The interior space of a building that is heated or cooled.

A thermodynamic property of a substance, defined as the sum of its internal energy plus the pressure of the substance times its volume, divided by the mechanical equivalent of heat. The total heat content of air; the sum of the enthalpies of dry air and w ...

Insulation made from rockwool fibers, fiberglass, cellulose fiber, vermiculite or perlite minerals, and composed of loose fibers or granules can be applied by pouring directly from the bag or with a blower.

A solar energy system that produces electricity with a PV module, and collects thermal energy from the module for heating. There are no commercially available systems available (as of 11/97).

An instrument used to measure changes in the level of the water in an evaporation pan. The gauge is normally placed in a Stillwell and adjusted so that the point of the hook just breaks the water surface. The change in water level is read on the attached ...

The bearing surrounding the propeller shaft where it exits the hull.

A system where heat is supplied to areas of a building from a single appliance through a network of ducts or pipes.

The device that reduces the pressure of liquid refrigerant thereby cooling it before it enters the evaporator coil in a heat pump.

Filtering device used to remove the solid debris from the cooling water.

A filtering unit for vented enclosures installed to prevent dirt and foreign matter from entering the enclosure.

The tall, narrow, waterproof box that houses a vessel's centerboard and allows it to be retracted into the ship's hull.

Stocks whose dividend payouts are high as a proportion of their share price. This could either be.

A company quoted on the London Stock Exchange which invests its shareholders' funds in the shares.

A photometer which measures the intensity of radiation as a function of the frequency (or wavelength) of the radiation.

A cylinder installed in a body of water or an evaporation pan to hold a sensor, such as a float to measure water level or a hook gage. The stillwell is constructed so that there is free movement of water in and out of it, and it therefore provides a repre ...

A group of solar photovoltaic modules connected together.

A small low rail around the deck of a boat. The toe rail may have holes in it to attach lines or blocks and to allow drainage. A larger wall is known as a gunwale.
