What This Cheat Sheet Covers (and What It Doesn't)
This page condenses the published Multifamily Building Analyst (MFBA) knowledge list into a single reference you can scan the week before your exam and revisit during practice sessions. It is organized the way BPI organizes the credential: five knowledge areas, each containing numbered topics that candidates are expected to understand. If you want a slower, step-by-step plan, the MFBA Study Guide 2026: How to Pass on Your First Attempt walks through preparation in more depth. For a deeper treatment of each area, see MFBA Exam Domains 2026: Complete Guide to All 5 Content Areas.
Also keep in mind what this sheet deliberately omits. It does not quote a passing score, pass rate, fee, or exam date, because those details belong in dedicated references. For official mechanics, check the BPI certification page directly, then see MFBA Passing Score 2026: Exactly What You Need to Pass, MFBA Certification Cost 2026: Complete Pricing Breakdown, and MFBA Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

Building Science: Must-Know Concepts
The first area is the conceptual foundation. It is where multifamily-specific physics shows up, and candidates coming from single-family backgrounds often underestimate it.
Domain 1: Building Science
Expect to explain mechanisms, not just recite terms. The list covers heat transfer, moisture transport, airflow behavior, ventilation design, and combustion.
- Heat transfer and moisture transport: basic mechanisms for both (1.1.1, 1.1.2).
- Multifamily airflow characteristics: single zone, parallel floor, and compartmentalization concepts (1.1.3).
- Ventilation strategies: identify typical multifamily ventilation system designs and where each applies (1.1.4).
- Stack effect in ventilation stacks: how stack effect and airflows interact (1.1.5).
- Elevator air leakage: a distinctly multifamily issue (1.1.6).
- Effective R-value and the psychrometric chart: define the first, demonstrate use of the second (1.1.7, 1.1.8).
- IAQ pollutant transport: how contaminants move through a building (1.1.9).
Combustion, Heat Recovery, and Loads
Basic combustion science and combustion technologies (1.1.10, 1.1.11) set up the combustion testing and safety material that appears later. Heat recovery appears twice: for ventilation systems and for domestic hot water systems (1.1.12, 1.1.13). Know the principle for each, since they solve different problems.
The quantitative items to be comfortable with are calculating heating and cooling degree days (1.1.17), knowing the heat content of typical fuels (1.1.18), and defining sensible and latent loads (1.1.19). The last pairs naturally with the psychrometric chart: sensible changes temperature, latent changes moisture content.
Lighting and Appliance Interactions
Three less obvious items live here. You should identify correct lumen requirements for different areas of a building (1.1.14), associate lighting and appliance retrofits with internal gains and heating and cooling loads (1.1.15), and know proper de-manufacturing and disposal procedures for appliances and lighting components (1.1.16). The internal-gains link is a classic trap: a more efficient light or appliance lowers electric use but can raise heating load and lower cooling load. Finally, 1.1.20 asks you to understand how efficiency measures interact and how that affects predicted savings, which is the conceptual root of why savings from individual measures rarely add up cleanly.
Auditing Skills: Communication, Scoping, and Reports
This is the largest area on the published list, and it is the one that most clearly distinguishes an analyst from a technician. It rewards candidates who have actually run an audit in an occupied building.
Domain 2: Auditing Skills
Think of this area in four clusters: people, data, measures, and the report.
- People: identify the building's decision-maker (1.2.5) and who holds the data you need (1.2.6); apply the LAYER technique, which stands for Listen, Acknowledge, Explore, Respond (1.2.9); tailor communication for residents, staff, and management (1.2.10); respect cultural context and confidentiality when interviewing and inspecting units (1.2.11, 1.2.12).
- Data: list pre-interview data collection items (1.2.7); obtain the existing maintenance and capital replacement schedules (1.2.13); read mechanical operating manuals (1.2.17); build a full mechanical equipment schedule and a schedule of electrical fixtures and appliances (1.2.38, 1.2.39).
- Measures: estimate installed costs and labor (1.2.22, 1.2.23); predict results (1.2.24); prioritize measures unique to multifamily buildings (1.2.25); evaluate cost-effectiveness, demand reduction, and fuel switching (1.2.26 to 1.2.28).
- Report: develop a work scope and project report (1.2.30) and demonstrate a complete report with existing conditions, proposed scope, savings estimates, and job cost estimates (1.2.52).
