【 摘 要 】

The State Energy Conservation Office of Texas has asked the U.S. Department of Energy to analyze the potential energy effect and cost-effectiveness of the lighting requirements in the 2003 IECC as they consider adoption of this energy code. The new provisions of interest in the lighting section of IECC 2003 include new lighting power densities (LPD) and requirements for automatic lighting shutoff controls. The potential effect of the new LPD values is analyzed as a comparison with previous values in the nationally available IECC codes and ASHRAE/IESNA 90.1. The basis for the analysis is a set of lighting models developed as part of the ASHRAE/IES code process, which is the basis for IECC 2003 LPD values. The use of the models allows for an effective comparison of values for various building types of interest to Texas state. Potential effects from control requirements are discussed, and available case study analysis results are provided but no comprehensive numerical evaluation is provided in this limited analysis effort.
