Energy efficiency
Nocturnal cooling
Energy; Energy efficiency
The effect of cooling by the radiation of heat from a building to the night sky.
Electrical current
Energy; Energy efficiency
The flow of electrical energy (electricity) in a conductor, measured in amperes.
Heat transfer
Energy; Energy efficiency
The flow of heat from one area to another by conduction, convection, and/or radiation. Heat flows naturally from a warmer to a cooler material or space.
Low-flow solar water heating systems
Energy; Energy efficiency
The flow rate in these systems is 1/8 to 1/5 the rate of most solar water heating systems. The low-flow systems take advantage of stratification in the storage tank and theoretically allows for the ...
Collector fluid
Energy; Energy efficiency
The fluid, liquid (water or water/antifreeze solution) or air, used to absorb solar energy and transfer it for direct use, indirect heating of interior air or domestic water, and/or to a heat storage ...
Capability margin
Energy; Energy efficiency
The difference between net electrical system capability and system maximum load requirements (peak load); the margin of capability available to provide for scheduled maintenance, emergency outages, ...
