The Army is required by law to eliminate fossil fuel use in new and renovated facilities by 2030 and to reduce overall facility energy usage by 30 by 2015. Army policy is to achieve net zero energy NZE status for all installations by 2058. Achieving NZE will only be possible if an optimum mix of demand reduction and renewable sources are put in place at a community installation or building cluster scale. There is a lack of tools and case studies that address dynamics of energy systems at the community scale. The Armys future building energy requirements are a mixture of ultra-low and high energy intensity facilities. Achieving net zero energy economically in these clusters of buildings will require a seamless blend of energy conservation in individual buildings, combined with building systems automation, utility management and control, and power delivery systems with the capability to integrate onsite power generation including from renewable energy sources and energy storage. When buildings are clustered together, after each building is designed to its economic energy efficient option, the building cluster is also energy optimized taking advantages of the diversification between energy intensities, scheduling, and waste energy streams utilization. The optimized cluster will minimize the amount of renewables needed to make the building cluster net zero. This paper describes this process and demonstrates it using as an example a cluster of buildings a Brigade Combat Team Complex at Fort Bliss, TX.
