Abstract

The paper describes the application of a methodology and tools for early assessment of integrated system solutions for deep retrofit with a potential of 30-50% energy reductions across large building portfolio as well as at an individual building scale using information only about building characteristics, usage type and climate. The building energy consumption is estimated using a simple building description, and then the impact of energy conservation measures (ECMs) are estimated individually and in combination as integrated system packages. We demonstrate the tool application with two types of cases from the Department of Defense (DoD) real property database. The results illustrate both statistical analysis of the potential for deep retrofits at DoD portfolio level, which comprises nearly 250,000 facilities in the U.S., and also for a few representative existing DoD buildings.
