GIB Credit 1: Certified green buildings
Intent
To encourage the design, construction, and retrofit of buildings that utilize green building practices.
Requirements
OPTION 1. Projects with 10 or fewer habitable buildings
Design, construct, or retrofit one building as part of the project, beyond the prerequisite, to be certified under one of the following LEED green building rating systems: LEED for New Construction, LEED for Existing Buildings, LEED for Homes, LEED for Schools, LEED for Retail: New Construction, or LEED for Core & Shell (with at least 75% of the floor area certified under LEED for Commercial Interiors or LEED for Retail: Commercial Interiors) or through a green building rating system requiring review by independent, impartial, third-party certifying bodies that have either been accredited by an IAF accreditation body to, or could demonstrate compliance to, ISO 17021 or ISO/IEC Guide 65, and, when subsequently available, ISO/IEC 17065.
OR
OPTION 2. Projects of all sizes
Design, construct, or retrofit a percentage of the total project building square footage, beyond the prerequisite requirement, to be certified under one of the LEED green building rating systems listed above or through a green building rating system requiring review by independent, impartial, third-party certifying bodies that have either been accredited by an IAF accreditation body to, or could demonstrate compliance to, ISO 17021 or ISO/IEC Guide 65, and, when subsequently available, ISO/IEC 17065.
Table 1. Points for green building certification
Percentage of square footage certified Points ≥ 10% and < 20% 1 ≥ 20% and < 30% 2 ≥ 30% and < 40% 3 ≥ 40% and < 50% 4 ≥ 50% 5
AND
For all projects
Detached accessory dwelling units must be counted as separate buildings. Accessory dwellings attached to a main building are not counted separately.

Will a BREEAMBuilding Research Establishment Environmental Assessment Method, the first widely used green building rating system, developed in the U.K. in the early 1990s, currently used primarily in the U.K. and in Hong Kong. certified building in an ND project count towards LEED GIB prerequisite one?
Equivalency to the ISO standards in GIBp1/c1 is being handled on an individual case basis, as we've had few projects attempt it so far. You would submit a project-specific CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide outlining how BREEAMBuilding Research Establishment Environmental Assessment Method, the first widely used green building rating system, developed in the U.K. in the early 1990s, currently used primarily in the U.K. and in Hong Kong. meets the requirements of one of the ISO standards. Start with this guidance document, found in the Resources tab of GIBp1 in the LEED Credit Library: https://new.usgbc.org/node/1732035?view=resources

Only LEED CS inside proj. boundary
Considering that we have 6 LEED CS-certified buildings inside project boundary. One LEED CS building will have LEED for Commercial Interiors in 75% of its area and is counted towards prerequisite achievement - GIBp1.
Must the other 5 LEED CS buildings have 75% of their area under LEED for CI certification to get points under GIB credit 1 achievement? I assume that this 'rule' (75% CI for a CS) is applied only for prerequisite compliance, right?
Hi Karyn. The same rule applies to the credit, as listed in the credit requirements. If your project has a particular hardship with this requirement, please talk to your reviewer at GBCI about the specifics.
Best,
Meghan
Points under option 1
Credit language does not state how many points you will get when you certify one single building under LEED rating systems. We would appreciate any clarification.
Alicia, under GIBc1 if your project has 10 or fewer buildings, then the last sentence of Option 1 provides one point for one certified building beyond the GIBp1-required building. Also, GIBc1 Option 2 is available to any project regardless of the number of buildings, but points are based on the percentage of total project floor area that's certified as shown in Table 1 of the credit.

How to identify third-party certifying bodies?
As subject indicated, how to identify third-part certifying bodies as defined by ISO/IEC 17021.
Both GIBp1 and GIBc1 document guidance advise to assemble information about the building's green certification, does it include related documents about the ISO/IEC certificates or something others?
What kind of a detailed infomation should we to seek and where can we get the qualified ISO/IEC certifying bodies?
In China, goverment publish an official green building rating system,
Shenhao, GIBp1 and c1 require that buildings be certified by a LEED program, or by a program that has either been accredited by an IAF accreditation body or that can demonstrate compliance with applicable ISO standards for independent, impartial, third-party certification reviews. A LEED-ND rating system addenda regarding this requirement is available at http://www.usgbc.org/ShowFile.aspx?DocumentID=7048. You should also review the GIBp1 supplemental guidance available at http://www.usgbc.org/ShowFile.aspx?DocumentID=9543.
For GIBp1 and c1 buildings, a LEED-ND submission must include confirmation that the buildings have been LEED registered or certified depending on project stage, or confirmation that the buildings have been registered or certified through an alternative certification program that meets applicable ISO requirements.
If you are interested in using a Chinese certification program, you should first inquire about its international accreditation status, and then I recommend you share that information with USGBC technical assistance staff to determine whether in their opinion the Chinese program meets the GIBp1/c1 requirement.
