    en.wikipedia.org/wiki/Energy_Star

    Energy Star (trademarked ENERGY STAR) is an energy-efficiency program administered by the U.S. Environmental Protection Agency (EPA) in partnership with the U.S. Department of Energy (DOE). [ 2 ] [ 3 ] [ 4 ] The EPA establishes energy efficiency specifications, and those that meet these specifications are eligible to display the ENERGY STAR logo.

    en.wikipedia.org/wiki/ASHRAE_90.1

    Compared to 90.1-2010, 90.1-2013 is expected to save approximately 8.7% in energy cost, 8.5% in source energy and 6.7% in site energy. [ 9 ] Updates to the building envelope section of 90.1-2013 include changes to the prescriptive opaque envelope and fenestration performance requirements in several climate zones and modifications to the ...

    en.wikipedia.org/wiki/Water_heating

    [citation needed] (In neither case is the energy expended exploring, developing and extracting coal or natural gas resources included in the quoted efficiency numbers.) Gas tankless water heaters shall have an energy factor of 82% or greater under the 2015 standards, which corresponds to the pre-2015 Energy Star standard.

  5. Seasonal energy efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/Seasonal_energy_efficiency...

    The energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTUs) to input electrical energy (in watt-hours) at a given operating point. EER is generally calculated using a 95 °F (35 °C) outside temperature and an inside (actually return-air) temperature of 80 °F (27 °C) and 50% relative humidity.

Lock out, tag out or lockout–tagout (LOTO) is a safety procedure used to ensure that dangerous equipment is properly shut off and not able to be started up again prior to the completion of maintenance or repair work.

  8. European Union energy label - Wikipedia

    en.wikipedia.org/wiki/European_Union_energy_label

    A new energy label, introduced in 2010, is based on the energy efficiency index (EEI), and has energy classes in the range A+++ to D. [11] The EEI is a measure of the annual electricity consumption, and includes energy consumed during power-off and standby modes, and the energy consumed in 220 washing cycles. For the washing cycles, a weighted ...
