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.
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. Stand-alone swimming pools are not eligible to earn the ENERGY STAR score. However, because swimming pools are a common energy-intensive amenity at other commercial building types (i.e., hotels and schools), the ENERGY STAR score does make adjustments to accommodate for the presence of swimming pools.
The ENERGY STAR Score for Warehouses applies to buildings that are used to store goods, manufactured products, merchandise, or raw materials, including non-refrigerated warehouses, refrigerated warehouses, and distribution centers. The objective of the ENERGY STAR score is to provide 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.
The ENERGY STAR Score for Wastewater Treatment Plants applies to primary, secondary, and advanced treatment facilities with or without nutrient removal capacity. The objective of the ENERGY STAR score is to provide 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. To identify the aspects of building activity that are significant drivers of energy use and then normalize for those factors, a statistical analysis of the peer building population is performed.
The ENERGY STAR Score for Worship Facilities applies to churches, temples, mosques, synagogues, meetinghouses, or any other buildings that primarily function as a place of religious worship. The objective of the ENERGY STAR score is to provide 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.
Download this three-page list of property types available in ENERGY STAR® Portfolio Manager®. Portfolio Manager has more than 80 property types from which to choose when setting up your property. The expanded list of property types offers you the ability to define and categorize properties. View the list of Portfolio Manager property types, definitions, and use details for more information.
When you benchmark your building in Portfolio Manager, one of the key metrics you’ll see is energy use intensity, or EUI. Essentially, the EUI expresses a building’s energy use as a function of its size or other characteristics.
For most property types in Portfolio Manager, the EUI is expressed as energy per square foot per year. It’s calculated by dividing the total energy consumed by the building in one year (measured in kBtu or GJ) by the total gross floor area of the building.
The climate of the area where your property is located and the annual fluctuations you experience in weather conditions can affect how much energy you need to operate your buildings. Portfolio Manager includes metrics designed to incorporate these effects and help you understand your energy performance. These procedures rely on temperature data collected by weather monitoring stations and published by the National Climatic Data Center (NCDC), which is part of the National Oceanic and Atmospheric Administration (NOAA).
EPA’s 1 - 100 ENERGY STAR score is an external benchmark for assessing the performance of commercial buildings. The ENERGY STAR score, expressed as a number on a simple 1 - 100 scale, rates performance on a percentile basis: buildings with a score of 50 perform better than 50% of their peers; buildings earning a score of 75 or higher are in the top quartile of energy performance.
The objective of the water score is to provide a fair assessment of the water use performance of a property relative to its peers, taking operational characteristics of the property and impact of climate into account. A statistical analysis is performed to identify building parameters that are significant drivers of water use using multivariate regression analysis, resulting in an equation that predicts the Water Use Intensity (WUI) of a property.
When establishing energy performance targets early in a project’s design stage, exact fuel mix and energy costs are often not known. In these cases, Portfolio Manager and Target Finder will provide an estimated fuel mix and energy cost to help you assess how to reach your target performance level. Reference this 7-page document for information about using Portfolio Manager and Target Finder to estimate fuel mix and energy cost.
