Site planning that accounts for natural solar heating and cooling processes and their relationship to building shape, orientation, and siting.

The process of characterizing the wind resource, and its energy potential, for a specific site or geographical area.

A description of how well people in a lighted space can see to do visual tasks and how visually comfortable they feel in that space.

The absolute centimeter-gram-second unit of force; that force that will impart to a free mass of one gram an acceleration of one centimeter per second per second.

The transmission of electricity through power lines.

The process of managing the consumption of energy, generally to optimize available and planned generation resources.

The process of the absorption of heat from one location and its transfer to another for rejection or recuperation.

The amount of solar radiation striking a surface per unit of time and area.

A mathematical representation of the frequency or ratio that specific wind speeds occur within a specified time interval.

The regular periodic arrangement of atoms or molecules in a crystal of semiconductor material.

The quantity of heat produced to change a unit weight of a liquid to vapor with no change in temperature.

This designates the resistance of a material to heat conduction. The greater the R-value the larger the number.

A pole used to assist in raising a tower.

A WECS designed to produce electricity.

A device that captures the heat from the exhaust air from a building and transfers it to the supply/fresh fresh air entering the building to preheat the air and increase overall heating efficiency.

A device where sunlight concentrated onto a absorber heats it to a high temperature, and the thermal radiation emitted by the absorber is used as the energy source for a photovoltaic cell that is designed to maximize conversion efficiency at the wavelengt ...

The thermodynamic cycle that is an ideal standard for comparing performance of heat-engines, steam power plants, steam turbines, and heat pump systems that use a condensable vapor as the working fluid; efficiency is measured as work done divided by sensib ...

A registered trademark of an agency of the state of Nebraska, for an automotive fuel containing a blend of 10 percent ethanol and 90 percent gasoline.

A type of motor designed to operate precisely at the synchronous speed with no slip in the full-load speeds (rpm).

An electricity powered device that extracts available heat from one area (the heat source) and transfers it to another (the heat sink) to either heat or cool an interior space or to extract heat energy from a fluid.
