This Small Business Innovation Research (SBIR) Phase II project will further develop the IBUCS' Utility Accountant electrical load disaggregation system and conduct performance trials in small commercial settings. Utility ratepayers need granular information to more effectively identify and mitigate inefficient appliances and activities. The new generation of smart electric meters currently being deployed for automated reading and time of use pricing are not be able to provide this level of detail. The signal processing algorithms evaluated during the Phase I study accurately isolate and quantify the power used by individual appliances from the aggregate power signal of the many appliances present on a leg or circuit. In the proposed project, additional enhancements will be made to the load disaggregation algorithm that will significantly improve system accuracy and reliability. Ratepayers will access a secure webpage to view their cost to operate specific appliances in their building or groups of buildings. The granular perspective provided will enable end-users to (1) calculate their own investment return periods for equipment repairs and upgrades, (2) develop data driven best practices for energy conservation, and (3) ensure that cost reductions are maintained over the long term.The broader impact will occur when the technology is deployed throughout the residential and commercial segments as part of a new generation of smart meters. Commercially-available systems that directly monitor multiple specific loads are more expensive by an order of magnitude and inherently more difficult to install and maintain. Providing appliance specific load information has the potential to transform ratepayers' ability to conserve energy. The intended outcome of this Phase II project is to create an easy-to-use tool that will continually educate small business or franchise operators to reduce energy consumption. Nationally, Quick Serve businesses (i.e. fast-food restaurants, gas stations, and minimarts) account for ~10% of commercial buildings but are generally underserved by energy management companies due to their small size. IBUCS will provide a value-added service to the property manager through an energy management company that serves this segment.

这个小企业创新研究（SBIR）第二阶段项目将进一步开发IBUCS的公用事业会计电力负荷分解系统，并在小型商业环境中进行性能试验。公用事业纳税人需要精细的信息来更有效地识别和减少低效的设备和活动。目前正在部署的新一代智能电表的自动阅读和使用时间定价是不能够提供这种级别的细节。在第一阶段研究期间评估的信号处理算法准确地将单个电器使用的功率与支路或电路上存在的许多电器的总功率信号隔离并量化。在拟议的项目中，将进一步增强负荷分解算法，这将大大提高系统的准确性和可靠性。纳税人将访问一个安全的网页，以查看他们的成本，以操作特定的电器在他们的建筑物或建筑群。提供的细粒度视角将使最终用户能够（1）计算自己的设备维修和升级投资回报期，（2）开发数据驱动的节能最佳实践，（3）确保长期保持成本降低。当该技术作为新一代智能电表的一部分部署在整个住宅和商业领域时，将产生更广泛的影响。直接监测多个特定负载的市售系统更昂贵一个数量级，并且固有地更难以安装和维护。提供电器特定负载信息有可能改变纳税人节约能源的能力。第二阶段项目的预期成果是创建一个易于使用的工具，不断教育小企业或特许经营商减少能源消耗。在全国范围内，快速服务企业（即快餐店，加油站和小型超市）占商业建筑的10%左右，但由于规模较小，能源管理公司通常服务不足。IBUCS将通过一家服务于这一领域的能源管理公司为物业经理提供增值服务。