Metering and Technology Evaluation
Two threads are easy to overlook. First, metering: identify typical metering configurations (1.2.47) and determine how the configuration changes your recommendations (1.2.48). Who pays the bills shapes which measures make sense and who benefits, a theme that returns in the analysis area. Second, the technology evaluations: motor types and replacement schedules (1.2.37, 1.2.40, 1.2.41), lighting retrofits across living units, common areas, and exterior (1.2.43), lighting controls (1.2.44), daylighting (1.2.45), appliance replacement (1.2.46), electrical use indices (1.2.49), demand reduction (1.2.50), and renewable energy retrofits (1.2.51).
Key Takeaway
Know when to call for help. Item 1.2.19 expects an analyst to recognize when outside expertise is required to complete the inspection, analysis, or report. On scenario questions, the best answer is sometimes to bring in a specialist rather than to push ahead.
Inspection and Diagnostics: Field Procedures
The third area is the hands-on, field-facing material: choosing and using tools, then diagnosing what you find.
Domain 3: Inspection and Diagnostic Skills
Questions here tend to test whether you know what to measure, with what, and what the result means.
- Tools: select and properly use equipment for the audit (1.3.1, 1.3.2); measure light levels with a lumen meter (1.3.31).
- Moisture and blueprints: identify and diagnose moisture issues (1.3.3); read blueprints and use them to locate likely airflow paths (1.3.4, 1.3.5).
- Ventilation: inspect condition and effectiveness, and measure flow rates of mechanical ventilation (1.3.7, 1.3.8).
- Air leakage: locate leakage paths and bypasses contributing to stack effect and uncontrolled infiltration or exfiltration; locate airflow communication paths between units (1.3.10, 1.3.11).
- Elevators: relate elevator location and design to airflow performance, and evaluate when shaft ventilation may be sealed (1.3.12, 1.3.13).
Envelope, Windows, and Thermal Bridges
You should verify insulation type and condition (1.3.9), inspect windows and doors for fit, operation, and performance (1.3.14), estimate window U-value (1.3.15), evaluate effective R-value of envelope components (1.3.16), identify thermal bridges (1.3.17), and determine retrofit options for thermal envelope improvements (1.3.18). Remember the relationship: U-value is the inverse of R-value, and effective R-value accounts for the whole assembly, including bridging, not just the insulation layer.
Mechanical, Combustion, and Water Systems
Mechanical content spans hydronic, steam, and forced-air heating and cooling components and their functions (1.3.19), visual inspection of mechanical equipment (1.3.6), heating plant operation (1.3.22), controls and their impact on performance (1.3.23), and distribution system condition (1.3.24). Combustion efficiency testing and determining whether equipment operates within acceptable ranges are 1.3.20 and 1.3.21.
Two items connect to safety and to measure screening. Identify fire suppression systems and determine whether efficiency measures would compromise them (1.3.25, 1.3.26). On the water side, identify circulation systems and potential savings (1.3.27), understand pump sizing criteria (1.3.28), identify point-of-use water-saving measures (1.3.29), and measure domestic hot water temperature at the point of use (1.3.30).
Installation and Analysis: Data, Models, and Economics
The fourth area is where the analyst turns utility data and building observations into defensible savings estimates and economic justification.
Domain 4: Installation and Analysis Skills
This area has three layers: consumption analysis, modeling, and economics.
- Consumption analysis: collect energy and water use data and graph monthly usage (1.4.1, 1.4.2); apply unit-by-unit, whole-building, and dual-fuel approaches (1.4.3 to 1.4.5); calculate heating, cooling, and base loads (1.4.6); understand weather-dependent results (1.4.7).
- Baselines and indices: establish energy use indices and fuel and energy load baselines (1.4.13, 1.4.15); attribute consumption to end uses (1.4.16); establish proper fuel unit costs (1.4.17); determine who pays for utilities (1.4.14).
- Gaps and rates: know what to do when consumption data is missing or incomplete (1.4.10); understand utility rate structures (1.4.11).
Modeling and Calibration
Know the difference between bin, degree-day, and hourly analysis (1.4.19). Be able to calculate heat loss, heat gain, and heating and cooling loads (1.4.18, 1.4.20), prepare and input data accurately (1.4.21), and calibrate the model so results are realistic (1.4.22). The exam logic is consistent: a model is only credible if you justify it against actual consumption (1.4.26) and compare model output to utility data (1.4.9) and to observed conditions in the building (1.4.8). Also know typical modeling algorithms, how models work and how to troubleshoot them, and which software tools suit which applications (1.4.23 to 1.4.25).
