Which two components are included in the Peak Demand calculation?

The correct answer pertains to the measurement of energy consumption during periods of peak demand, which is essential for understanding a building’s energy use profile. Peak Demand is often analyzed based on actual usage patterns during the hours when demand is highest.

Baseload represents the minimum level of demand on an electrical grid over a span of time, while On-Peak Demand refers to the maximum expected demand during specific high-usage periods. These components are vital for calculating Peak Demand because they provide insight into both consistent energy use and the spikes in demand that occur during peak hours.

Heating and Cooling Usage is important as it directly reflects the energy consumption for heating and cooling, which represents significant contributors to a building's overall energy demand during peak times. This aligns with how energy utilities manage capacity and load management strategies.

In contrast, Heating Efficiency and Cooling Efficiency relate to how effectively heating and cooling systems operate but do not encompass the broader calculation of Peak Demand. Similarly, Time of Use primarily addresses pricing based on the time of energy consumption rather than directly measuring demand levels. Thus, the focus on Heating and Cooling Usage for Peak Demand calculation makes that choice valid and relevant.
