The arrangement, proportion, and design of windows in a building.

A device that tracks the movement of the sun; used to orient solar concentrating systems.

A device used to control temperatures; used to control the operation of heating and cooling devices by turning the device on or off when a specified temperature is reached.

A unit of measurement for the ability of a material to retard the diffusion of water vapor at 73.4 F (23 C). A perm, short for permeance, is the number of grains of water vapor that pass through a square foot of material per hour at a differential vapor p ...

A battery-powered electrically driven vehicle.

The sum of all the costs both recurring and nonrecurring, related to a product, structure, system, or service during its life span or specified time period.

A construction element that inhibits termites from entering building foundations and walls.

A device for converting continuous circular motion into reciprocating rectilinear motion.

The amount of energy derived from an electrical source per unit quantity of electricity passing through the source.2. Electrical potential; voltage.

A curve that indicates the number of hours per year that specific wind speeds occur.

A registered trademark name for houses built with tires, aluminum cans, and earth.

A heat exchanger for recovering heat from flue gases for heating water or air.

A measure of the electrical resistance of a material equal to the resistance of a circuit in which the potential difference of 1 volt produces a current of 1 ampere.

A mechanical/electrical device used to pull air out of an interior space; usually located in the highest location of a building, in the ceiling, and venting to the attic or directly to the outside.

The distance between similar points on successive waves.

The effect of cooling by the radiation of heat from a building to the night sky.

The wind speed with 50 percent probability of occurring.

The transfer of heat through a material by the transfer of kinetic energy from particle to particle; the flow of heat between two materials of different temperatures that are in direct physical contact.

A system capable of rotating about one axis.

Ventilation that is created by the differences in the distribution of air pressures around a building. Air moves from areas of high pressure to areas of low pressure with gravity and wind pressure affecting the airflow. The placement and control of doors ...
