ENERGY STAR for Tenant Spaces: Lighting Analysis
Last updated: 10-13-2020
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.
