Energy Management Basics

SKU: RVI-11490Duration: 20 Minutes

Buildings account for 76% of all the electricity consumed in the U.S. With that much energy being consumed; there are certainly some opportunities for improvements in operational efficiency. In managing the energy consumption of a building there are two goals, one is to provide and maintain the comfort of the occupants, and one is to minimize the amount of energy, and therefore money, consumed in the process. This interactive online course will cover some of the terminology and skills involved in basic building energy management.

The easiest way to save money when managing energy consumption is to turn off energy consuming items when they are not needed.

Electricity is measured using primary electric meters and submeters that monitor the usage downstream of the primary meter.

Consumption can be reduced by employing timeclocks that automatically turn electrical devices off and on throughout a day.

Key Questions

The following key questions are answered in this module:

How is electric power measured?
Power delivered by electricity is measured in watts.

What is energy demand?
Demand is a measure of use at one point in time, and it is measured in kilowatts.

What is energy consumption?
Energy consumption is the accumulation of demand over some time, determined by multiplying the demand by a period, expressed as kilowatt-hours.

What is a BTU?
A BTU is the amount of energy required to increase the temperature of one pound of water by one degree Fahrenheit.

What is a "therm"?
A therm is equal to 100,000 BTUs, or British Thermal Units.

Sample Video Transcript

Below is a transcript of the video sample provided for this module:

In the example shown, the dials from left to right should be read as 3, 6, 3. In the fourth dial from the left the indicator is pointing directly at the 7, but looking in the next dial to the right, the indicator has not entirely gone past the 0 point, so the last two dials should be read as 6 and 9, giving a total reading of 36,369 kWh. Some meters do not have dials for the least significant digits of the reading. These will be marked with "MULT x10" or "MULT x100" indicating that the numbers collected should be multiplied by 10 or 100 for the final reading. In this example, the reading would be 93,950 kWh. The second type of meter is all digital, and the kilowatt hours are presented as a value that can be read directly.
