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. PNNL presents the results of this analysis in the development of the LEUI metric and inputs, showing that the LEUI gives commercial building owners and tenants a quantifiable tool for working together to improve energy efficiency in commercial buildings.
This 6-page document outlines proposed criteria for a new tenant-based EPA recognition for energy efficiency, and poses specific questions to solicit input from tenants, landlords, and other stakeholders in all commercial building sectors. EPA accepted comments until November 14, 2016. The comment period is now closed. Check the About "Tenant Star" page for updates.
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.
