Extracted Content

• Emergency support systems . Emergency support systems generate electricity, heating, or cooling upon failure of the primary system in a power outage or extreme temperature event.

o To apply the exemption, the sequence of operations must specifically limit

emergency support system operations to emergency events associated with power disruptions or extreme temperatures falling outside of ASHRAE 99% design conditions for a prolonged period.

o Emergency power systems are not exempt for locations where power outages

commonly occur for more than 200 hours per year.

• Portable equipment . Exclude portable equipment for outdoor cooking amenities or outdoor patio heating not in the project scope when limited to less than 200 hours per year. Do not permanently pipe fuel lines to the equipment.

• Special circumstances . Use limited on-site combustion for specialty cases where onsite combustion is integral to system function. Examples include:

o Portable laboratory equipment

o Wood-fired ovens in commercial kitchens fitted with emissions control devices

o Vocational schools using fossil fuels solely for the purpose of training

o Electric incinerators for medical waste

o Fireplaces, hearths, and fire pits exclusively designated to support ceremonial

practices (such as those unique to indigenous cultures or religious practices that require the use of fire)

These special circumstances do not extend more broadly to process equipment except where approved on a project-specific basis for systems with very low greenhouse gas emissions.

Platinum Requirements

Projects aiming to achieve LEED Platinum certification must meet the following criteria applicable to the project type.

- **New Construction** . Achieve five points. (no on-site combustion)

- **Core and Shell** . Achieve four points. (no on-site combustion)

- Projects served by District Energy Systems. Refer to the Project Priorities Library for

DES compliance paths.

The Platinum requirements intentionally encompass industrial and manufacturing processes. To obtain Platinum certification, on-site boilers used for manufacturing production must comply with the credit criteria.
