Screening analysis for EPACT-covered commercial HVAC and water-heating equipment

PDF Version Also Available for Download.

Description

EPCA requirements state that if the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) amends efficiency levels prescribed in Standard 90.1-1989, then DOE must establish an amended uniform national manufacturing standard at the minimum level specified in amended Standard 90.1. However, DOE can establish higher efficiency levels if it can show through clear and convincing evidence that a higher efficiency level, that is technologically feasible and economically justified, would produce significant additional energy savings. On October 29, 1999, ASHRAE approved the amended Standard 90.1, which increases the minimum efficiency levels for some of the commercial heating, cooling, and ... continued below

Description

EPCA requirements state that if the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) amends efficiency levels prescribed in Standard 90.1-1989, then DOE must establish an amended uniform national manufacturing standard at the minimum level specified in amended Standard 90.1. However, DOE can establish higher efficiency levels if it can show through clear and convincing evidence that a higher efficiency level, that is technologically feasible and economically justified, would produce significant additional energy savings. On October 29, 1999, ASHRAE approved the amended Standard 90.1, which increases the minimum efficiency levels for some of the commercial heating, cooling, and water-heating equipment covered by EPCA 92. DOE asked Pacific Northwest National Laboratory (PNNL) to conduct a screening analysis to determine the energy-savings potential of the efficiency levels listed in Standard 90.1-1999. The analysis estimates the annual national energy consumption and the potential for energy savings that would result if the EPACT-covered products were required to meet these efficiency levels. The analysis also estimates additional energy-savings potential for the EPACT-covered products if they were to exceed the efficiency levels prescribed in Standard 90-1-1999. In addition, a simple life-cycle cost (LCC) analysis was performed for some alternative efficiency levels. This paper will describe the methodology, data assumptions, and results of the analysis. The magnitude of HVAC and SWH loads imposed on equipment depends on the building's physical and operational characteristics and prevailing climatic conditions. To address this variation in energy use, coil loads for 7 representative building types at 11 climate locations were estimated based on a whole-building simulation.
