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. [5]
More than 75 product categories are eligible for the ENERGY STAR label, including appliances, electronics, lighting, heating and cooling systems, and commercial equipment such as food service products. [6] [7] In the United States, the ENERGY STAR label often appears with the EnergyGuide label of eligible appliances to highlight energy-efficient products and compare energy use and operating costs. [8]
One of the most successful voluntary initiatives introduced by the U.S. government, the program has saved 5 trillion kilowatt-hours of electricity, more than US$500 billion in energy costs, and prevented 4 billion metric tons of greenhouse gas emissions. [9]
Elements of the ENERGY STAR program are implemented in Canada, Japan, and Switzerland. [10] In 2018, a 15-year long agreement with the European Union expired. [11] A previous agreement with the European Free Trade Association also ended. [10]
The Energy Star program was established by the Environmental Protection Agency in 1992 and operates under the authority of the Clean Air Act, section 103(g), and the 2005 Energy Policy Act, section 131 (which amended the Energy Policy and Conservation Act, section 324). [12] [13] [14] Since 1992, Energy Star and its partners are estimated to have reduced various energy bills by at least $430 billion. [15]
The EPA manages Energy Star products, as well as home and commercial/industrial programs. The EPA develops and manages Energy Star Portfolio Manager, an online energy tracking and benchmarking tool for commercial buildings. The DOE manages Home Performance with Energy Star and provides technical support, including test procedure development for products and some verification testing of products. [16]
Initiated as a voluntary labeling program designed to identify and promote energy-efficient products, Energy Star began with labels for computers and their peripherals. In 1995 the program was significantly expanded, introducing labels for residential heating and cooling systems and new homes. [17] In 2000, the Consortium for Energy Efficiency was directed by members to begin an annual survey of Energy Star impact. [18]
According to the U.S. Energy and Employment Report for 2016, 290,000 American workers are involved in the manufacture of Energy Star certified products and building materials. [19] The report also projects that employment in energy efficiency will grow much faster than other areas of the energy sector—9 percent in 2017 vs. average projected growth of 5 percent across all of the energy sector—and that Energy Star will be an integral part of that market.
Energy Star specifications differ with each item, and are set by the EPA.
Energy Star 4.0 specifications for computers became effective on July 20, 2007. The requirements are more stringent than the previous specification and existing equipment designs can no longer use the service mark unless re-qualified. They require the use of 80 Plus Bronze level or higher power supplies. Energy Star 5.0 became effective on July 1, 2009. [20] Energy Star 6.1 became effective on September 10, 2014. Energy Star 7.1 became effective on November 16, 2018. [21] The Version 8.0 specification for computers was finalized on October 15, 2019 and became effective on October 15, 2020. [22]
The EPA released Version 1.0 of the Computer Server specifications on May 15, 2009. It covered standalone servers with one to four processor sockets. A second tier to the specification adding active state power and performance reporting for all qualified servers, as well as blade and multi-node server idle state requirements became effective December 16, 2013. [23] The Version 2.0 Energy Star specification for Computer Servers came into effect on December 16, 2013. The Version 3.0 Energy Star specification for Enterprise Servers came into effect on June 17, 2019 .
