Note: Power factor (0.85) not needed for kW calculation — only for kVA. Term: Chilled Water Reset Card 4 – Back A: A control strategy that increases chilled water supply temperature as cooling load decreases (e.g., from 44°F to 50°F at part load).
If NPV > 0 → accept project (earns more than hurdle rate). If NPV < 0 → reject.
The effective annual return from the project’s cash flows. Compare to company’s hurdle rate (e.g., 12%). If IRR > hurdle rate → accept. Note: Power factor (0
Note: May produce multiple values for non-conventional cash flows. Which ASHRAE Standard defines energy baseline and modeling for commercial buildings? Card 12 – Back A: ASHRAE Standard 90.1 (Energy Standard for Buildings Except Low-Rise Residential) — particularly Appendix G for Performance Rating Method.
Isolated retrofit, stipulated assumption for unmeasured factors. Option B: All parameters measured. Card 8 – Front True or False: Power factor correction capacitors reduce kW demand charges. Card 8 – Back A: False. Capacitors reduce kvar , thus lowering kVA (apparent power), which may reduce kVA demand charges , but not kW demand. kW is real power, unchanged by capacitors. If NPV < 0 → reject
= (200 × 0.75 × 0.746) / 0.90 = (111.9) / 0.90 =
Note: For CEM exam, know how to compare NPV of two mutually exclusive projects. What is the primary purpose of a Measurement & Verification (M&V) Plan (IPMVP Option A or B)? Card 7 – Back A: To quantify actual energy savings from an ECM (Energy Conservation Measure) by comparing measured post-retrofit energy use to a baseline adjusted for relevant variables (weather, occupancy, production). If IRR > hurdle rate → accept

Savings = $2,000,000 × 0.08 = $160,000 ROI = ($160,000 / $250,000) × 100 =
