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.

Boxed set of 300+ double-sided flashcards, plus quick-reference tabs and online access code. System Introduction (Printed on inside cover of card box) Welcome to the most effective rapid-review system for the CEM Exam, administered by the Association of Energy Engineers (AEE). This flashcard system is designed to condense the 5 key CEM exam bodies of knowledge— Energy Accounting & Economics, Energy Audits & Instrumentation, Electrical Systems, HVAC & Thermal Systems, and Building Envelope & Lighting —into high-yield, portable study cards.

Also relevant for CEM: ASHRAE/IESNA 100 (Existing Buildings), ASHRAE 62.1 (Ventilation). Practice Question: A plant has annual energy cost $2,000,000. A project saves 8% with a $250,000 cost. What is the ROI first year? Card 13 – Back A: ROI = (Annual Savings / Project Cost) × 100

= (200 × 0.75 × 0.746) / 0.90 = (111.9) / 0.90 =

The effective annual return from the project’s cash flows. Compare to company’s hurdle rate (e.g., 12%). If IRR > hurdle rate → accept.

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.

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