The load created by moisture in the air, including from outside air infiltration and that from indoor sources such as occupants, plants, cooking, showering, etc.

To allow or augment the natural movement of cooler air from exterior, shaded areas of a building through or around a building.

These fluids can be either water or steam trapped in fractured or porous rocks; they are found from several hundred feet to several miles below the Earth's surface. The temperatures vary from about 90 F to 680 F (32 C to 360 C) but roughly 2/3 range in te ...

Power generation equipment or system capacity to meet peak power demands.

A characteristic applied to domestic water heaters that is the amount of gallons raised 100 degrees Fahrenheit per hour (or minute) under a specified thermal efficiency.

This device can automatically turn the heater off at night and on in the morning.

A construction material made by compressing earth in a form; used traditionally in many areas of the world and widely throughout North Africa and the Middle East.

The labels placed on appliances to enable consumers to compare appliance energy efficiency and energy consumption under specified test conditions as required by the Federal Trade Commission.

A type of incandescent lamp that contains a halogen gas in the bulb, which reduces the filament evaporation rate increasing the lamp life. The high operating temperature and need for special fixtures limits their use to commercial applications and for use ...

The conversion of heat into electricity by the use of thermocouples.

A ratio of the work or useful energy output of a system versus the amount of work or energy inputted into the system as determined by using the same energy equivalents for energy in and out. Is used as a measure of the steady state performance or energy e ...

The process of converting materials that are no longer useful as designed or intended into a new product.

The process of moving existing loads to off-peak periods.

Caulking and weatherstripping to reduce air infiltration and exfiltration into/out of a building.

Costs that are repetitive and occur when an organization produces similar goods or services on a continuing basis.

An electrical generator that runs at a constant speed and draws its excitation from a power source external or independent of the load or transmission network it is supplying.
