A window glass that has been coated with a reflective film and is useful in controlling solar heat gain during the summer.

A solar thermal system that has one tank for storing solar heated water to preheat the water in a conventional water heater.

A unit of electricity consumption of one Watt over the period of one hour.

A study of the transformation of energy from one form to another, and its practical application. (see Law(s) of Thermodynamics above).

Air that is taken from the outdoors.

Energy conversion technologies that harness the energy in tides, waves, and thermal gradients in the oceans.

The process of converting materials that are no longer useful as designed or intended into a new product.

SMES technology uses the superconducting characteristics of low-temperature materials to produce intense magnetic fields to store energy. SMES has been proposed as a storage option to support large-scale use of photovoltaics and wind as a means to smooth ...

A device used to remove particulate matter from the waste gasses of a combustion power plant.

A device for measuring light intensity that works by converting light falling on, or reach it, to electricity, and then measuring the current; used in photometers.

Caulking and weatherstripping to reduce air infiltration and exfiltration into/out of a building.

A mechanism used by electric utilities to determine prices for electricity; typically defines rates according to amounts of power demanded/consumed during specific time periods.

Air that is returned from a heated or cooled space, reconditioned and/or cleaned, and returned to the space.

As a component of a heating or cooling appliance, rows of tubing or pipe with fins attached through which a heat transfer fluid is circulated and to deliver heat or cooling energy to a building.

An electrical generator that runs at a constant speed and draws its excitation from a power source external or independent of the load or transmission network it is supplying.

An architectural design invented by Buckminster Fuller with a regular polygonal structure based on radial symmetry.

To allow or augment the natural movement of cooler air from exterior, shaded areas of a building through or around a building.

This device can automatically turn the heater off at night and on in the morning.

The component of a central receiver solar thermal system where reflected solar energy is absorbed and converted to thermal energy.

The supportive structure of a building.
