Glossary

Joule (J)
The SI derived unit of energy, work, or amount of heat. One joule equals the energy transferred when applying a force of one newton through a distance of one meter.
BTU (British Thermal Unit)
A unit of heat energy defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. Commonly used in HVAC systems.
Energy
The capacity to do work or produce heat. Can be measured in various units including joules, BTU, calories, and kilowatt-hours.
