Building Automation Engineering in El Segundo, CA

The South Bay's aerospace and industrial powerhouse — long home to Northrop Grumman, Raytheon, and a Chevron refinery, now joined by SpaceX's Hawthorne neighbor and a growing tech presence — El Segundo sits directly under LAX flight paths. Heavy industrial, defense, and aviation define its engineering demand, with coastal seismicity and refinery-adjacent safety rules.

What we engineer

Building automation and controls design: BACnet/IP and MS/TP network architecture per ASHRAE Standard 135, DDC controller layouts, sequences of operation written to ASHRAE Guideline 36, HVAC integration (chillers, boilers, VAV, VRF), lighting/HVAC integration, and energy metering per ASHRAE 90.1 Section 8.4. Fault detection and diagnostics (FDD) for air handlers and plants, plus demand-response-ready sequences per OpenADR.

Code compliance that passes

ASHRAE 90.1 and IECC C403/C404/C405 control mandates — automatic shutoff, occupancy and daylighting sensing, demand-controlled ventilation — plus IECC C408 commissioning documentation and Title 24 acceptance testing where required. BACnet Secure Connect (BACnet/SC) with TLS encryption for cybersecurity on every network we design.

Backed by licensed PEs

All building automation engineering is backed by Apex Grid Engineering: 10+ PEs licensed across 49 states, 20+ engineers, 15+ years of plan sets that pass plan check.
