The Joint Systems Manufacturing Center, also known as the Lima Army Tank Plant (LATP), is a tank plant located in Lima, Ohio. It is a government-owned, contractor-operated facility currently operated by General Dynamics Land Systems. Built in the 1940’s, this premiere industrial facility is capable of manufacturing, repairing, refurbishing, and testing a full spectrum of combat vehicles and defense systems.
As the largest energy consumer in the United States, the U.S. federal government is working hard to reduce energy usage in its facility portfolio. Similarly, the Joint Systems Manufacturing Center sought to reduce the energy consumed at its campus in Lima, OH. The objective for this project was to source and address areas that were operating inefficiently, and Siemens Government Technologies was enlisted to design and implement energy savings projects involving all forms of energy consumption. Facility lighting was included in the scope of this project as it presents a significant opportunity to reduce both energy consumption and maintenance expenses. Additionally, it was generally agreed upon that the entire complex needed improved lighting quality.
Siemens Government Technologies partnered with lighting specialist Eco Engineering to audit, design, and implement phases of the lighting system. In this project, installation was challenging given the need to upgrade lighting systems in an active production environment. Our design for the energy-efficient lighting replacement system primarily incorporated LED high bay fixtures. These fixtures were designed to better distribute light at a lower operating cost while utilizing an advanced lighting control system with wireless intelligent sensors. The sensors were equipped to gather, interpret, and distribute lighting & energy usage data to a central control module. The control system constructed specific light profiles for each fixture in each work area and allowed for local and remote access for altering the lighting and energy profiles.
The upgraded lighting system delivered exceptional results in terms of energy savings. The system itself saved enough energy to be equivalent to removing 15.5 million pounds of carbon dioxide emissions from the atmosphere.
- Annual Demand Reduction: >17,000 kW
- Estimated Annual Consumption Savings: 10,135,223
The financial benefits of the new lighting system are significant and will save hundreds of thousands of dollars every year.
- $48,142 in reduced energy costs
- $5,718 reduced maintenance cost
- Total annual energy savings $577,000
