  1. Which metric is most commonly used to benchmark a building's energy performance against similar facilities in the US?

    Answer: Energy Use Intensity (EUI)

    Energy Use Intensity (EUI) measures energy consumed per square foot per year and is the standard ENERGY STAR benchmarking metric.

  2. A facility manager wants to reduce standby power losses. Which strategy is MOST effective for office equipment?

    Answer: Installing smart power strips with occupancy sensing

    Smart power strips automatically cut power to devices in standby mode, directly eliminating phantom loads.

  3. Under the ISO 50001 framework, what is the primary output of an Energy Review?

    Answer: Identification of significant energy uses and improvement opportunities

    ISO 50001 requires an Energy Review to identify significant energy uses (SEUs) and opportunities for energy performance improvement.

  4. Which type of insulation has the highest R-value per inch, making it ideal for space-constrained retrofits?

    Answer: Closed-cell spray polyurethane foam (SPF)

    Closed-cell SPF provides approximately R-6 to R-7 per inch, the highest of common insulation types.

  5. A manufacturing plant switches from a compressed air pressure of 110 psi to 90 psi system-wide. What is the approximate energy savings?

    Answer: 5% per 10 psi reduction

    A commonly cited rule of thumb is that reducing compressed air pressure by 10 psi saves approximately 5% of compressor energy.

  6. What does the term 'demand response' refer to in the context of utility programs?

    Answer: Reducing or shifting electricity load during peak grid stress periods at utility request

    Demand response programs incentivize customers to reduce or shift electrical loads during peak demand or high-price periods.

  7. Which lighting control strategy yields the greatest energy savings in a daylit perimeter office zone?

    Answer: Continuous daylight dimming with occupancy sensing

    Combining continuous daylight dimming with occupancy sensing captures both daylight harvesting and unoccupied-period savings.
