This two page document provides an overview of the ENERGY STAR Energy Performance Indicator (EPI) for Fluid Milk and Yogurt Processing Plants. It describes what types of plants can use the use EPI, the data required to use the EPI, and background on ENERGY STAR certification.
This FAQ describes the 2009 upgrade to EPA's 1-100 ENERGY STAR score for hotels. The document explains the changes made to the scoring model, including a new data source, the updated analysis of energy use per square foot, and service levels based on operating characteristics.
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.
This checklist must be completed by the Professional Engineer conducting the verification for ENERGY STAR industrial plant certification. The completed checklist must be scanned as PDF and included with the application materials sent to EPA. The original checklist must be kept in the plant's certification file. This checklist can also be found in Appendix 3 of the Professional Engineers’ Guide for Validating Statements of Energy Performance.
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.
