As the global standard for energy efficiency in appliances, Energy Star is embraced in the United States, European Union, as well as Japan and Australia. According to the program’s guidelines, products certified by Energy Star often obtain an improvement of at least 20% relative to standard consumer products. Competing standards include the European TCO efficiency certification, which also includes ergonomics in factoring in its environmental efficiency.
Originated by the EPA in 1992, the goal of the program began to help encourage households to reduce global warming emissions. The program has expanded its certification to cover electronics, appliances and even construction projects, where over 10% of new home construction is accredited as Energy Star certified. The program has also led to innovations in more efficient lighting systems, automated power management and renewable resources.
In order to qualify for an Energy Star certification, appliances must meet base energy savings guidelines for appliances, heating and cooling systems, electronics and lighting. The energy performance certification for buildings is based on measures of efficiency in insulation, construction, heading and cooling, as well as water and lighting systems.
Home owners seeking to lower their energy costs are advised to consider Energy Star certification as a good baseline measure of the efficiency for new appliances. However, total costs and energy utilization measures should also be taken into account when making an investment decision; a smaller device with a lower efficiency may be preferred over a larger capacity device that has a higher conversion rating. By taking a comprehensive approach to efficiency measures, home owners can save on their energy costs and reduce major heating and electricity bills throughout the year.
