LEED AP O+M study plan

LEED AP O+M · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

LEED v4.1/v5 O+M rating system fundamentals (integrative process, location and transportation, sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, innovation, regional priority) & Credential process and standards: eligibility, exam administration, and LEED professional conduct

  • Map every LEED O+M credit category to its prerequisites and point ceilings by building a one-page reference table from the current rating system documentation.

  • Explain in writing how the integrative process credit differs from conventional design coordination in an existing building context.

  • List the eligibility requirements for the LEED AP O+M credential, including the prerequisite LEED Green Associate status and any project participation requirement.

  • Draft a personal eligibility checklist confirming which requirements you already meet and which need action before scheduling.

  • Define the difference between certification and recertification cycles in O+M and note the performance period length each requires.

Your checkpoint

A one-page credit map plus a completed personal eligibility checklist with gaps flagged.

Week 2

Energy and atmosphere performance: benchmarking, commissioning, audits and metering

  • Calculate weather-normalized energy use intensity from a sample 12-month utility dataset and state the normalization method used.

  • Compare ENERGY STAR Portfolio Manager benchmarking output against a stated baseline and interpret the score change.

  • Sequence the steps of an ASHRAE Level I, II, and III audit and identify which level supports which credit or prerequisite need.

  • Identify where permanent metering is required versus where aggregate utility data is acceptable for energy performance tracking.

  • Diagnose three common causes of a failing energy prerequisite and write the corrective action for each.

Your checkpoint

A worked energy performance worksheet: EUI calculation, benchmark comparison, and audit-level recommendation with justification.

Week 3

Energy and atmosphere performance: benchmarking, commissioning, audits and metering & Project and performance documentation: Arc platform, performance periods, prerequisites and recertification

  • Outline the commissioning process for an existing building, naming the roles of owner, commissioning authority, and contractor.

  • Distinguish ongoing commissioning from retrocommissioning and state when each applies.

  • Describe how Arc is used to upload, score, and verify performance data across the five performance categories.

  • Draft a 12-month performance period timeline showing data collection, upload, review, and score-freeze points.

  • Explain how prerequisite compliance is demonstrated differently from credit achievement in Arc.

Your checkpoint

A performance period calendar plus a one-page Arc data workflow diagram covering all five categories.

Week 4

Water efficiency performance and metering & Materials and resources: purchasing, waste and ongoing consumables

  • Compute water use intensity from fixture flow rates, flush volumes, and occupancy assumptions for a sample building.

  • Identify which water subsystems require separate metering and justify each choice.

  • Build an indoor potable water use reduction calculation comparing a baseline fixture set to a proposed set.

  • Classify ongoing consumables, durable goods, and facility maintenance products and state the purchasing criteria that apply to each.

  • Design a waste stream tracking sheet that separates diverted, landfilled, and incinerated tonnage and computes a diversion rate.

Your checkpoint

A combined water and waste calculator spreadsheet that outputs WUI, percent water reduction, and diversion rate from entered data.

Week 5

Indoor environmental quality: IAQ management, green cleaning and occupant comfort & Materials and resources: purchasing, waste and ongoing consumables

  • Draft an indoor air quality management plan for an occupied building covering flush-out, testing, and occupant notification.

  • Compare green cleaning product certification criteria and write a purchasing specification clause that satisfies them.

  • List the components of a green cleaning policy, including equipment, chemicals, and custodial training.

  • Identify occupant comfort survey methods and explain how survey results feed into corrective action.

  • Trace how a purchasing policy change propagates into the materials and resources credit documentation.

Your checkpoint

A one-page green cleaning policy outline plus an IAQ management plan checklist with responsible parties assigned.

Week 6

Site management, transportation performance and light pollution & LEED v4.1/v5 O+M rating system fundamentals (integrative process, location and transportation, sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, innovation, regional priority)

  • Calculate a transportation performance metric from survey data on commuting mode share and distance.

  • Explain how alternative transportation credits are documented through occupant surveys and site amenities.

  • Assess a site management plan for compliance with integrated pest management, erosion control, and fertilizer reduction criteria.

  • Evaluate exterior lighting against light pollution reduction criteria using luminaire uplight and light trespass limits.

  • Connect the location and transportation category to the surrounding density and diverse use criteria in the rating system.

Your checkpoint

A transportation and site performance report for a hypothetical building with mode share, site plan gaps, and lighting compliance verdict.

Week 7

Project and performance documentation: Arc platform, performance periods, prerequisites and recertification & Credential process and standards: eligibility, exam administration, and LEED professional conduct

  • Assemble a full recertification evidence package checklist naming each document type required per category.

  • Explain the exam administration rules: format, question count, time allotted, and scoring and retake policy as published by the credentialing body.

  • Summarize the professional conduct expectations for a LEED AP, including accurate claims about credential status and confidentiality of exam content.

  • Write a short statement distinguishing what an unaffiliated study resource can and cannot claim about the credential.

  • Rehearse recertification timing so that no performance period lapses between cycles.

Your checkpoint

A recertification document checklist plus a written summary of exam administration and conduct rules in your own words.

Week 8

LEED v4.1/v5 O+M rating system fundamentals (integrative process, location and transportation, sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, innovation, regional priority) & Project and performance documentation: Arc platform, performance periods, prerequisites and recertification & Energy and atmosphere performance: benchmarking, commissioning, audits and metering & Water efficiency performance and metering & Materials and resources: purchasing, waste and ongoing consumables & Indoor environmental quality: IAQ management, green cleaning and occupant comfort & Site management, transportation performance and light pollution & Credential process and standards: eligibility, exam administration, and LEED professional conduct

  • Take two full-length timed practice sets and record per-domain accuracy.

  • Re-teach your three weakest domains from your own notes without consulting source material.

  • Recompute one energy, one water, and one waste calculation from scratch to confirm method retention.

  • Review every prerequisite across all categories and confirm you can state its compliance path from memory.

Your checkpoint

A scored practice log with per-domain accuracy plus a one-page prerequisite recall sheet.

Milestones

Week 2: You can compute EUI and a benchmark comparison unaided and explain which audit level applies to a given scenario.

Week 4: Your combined calculator returns correct WUI, water reduction percentage, and diversion rate on a fresh dataset.

Week 6: You can defend a transportation mode share figure and a light pollution verdict without notes.

Week 8: Practice set accuracy is at or above 80 percent overall with no domain below 65 percent.