As of early 2008, average refrigerators need 20% savings over the minimum standard. Dishwashers need at least 41% savings. Most appliances as well as heating and cooling systems have a yellow EnergyGuide label showing the annual cost of operation compared to other models. This label is created through the Federal Trade Commission and often shows if an appliance is Energy Star rated. [24] While an Energy Star label indicates that the appliance is more energy efficient than the minimum guidelines, purchasing an Energy Star labeled product does not always mean one is getting the most energy efficient option available. For example, dehumidifiers that are rated under 25 US pints (12 L) per day of water extraction receive an Energy Star rating if they have an energy factor of 1.2 (higher is better), while those rated 25 US pints (12 L) to 35 US pints (17 L) per day receive an Energy Star rating for an energy factor of 1.4 or higher. Thus a higher-capacity but non-Energy Star rated dehumidifier may be a more energy efficient alternative than an Energy Star rated but lower-capacity model. [25] The Energy Star program's savings calculator has also been criticized for unrealistic assumptions in its model that tend to magnify savings benefits to the average consumer. [26]
Another factor yet to be considered by the EPA and DOE is the overall effect of energy-saving requirements on the durability and expected service life of a mass-market appliance built to a consumer-level cost standard. For example, a refrigerator may be made more efficient by the use of more insulative spacing and a smaller-capacity compressor using electronics to control operation and temperature. However, this may come at the cost of reduced interior storage (or increased exterior mass) or a reduced service life due to compressor or electronic failures. In particular, electronic controls used on new-generation appliances are subject to damage from shock, vibration, moisture, or power spikes on the electrical circuit to which they are attached. Critics have pointed out that even if a new appliance is energy efficient, any consumer appliance that does not provide customer satisfaction, or must be replaced twice as often as its predecessor contributes to landfill pollution and waste of natural resources used to construct its replacement. [27]
Energy Star qualified heat pumps, boilers, air conditioning systems, and furnaces are available. In addition, cooling and heating bills can be significantly lowered with air sealing and duct sealing. Air sealing reduces the outdoor air that penetrates a building, and duct sealing prevents attic or basement air from entering ducts and lessening the heating/cooling system’s efficiency. Energy Star qualified room air conditioners are at least 10% more energy efficient than the minimum U.S. federal government standards. [28]
Energy Star qualified televisions [29] use 30% less energy than average. In November 2008, television specifications were improved to limit on-mode power use, in addition to standby power which is limited by the current specifications. Standby power consumption for televisions must be 3 watts or less. [30] A wider range of Energy Star qualified televisions will be available.
Other qualified home electronics include cordless phones, battery chargers, VCRs and external power adapters, most of which use 90% less energy.
The Energy Star Program Requirements for Imaging Products are focused on product families such as electrophotographic (EP) printers, inkjet printers (e.g., thermal), copiers, facsimile machines and other imaging equipment including MFD's (multifunctional devices). Typical Electrical Consumption (TEC) of a product family are measured and reported against an allowance set by the maximum throughput of the device. Operation modes (OM) are measured and reported for devices such as inkjet products against an allowance set by the functions present in the EUT (equipment under test). Devices that included "adders" such as Ethernet, on-board memory, wireless, etc. are mathematically "added" to increase the OM allowance. On February 1, 2011, the EPA/DOE added the requirement that all products registered under the Energy Star service mark, must be tested by an AB (Accredited Body) or CB (Certification Body) Laboratory.
The Energy Star is awarded to only certain bulbs that meet strict efficiency, quality, and lifetime criteria. Energy Star qualified fluorescent lighting uses 75% less energy and lasts up to ten times longer than normal incandescent lights. [31]
Energy Star Qualified light-emitting diode (LED) Lighting:
To qualify for Energy Star certification, LED lighting products must pass a variety of tests to prove that the products will display the following characteristics: [34]
New homes or apartments that earn the Energy Star label have been verified to meet energy efficiency requirements set by U.S. EPA. Energy Star certified homes are at least 10% more efficient than homes built to code and achieve a 20% improvement on average, while providing homeowners with better quality, performance, and comfort. [35] Nearly 1.9 million Energy Star certified homes and apartments have been certified to date. [35] These high-performing homes can be found across the U.S. and include a complete thermal enclosure system, a high-efficiency heating, ventilation and cooling system, a comprehensive water management system, and energy-efficient lighting and appliances. [36] Together, U.S. homeowners living in certified homes saved $360 million on their energy bills in 2016 alone. [37] In 2020, ENERGY STAR separated single-family and multifamily construction types into their own programs: Single-Family New Construction (SFNC) and Multifamily New Construction (MFNC). [38]
A new tier of ENERGY STAR certification, called the ENERGY STAR NextGen Certified Homes and Apartments, will be launched in 2023. This new certification uses a baseline of the ENERGY STAR Single-Family and Multifamily certification, with additional requirements such as heat pump water heaters and EV-ready charging capabilities. [39]
The Energy Star program has developed energy performance rating systems for several commercial and institutional building types and manufacturing facilities. These ratings, on a scale of 1 to 100, provide a means for benchmarking the energy efficiency of specific buildings and industrial plants against the energy performance of similar facilities. The ratings are used by building and energy managers to evaluate the energy performance of existing buildings and industrial plants. The rating systems are also used by EPA to determine if a building or plant can qualify to earn Energy Star recognition. [40] In 2020 Energy Star released an updated guide for verifying Energy Star certifications. [41]
