

If you like to setup a quick demo, let us know at support madcad. Air leakage accounts for a significant portion of the thermal space conditioning load. In addition, it affects occupant comfort and indoor air quality. In most commercial or industrial buildings, outdoor air is often introduced by design; however, air leakage is a significant addition to the designed outdoor airflow.

In most residential buildings, indoor-outdoor air exchange is attributable primarily to air leakage through cracks and construction joints and is induced by pressure differences due to temperature differences, wind, operation of auxiliary fans for example, kitchen and bathroom exhausts , and the operation of combustion equipment in the building. The fan-pressurization method is simpler than tracer gas measurements and is intended to characterize the air tightness of the building envelope.

It is used to compare the relative air tightness of several similar buildings to identify the leakage sources and rates of leakage from different components of the same building envelope, and to determine the air leakage reduction for individual retrofit measures applied incrementally to an existing building, and to determine ventilation rates when combined with weather and leak location information. This test method does not measure air change rate or air leakage rate under normal weather conditions and building operation.

Note 1See Test Method E to directly measure air-change rates using the tracer gas dilution method. For the purpose of this test method, many multi-zone buildings can be treated as single-zone buildings by opening interior doors or by inducing equal pressures in adjacent zones. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Building envelope testing in existing buildings

The air pressure testing procedure for new buildings is fairly straightforward and has several testing standards to follow see below , but testing of existing buildings is another matter. Existing buildings cannot be tested under the same protocols as new buildings, so you have to approach an existing building from many different angles to achieve the end goal. To effectively test a new building, the first task is to specify under what standard the building will be tested and what acceptable leakage rate will be applied to the test. These standards have been used as the basis for U. For example, ASTM E is a multipoint test that takes flow measurements at 10 different pressures from 10 Pa to at least 60 to 75 Pa.
