A nationally recognized energy rating program that gives builders, mortgage lenders, secondary lending markets, homeowners, sellers, and buyers a precise evaluation of energy losing deficiency's in homes. Builders can use this system to gauge the energy q ...

The material through which electricity is transmitted, such as an electrical wire, or transmission or distribution line.

The value or purchasing power of a dollar that has not been reduced to a common basis of constant purchasing power, but instead reflects anticipated future inflation; when used in computations the assumed inflation rate must be stated.

A solar collector in which the absorber is contained in a sealed glass tube, thereby providing for relatively high temperature heat gain.

Transmit high-voltage electricity from the transformer to the electric distribution system.

A smaller version of standard fluorescent lamps which can directly replace standard incandescent lights. These lights consist of a gas filled tube, and a magnetic or electronic ballast.

To condition/cool air by dessication.

A smokestack or flue for exhausting the products of combustion from a combustion appliance.

Consists of businesses that are not engaged in transportation or manufacturing or other types of industrial activities. Standard Industrial Classification (SIC) codes for commercial establishments are 50 through 87, 89, and 91 through 97.

Technologies that pertain to the generation of electricity.

Standardized codes used to classify businesses by type of activity they engage in.

The average amount of solar radiation that reaches the earth's upper atmosphere on a surface perpendicular to the sun's rays; equal to 1353 Watts per square meter or 492 Btu per square foot.

The physical process by which a liquid or solid is transformed into the gaseous state. For this process a mechanical device uses the outside air's heat to evaporate water that is held by pads inside the cooler. The heat is drawn out of the air through thi ...

A solar collector that uses reflective surfaces to concentrate sunlight onto a small area, where it is absorbed and converted to heat or, in the case of solar photovoltaic (PV) devices, into electricity. Concentrators can increase the power flux of sunlig ...

A small groove scribed into the surface of a solar photovoltaic cell which is filled with metal for contacts.

The lowest wind speed at which a wind turbine begins producing useable power.

That part of an electricity bill that is based on the amount of electrical energy consumed or supplied.

Materials that prevent or slow down the movement of heat.

The local climate of specific place or habitat, as influenced by landscape features.

The sum of sensible heat and latent heat in a substance above a base temperature, typically 32 degrees Fahrenheit.
