Yes. A project can earn an Innovation point for Exemplary Performance while also earning an RPc1 point for the same credit.

A project can receive a maximum of four points, even if all six possible Regional Priority credits are achieved.

Portable fire extinguishers are not required to be included in EAp3 or EAc4.

The project team must use equipment life values from the 2007 ASHRAE Applications Handbook as listed in the LEED Reference Guide. For equipment not listed in the ASHRAE Applications Handbook, the equipment life must be assumed to be 15 years—no estimates are allowed. An alternative equipment life may only be used if a manufacturer’s guarantee and equivalent long-term service contract can be provided. 

While a phase-out is allowed in the prerequisite, EAc4 is like other credits where the credit should be achieved as part of the LEED scope of work. The work should be completed during construction.

The system capacity should be based on the outdoor units. If you have multiple interior devices connected to one outdoor unit, the cooling capacity should be for the outdoor unit, but the refrigerant charge must include all interior devices.

The system capacity should be based on the outdoor units, while all parts of the system including outdoor, indoor units, branch selectors and piping should be counted for the total refrigerant charge.


Any permanently installed piece of equipment containing greater than 0.5 lbs. of refrigerant and included in the project scope should be included in calculations.

All HVAC&R equipment that will serve the project building should be included in the calculations.

Only the default leakage rate of 2% is accepted in the credit calculations.
