The third new bullet should read: "Filtration media has a minimum dust spot efficiency of 80% or higher and greater than 98% arrestance on a particle size of 3-10

Replace the definition of "refrigerants" with "are the working fluids of refrigeration cycles that absorb heat from a reservoir at low temperatures and reject heat at higher temperatures."

Replace the definition of "cul-de-sac" with "a segment of the circulation network that terminates without intersecting another segment of the circulation network."

In the definition of planned diverse use, delete: "outside the project boundary"

At the end of the “Requirements” section in each of the BPDO credits, change text to the following:
“Structure and enclosure materials may not constitute more than 30% of the value of compliant building products. Projects with significant amounts of structural and enclosure materials may exceed the 30% limit by calculating an alternative structure and enclosure limit (See Equation 3 under Further Explanation).”

Add the following to the end of the LEED Certification Process section:

There are also two alternative certification processes for owners with multiple spaces pursuing LEED certification, (1) LEED volume certification and (2) LEED campus certification. In some cases the LEED campus certification is used to achieve one single certification for many spaces on nonconsecutive floors within a single office building with similar fit-out (group certification project) and in others it used to achieve pre-approval for credits to be utilized by a number of certifications (campus credits).

In the third sentence change ‘high-volume exterior entrance’ to ‘regularly used exterior entrance' to read: "However, if the project scope includes an entrance that would qualify as regularly used exterior entrance, then the team must ensure that appropriate entryway systems are also installed."

BD+C:
Option 1, under naturally ventilated spaces, change B to D
Option 2, 2,under naturally ventilated spaces, change B to D and C to E.

ID+C:
Option 1, under naturally ventilated spaces, change B to D
Option 2, under naturally ventilated spaces, change B to D and C to E; under mixed-mode systems, change C to D and D to E.

Remove the definition for "Measurement and Verification". It is a relic from v2009 and should not be included in this reference guide. Strike the entire paragraph that reads:

"Measurement and Verification
Describe the building’s measurement and verification plan, including the International Performance Measurement
and Verification Protocol option and how the Core and Shell measurement and verification plan will be carried out.
Provide information about protocols that tenants can use to create their own measurement and verification plans."

BD+C, ID+C reference guide: Revise the Group Approach section to read: "Eligible. The percentage reduction can be based on the total combined water use reduction in all LEED project buildings. If nonpotable water systems will be shared by multiple projects, ensure adequate supply to meet the demands of all projects using nonpotable water. The nonpotable water may not be double-counted among projects. Submit separate documentation for each building, as required for WE Prerequisite Indoor Water Use Reduction. "
