|
|
Can products be LEED certified? |
No, they simply help achieve various credits. |
|
|
LEED for New Construction (NC) |
New Commercial Buildings including: Retail Office Institutional Hotel Or existing bldg w significant envelope and HVAC renovations |
|
|
LEED for Existing Buildings Operations and Maintenance (EBOM) |
Only rating system that requires certification every 5years. Applies to: Owner occupied bldg Single & multi-tenant bldg Multiple bldg projects Bldg previously certified under LEED NC |
|
|
LEED for Core & Shell (CS) |
Only system that allows for pre-certification to help projects attract tenants before construction completion. CS is typically used when developer does not control interior fit-out. CS may or may not include MEP systems. If developer plans to occupy, owner must occupy no more than 50% to be eligible for LEED CS, otherwise LEED NC. |
|
|
LEED for Existing Buildings Operations and Maintenance (EBOM) |
Only rating system that requires certification every 5years. Applies to: Owner occupied bldg Single & multi-tenant bldg Multiple bldg projects Bldg previously certified under LEED NC
EBOM must fulfill the following: Meet minimum occupancy requirements. Be continuously occupied for 12 months. Use performance periods to measure results and progress over a set amount of time. Develop bldg policies that include a plan for monitoring progress and results as well as following structure: Scope, Performance Metrics, Goals, Strategies, Responsible Parties, and Time Period. |
|
|
LEED for Schools |
Only system that addresses acoustics as a prerequisite |
|
|
LEED for Homes |
Only rating system that includes adjustment for square footage to discourage “green” mansions. |
|
|
LEED for Campus |
Two approaches to certifying campus buildings: 1. Group Approach - allows bldg that are substantially similar and are in a single location to serifs as one project sharing single certification. 2. Campus Approach - allows bldg that share single location and site attributes to achieve separate LEED certifications for each project on the master site. |
|
|
Minimum Program Requirements (MPR) that are additional to project prerequisites to be LEED-compliant |
1. Bldg must be in permanent location on existing land. 2. Reasonable LEED boundaries: Includes all contiguous land that is associated w project and supports typical operations. Does not unreasonably exclude portions of the bldg, space, or site to give project and advantage. Accurately communicates the scope of the project and distinguishes it from any non-certifying space. 3. Must comply w project size requirements: 1000 sq.ft. for LEED BD+C & EBOM 250 sq.ft. for ID+C |
|
|
Parameters of LEED Site Boundary |
1. Non-contiguous parcels of land may be included within the LEED project boundary if the parcels are directly associated w normal bldg operations of the LEED project and are accessible by LEED project occupants. 2. Facilities such as parking lots, bike storage, showers, cleaning facilities, and/or onsite renewable energy that are outside of the LEED boundary may be included in certain prerequisites and credits if they directly serve the LEED project and are not double-counted in another LEED project. 3. LEED project should include entire bldg and complete scope of work. 4. Bldgs primarily dedicated to parking are not eligible for LEED. Parking that serves a LEED bldg should be included in certification. 4. LEED boundary can be different than property boundary and development footprint. |
|
|
Steps to LEED Certification |

|
|
Registering a LEED project requires info |
Title. Location and address. Construction start and end. Rating system (cannot be changed after registration). Number of proj to be registered. Gross project SF. Confidential (Y/N). Project program. Anticipated certification level. |
|
|
LEED registration and certification costs |
Project Registration Cost: 1200 members / 1500 non-m Certification Cost: Based on membership & project size. Not on cert. level, budget, or location. Other costs: $220 for credit interpretations $500 for credit appeals |
|
|
Hard Cost |
Purchase price of hard asset such as land, bldg, inventory, equipment or machine. |
|
|
Soft Cost |

1. Site Plan 2. Floor Plans 3. Elevations 4. Renderings 5. Project Description 6. Photos of completed project |
|
|
Credit Interpretation Requests (CIRs) |
Each CIR is $220. CIRs are typically specific to one project and may only reference one credit. CERs submitted through LEED online. CIR text limited to 600 words. CIR are reviewed and ruled on by the Technical Advisory Group (TAG). |
|
|
LEED Interpretations |
Official answers to technical inquiries about implementing LEED on a project. Similar to CIRs, difference is that LEED interpretations are precedent setting, meaning they’re applied to all future LEED projects. Categories include: Precedent setting Published online Consensus-based review |
|
|
Submitting project for review |
1. Complete templates, project team admin submits project tonUSGBC for initial review. 2. Within 25 days, initial comments. Credits listed as achieved, denied, pending clarification. 3. Project team 25 days to provide requested docs and/or appeal ruling. Initial appeals are free. 4. USGBC issues final ruling. ($500 per credit appeal after final review). |
|
|
Design Review vs. Construction Review |
Most of time, project team submits all credits at the end of construction phase, though it’s possible to break portion into design review. Advantage to splitting up credits half-half is to receive design review comments in time to make any necessary changes. Certification fees remain the same. |
