Langley, английский
- A unit of energy per unit area, equal to 1 gramcalorie/cm² and commonly employed in radiation measurement.
- The unit of solar energy relating to the amount which reaches a specific area of the earth`s surface. in general, more "langleys" reach the surface of the earth at the equator than at the poles.

Irradiance, английский
- The density of the luminous flux which is incident on a surface.
- Интенсивность излучения
- The direct, diffuse, and reflected solar radiation that strikes a surface. usually expressed in kilowatts per square meter. irradiance multiplied by time equals insolation.
- The direct, diffuse, and reflected solar radiation that strikes a surface. usually
- Power of electromagnetic radiant energy incident on or radiated from the surface of a given unit area. compare radiance.
- Radiant power falling upon a known surface area at a given angle. compare radiance. see also radiometer. ishiharatm plates: trade name for a kind of pseudoisochromatic plates, used for color differentiation vision testing.
- Total radiant power, in watts per square meter (w/m2), falling upon a known surface area at a given angle.
- Total radiant power, in watts per square meter (w/m2), falling on a known surface area at a given angle. compare radiance. see also radiometer. irradiance, effective: measure of spectrally weighted radiant power in watts per meter-squared, as determined with a sensor whose responsivity replicates some desired action spectrum. compare irradiance; irradiance, spectral. irradiance, spectral: measure of energy emitted by a radiation source as function of wavelength. units of spectral irradiance are watts per square meter per nanometer (w·m–2·nm–1) and are often plotted versus wavelength. see also spectral power distribution. ishihara plate: trade name for a kind of pseudoisochromatic plate used for color differentiation vision testing.
- Radiant power falling upon a known surface area at a given angle. in nondestructive testing, the unit for irradiance of a uv-a source is microwatt per centimeter squared (?w·cm–2) and maximum irradiance occurs when the source and surface are perpendicular.
- Radiometer. j
Centimeter, английский
- Сантиметр
- In the metric system, a measure of length equal to a hundredth part of a meter, or 0.3937+ in.; abbreviated cm; an inch equals 2.54 cm. central air-conditioning system an airconditioning system in which the air is treated by equipment at one or more central locations outside the spaces served, and conveyed to and from these spaces by means of fans and pumps through ducts and pipes. central air-handling unit an air-handling unit in which treated air is distributed to a number of spaces by means of ductwork.

Renewable portfolio standard (rps), английский
A market based mechanism devised by nancy rader and richard norgaard for the american wind energy association in 1996. it obliges supply companies or consumers to purchase a specific amount of electricity from renewable energy sources. the key goal of such a mechanism is to minimise the costs of increasing renewable energy capacity through the stimulation of competition to fulfil obligations. the rps mechanism is also known as a quota or obligation mechanism. examples of the rps include the renewables obligation in the uk or the mandatory renewable energy target in australia). the market may be operated through the creation and trading of certificates (renewable energy certificates). reeep / sustainable energy regulation network – august 2004 - revised september 2010 9 regulatory asset base (rab) (also regulatory asset value - rav): the capital value of the assets used by regulators in setting prices or price limits for utility companies. a basic formula in utility rate-setting is: required revenue = operating costs + depreciation + return on capital. that is to say, utility charges should be designed to recover no more than reasonable operating costs (including taxes), plus capital charges that provide investors with a competitive return equal to what they would have earned on other investments of equivalent risk. capital charges include both a return of investment (also known as depreciation) and a return on investment (known as profit). both depreciation and return on capital require an approach to asset valuation, i.e., the determination of the regulatory asset base.
Base load generating plants, английский
Typically coal or nuclear generating units that are committed and dispatched at constant or near-constant levels with minimum cycling. they are often the sources of lowest-cost of energy when run at very high capacity factors.
