Abstract: This study was conducted as part of California State University of Long Beach (CSULB) Research Foundation project tittle “Internet of Things (IoT) and Ubiquitous Sensing in University Building Energy Management: Design, Optimization and Technology Demonstration” funded by the California Energy Commission (CEC) EEETD grant and led by Dr. Massoud Nazari. The Emerging Energy Efficient Technology Demonstrations (EEETD) grant of the CEC is aimed to demonstrate and market the deployment of innovative pre-commercial energy efficiency technologies in existing buildings to promote early adoption of energy efficiency systems that will reduce energy consumption as well as costs for the building owner. Despite the technological advancements for building management systems the actual market penetration is still relatively small in the commercial sector. One of the reasons for not investing on upgrades includes informational awareness. In the hopes to aid in that particular aspect, the following study provides a breakdown of the process for the commissioning of the new management system and demonstrates the scalability of the overall project by first focusing on the existing building such as identifying the building’s energy end uses and circuit configuration for lighting, HVAC, and plug loads. Second, it details the customization for the new EMS, and the interoperability of the new smart devices and network architecture.
