Systems-Level Energy Audit for Main Complex, Construction Engineering Research Laboratory

摘要

As a result of the CERL sustainability workshop, a Phase I energy audit was conducted for CERL main complex (Buildings 1, 2, and 3) was conducted. The goals of the audit were to review energy and water use in the current main complex building, to review and inventory energy system equipment, and to devise short- and long-term energy improvement and water conservation strategies. Baseline references on utilities consumptions and costs were developed to help future periodic monitoring efforts. This report documents facility and energy systems information and energy management and water conservation opportunities identified in this study. A 40 percent reduction in building energy use is needed for CERL to meet the Army facility energy goal (by reducing the current Energy Use Index EUI of 160 KBtu/sq ft/yr to below 100 KBtu/sq ft /yr). Despite completion of several energy conservation projects at the CERL complex, it was found that the EUI has been increasing since 1998. Factors that likely contributed to this increase were summer air dehumidification (starting in FY00) and inadequate building insulation. Specific short- and long-term energy improvement strategies were recommended to address the site's water- and energy-conservation issues.
