Examples
- A refrigerating appliance is required to maintain temperatures inside its compartments within specified limits, and to operate (including defrosting) in a specified ambient temperature while using at most a specified amount of electricity; the energy use allowed varies according to volume, number of doors, the function of the various compartments and other parameters. This graph shows the dramatic reduction in electricity use in U.S. refrigerators following the introduction of a series of first California then U.S. MEPS starting in the mid-1970s:
- An electric fan is required to shift air at a specified rate while consuming a limited amount of power.
A storage water heater providing hot water for sanitary purposes is required to heat up a specified quantity of water to a specified temperature and store it at that temperature for a specified time while consuming a limited amount of energy. In this example, the requirements for heating up and for maintaining the temperature may be applied as two separate energy performance requirements or there may be a single task efficiency.
- An electric induction motor is required to have a specified minimum full-load efficiency.
A compact fluorescent lamp is required to start and run-up to near full brightness in a given time, to have a minimum life of several thousand hours, to maintain its output within specified limits, to withstand a certain number of switchings, to have a consistent colour appearance and a specified colour rendering. Its energy performance requirement is usually stated in terms of minimum efficacy (light output per electrical input).

Famous quotes containing the word examples:
“In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
—Michel de Montaigne (1533–1592)
“There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.”
—Bernard Mandeville (1670–1733)
“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)
