OPR - Owner’s Program Requirements
The set of goals and requirements defined by the owner or client. This program includes the information needed for the project team to start the pre design phase. It describes:
(1) project goals,
(2) environmental vision,
(3) budget,
(4) schedule and
(5) physical properties of a project’s internal and external spaces.
BOD - Basis of Design
The information included in the OPR such as:
(1) systems descriptions,
(2) Environmental Quality (EQ) criteria,
(3) design assumptions and
(4) applicable codes in technical terms.
Adaptive Reuse
Reusing buildings for a different purpose other than the first one they were built for
Regenerative Projects
- Net Zero Energy - use no more electricity than it generates onsite
- Net Zero Carbon Footprint - net zero carbon emissions
- Water Balance - uses only water received by precipitation
- Zero Waste - reuses, recycles or composts all wastes
Commissioning Agent or Authority (Cx)
Ensures that the OPR are included in the design process and that the building systems are installed and designed properly.
LEED describes who can be the project’s commissioning agent and their responsibilities through design phases. As a minimum, LEED requires the commissioning of energy systems of the project and results in reduced energy use, reduced contractor callbacks, better building documentation and system verification.
Operations & Maintenance Program
O&M includes training the facility manager, project owner and building occupants on how to operate the building and to optimize its performance while avoiding system degradation.
LEED for Neighborhood Design
5 credit categories:
- Smart Location & Linkage
- Neighborhood Pattern & Design
- Green Infrastructure & Buildings
- Innovation & Design Process
- Regional Priority Credits
Credit Categories
- Location and Transportation (LT)

- Energy and Atmosphere (EA)
- Materials and Resources (MR)
- Indoor Environmental Quality (EQ)
- Innovation in Design (ID)
- Regional Priority (RP)
Impact Categories
Used to weigh credits
- Reverse contribution to climate change
- Enhance human health & wellbeing
- Protect and restore water resources
- Protect biodiversity and ecosystem services
- Promote sustainable and regenerative resource cycles
- Build a greener economy
- Enhance community, social equity, environmental justice & quality of life
MPRs - Minimum Program Requirements
3 main goals:
• Customer guidance and understanding
• Reinforce LEED’s integrity
• To minimize challenges throughout the LEED certification process
Each rating system has 3 identical MPRs:
- Must be in a permanent location on existing land
- Must use reasonable LEED boundaries
- Must comply with project size requirements (GFA)
Value Engineering
Cutting project costs, often during construction phases affecting the actual value of the project.
LEED Rating Systems
- LEED for New Construction
- LEED for Core & Shell
- LEED for Existing Buildings: Operations & Maintenance
- LEED for Homes
- LEED for Neighborhood Development
- LEED Campus
- LEED Volume
3 phases of credit applications
- Predesign - Discovery
- Schematic Design - Design & Construction
- Feedback Mechanisms - Operations & performance monitoring
LEED Interpretations
Precedent setting version of Credit Interpretation Ruling
ACP - Alternative Compliance Path
If the project team believes they satisfy the credit’s intent through a method outside of the existing reference guide they can submit documentation explaining credit compliance.
