The Boundary Question on a Mixed-Use Block
An owner is renovating an eight-story 1920s building. Floors 2–8 will be office space; the ground floor is leased to a bank under a long-term triple-net lease with its own utility meter. A basement parking garage is shared with the adjacent hotel and accessed from a different street. The owner wants LEED BD+C certification for the office portion only to avoid dealing with the bank and hotel. The design team has already drawn the LEED boundary around floors 2–8 and excluded the garage. The contractor asks whether this boundary will hold during certification review.
1. How should the project team evaluate the proposed LEED project boundary, and what are the risks of the current approach?
Read the worked answer
Start from the Minimum Program Requirements, not from the credit scorecard. A LEED project must be a complete, permanent building or space, use a reasonable site boundary, and comply with applicable environmental laws. The boundary cannot be drawn to exclude inconvenient areas simply because they are leased or separately metered.
- If the certification scope is truly the office tenant spaces, the correct rating system is likely LEED ID+C: Commercial Interiors, not BD+C for a partial building.
- If the owner wants BD+C, the project boundary should generally include the whole building and associated site, including the bank space if it is part of the same building. The shared garage needs a documented ownership/control analysis: if it serves the project and is within the reasonable site, excluding it requires a defensible narrative, not convenience.
- The risk is MPR noncompliance, rejected energy and water credits, a costly appeal, and a split-incentive problem where the owner cannot obtain whole-building data.
2. The bank will not share utility data and refuses to fund any upgrades. What options does the owner have?

The owner should align the certification scope with actual control and data access.
- Choose ID+C for the office spaces if the owner controls only those interiors. That scope has its own metering and energy-performance rules and avoids claiming whole-building performance the owner cannot document.
- Keep BD+C only if the owner can obtain aggregate energy data. That may require a lease amendment, a tenant submeter, a green lease clause, or a shared-savings agreement.
- Do not exclude the bank space solely to make the energy credit easier; that is the kind of boundary manipulation reviewers look for.
The judgment call is scope selection: certification type should follow control, not the other way around.
3. What documentation would demonstrate a defensible boundary?
Read the worked answer
Build a boundary package that a reviewer can follow without guessing:
- Site plan and floor plans with the LEED boundary clearly marked, including any excluded areas and the reason for exclusion.
- Ownership and lease documents showing who controls each area and who pays each utility.
- Utility account list and meter diagram, including tenant submeters and the shared garage.
- A narrative explaining why any excluded area is not part of the project and how the boundary is still reasonable and consistent.
- Energy model and water-use calculations that match the stated boundary.
- Owner commitment to provide data and maintain performance.
If the narrative sounds like credit avoidance rather than a real project scope, the team should revisit the rating-system choice.
