Yes, you still need to provide a purchasing plan to confirm that you have developed a plan for future lamp purchases that meet the credit requirements. If the project building’s currently installed lamps are already below 90 picograms per lumen-hour, you can just copy over the lamp inventory into the purchasing plan table in the credit form. You can adjust the purchasing plan further to get an even lower average mercury-content if desired.

It is not necessary to inventory every lamp installed in the project building. However in order to accurately determine which types and how many lamps should be listed in the purchasing plan, it is necessary to take inventory of at least 90% of the fixture types in the building (including hard-wired, portable, and task lighting). You will also need to inventory the number of lamps associated with each fixture type. Taking an inventory of fixtures will be less time-consuming than an inventory of every installed lamp.

It is rare for a building to have absolutely no mercury-containing lamps installed. However, if this is the case, submit a lamp inventory and manufacturer documentation confirming your claim. Don’t be surprised if your reviewer asks questions.

If a single AHU is supplying outside air to multiple zones through VAV boxes, outside air measurements need to be tested at the AHU level but not a the VAV boxes.

Outside air measurements need to be tested at the system level and so measurements would need to be taken at each AHU, not just the single supply fan.

If the systems do not meet the required outside air during the initial testing the following actions should be taken:

If for some reason you needed to make corrections to the ventilation system in order to meet the ventilation prerequisite during the review process, you could do so without having to reset the performance period for all of the performance based credits like EAp2. Outside air measurements can and must be redone to confirm that the systems meet the prerequisite after the corrections were made.

Page 71 of the LEED-EBOM v2009 Reference Guide outlines a path for Option 3 to comply with the maximum footcandle levels prescribed by IESNA RP-33.

LEED has provivded no specific guidance for this scenario, but here are some options to consider:

The following CIR provides guidance for similar situations within the LEED-NC rating system but specific guidance for LEED-EBOM projects has not been provided by USGBC. The following CIR has not been assessed for applicability for the LEED-EBOM rating system.12/18/2007 - CIRThe applicant is seeking clarification as to the interior/exterior area classification for a four level open air parking ramp building. For the purposes of SSc8, parking structure covered floor area is to be considered interior area and uncovered area is to be considered exterior area.
