The process of building sustainable communities requires careful coordination between a number of stakeholders, including master planners, energy planners, and building designers.Within theU.S. Department of Defense, these stakeholders work at differing levels of detail and use different planning horizons, which may lead to suboptimimal decisions for the community as a whole. This paper describes a new approach to adapt energy planning processes and tools to scale smoothly between the master planning level, involving thousands of buildings, to the facility design level, involving single buildings. The concept of an energy and sustainability overlay and use of design targets is presented. Examples are provided using the net zero planner tool from studies performed at a U.S. Army installations.
