Our project involves a new college residence hall with a new parking garage. The two structures are not physically attached (they are separated by a walkway of approximately 25 feet), but they are both included as part of our project site. The parking garage has been sized to accommodate parking for two existing residence halls in addition to the new building, so that approximately one third to one half of the new parking is actually dedicated to our new building. Our question: Can we can pro-rate the energy use and material use of the parking garage based on the actual number of spaces dedicated to our building, even though the garage is included as part of our project site?
As determined by precedent in SSc4 CIR dated 8/30/01, it is acceptable to allocate a portion of the parking garage to the LEED project. Allocate a proportional amount of the parking garage from the ground up (based upon actual number of spaces dedicated to the building), including both the covered and top deck spaces. ASHRAE instructs that garage lighting (0.3 Watts/Sq. Ft) be included in the Energy Cost Budget calculation, but does not acknowledge ventilation strategies. If the project decides to include the garage or a designated portion in its calculation, then to remain consistent it must be included in all other applicable credit calculations. Applicable internationally.
