1 Modernizing Control Systems for Campuses APPA 2018 Presented by: James Comte, Commissioning and Controls Manager University of California, San Francisco In November 2013, President Janet Napolitano announced the Carbon Neutrality Initiative, which commits UC to emitting net zero greenhouse gases from its buildings and vehicle fleet by 2025, something no other major university system has done Climate Change is Global Health Issue.

2 How Buildings Affect the Environment Energy Use Per the U.S. Green Building Council (USGBC), buildings account for an average of 41% of the world s energy use. In the United States, buildings are responsible for 73% of the country s electricity consumption. So what is it that s taking up so much energy? Well, it s many things. A building s lighting system, heating and cooling system and outlet use all contribute. Impact on the Air Buildings are responsible for 38% of all CO2 emissions. Water Use Buildings are responsible for not just a large percentage of the world s water use, but a large percentage of wasted water as well. It s estimated that buildings use 13.6% of all potable water, which is roughly 15 trillion gallons of water per year. 3 UCSF as a World Leader Advancing Health Worldwide Carbon Neutrality and Sustainable Practices 4 2 [footer text here]

3 Agenda Introduction to UCSF - Our Mission - Current State The Need for Modern Building Automation Roadmap for Retrofits - Scope Development - Project Delivery - Commissioning and Turnover Pilot Project PSB (Parnassus Services Building) - Mechanical - System Cutover and Verification 5 UCSF Current State Campus Description, West Campus 27 buildings 3,134,000 sq. ft. East Campus 22 buildings 3,125,600 sq. ft. New Construction Adding 3-5 M sq. ft. Control systems range from pneumatic to DDC Legacy and proprietary control systems Multiple controls vendors/systems throughout UCSF 6 3 [footer text here]

6 The Challenge! Modernizing Building Controls Many campuses are faced with aging and/or obsolete controls systems that present many challenges. Cybersecurity risk Maintenance cost Meeting sustainability and energy goals Replacing control systems present many challenges as well. Expensive to replace Buildings are occupied Retro-fitting building controls has additional challenges High cost due to sole-sourcing Choosing controls that won t go obsolete in the near future. One chance to get it right! 11 Campus Architecture IOT/OT/Data Strategy Energy Department.
