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.
Global leaders within the data center industry developed a consistent set of global metrics for measuring energy efficiency and greenhouse gas emissions. This protocol provides the agreed-on measurement protocols for PUE, Green Energy Coefficient (GEC), Energy Reuse Factor (ERF), and Carbon Usage Effectiveness (CUE). This document, dated October 2, 2012, also discusses agreements that have been reached to date.
In response to a 2007 Congressional request, EPA developed this 133-page report to assess current trends in energy use and energy costs of data centers and servers in the U.S., and to outline existing and emerging opportunities for improved energy efficiency. It provides particular information on the costs of data centers and servers to the federal government and opportunities for reducing those costs through improved efficiency.
This report from the U.S. Green Building Council explains how high performing buildings show proven cost-effectiveness, boost employee productivity, enhance tenant health, reduce liability for owners, and increase a building's property value. Certification programs like LEED and ENERGY STAR are creating common benchmarks, support tools and opportunities for the public which offer market differentiation and create higher value for buildings.
Use this guide to learn best practices for energy-efficient data center design. The guide covers the Information Technology (IT) systems and their environmental conditions, data center air management, cooling and electrical systems, on-site generation, and heat recovery. This guide was created by the U.S. Department of Energy.
Read this guidance to understand and implement the standardized energy efficiency measurements, metrics, and reporting conventions for data centers. The document also contains contact information for industry leaders developing the national guidance standards.
