Utility and state program administrators have long used proprietary software and communication protocols to manage and process data collected by home performance contractors. This has typically resulted in higher costs of doing business (for programs and contractors), vendor lock-in, and less-efficient management processes, especially if the data were not standardized. It has also greatly limited the ability to track and aggregate energy savings across programs and states, because data are being collected in different formats and are not easily exchangeable. In larger programs that serve hundreds of homes per year, thousands of data points may be collected, representing a significant cost to the industry if data cannot be easily aggregated, shared, and analyzed. Without data standardization, administration tasks such as verifying, sharing, and processing data become costly and labor intensive.
