If NPV > 0 → accept project (earns more than hurdle rate). If NPV < 0 → reject. Term: Chilled Water Reset Card 4 – Back

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). Card 9 – Back A: Heating Energy (MMBtu)

Exception: Reduced I²R losses in cables can slightly lower kW — usually negligible. Define: Degree-Day method for estimating heating energy. Card 9 – Back A: Heating Energy (MMBtu) = (HDD × UA × 24 hr/day) / (System Efficiency × 10^6)

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.

Each card features a question, key term, formula, or scenario on the front, and a detailed, exam-relevant answer on the back.
