To document the credit, develop a floor plan showing the location of existing structural components, floors, roof deck, exterior walls, and internal structural walls, and identify each that are reused. See the Documentation Toolkit for an example floor plan and elevation.
If smoking is to be allowed in certain areas (Case 1, Option 2 and Case 2), fill out LEED template and upload all supporting documentation to LEED Online.
Conduct blower door tests, which in multifamily and hotel applications typically require a sampling of one out of every seven units. See the Home Energy Rating System program (link) for details on sampling rates. For any spaces that do not pass the blower door pressure test, correct any potential problems and retest, or another space has to be tested until 100 percent of the requisite number of spaces have successfully passed.
The contractor schedules any necessary air pressure or blower door tests in their proper sequence. Testing occurs at various construction phases and ideally with a test unit to identify any leakages and opportunities for improvement in other units.
If smoking is to be allowed in certain areas (Case 1, Option 2 and Case 2), integrate deck-to-deck partitions and weatherstripping or pressurization into plans and construction document specifications.
In non-residential construction when smoking will be banned (Case 1, Option 1), incorporate smoking-related signage into plans and construction specifications. Fill out LEED Credit Form and upload all supporting documentation to LEED Online.
The mechanical engineer ensures that the HVAC design meets the exhaust and pressure levels of the LEED requirements. Also ensure that all units will receive adequate fresh air. A certain amount of air
