FAQs about EAc6 :

The owner has purchased RECs for a percentage of energy use of its whole portfolio of buildings, or campus. Can we earn this credit for a single LEED building with this purchase?

We plan on pursuing this credit only if we need to do so to meet our certification target, i.e. if another credit we are counting on gets rejected. How late can we apply for this credit?

The owner purchases RECs based on an earlier prediction, but our energy model is now showing that we are just a little short of the credit threshold. What should we do?

Our project is outside the U.S. We would like to earn this credit by purchasing RECs, but there are no Green-e options available here. It looks like most Green-e certified power comes from the U.S. What should we do?

We are pursuing this credit outside the U.S., and the owner wants to know if we can buy green power through a provider in our country that is not Green-e certified. We started comparing our national standard to Green-e and quickly found an area where the

Our project will be net-zero energy, i.e. will produce as much or more power than it consumes. Can we earn this credit?

Hello, Our company has a Project (in Santiago Chile) and we have a question about the additional requirement calculation for CS Core and Shell Credit 6, Green Power. The credit says that gross SF for core and shell is the complete area of the building without parking lots. So… what we need to add for usable square footage (USF)…just regularly occupied spaces or maybe another space’s? Thank You. Fernanda

Usable square footage sounds like net square footage which is all of the spaces inside the building not including exterior walls, partitions, shafts, etc.

Hi Fernanda, According to this BOMA glossary of terms (https://goo.gl/ikupfO), the total usable area (ANSI/BOMA Z65.1-2010). is defined as occupant area plus building amenity areas. Occupants include tenants as well as owner-occupants. Building amenity areas include only those amenities that are convertible to Occupant Area and are not required by code or for the operation of the building. Shared conference rooms, exercise areas/fitness centers, child care centers, and vending areas are classified as Building Amenity Areas. The BOMA 1996 Office Floor Measurement Standard defined usable area as office area plus store area plus building common area. Usable area does not include Building Service Areas, such as building lobby and corridors; fire control center and equipment; restrooms and janitors’ closets; mechanical, electrical and communications rooms and closets; truck loading, receiving and trash; or building management and maintenance. I hope that helps.
