Energy Reduction Strategies for Existing Air Force Healthcare Facilities

SMArchS Thesis, Building Technology, Spring 2013

Federal buildings are required to reduce 30% of their energy use intensities by 2015 and 37.5% by 2020. Despite rigorous efforts, current Air Force healthcare building performance reveals only a 15% decrease has been achieved from the 2009 baseline levels. Projections similarly reveal full compliance by 2020 may not be achievable, therefore, the need for a comprehensive and more robust effort is proposed.

This thesis seeks to develop a road map for the Air Force’s 68 existing healthcare buildings towards compliance by 2015. A methodology has been developed that leverages the Air Force’s state-of-the-art energy efficiency strategy, the energy performance analysis for 68 healthcare facilities and multi-agency interviews. Findings indicate an energy master plan and a systematic building diagnostics approach that targets HVAC equipment and system operations as the most effective strategy. The results reveal that HVAC retrofits and implementation of no cost measures such as temperature set points and setbacks collectively reduce building energy use by 85% and energy use intensities by 50% by 2015.
