ENERGY STAR products are independently certified to save energy without sacrificing features or functionality. Saving energy helps prevent climate change. Look for the ENERGY STAR label to save money on your energy bills and help protect our environment.
Improving your home's energy efficiency with ENERGY STAR can help to lower high energy bills, improve comfort and reduce greenhouse gas emissions. Learn about the many ways to save in your home and track your progress with "My ENERGY STAR" - your new dashboard to savings.
A new home or apartment that has earned the ENERGY STAR label has undergone a process of inspections, testing, and verification to meet strict requirements set by the US EPA. ENERGY STAR certified homes and apartments use significantly less energy than typical new homes and apartments while delivering better comfort, quality, and durability.
This paper reports on the work of EPA and the integrated steel industry to develop an Energy Performance Indicator (EPI) for integrated mills that develop and manufacture steel in the United States. The paper describes the data and statistical methods used to construct the EPI for evaluating the energy performance of integrated steel mills in the U.S. and Canada.
This report describes the data and statistical methods used to construct the Energy Performance Indicator (EPI) for commercial bread and roll bakeries. It reviews how the EPI was developed to provide a plant-level indicator of energy performance by working with the baking industry. The report also presents the individual equations used in the EPI.
This report describes the data and statistical methods used to construct the Energy Performance Indicator (EPI) for integrated steel mills. It also explains how the EPI was developed to provide a plant-level indicator of energy efficiency by working with the steel industry. This report is useful if you would like background information on how EPA's ENERGY STAR Integrated Steel Mill EPI was developed. The report presents the individual equations used to develop the EPI.
This report describes the data and statistical methods used to construct the Energy Performance Indicator (EPI) for metal casting plants. It also explains how the EPIs were developed to provide a plant-level indicator of energy efficiency by working with the metal casting industry. This report is useful if you would like background information on how EPA's ENERGY STAR metal casting plant EPIs were developed. The report presents the individual equations used to develop the EPIs.
This report describes the data and statistical methods used to construct the Energy Performance Indicators (EPIs) for automobile powertrain (engine & transmission) plants. It reviews how the EPIs were developed to provide plant-level indicators of energy performance by working with the motor vehicle industry. The report also presents the individual equations used in the EPI.
Energy costs typically account for 5-7% of the overall operating costs in a metal casting foundry. Energy waste is found in all plants, and improving energy efficiency goes right to the bottom line. Following the procedures outlined in this guide will reduce your energy costs (and dollars spent) per ton of cast metal while improving your environmental reputation as well as image in the community.
Use this spreadsheet to easily convert common energy units to BTUs and Source Energy BTUs. If your site participates in the ENERGY STAR Challenge for Industry, you can use the total source MMBTU provided in the QuickConverter to track your energy use. Industrial sites who sign up for EPA's ENERGY STAR Challenge for Industry commit to improve their energy efficiency by 10% within five years.
This document provides guidance for Professional Engineers on the validation process of the ENERGY STAR plant certification Statement of Energy Performance.
The ENERGY STAR score provides a fair assessment of the energy performance of a property relative to its peers, taking into account the climate, weather, and business activities at the property. In the United States, data centers are able to earn the ENERGY STAR score using an energy intensity metric that takes into consideration the IT Energy used by the data center (see the Technical Reference for the ENERGY STAR Score for Data Centers for more details). For data centers within a larger property, it can sometimes be difficult for property managers to obtain IT Energy.
