"LEED Interpretation" "1767" "2007-04-20" "New Construction, Commercial Interiors, Core and Shell, Schools - New Construction" "USGBC has previously stated that if a product is inside the exterior moisture protection, it is a controlled product (it must comply with the credit requirement). Our question concerns the adhesive used to adhere to the concrete the ""stick pins"" that hold up the insulation to the underside of the concrete slab that forms the garage ceiling. Technically, this area is inside the exterior moisture protection envelope, but garage is not a regularly occupied space, and the concrete slab provides an impenetrable barrier between the stick pins/adhesive and the occupied spaces above. The garage is below and adjacent to occupied space. At the adjacent condition, the garage is separated from the occupied space either by solid wall, intervening utility spaces or a vestibule. The garage has variable active ventilation by two exhaust shafts with fans that are controlled via CO2 detectors. These shafts are located in the southwest and northwest corners of the garage. Distribution fans are also located in opposite corners, etc to move air towards the exhaust fans. Fresh air is brought into the garage via numerous openings along the full length of the east wall and a centrally located fresh air shaft. The adhesive used for this purpose has a VOC content of 420 gm/L, and we have not been able to find an acceptable substitute with a VOC content within the maximum 250 g/L assigned to the ""All Others"" category of Table 1 of the LEED-NC version 2.1 Reference Guide. (No other category of Table 1 applies.) Given that the product will be used in a non-conditioned, non-regularly occupied space; that there is no acceptable alternative for this application; the presence of the impenetrable concrete stab, and the long duration between application and occupancy of this multi-story project, we request that this application/product be exempted from the requirements of EQ 4.1." "The project is inquiring if an adhesive used within the exterior moisture protection, but above an impenetrable concrete deck in an unconditioned, non-regularly occupied space, is exempt from EQc4.1. The project may exclude the adhesive in question since 1) the garage is open to the outdoors at all times and thus is not technically an interior space and 2) the occupied areas of the building are separated from the garage by solid, impenetrable walls.

" "None" "None" "X" "LEED Interpretation" "758" "2004-04-19" "New Construction, Commercial Interiors, Core and Shell, Schools - New Construction" "HVAC duct work is generally installed once the building has walls and a roof, but before windows are installed. It is our project team\'s understanding that the building would not be considered to have indoor air at this time, but since this inquiry deals with the indoor air distribution system, we want to be certain that we will comply with the credit requirements. In climates with freezing temperatures over the winter months, water based duct sealants (which comply with VOC limits) are not acceptable for use due to the fact that they will crack when frozen. Oil-based sealants (which do not comply with VOC limits) are required in freezing weather until the building is enclosed and thermally controlled. It is not clear to this project team whether or not SSc4.1 would apply to sealing the duct work. When, during the construction process, does SSc4.1 start to apply, and does SSc4.1 apply to duct sealants?" "Duct sealants must be included under this credit. The VOC limit requirements of EQc4.1 for adhesives and sealants apply to all phases of construction. The LEED-NC v2.1 Reference Guide states on page 276 that this credit applies to products and installation processes that have the ability to adversely affect indoor air quality on site: and those that are exposed in interior spaces accessible by occupants (meaning all space within the weatherproofing layer of the building envelope). The VOCs from this product will offgas long enough to effect the building\'s indoor air quality. In addition, installers are immediately exposed to the product\'s emissions.