Economics
Economic evaluation covers estimated savings for recommended measures (1.4.28), life cycle analysis (1.4.29), non-energy savings or costs and non-economic benefits (1.4.30, 1.4.31), and cost-effectiveness criteria such as BLCC, ROI, and SIR, including when to use each (1.4.32). Add financing options (1.4.33), the economic effect of demand rates (1.4.34), inflation and discount factors (1.4.35), and documentation of cost estimates (1.4.36). Item 1.4.27 asks you to compare the cost of predicted energy savings against the actual highest unit usage, a sanity check that keeps projections honest.
Health and Safety: Combustion, IAQ, and Contaminants
The fifth area is the shortest on the published list at 16 topics, but it carries real consequences in the field. Treat it as non-negotiable.
Domain 5: Health and Safety
The thread running through this area is that energy measures must never create or worsen a hazard.
- Inspection and personal safety: visual health and safety inspection of units, common areas, and mechanical rooms (1.5.1); personal safety procedures (1.5.2); material safety data sheets (1.5.5); OSHA requirements related to the auditor's work (1.5.6).
- Combustion: identify all combustion sources in the building (1.5.3); combustion safety testing for large systems (1.5.14); evaluate combustion air supply (1.5.15); assess burner modulation and cycling (1.5.16); know CO detector requirements and applications (1.5.13).
- Contaminants: types, sources, and health effects for CO, mold, asbestos, and lead (1.5.7); building connections to pollutant sources such as garages and commercial areas (1.5.8).
- IAQ: recognize IAQ conditions including chemicals, moisture, and mold (1.5.9); assess problems and sources (1.5.10); relate observed IAQ to building conditions to find sources and mitigation strategies (1.5.11); identify contaminant transport paths (1.5.12).
- Measure impacts: identify and address health and safety issues that may be affected by energy saving measures (1.5.4).
Notice how this area ties back to the first. Building Science teaches pollutant transport and combustion science; Health and Safety asks you to apply them to a real building where, for example, tightening the envelope could change combustion air supply or spread a contaminant between units.
Quick-Reference Definitions and Calculations
| Term or Task | One-Line Reminder |
|---|---|
| Effective R-value | The thermal resistance of the whole assembly as built, including the effect of framing and bridging, not just the insulation rating. |
| Sensible vs. latent load | Sensible changes air temperature; latent changes moisture content. The psychrometric chart relates them. |
| Degree days | A weather-based measure used to relate heating or cooling energy use to outdoor temperature. |
| Stack effect | Buoyancy-driven airflow that is especially important in tall multifamily buildings and ventilation stacks. |
| Compartmentalization | Controlling airflow between units and zones, a core multifamily airflow concept. |
| LAYER | Listen, Acknowledge, Explore, Respond: the interview technique named in the knowledge list. |
| Unit-by-unit vs. whole-building analysis | Two views of consumption data; the metering configuration influences which is available. |
| BLCC, ROI, SIR | Cost-effectiveness criteria; know when each applies, not just what the letters mean. |
| Bin vs. degree-day vs. hourly | Three levels of analysis granularity for load calculation. |
Key Takeaway
When a question describes a measure, ask three things in order: what does it change physically, who benefits given the metering setup, and could it create a combustion, moisture, or IAQ problem? Those three filters map to Building Science, Auditing and Analysis, and Health and Safety.
Sequencing Your Review Around the Five Areas
Because the official list is unweighted, a balanced pass is safer than gambling on a favorite area. The sequence below orders areas by dependency: concepts first, then field skills, then analysis, then the reporting and safety layers that tie everything together. Adjust the pace to your own schedule. Section 1.1 and the first half of 1.3 usually reward short, repeated reviews, while 1.4 rewards working actual examples.
Building Science foundations
- Work through 1.1.1 to 1.1.9 with an eye on multifamily airflow, stack effect, and elevators.
- Practice reading a psychrometric chart and separating sensible from latent loads.
Inspection and diagnostics
- Pair each measurement in 1.3 with its tool and its meaning.
- Review envelope, thermal bridge, window U-value, and effective R-value items together.
Installation and analysis
- Practice consumption analysis, baselines, and calibration logic from 1.4.1 to 1.4.26.
- Drill the cost-effectiveness criteria and discounting concepts.
