Energy Conservation Program for Certain Industrial Equipment: Energy Conservation Standards for Commercial Water Heating Equipment

摘要

The U.S. Department of Energy (DOE) is initiating a rulemaking to consider amended energy conservation standards for commercial water heaters, hot water supply boilers, and unfired hot water storage tanks (commercial water heating equipment). Once completed, this rulemaking will fulfill DOE's statutory obligation to either propose amended energy conservation standards for commercial water heating equipment or to determine that the existing standards do not need to be amended. This notice seeks to solicit information to help DOE determine whether national standards more stringent than those currently in place would result in a significant amount of additional energy savings and whether such amended national standards would be technologically feasible and economically justified. In overview, this document presents a brief description of the analysis DOE plans to perform for this rulemaking and requests comment on various issues relating to each of the analyses (e.g., market assessment, engineering analysis, energy use analysis, life-cycle cost and payback period analysis, and national impact analysis). Although this document contains several specific topics on which DOE is particular
