No, the policy only has to cover purchasing performed by the building and site management. You don’t need to impose purchasing requirements on your tenants. Be sure to state the scope of your policy clearly to avoid confusion (in this case, purchases under the building management’s control). Remember that you do have to account for tenant purchases if you attempt any of the credits (with the exception that you can exempt up to 10% of the building’s floor area).

You do not need to attempt or achieve any purchasing credits to earn the prerequisite. Achievement of this prerequisite is based only on whether you create a compliant policy; no purchasing activity or documentation of compliance with the credits is required.

You can submit an existing policy with an amendment or attachment that addresses the missing requirements, as long as all new sections are officially adopted along with your existing policy. You may want to consider highlighting the required elements that are covered in your existing policy so that the LEED review team can easily confirm that you’ve addressed everything.

Yes, all lamps in the project building and site need to be included, unless they meet the exception criteria. This credit may be challenging to achieve on this type of project.

Reference Guide correction ID# 100002036 (released 10/1/2015) removes the requirement to purchase lamps during the performance period. Based on the correction language, it appears that teams can simply confirm that no lamps were needed. However, it is unclear whether teams should also confirm that existing installed lamps meet the credit threshold when pursuing this option. You may want to provide a lamp inventory (e.g., the “lamp purchasing plan” from EBOM 2009) to demonstrate that the overall building average is 70 picograms of mercury per lumen-hour or less.

Screw-based, integral self-ballasted compact fluorescent lamps can be excluded if they meet the voluntary guidelines for maximum mercury content published by NEMA. The guidelines are such that:

Lamps with input wattage of 0 ≤ 25 watts must have 4mg total mercury or lessLamps with input wattage of 25 ≤ 40 watts must have 5mg total mercury or less

If the manufacturer documentation confirms the mercury content is below these maximum mercury content values, than the lamps may be excluded.

No, 90% of all lamps types in the entire must be included. Tenant spaces may not be excluded. Achieving this credit in this situation can be challenging.

Yes, all mercury-free lamps can be excluded from the purchasing plan. However, it might be a good idea to include a narrative explaining why all outdoor light fixtures have been excluded, so that the reviewer knows that you didn’t ignore or forget outdoor fixtures.

Mercury-free lamps (such as LEDs) do not need to be included in purchasing plan, and can only be included if they are more efficient than their mercury-containing counterparts If you would like to include mercury-free lamps in the purchasing plan, you must provide documentation confirming that those lamps are in fact more efficient than their mercury-containing counterparts. Therefore, if you are unable to obtain that documentation, it is best to not include mercury-free lamps in the purchasing plan.

Yes, lamps for task lighting should be included in the purchasing plan - unless they account for less than 10% of the total lamp building lamp inventory, then you can exclude them. Screw-based CFLs that meet NEMA guidelines may be excluded as well.
