Those gases, such as water vapor, carbon dioxide, tropospheric ozone, methane, and low level ozone that are transparent to solar radiation, but opaque to long wave radiation, and which contribute to the greenhouse effect.

A commonly used analysis for reporting fuel properties; may be on a dry (moisture free) basis, as "fired", or on an ash and moisture free basis. Fractions usually reported include: volatile matter, fixed carbon, moisture, ash, and heating value (higher he ...

Energy that is capable or available for doing work; the time rate at which work is performed, measured in horsepower, Watts, or Btu per hour. Electric power is the product of electric current and electromotive force.

A unit for the quantity of electricity transported in 1 second by a current of 1 ampere.

The damping of interior temperature fluctuations by massive construction.

A steady-state fermentation process.

A solar power station investigated by NASA that entailed a satellite in geosynchronous orbit that would consist of a very large array of solar photovoltaic modules that would convert solar generated electricity to microwaves and beam them to a fixed point ...

A law to protect consumers and investors. It placed geographic restrictions on mergers and limitations on diversification into non-utility lines of business and takeovers of electric and gas utilities, and also established regulated monopoly markets or se ...

The weight of water vapor, per unit weight of dry air.

A type of window glazing films used to block the infrared (heat) portion of the solar spectrum but admit a higher portion of visible light.

A type of insulation that is molded or expanded to produce coarse, closed cells containing air. The rigid cellular structure provides thermal and acoustical insulation, strength with low weight, and coverage with few heat loss paths. Often used to insulat ...

A type of high intensity discharge light that has the most lumens per watt of any light source.

A fuel gas with a heating value between 90 and 200 Btu per cubic foot.

Solar energy systems that collect or absorb solar energy for useful purposes. Can be used to generate high temperature heat (for electricity production and/or process heat), medium temperature heat (for process and space/water heating and electricity gene ...

A measure of light quality. The maximum CRI value of 100 is given to natural daylight and incandescent lighting. The closer a lamp's CRI rating is to 100, the better its ability to show true colors to the human eye.

An interior or exterior movable panel that operates on hinges or slides into place, used to protect windows or provide privacy.

The monochromatic irradiance of a surface per unit bandwidth at a particular wavelength, usually expressed in Watts per square meter-nanometer bandwidth.

Thermal energy that is used in agricultural and industrial operations.

The percentage of a building's seasonal energy requirements that can be met by a solar energy device(s) or system(s).

That amount of cooling energy to be supplied (or heat and humidity removed) based on the sensible and latent loads.
