BPI HEP Energy Auditor study guide
BPI HEP Energy Auditor · Work through your exam, one topic at a time.
The BPI Energy Auditor credential is one of the certifications listed by the Building Performance Institute, a non-profit that describes its mission as advancing the home performance industry through nationally recognized standards and credentials intended to ensure homes are comfortable, healthy, safe, durable, and energy efficient. BPI presents itself as "the symbol of excellence for home performance professionals" and organizes its offerings into certificates, certifications, standards, test centers, proctors, and GoldStar contractors. The Energy Auditor sits alongside related credentials such as Building Analyst Technician, Building Analyst Professional, Quality Control Inspector, and Multifamily Building Analyst, which suggests a career ladder running from diagnostic fieldwork toward whole-house analysis and quality assurance. Candidates are typically people who inspect homes, collect building and mechanical data, run diagnostic tests, model energy use, and translate findings into prioritized improvement scopes for homeowners and program staff. The BPI HEP Energy Auditor study guide has 4 sections and about 1,146 words.
01Building Science and Home Performance Fundamentals
Every audit question rests on the idea that a house is a coupled system: the building enclosure, the mechanical systems, and the occupants interact. Heat, air, and moisture move together.
323 words, about 2 min02Audit Data Collection and Diagnostic Testing
A complete audit gathers: building dimensions and geometry, insulation levels and types, window and door specs, HVAC equipment nameplate data, duct layout, and occupant comfort complaints. Record baseline conditions (thermostat setpoints, weather) so results are interpretable.
291 words, about 1 min03Energy Modeling, Analysis, and Prioritizing Improvements
Understand that energy models are calibrated approximations. Know the inputs that dominate results: envelope areas and R-values, infiltration (CFM50-derived), HVAC efficiency (AFUE, SEER, HSPF), and internal gains.
264 words, about 1 min04Work Scope Development, Standards, and Client Communication
A work scope is a contract: it must specify what, where, how much, and by whom . Include quantities, R-values, air-sealing locations, equipment model and efficiency, and verification tests (e.g., post-blower-door target).
