This presentation from Kenny Seeton, Central Plant Manager at California State University – Dominguez Hills, covers the opportunities and benefits of occupancy-based unified controls using Welch Hall as a case study.  Kenny discusses the basis of controls design process, matching lighting and HVAC zones, and energy savings opportunities of integrating lighting with a building automation system.

This class examines examples of integrating lighting controls with other building controls, primarily HVAC. Rather than presenting a set of established best practices, it reviews a few notable case studies of commercial and institutional buildings where integration has been both successful and challenging. Presenters describe the design process, how key decision points were identified, and how issues were resolved. They also cover Owners Project Requirements, Basis of Design, and Sequence of Operations, and report on commissioning and post occupancy evaluations.

GSA’s Green Proving Ground program recently assessed the potential of wireless sensor technology to provide a cost-effective and facilities-friendly way of helping data center operators visualize and implement system changes that reduce overall energy consumption. Findings include significant cost savings, as well as a substantial reduction in cooling load and CO2 emissions.  Sensors utilizing a wireless mesh network and data management software to capture and graphically display real time conditions for energy optimization were installed in a demonstration project.

System Program Manuals and Assessment Methods:  LBNL researchers worked with three sets of Utilities to identify and develop validated protocols for specific building systems. The selected systems were: automated shading integrated with lighting and HVAC controls (working with ComEd in Chicago), task/ambient lighting retrofit integrated with plug load occupancy controls (working with California POUs, NCPA and SCPPA), and workstation-specific lighting with daylight dimming systems (working with Xcel Energy in Colorado and Minnesota).
