Air Infiltration Sample Clauses
Air Infiltration. This FIM included locating and sealing gaps in the building envelope system to reduce air infiltration. Gaps were identified during the audit phase. Table 32 outlines the area identified to be sealed in each building. An as-built was supplied by the subcontractor confirming that the air leakage areas were insulated as proposed and therefore used to calculate realized savings. A detailed list of building envelope upgrades for each building can be found in Exhibit A of the Performance Contract Agreement.

Air Infiltration. When included in the scope of work the following standards shall apply.
1. When exposed/uncovered during rehab activities, penetrations of floor, walls, and ceilings, such that occur at access openings, electrical wiring and outlet boxes, plumbing piping, and ducts, shall be sealed to prevent free passage of air between conditioned and unconditioned spaces or the exterior.
2. Air Barriers: Exposed walls in attics, separating the conditioned space of the dwelling unit from the unconditioned space in the attic, shall have an approved air barrier installed on the attic side of the wall.
Air Infiltration test the integrity of the air barrier, and identify sources of air leakage in the existing envelope, by performing air leakage testing in accordance with ASTM E779 “Standard Test Method for Determining Air Leakage Rate by Fan Pressurization,” popularly referred to as the “blower door test.”
Air Infiltration. (Applies only to single acting offset pivot, butt hung or continuous hinged entrances).
