DDC Controls and Integration

Commercial Building Automation Systems

See your entire building on one screen. We design, install, and integrate DDC building automation across Dallas-Fort Worth, giving you control, visibility, and energy savings from a single dashboard.

Building Automation

Smart Control for Every System in Your Building

A building automation system, or BAS, connects your HVAC, mechanical, and related building systems to a central platform you can see and control from anywhere. Instead of walking the building to adjust thermostats and check equipment, your facility team monitors air handlers, chillers, boilers, pumps, and zones from one dashboard, with real-time data on every point.

We build these systems on direct digital control, or DDC, where microprocessor-based controllers manage equipment precisely and consistently. DDC does not just switch equipment on and off. It modulates dampers, valves, and variable speed drives to hold exact conditions, sequences equipment for efficiency, and logs everything so patterns become visible over time. The result is tighter comfort, lower energy use, and fewer surprises.

Whether you are automating a single building or standardizing controls across a portfolio, we design open, integrated systems that tie your equipment together. That includes new construction, retrofits of aging pneumatic or legacy controls, and integration with the VRF systems and chiller plants we already service.

Capabilities

What a Building Automation System Does for You

Four capabilities that turn scattered equipment into one manageable system.

Centralized Control
Monitor and command every system from one dashboard. Adjust setpoints, schedules, and sequences building-wide without walking the floors.
Energy Optimization
Optimized schedules, setpoint resets, economizer control, and equipment staging trim energy waste without sacrificing comfort.
Remote Access and Alarms
Check your building from a laptop or phone, and get alarms the moment something drifts out of range, so you act before tenants notice.
Trending and Fault Detection
Historical trends turn raw data into insight, revealing failing equipment, wasted energy, and comfort problems long before a breakdown.
What We Integrate

Systems We Connect Under One Platform

We bring your mechanical systems together, whatever mix of equipment your building runs.

Air handling units and VAV boxes
Rooftop units and packaged equipment
Chiller plants and cooling towers
Boilers and hydronic systems
Pumps and variable speed drives
Zone temperature and humidity control
Energy metering and demand monitoring
VRF systems and specialty equipment
Open Protocols

Built Open, Not Locked In

Proprietary controls trap you with one vendor. We build systems you actually own.

Our Process

How We Deliver a Building Automation Project

From assessment through optimization, engineered around how your building actually runs.

1
Assess and Design
We evaluate your equipment, existing controls, and goals, then design a system and points list that fits your building and budget.
2
Install or Retrofit
We install DDC controllers, sensors, and network wiring, replacing pneumatic or legacy controls without ripping out working equipment.
3
Program and Graphics
We build control sequences, alarms, schedules, and custom graphics so your team sees the building the way it actually works.
4
Commission and Optimize
We test every point, tune sequences for efficiency, train your staff, and keep optimizing through ongoing service.

Common Questions

Building Automation FAQ

What is a building automation system?
A building automation system (BAS) connects your HVAC and mechanical equipment to a central platform for monitoring and control. Instead of adjusting each thermostat or checking each unit by hand, your team sees the whole building on one dashboard, sets schedules and setpoints, and receives alarms when something needs attention.
What is DDC control?
DDC stands for direct digital control. It uses microprocessor-based controllers to manage equipment precisely, modulating dampers, valves, and drives rather than simply switching things on and off. DDC holds tighter conditions, sequences equipment efficiently, and logs data so you can see how your building performs over time.
Can you upgrade our controls without replacing all our equipment?
Yes. We retrofit pneumatic and legacy controls with modern DDC while keeping your working mechanical equipment in place. We phase the work so your building keeps operating, and we integrate the new controls with existing chillers, boilers, air handlers, and rooftop units instead of forcing a full replacement.
Will a building automation system lock us into one vendor?
Not the way we build them. We favor open protocols so you are not tied to a single manufacturer's parts and pricing. That lets you integrate mixed equipment, add to the system freely, and choose who services it, which lowers your total cost of ownership over the life of the system.
Can we monitor and control the building remotely?
Yes. A modern BAS lets your team view live conditions, adjust setpoints and schedules, and respond to alarms from a laptop or phone. You can catch a drifting space temperature or a failing unit before tenants notice, and manage multiple buildings from one place.
How does a building automation system save energy?
A BAS trims waste through optimized schedules, setpoint resets, economizer and free-cooling control, and smart equipment staging, so systems run only as hard as they need to. Trending and fault detection also surface waste and failing equipment early, which protects both efficiency and your maintenance budget.
