U.S. Lighting Market Characterization. Volume 1: National Lighting Inventory and Energy Consumption Estimate;Final rept

摘要

The Lighting Market Characterization study is a multiyear program to evaluate light sources in the United States, and identify opportunities for saving energy. Sponsored by the United States Department of Energy's (DOE's) Building Technologies Program (BT), the Lighting Market Characterization consists of two phases. This report, Phase I, provides an estimated inventory of installed lighting technologies for 2001 and their associated energy consumption. Phase II will evaluate this inventory and research lighting technologies to identify energy saving opportunities. The objective of Phase I is to collect and present in one document the fundamental energy consumption information that DOE needs to plan an effective lighting research and development (LR&D) program. This report answers three main questions: How much energy is consumed by light sources in the United States; How many lighting technologies are installed, where are they installed, and what area do they illuminate; and What are the performance attributes of the installed stock of lighting technologies. This report attempts to answer these questions at the right level of aggregation and as uniformly as possible across end-use sectors. This study draws data from existing sources such as the Commercial Building Energy Consumption Survey (CBECS) and the Manufacturing Energy Consumption Survey (MECS), as well as previously untapped data sources such as end-use metering studies and building audits. Two important features that distinguish this study from prior efforts are its use of new data sources, and its analysis by applications that cut across building sectors.
