CMM Energy Management & Sustainability

Question 1

Which metric is most commonly used to measure a building's energy use intensity (EUI)?

Accepted Answer

BTU per square foot per year

Answer

Energy Use Intensity (EUI) is expressed as BTU (British Thermal Units) per square foot per year, allowing comparison across buildings of different sizes.

Question 2

What is the primary purpose of an energy audit in a commercial building?

Accepted Answer

To identify opportunities to reduce energy consumption and costs

Answer

An energy audit systematically identifies where and how a building uses energy in order to pinpoint opportunities for reducing consumption and lowering utility costs.

Question 3

Which ASHRAE energy audit level involves a detailed analysis of capital-intensive modifications with engineering-level calculations?

Accepted Answer

Level III

Answer

ASHRAE Level III audits (Investment Grade Audit) include detailed engineering analysis of high-capital modifications, providing the data needed to support major investment decisions.

Question 4

A building maintenance manager wants to reduce peak demand charges on the electricity bill. Which strategy is most effective?

Accepted Answer

Load shifting or demand response scheduling

Answer

Peak demand charges are based on the highest 15- or 30-minute interval of power draw; load shifting moves energy-intensive tasks to off-peak hours to reduce that peak.

Question 5

What does LEED stand for in the context of green building certification?

Accepted Answer

Leadership in Energy and Environmental Design

Answer

LEED (Leadership in Energy and Environmental Design) is a globally recognized green building rating system developed by the U.S. Green Building Council.
