Data Acquisition Methods: Lessons Learned from Deployment of Cloud HVAC Analytics at UCSB Tuesday, June 27 th 2017 Michael Georgescu (Ecorithm) Jordan Sager (UCSB) California Higher Education & Sustainability Conference (CHESC 2017)
Motivation & Project Background Today’s talk: • § Geared to FM teams interested in or at early stages of FDD implementation This effort: • § Mid 2015 - late 2016: UCSB FM deploys analytics software on two campus buildings as part of MBCx project § Early 2017 - present: project extends to two laboratory buildings with bandwidth for full campus rollout § Important aspects of the project are: • Integration approach & system architecture • Scalability • Persistence of savings vs. traditional retro-Cx projects • Cost-effectiveness & time-effectiveness Tuesday, June 27, 2017 California Higher Education & Sustainability Conference (CHESC 2017) 2
Building Analytics at UCSB • Deployment of monitoring-based commissioning through advanced analytics of trended BMS data • At the outset: § BAS integration § Analytics § Reporting • Moving forward: § Mechanical drawings/schedules § Spatial data § Work order system interface § Rethinking data acquisition Tuesday, June 27, 2017 California Higher Education & Sustainability Conference (CHESC 2017) 3
Education and Social Science Building • ESSB buildings selected for initial deployment due to a history of temperature complaints • 5,686 points trending on 5-minute intervals using native functionality in BMS and stored in cloud database • Advanced analytics software interacting with database to monitor building plant, AHU (6), and terminal units (175) for MBCx project Tuesday, June 27, 2017 California Higher Education & Sustainability Conference (CHESC 2017) 4

MBCx Results • 1 st Year Outcomes: § Frequency of new issues lowered by 50% § Occupant comfort improved by 45% § HVAC Maintenance requests lowered by 60% • Approved incentive amount of $40,289 with energy savings of 137,368 kWh & 7,321 therms • Data integration and consolidation facilitated easy information access • Feedback to Ecorithm helped improve analytics, FDD definitions and workflow integration… Tuesday, June 27, 2017 California Higher Education & Sustainability Conference (CHESC 2017) 6
Energy Efficient Operations •“Properly applied off the shelf or state-of-the- A national laboratory of the U.S. Department of Energy Office of Energy Efficiency & Renewable Energy National Renewable Energy Laboratory Innovation for Our Energy Future art technologies are available to Lessons Learned from Technical Report achieve low-energy buildings. However, these NREL/TP-550-37542 Case Studies of Six June 2006 High-Performance Buildings strategies must be applied together” P. Torcellini, S. Pless, M. Deru, B. Griffith, N. Long, and R. Judkoff NEED FOR INTEGRATION OF BEST-IN- CLASS COMPONENTS •“There was often a lack of software to allow the technologies to work well together” NREL is operated by Midwest Research Institute !

Moving Forward • As building managers and operators, we know a building’s energy systems can become inefficient quickly! • Lessons learned at UCSB in sustaining performance: § Defining a plan for collecting and integrating BMS, energy, and other data sources enables analytics to be applied to everyday operations § Involving campus stake holders (FM, IT, Occ.) ensured that all approvals are met cost effectively and without delays • Making analytics mainstream: we hope to uncover additional opportunities and improve building performance as adoption grows Tuesday, June 27, 2017 California Higher Education & Sustainability Conference (CHESC 2017) 15
