Commercial Building Management System (BMS) for Gree HVAC in Orange, CA

What we deliver for commercial buildings in Orange

Our BMS solutions integrate Gree HVAC assets into a single pane of glass so your team can monitor, control, and optimize comfort and energy in real time. We engineer to your building’s purpose—offices, retail, education, healthcare, hospitality, or industrial—so you get stable temperatures, proven indoor air quality, and lower operating costs.

• Gree VRF (GMV) and ducted systems integration
• BACnet/IP, BACnet MS/TP, and Modbus RTU/TCP connectivity
• Enterprise dashboards, alarms, trends, and reports
• Demand-controlled ventilation with CO2 and IAQ sensors
• Energy optimization, scheduling, and setpoint strategies
• Commissioning, training, and ongoing service

Deep expertise in Gree systems

We are factory-trained by Gree (China) and skilled with Gree VRF GMV, heat recovery, and ducted air handlers. Whether your project requires new controls architecture or a retrofit with gateways, we map points accurately, validate performance, and ensure reliable communications between the Gree equipment and your BMS.

Our team is also factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), and Hier (China), which strengthens our multi-brand understanding while keeping your Gree system the focus of integration.

Controls, protocols, and cybersecurity

We design robust controls networks that prioritize uptime and data integrity. From controller selection and panel fabrication to graphics and trending, every layer is built for clarity and serviceability.

• Open protocols: BACnet/IP, BACnet MS/TP, Modbus RTU/TCP
• Gateway configuration for Gree VRF to BMS
• Network segmentation and user access best practices
• Time-stamped alarms and fault diagnostics for rapid response

Compliance and standards for California buildings

Our engineering approach aligns with California Title 24, CALGreen, and ASHRAE 62.1/55/90.1 requirements. We implement sequences of operation that pass plan check and deliver verifiable outcomes—comfort, air quality, and energy efficiency—backed by commissioning and trend data.

• Title 24 Part 6 sequences and documentation
• Trend logs to validate ventilation and economizer operation
• Optimized scheduling, setback, and demand response support

Healthy indoor air is our mission

We believe healthy buildings support healthy lives. Our BMS strategies improve IAQ through CO2-based ventilation, filtration monitoring, and integration of IAQ sensors (PM2.5, VOC, humidity) where required. We coordinate economizers, ERVs, and Gree equipment to maintain fresh air without sacrificing energy performance.
