  2. Minimum energy performance standard - Wikipedia

    en.wikipedia.org/wiki/Minimum_energy_performance...

    MEPS and energy rating labels help improve the energy efficiency of our [who?] products, and enable consumers to choose products that use less energy. Products covered by MEPS must meet or exceed set levels for energy performance before they can be sold to consumers. MEPS have been updated over the years (2002, 2003, 2004, 2008, 2011) to cover ...

  3. 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 ...

  4. Energy efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency

    Energy efficiency may refer to: Energy efficiency (physics), the ratio between the useful output and input of an energy conversion process Electrical efficiency, useful power output per electrical power consumed; Mechanical efficiency, a ratio of the measured performance to the performance of an ideal machine

  5. Efficient energy use - Wikipedia

    en.wikipedia.org/wiki/Efficient_energy_use

    Common energy efficiency label on appliances to indicate their energy efficiency in a clear manner. Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.

    Depiction of New York World Building fire in New York City in 1882. Building codes in the United States are a collection of regulations and laws adopted by state and local jurisdictions that set “minimum requirements for how structural systems, plumbing, heating, ventilation, and air conditioning (), natural gas systems and other aspects of residential and commercial buildings should be ...

  7. Energy performance certificate - Wikipedia

    en.wikipedia.org/wiki/Energy_performance_certificate

    Energy performance certificates (EPCs) are a rating scheme to summarise the energy efficiency of buildings. [4] [5] The building is given a rating between A (Very efficient) - G (Inefficient). The EPC will also include tips about the most cost-effective ways to improve the home energy rating. Energy performance certificates are used in many ...

  8. EnergyGuide - Wikipedia

    en.wikipedia.org/wiki/EnergyGuide

    [4] The first appliance labeling rule was established in 1979 and all products were required to carry the label starting in 1980. Energy Star is a similar labeling program, but requires more stringent efficiency standards for an appliance to become qualified, and is not a required program, but rather a voluntary one.

  9. Energy-related products - Wikipedia

    en.wikipedia.org/wiki/Energy-related_products

    The goal is the reduction of energy along the supply chain: from the design stage throughout production, transport, packaging and so on. Products that comply with this directive are easily recognized by carrying the CE marking. In this case, the CE mark covers product safety and energy efficiency requirements. [1]
