Encouraging tenant sustainability efforts

This credit is intended to help Core and Shell projects educate tenants about the base building sustainable design and ways tenants might enhance the sustainability of their tenant spaces, including support for earning LEED-CI.

Tailor your guidelines to fit your project

Support comes in the form of tenant guidelines, which LEED-CS projects must write and submit in order to earn this credit. The guidelines could entail information about lighting efficiency and design, non-toxic paints, water-efficient fixtures, and numerous other topics covered by LEED.

Why open space?

This credit is intended to promote sites with large areas of vegetated open space that promote biodiversity and recreation—which can also add an amenity to your project, help with natural stormwater management, and mitigate the urban heat island effect.

You may have already earned this credit

You already addressed this credit as part of the compliance process for IEQp1: Minimum Indoor Air Quality Performance. If the measurements you took for IEQp1 indicate that your building has ventilation rates that are at least 30% better than ASHRAE 62.1-2007 for every ventilation distribution system, no further action is required, other than checking that any needed documentation is uploaded.

If, on the other hand, your ventilation rates are not at least 30% better than ASHRAE 62.1-2007, you’ll need to consider whether it is appropriate to pursue this credit.

A lot is at stake here

EAc1: Optimize Energy Performance is, by far, the most important credit in LEED, based on the number of points available. Up to 21 points are at stake here based on how much you’re able to reduce the project’s predicted energy cost. That large amount of points also reflects the great importance LEED places on reducing energy use and forestalling climate change.

Check if you are affected by a key update

USGBC's membership approved an update to LEED 2009 effective April 8, 2016. The update only affects LEED 2009 projects registered on or after that date.

Project teams will be required to earn a minimum of four points in EAc1, effectively making part of this credit a prerequisite along with EAp2. The referenced energy standard and modeling requirements are not changed. Buildings falling under the proposed change can use the same methodologies and referenced standards, but will need to earn additional points in order to achieve certification.
