Energy Conservation in U.S. Army Industrial Facilities

1. Energy Conservation in U.S. Army Industrial Facilities Investigators: William M. Worek, MIE; Michael J. Chimack, MIE; Robert Miller, MIE; Andrew Sheaffer, MIE; Jonathan Aardsma, MIE; Noel Corral; MIE Prime Grant Support: Construction Engineering Research Laboratory Problem Statement and Motivation Executive Order 13123 requires all Army industrial facilities to reduce energy consumption by 25% from their 1990 baselines by 2010. Many Army industrial processes are unique and the installations are unable to quantify, or control their energy consumption. Energy consumption baselines for each process must be established to measure efficiency improvements In addition, an overall understanding of material demand and waste generation must be achieved in order to meet the Federal mandate, maintain mission readiness, and improve process efficiency. Welding on an Armored Personnel Carrier in an Army Arsenal Technical Approach Key Achievements and Future Goals • A number of Army industrial processes were benchmarked against similar state of the art processes • Technologies for the Army processes were identified and examined to determine the costs and benefits of implementation • A software tool was designed to provide strategies to reduce harmful emissions in Army industrial buildings • System optimization control strategies were developed to optimize heating, cooling and ventilation loads • Studies of four Army facilities were conducted to demonstrate the benefits in efficiency improvements and energy savings that can be realized by adopting the technologies, tools, and strategies • The project proceeded along three separate lines: • An understanding of major Army industrial processes in terms of how they operate and how they consume energy was developed • Through research, site visits, and consultations, a consensus in defining the current state of the art of technologies related to the Army processes was developed • Data collection and analysis of contaminant emissions and ventilation within Army facilities was conducted in order to develop a better understanding of building process exhaust and thermodynamic principles
