LEED AP O+M · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Performance period length
- LEED O+M certification requires a consecutive 12-month performance period of measured data ending no more than 12 months before the certification submittal date.
- Arc platform purpose
- Arc is the USGBC digital platform where projects upload measured performance data, receive scores, and submit for LEED O+M certification review.
- Recertification cycle
- LEED O+M recertification occurs every three years using the most recent 12 consecutive months of measured performance data available at submittal.
- Certified point threshold
- A LEED O+M project earns Certified at 40-49 points, Silver at 50-59, Gold at 60-79, and Platinum at 80 or more out of 110.
- Regional Priority credits
- Regional Priority credits are zip-code-specific bonus credits selected from a list of priority credits designated for the project's region; each earned RP credit is worth one point.
- Innovation credit sources
- Innovation credits are earned through exemplary performance above credit thresholds or through pilot credits from the USGBC pilot credit library.
- Source energy use intensity
- Energy performance in Arc is measured as source EUI in kBtu per square foot per year and compared to a national median for the same building type.
- ASHRAE Level II audit
- A detailed energy survey that includes analysis of specific efficiency measures with estimated savings and costs, more thorough than a Level I walk-through.
- Advanced energy metering
- Meters recording at one-hour intervals or less, storing at least 36 months of data, and remotely accessible, required for the advanced metering credit.
- ENERGY STAR benchmark score
- A 1-100 score comparing a building's energy performance to similar buildings; 75 or higher is the typical exemplary benchmark for eligible building types.
- Ongoing commissioning requirement
- A commissioning plan, current facilities requirements, and systems manual must be maintained, with a commissioning authority reviewing building systems at least annually.
- Indoor water prerequisite
- The indoor water use prerequisite requires a 20% reduction from the EPAct 1992 fixture baseline calculated using the building's occupancy.
- Outdoor water prerequisite
- The outdoor water use prerequisite requires a 30% reduction from baseline irrigation demand or no permanent irrigation system installed.
- Water metering credit
- Permanent meters measuring total potable water consumption at one-hour intervals or less, with remote data storage of at least 36 months.
- Cooling tower water analysis
- A one-time potable water analysis measuring calcium, magnesium, silica, chloride, and conductivity to determine allowable cycles of concentration.
- Waste diversion rate
- The percentage calculated as material recycled, composted, or reused divided by total waste generated over the performance period.
- Ongoing purchasing credit
- Rewards purchase of products meeting sustainability criteria in categories such as paper, cleaning products, furniture, and electronics, documented by purchase value.
- O+M waste scope
- O+M waste credits cover ongoing operational waste generated during the performance period, not construction and demolition waste.
- Green cleaning product threshold
- At least 75% of cleaning products by cost must meet third-party criteria such as Green Seal or UL ECOLOGO for the green cleaning credit.
- Environmental tobacco smoke prerequisite
- Prohibits smoking inside the building and within 25 feet of entries, outdoor air intakes, and operable windows; designated areas must be signed.
- Occupant comfort survey
- A survey conducted at least once during the performance period; results must be documented and corrective action taken for identified comfort issues.
- Thermal comfort standard
- Thermal comfort in LEED O+M is assessed against ASHRAE Standard 55, while ventilation is assessed against ASHRAE Standard 62.1.
- BUG rating
- The backlight, uplight, and glare rating system used to evaluate exterior luminaires for the light pollution reduction credit.
- Transportation survey
- A survey of occupants capturing commuting mode share, distance traveled, and vehicle miles traveled, entered into Arc for the transportation credit.
- Site management prerequisite
- Requires a site management policy addressing maintenance, snow and ice removal, fertilizer and pesticide use, and exterior cleaning practices.
- LEED AP O+M eligibility
- Candidates must hold a current LEED Green Associate credential and have documented experience on a LEED project within the last three years.
- LEED AP O+M exam format
- 100 multiple-choice questions administered in two hours at a Prometric test center or through online proctoring; passing score is 170 of 200.
- O+M continuing education
- LEED AP O+M holders must earn 30 continuing education hours every two years, including at least 6 hours specific to the O+M rating system.
- Professional conduct agreement
- Credential holders agree to the USGBC credentialing agreement and code of conduct, prohibiting misrepresentation of credentials and requiring accurate project documentation.
- Integrative process credit
- A one-point credit requiring documented discovery analysis of energy and water system synergies performed during the performance period before decisions were finalized.
- Integrative process documentation
- A narrative describing the analysis performed, participants involved, and outcomes that informed operations decisions, submitted through Arc with supporting evidence.
- Prerequisite enforcement
- Every prerequisite in a category used must be met; failing any prerequisite prevents certification regardless of total points earned.