Energy Star ratings have been compared to other clean energy rating systems and green building certification systems such as those by independent firms like MiQ, or LEED certifications for office buildings. [42]
The number of space types that can receive the energy performance rating in Portfolio Manager is expanding and now includes housing, [43] bank/financial institutions, courthouses, hospitals (acute care and children's), hotels and motels, houses of worship, K-12 schools, medical offices, offices, residence halls/dormitories, retail stores, supermarkets, warehouses (refrigerated and non-refrigerated), hotels , data centers, senior care facilities, and wastewater facilities. [44] [45]
See the technical descriptions for models used in the rating system at. [46] These documents provide detailed information on the methodologies used to create the energy performance ratings including details on rating objectives, regression techniques, and the steps applied to compute a rating. Energy Star maintains a 1–100 national benchmarking rating for buildings based on building attributes depending on the category, including floor area, occupancy and energy consumption data into a free online tool provided by Energy Star. [47]
Energy Star energy performance ratings have been incorporated into some green buildings standards, such as LEED for Existing Buildings. In the U.S., builders of energy efficient homes are able to qualify for Federal Income tax credits and deductions. [48]
Energy Star estimated in 2020 that energy use in commercial buildings accounts for 20% of greenhouse gas emissions, costing more than $100B per year. [41]
Some examples of specialised industrial facilities which Energy Star has designed specific performance ratings for include: [49] [45]
The U.S. Environmental Protection Agency (EPA) annually recognizes small businesses that demonstrate abilities to reduce waste, conserve energy, and recycle. The businesses use resources and ideas outlined in the Energy Star program. [50] The award was established in 1999.
In March 2010, the Government Accountability Office (GAO) performed covert testing of the Energy Star product certification process and found that Energy Star was for the most part a self-certification program that was vulnerable to fraud and abuse. [51] While the GAO demonstrated, by submitting fake products from made-up companies, that cheating was possible, they found no evidence of consumer fraud relating to the quality or performance of Energy Star qualified products. [51]
In response, the Environmental Protection Agency instituted third-party certification of all Energy Star products starting in 2011. [52] Under this regime, products are tested in an EPA-recognized laboratory and reviewed by an EPA-recognized certification body before they can carry the label. In order to be recognized, labs and certification bodies must meet specified criteria and be subject to oversight by a recognized accreditation body. In addition, a percentage of Energy Star certified product models in each category are subject to off-the-shelf verification testing each year.
As of 2017, there are 23 independent certification bodies and 255 independent laboratories recognized for purposes of Energy Star product certification and testing. [53] Most cover multiple product types. In 2016, 1,881 product models were subject to verification testing with an overall compliance rate of 95%. [54]
In March 2017 the Trump Administration proposed a budget that would eliminate the program. [55] This prompted an outpouring of expressions of support for the Energy Star program from environmental groups, energy efficiency advocates, [56] and businesses. [57]

The following cities have mandatory reporting requirements.
Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively or changing one's behavior to use less and better source of service. Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings.
Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’
Ecolabels and Green Stickers are labeling systems for food and consumer products. The use of ecolabels is voluntary, whereas green stickers are mandated by law; for example, in North America major appliances and automobiles use Energy Star. They are a form of sustainability measurement directed at consumers, intended to make it easy to take environmental concerns into account when shopping. Some labels quantify pollution or energy consumption by way of index scores or units of measurement, while others assert compliance with a set of practices or minimum requirements for sustainability or reduction of harm to the environment. Many ecolabels are focused on minimising the negative ecological impacts of primary production or resource extraction in a given sector or commodity through a set of good practices that are captured in a sustainability standard. Through a verification process, usually referred to as "certification", a farm, forest, fishery, or mine can show that it complies with a standard and earn the right to sell its products as certified through the supply chain, often resulting in a consumer-facing ecolabel.
A low-energy house is characterized by an energy-efficient design and technical features which enable it to provide high living standards and comfort with low energy consumption and carbon emissions. Traditional heating and active cooling systems are absent, or their use is secondary. Low-energy buildings may be viewed as examples of sustainable architecture. Low-energy houses often have active and passive solar building design and components, which reduce the house's energy consumption and minimally impact the resident's lifestyle. Throughout the world, companies and non-profit organizations provide guidelines and issue certifications to guarantee the energy performance of buildings and their processes and materials. Certifications include passive house, BBC—Bâtiment Basse Consommation—Effinergie (France), zero-carbon house (UK), and Minergie (Switzerland).
An energy performance certificate (EPC) is a rating scheme to summarise the energy efficiency of buildings or devices.
