In this study, published information on nonprocess energy use, which includes lighting, heating, cooling, ventilation, humidity control, and particulate control, for industrial buildings has been analyzed and compiled and then represented in power intensity (W/ft2). More than thirty different sources of data related to industrial building energy use (covering about 82 buildings) were identified and analyzed. Energy receives a lot of consideration in analyzing prospective savings in industrial facilities since the industrial sector consumes more than 30% of the total energy in the U.S. The main objective of this study is to establish representative ranges for non-process energy use that can then be used with full process the life cycle for industrial products. The industrial manufacturing buildings were classified into six categories according to non-process energy use. The power intensity for each building category was estimated from the available data. Previous analyses of industrial energy use often expressed non-process energy as a percentage of total energy but without clear values of actual non-process energy. This information is a low value since the actual nonprocess energy is then dominated by the dominator which is unspecified.
