Anaheim Needs, Codes, and Climate

Anaheim’s mix of offices, entertainment venues, hospitality, and industrial spaces demands dependable controls that balance comfort, IAQ, and efficiency. We design with Southern California climate zones and local permitting in mind, align with Title 24 requirements, and support utility incentive pathways where available. Our team implements sequences that reduce peak demand, stabilize humidity, and maintain consistent temperatures across diverse occupancy profiles.

• Site survey: as‑built review, controls audit, network assessment, and point list validation.
• Design: sequences of operation, network architecture, controller selection, and submittals.
• Implementation: clean installation, labeling, and documentation with safety and coordination.
• Commissioning: point checkout, graphics verification, alarm tuning, and functional testing.
• Training and handoff: role‑based training, O&M binders, and remote access setup.
• Support: proactive maintenance, trending reviews, and continuous optimization.
