This 23-page technical document describes the lighting energy unit intensity (LEUI) metric developed by Pacific Northwest National Laboratory (PNNL) in support of EPA’s ENERGY STAR Tenant Space recognition.
PNNL lighting researchers studied and analyzed traditional lighting power density (LPD) in energy codes. PNNL also studied the Leadership in Energy Efficient Design (LEED) rating system, the Urban Land Institute (ULI), and the Green Mark for Office Interiors program in Singapore.
Use this six-page document to stipulate that a commercial new construction building project and the completed building meet the U.S. Environmental Protection Agency’s (EPA) energy performance criteria to achieve ENERGY STAR® certification.
This tip sheet draws on insights from companies that have adapted their treasure hunt methods to address safety concerns created by COVID-19 and have successfully conducted treasure hunts. Every energy program will need to assess what is possible given their organization’s new safety requirements.
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 report describes the data and statistical methods used to construct the Energy Performance Indicators (EPIs) for fluid milk processing plants. It reviews how the EPIs were developed to provide plant-level indicators of energy performance by working with the dairy industry. The report also presents the individual equations used in the EPI.
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.
