One of the main goals of the ENERGY STAR program is to develop performance-based specifications that determine the most efficient products in a particular category. Products that meet these specifications earn the ENERGY STAR label.
To develop ENERGY STAR product specifications, EPA and DOE use a systematic process that relies on rigorous market, engineering, and pollution savings analyses as well as input from industry stakeholders. During the ENERGY STAR product specification development and revision process, EPA employs a set of key six Guiding Principles (151KB) to ensure that ENERGY STAR:
EPA and DOE continually develop new ENERGY STAR specifications to expand the program to new products.
ENERGY STAR specifications are then periodically revised to ensure relevancy under current market conditions. EPA and DOE strive to make certain that specifications differentiate the most efficient products and move the market toward more energy-saving designs.
EPA recently launched two new ENERGY STAR product specifications: commercial water heaters and residential pool pumps. The Version 1.0 ENERGY STAR Commercial Water Heaters specification took effect on 3/20/2013. The Version 1.0 covers water heaters marketed for sale in the commercial market and sets requirements for Thermal Efficiency, Standby Loss and Energy Factor requirements for gas water heaters. The Version 1.0 ENERGY STAR Pool Pump specification took effect on 2/15/2013. The Version 1.0 covers single phase residential inground pool pumps rated greater than 0.5 total HP and less than or equal to 4 total HP, and sets requirements for Energy Factor and onboard pump controls default speed settings.