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. For example, insulating a building allows it to use less heating and cooling energy while still maintaining a comfortable temperature. Another method is to remove energy subsidies that promote high energy consumption and inefficient energy use. Improved energy efficiency in buildings, industrial processes and transportation could reduce the world's energy needs in 2050 by one third.
The Home Energy Rating is an American estimated measurement of a home's energy efficiency based on normalized modified end-use loads (nMEULs). In the United States, the Residential Energy Services Network (RESNET) is responsible for creation and maintenance of the RESNET Mortgage Industry National Home Energy Rating Standards (MINHERS), a proprietary system of standards, which includes standards language for the certification and quality assurance for RESNET Provider organizations. RESNET is an EPA recognized Home Certification Organization (HCO) that also help's create standards in compliance with the American National Standards Institute, namely ANSI 301, ANSI 310, ANSI 380, and ANSI 850. The Building Science Institute, Ltd. Co. (BSI) is another EPA recognized HCO that maintains the ANSI Standards to produce Energy Ratings and compliance with above-code programs such as the ENERGY STAR New Homes Program.
WaterSense is a program sponsored by the U.S. Environmental Protection Agency (EPA), designed to encourage water efficiency in the United States through the use of a special label on consumer products. The goal of this program is to protect the future of the U.S. water supply. WaterSense maintains partnerships with key utility, manufacturer and retail partners across the United States. WaterSense is voluntary, rather than a regulatory program. The EPA develops specifications for water-efficient products – low-flow fixtures – through a public process. If a manufacturer makes a product that meets those specifications, the product is eligible for third-party testing to ensure the stated efficiency and performance criteria have been met. If the product passes the test, the manufacturer is rewarded with the right to put the WaterSense label on that product.
Miles per gallon gasoline equivalent is a measure of the average distance traveled per unit of energy consumed. MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative fuel vehicles, plug-in electric vehicles and other advanced technology vehicles with the energy consumption of conventional internal combustion vehicles rated in miles per U.S. gallon.
Cathy Zoi is an American business executive, and former CEO of EVgo the US's largest fast charging network for electric vehicles. She is the former Assistant Secretary for Energy Efficiency and Renewable Energy (EERE) at the U.S. Department of Energy.
An energy factor is a metric used in the United States to compare the energy conversion efficiency of residential appliances and equipment. The energy factor is currently used for rating the efficiency of water heaters, dishwashers, clothes washers, and clothes dryers. The term is used by the United States Department of Energy to develop and enforce minimum energy conservation standards under the Energy Conservation Program.
The United States is the second-largest single consumer of energy in the world. The U.S. Department of Energy categorizes national energy use in four broad sectors: transportation, residential, commercial, and industrial. Energy usage in transportation and residential sectors is largely controlled by individual domestic consumers. Commercial and industrial energy expenditures are determined by businesses entities and other facility managers. National energy policy has a significant effect on energy usage across all four sectors.
The Bureau of Energy Efficiency is an agency of the Government of India, under the Ministry of Power, created in March 2002 under the provisions of the nation's 2001 Energy Conservation Act. The agency's function is to encourage the efficient use of energy in India by developing programs to support it. For example, the government proposed to make it mandatory for certain appliances in India to have ratings by the BEE from January 2010 onwards. The mission of the Bureau of Energy Efficiency is to institutionalise energy efficiency services, enable delivery mechanisms in the country and provide leadership to energy efficiency in all sectors of the country. Its primary objective is to reduce energy intensity in the economy.
PECI is a private, non-profit American company based in Portland, Oregon with additional offices in Santa Ana, California and San Francisco, California. PECI designs and manages energy efficiency programs for utility providers, government organizations, and other clients. Some of the organizations PECI has worked with include the U.S. Department of Energy, Avista, Wal-mart, Southern California Edison, the Community Energy Project, Energy Trust of Oregon, Pacific Gas & Electric and the San Diego Natural History Museum.
A green home is a type of house designed to be environmentally sustainable. Green homes focus on the efficient use of "energy, water, and building materials". A green home may use sustainably sourced, environmentally friendly, and/or recycled building materials. This includes materials like reclaimed wood, recycled metal, and low VOC paints. Additionally, green homes often prioritize energy efficiency by incorporating features, such as high-performance insulation, energy-efficient appliances, and smart home technologies that monitor and optimize energy usage. Water conservation is another important aspect, with green homes often featuring water-saving fixtures, rainwater harvesting systems, and grey water recycling systems to reduce water waste. It may include sustainable energy sources such as solar or geothermal, and be sited to take maximum advantage of natural features such as sunlight and tree cover to improve energy efficiency.
