Benefits of the Technology • Helps identify buildings for improvement efforts • Can explore a portfolio of buildings • Building models can be used for automated fault detection and diagnostics • Up to 53% average cost savings compared to traditional Do. D audits • Payback of less than 1 week 7
Technology Success Stories • Technology has been successfully demonstrated by ESTCP at: • • • Air Force Academy in Colorado Spring, CO Fort Bliss in El Paso, TX Fort Jackson in Columbia, SC Tyndall Air Force Base in Panama City, FL Naval Support Activity Monterey (NSAM) in Monterey, CA 8
Potential Challenges and Solutions • IT Security • The software has not completed the Do. D IT security process, so the installation would need to pursue this in order to install it on Do. D servers. Alternatively, the audit could be conducted by contractors who install the software on their own system. • Data Ownership • If this audit is conducted by contractors, the contract will need to address the issue of data ownership and control. To achieve the long-term portfolio-wide benefits offered by this software, the installation would need to secure ownership of the collected building data as well as the analysis results. • Training • Software use requires a few days of training. Any procurement discussion should involve the cost of training auditors. 9
Sample Financial Considerations From ESTCP Demonstration: • Assumptions: • Labor cost: $120/hour • Simple payback period <1 week based on savings from identified improvements 10
Bottom Line • Pros • • Helps identify buildings for improvement efforts Cost savings over traditional audits Portfolio-level view Building model reuse • Cons • Training cost • Not yet certified for use of Do. D servers • Data ownership challenge 11
