“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

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


Parnassus Campus




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


Mission Bay Campus




BMS Profile East Campus

Legacy network controllers

Network controllers do not support modern security requirements .

Distributed building servers – Microsoft XP

Lon field bus communication - Not proprietary

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 !