In Australia and New Zealand, an energy rating label or energy rating is a label affixed to various appliances prior to retail sale, which allows consumers to compare the energy efficiency of product and allows consumers to know how much power a particular model will use to run. They allow consumers to compare the energy consumption of similar products, and factor lifetime running cost into their purchasing decision. The energy rating label is a mandatory comparison label under Australian regulations for store sales but not for products sold online. The label comprises an energy consumption figure for the appliance and a star rating. The energy consumption figure is an estimate of how much energy the appliance will use over a year, based on assumptions about "average usage".
NABERS, the National Australian Built Environment Rating System is an Australian national initiative, managed by the Government of New South Wales' Department of Climate Change, Energy, the Environment and Water on behalf of the Australian Government, that measures and compares the environmental performance of Australian buildings and tenancies.
The Energy Conservation Program for Consumer Products Other Than Automobiles is a regulatory program that enforces minimum energy conservation standards for appliances and equipment in the United States. The program was established under Part B of Title III of the Energy Policy and Conservation Act of 1975 and gives the Department of Energy (DOE) the authority to develop and implement test procedures and minimum standards for more than 60 products covering residential, commercial and industrial, lighting, and plumbing applications. The Department of Energy is required to set standards that are "technologically feasible and economically justified."
The House Energy Rating (HER) or House Energy Rating Scheme (HERS) are worldwide standard measures of comparison by which one can evaluate the energy efficiency of a new or an existing building. The comparison is generally done for energy requirements for heating and cooling of indoor space. The energy is the main criterion considered by any international building energy rating scheme but there are some other important factors such as production of greenhouse gases emission, indoor environment quality, cost efficiency and thermal comfort, which are considered by some schemes. Basically, the energy rating of a residential building provides detailed information on the energy consumption and the relative energy efficiency of the building. Hence, HERs inform consumers about the relative energy efficiency of homes and encourage them to use this information in making their house purchase decision.
The SNIA Emerald Program Power Efficiency Measurement Specification, is a storage specification developed and maintained by the Storage Networking Industry Association (SNIA) and cross-referenced by the Environmental Protection Agency’s EnergyStar program. The specification consists of a storage types taxonomy, system under test workload and energy measurement method, measured metrics for active and idle operational states, and presence tests for capacity optimization technologies. The measured metric data is generated through the use of well-defined standard testing and data reduction procedures prescribed in the SNIA Emerald Specification.
ENERGY STAR® is a joint program of the Environmental Protection Agency (EPA) and the Department of Energy (DOE). Its goal is to help consumers, businesses, and industry save money and protect the environment through the adoption of energy-efficient products and practices. The ENERGY STAR label identifies top-performing, cost-effective products, homes, and buildings.
ENERGY STAR is administered by the U.S. Environmental Protection Agency. Thousands of organizations—including nearly 40% of the Fortune 500®—partner with ENERGY STAR. Together with EPA, they deliver cost-saving energy efficiency solutions that protect the climate, improve air quality, and protect public health.
The ENERGY STAR program is administered by the U.S. Environmental Protection Agency (EPA). ENERGY STAR is a voluntary labeling program: EPA sets energy efficiency specifications and those that meet them can choose to display the ENERGY STAR logo. In turn, consumers and businesses who want to save energy and money can look for the ENERGY STAR label when making buying decisions.
Products must achieve high levels of energy efficiency set by the U.S. Environmental Protection Agency (EPA) in order to earn the ENERGY STAR label. Over 75 types of products can earn the label, in categories such as appliances, electronics, lighting, heating and cooling, and commercial products such as food service equipment. In order to receive certification, products must undergo a three-step process.
Both the EnergyGuide and the ENERGY STAR labels are intended to help you make smart energy choices. Used in conjunction, these labels can help you choose which product is right for you. The ENERGY STAR label will help you easily identify which products are the most efficient options, and then the EnergyGuide can be used to directly compare your top choices and give you an estimate of the energy use and operating cost. Saving energy is good for your wallet and good for the climate.
The U.S. Environmental Protection Agency launched the ENERGY STAR program in 1992. Since then, ENERGY STAR has grown to become the international standard for energy efficiency and one of the most successful voluntary U.S. government programs in history...
