“Climate Change is Global Health Issue.”
NetZero 2025
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

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.

UCSF – Current State
BMS Profile West Campus
Control system is being retired by the manufacture
Network controllers do not support modern security requirements .
Proprietary field bus communication
Network and field level controllers need to be replaced simultaneously.
Sole sourced – no competitive bidding

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 !
