Building Controls & Automation in Aliso Viejo, CA

In the business parks along Aliso Creek and Enterprise, buildings arrive with capable controls and the problem is keeping them honest. Sensors drift, schedules get overridden, and vendors' trend logs fill with data no one reads. We run an analytic pass over trends, flag simultaneous heating and cooling, and fix the sequences, which usually recovers efficiency without touching mechanical equipment. We deliver a written findings sheet with prioritized fixes, so a building manager can assign work without needing to interpret controls screens.

Modern business parks and mixed-use retail/office development.

How building controls & automation work plays out in Aliso Viejo

Aliso Viejo may have the highest proportion of real building automation of any city in south Orange County. The office campuses along Enterprise and Pacific Park Drive, the mid-rise buildings near the 73, the university, the hotel and the larger Town Center office blocks were built in the era when DDC systems became standard, and most of them still run some version of their original front end. That is both the opportunity and the problem: there is a system that could run the building well, and it has been drifting for fifteen or twenty years.

What we find in these systems follows a pattern. Schedules reflect a tenant who left years ago. Overrides placed during a long-ago complaint are still active. Supply air and chilled water reset sequences were disabled to stop a nuisance alarm. Outside air sensors read several degrees off and the economizers follow them. The front end runs on an unsupported operating system on a computer in a closet. None of this shows up as a failure; it shows up as a utility bill that is higher than a building of that age should produce and comfort complaints that never fully resolve.

Controls work here ranges from a verification visit, where we test sensors against a reference, stroke dampers and valves, review schedules and trends, and document the findings, to upgrades of the front end or integration of new rooftop and VRF equipment into the existing system. Smaller buildings and tenants with standalone thermostats get networked commercial thermostats with remote visibility. All configurations are recorded in the DaVinci Portal. The building controls service page describes what a verification includes.

Aliso Viejo's climate and what it does to this equipment

Aliso Viejo has moderate temperatures with some coastal influence; cooling load is significant on summer afternoons but corrosion pressure is lower than at the beach.

Where this work shows up in Aliso Viejo
  • Aliso Viejo Town Center
    Mixed-use retail, restaurants, and offices.
  • Business parks along Aliso Creek and Enterprise
    Corporate and technology tenants.
  • Medical and life-science buildings
    Temperature-sensitive spaces and storage.
  • University and school facilities

What this service covers
  • Schedule, setpoint, and sequence review across rooftop and central equipment
  • Sensor calibration and economizer verification
  • Alarm and trend setup so problems surface early
  • Programmable and networked thermostat installation
What a building controls & automation visit includes, and the problems we most often find
  1. Inventory controllers, thermostats, and any building automation system
  2. Compare schedules and setpoints to how the building is actually used
  3. Verify sensors, actuators, and economizer logic against measured conditions
  4. Correct overrides, sequences, and alarms; document the changes
  5. 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 Aliso Viejo: questions we get

Our Aliso Viejo building automation system runs on a very old computer nobody wants to touch. What are the options?

Several, and none require ripping out the field controllers. The front end can often be migrated to a supported platform while keeping the existing controllers and wiring, or a gateway can bring the existing system into a modern web-based interface. The right path depends on the controller brand and protocol. We document what is installed first and then recommend the smallest upgrade that gives you a supported, visible system.

Tenants in our Aliso Viejo campus building complain some zones are cold while the chiller is running hard. Is that a controls problem?

Very likely. In VAV buildings, overcooled zones with the plant working hard points to supply air temperature reset that is disabled, VAV boxes with failed dampers or stuck reheat valves, or sensors reading wrong. A verification visit traces the sequence from the thermostat to the box to the air handler and plant, and the fix is usually a combination of calibration, repairs to a few boxes, and restoring the reset logic.

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.
