EMP Sustainable Practices & Conservation 2

Question 1

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

Accepted Answer

Energy Use Intensity (EUI)

Answer

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

Question 2

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

Accepted Answer

Installing smart power strips with occupancy sensing

Answer

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

Question 3

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

Accepted Answer

Identification of significant energy uses and improvement opportunities

Answer

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

Question 4

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

Accepted Answer

Closed-cell spray polyurethane foam (SPF)

Answer

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

Question 5

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

Accepted Answer

5% per 10 psi reduction

Answer

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