This revised handbook provides guidance for promoting behavior-based energy efficiency in U.S. military housing. It discusses the drivers for energy efficiency in military housing, including budget constraints. It recommends planning a campaign by establishing goals, understanding the local context, identifying desired behaviors, selecting communication channels, and incentivizing participation. The handbook also covers designing the campaign, evaluating its impact, and sustaining energy-efficient behaviors over time to achieve long-term savings. The overall aim is to reduce energy use and costs at military bases through community engagement programs.
