222+ Free AEE Certified Energy Auditor Practice Questions

Developing an Energy Audit Strategy & Plan

Plan the audit, define procedures, project team, audit level, pre-audit tasks, instrumentation, O&M interviews, report requirements, follow-up, ISO 50001 support, ASHRAE 211, ISO 50002, and applicable codes or industry requirements.

Energy Use Analysis

Define required usage information, review rates, establish utility cost and energy baselines, apply relevant variables and regression, analyze graphs, benchmark, calculate EUI and ECI, estimate load factor, break down end uses, use balance-point temperature, and analyze fleet information.

Data Collection & Analysis

Define and collect pre-site and on-site data, select instrumentation, determine EEMs for evaluation, account for interactive effects, and understand ordinary least squares regression modeling.

Economic Analysis

Review decision criteria, cost O&M and capital measures, calculate payback, NPV, IRR, LCC, FCF, SIR, BCR, annual value, replacement chain and equivalent annual annuity, analyze transport options, run sensitivity and scenario analysis, and present financial results.

Lighting Systems

Evaluate efficacy, lumen depreciation, fixture and lamp types, replacement options, lighting controls, lighting power density, illumination levels, daylight harvesting, lighting EEMs, O&M, and savings.

Heating, Ventilation & Air Conditioning Systems

Audit HVAC, heating, and ventilation systems, including equipment types, controls, efficiencies, filters, chillers, boilers, furnaces, distribution, steam traps, ventilation requirements, EEMs, O&M, and savings.

Domestic Hot Water Systems

Audit DHW system type, efficiency, temperature set points, circulation, EEMs, O&M, energy savings, water use, irrigation, water efficiency measures, and water savings.

Motors & Drives & Compressed Air Systems

Understand electrical fundamentals, motor sizing, motor and drive characteristics, efficiencies, VFD savings, compressed-air supply, controls, treatment, distribution, storage, demand, leaks, inappropriate uses, artificial demand, EEMs, O&M, and savings.

Building Envelope

Determine R-values and U-values, evaluate walls, roofs, windows, glass alternatives, infiltration, thermal mass, envelope EEMs, O&M, energy modeling methods, and savings.

BAS, PAS and EMCS

Understand energy-saving controls, identify EMS issues, determine needed points, evaluate operator use, read trends, handle sensor accuracy problems, identify EEMs, evaluate O&M, and calculate savings.

Alternative Generation & Storage

Screen alternative generation, renewables, cogeneration, thermal storage, electrical storage, demand response, integration impacts, costs, sites, and incentives.

Transport

Evaluate transport modes, vehicles, fuel costs, driver operation, maintenance, logistics, routes, fleets, transport energy performance indicators, benchmarking, modeling, vehicle improvements, monitoring, and driver performance.
