Building Controls & Automation in San Bernardino, CA
Public buildings in San Bernardino often have automation systems that are partially functional: some points work, some sensors drift, and some schedules were overridden years ago. We audit what is actually controlling equipment, correct sensor and damper issues, update schedules, and document sequences. When smoke events make outdoor air unsuitable, controls should also let operators respond intentionally rather than discovering the problem through complaints.
The county seat, with downtown government buildings, hospitals, rail-served logistics, and aging mixed-use property stock that works hard through hot, smoggy summers.

How building controls & automation work plays out in San Bernardino
The controls systems in San Bernardino's public buildings are often the most neglected asset on the property. A county office building may have a building automation system installed during a renovation, partly integrated with older pneumatic or stand-alone controls that were never fully replaced. Over the years, points stop reporting, sensors drift, schedules get overridden for a one-time event and never restored, and the operator workstation ends up showing a picture of the building that no longer matches reality. Meanwhile the rooftop units run on whatever the last override said, which in a cooling-dominated climate means a lot of hours of mechanical cooling that the weather did not require.
Our controls work begins with an audit of what is actually controlling what. We verify sensor readings against calibrated instruments, test economizer dampers and actuators, check outdoor air lockouts, and compare programmed schedules with real occupancy at courts, clinics, offices, and school buildings. In this city the outdoor air strategy needs one more layer: during smoke events, operators need a way to lock out economizers intentionally and bring them back when air quality clears. We make sure that control exists and that the facilities team knows how to use it.
The deliverable is a documented sequence of operations, corrected setpoints and schedules, and a list of failed points with a repair plan. For agencies, that documentation also supports energy reporting and justifies controls upgrades in a capital request. The government buildings sector page covers how controls fit into a public facility's long equipment life cycle.
San Bernardino's climate and what it does to this equipment
San Bernardino sits at the foot of the mountains in a pocket where hot, polluted air often collects. Summer highs are among the highest in the region, and smog and fine particulate coat coils and clog filters faster than in coastal areas. Santa Ana winds in fall and winter bring heat, dust, and elevated fire danger, and wildfire smoke from nearby mountains is a recurring factor, sometimes closing windows of acceptable outdoor air for economizer use. Cold winter nights give heating real work to do. Equipment here is hit by every factor at once: high ambient, dirty air, and wide seasonal range.

What a building controls & automation visit includes, and the problems we most often find
- Inventory controllers, thermostats, and any building automation system
- Compare schedules and setpoints to how the building is actually used
- Verify sensors, actuators, and economizer logic against measured conditions
- Correct overrides, sequences, and alarms; document the changes
- Review trends after adjustment to confirm savings and stability
- Schedules left at default so equipment runs when nobody is there
- Equipment overridden manually and never returned to automatic
- Drifting or miswired sensors producing comfort complaints
- Economizers that never actually modulate
Building Controls & Automation in San Bernardino: questions we get
Our county building's automation system shows everything normal, but tenants complain constantly. Why?
Because the system is reporting what its sensors say, and the sensors may be wrong, disconnected, or reading a location that does not represent the space. Drifted space sensors, failed damper actuators that still report a commanded position, and schedules overridden long ago are common on older public building systems. A controls audit compares what the workstation shows with measured conditions in the space and at the equipment, then corrects the points that are lying.
Should economizers be used at all in San Bernardino given the heat and the smoke?
Yes, but with correct lockouts. There are many hours in spring, fall, and overnight when outdoor air is cool enough to carry part of the load, and a working economizer saves real energy. The failures come from dampers stuck open in summer heat and from economizers pulling smoke during fire events. Properly set high-limit lockouts, verified actuators, and a documented procedure for manual lockout during poor air quality make them an asset rather than a liability.
Do you install building automation systems?
We install and service thermostats and controls on rooftop and mechanical equipment, and work with larger automation systems on a project basis.
Can better controls really cut energy use?
Often. Correct schedules, setpoints, and economizer operation are among the cheapest efficiency gains in an existing building.
Can you connect to our existing system?
In most cases. Send us what is installed and we will confirm the integration approach.
