A substance(s) or pollutant emitted as a result of a process.

The approximate energy producing capacity of a power plant, under specified conditions, usually during periods of highest load.

A material used to seal gaps around windows and exterior doors.

The storage of heat energy during utility off-peak times at night, for use during the next day without incurring daytime peak electric rates.

These brines are hot (300 F to 400 F) (149 C to 204 C) pressurized waters that contain dissolved methane and lie at depths of 10,000 ft (3048 m) to more than 20,000 ft (6096 m) below the earth's surface. The best known geopressured reservoirs lie along th ...

Air brought into a building from outside to replace exhaust air.

The visible portion of the electromagnetic spectrum with wavelengths from 0.4 to 0.76 microns

Standardized weights or volumes for heating fuels.

A device for converting a solid fuel to a gaseous fuel.

The natural, convective movement of air or water due to differences in temperature. In solar passive design a thermosyphon collector can be constructed and attached to a house to deliver heat to the home by the continuous pattern of the convective loop (o ...

A column of burning combustion gases that are so hot and strong that the heat is lost up the chimney before it can be transferred to the house. A draft brings air to the fire to help keep it burning.

A large number of thermocouples connected in series.

A diagram that indicates the average percentage of time that the wind blows from different directions, on a monthly or annual basis.

The physically connected generation, transmission, and distribution facilities and components operated as a unit.

A unit of rate of water evaporation equal to the evaporation per hour of 34.5 pounds of water at a temperature of 212 degrees Fahrenheit into steam at 212 degrees F.

A device mounted in the vent connector that closes the vent when the heating unit is not firing. This traps heat inside the heating system and house rather than letting it draft up and out the vent system.

Those elements of building used to control the interior climate.

The unit price and quantity to which it applies as specified in a rate schedule or contract.

Any light source designed specifically to direct light a task or work performed by a person or machine.
