Modernize Your Building Controls Without Starting Over
Your building automation system doesn't have to be torn out to be improved. At Encode Corporation, we work with what you have — assessing your existing controls, identifying what still performs, and building a retrofit plan that moves you forward without unnecessary replacement. We've been doing this kind of work in Montana since 1978, and we understand that facility managers and property owners need a clear scope, a realistic timeline, and a system that actually works when the project is done.
Retrofit or Replace? Here's How We Help You Decide
Most buildings don't need a full BAS replacement — they need a smarter upgrade. The question isn't whether your old system is outdated; it's whether its core infrastructure can be extended to meet current performance and integration requirements. We evaluate your existing equipment, control devices, and communication architecture before recommending any course of action. If components can be retained and brought into a modern controls framework, we'll tell you. If replacement is the more cost-effective path, we'll tell you that too. You won't get a recommendation built around what's easiest to sell.
What a Controls Retrofit with Encode Looks Like
Assessment and Scope Definition
Before any work begins, we conduct a thorough evaluation of your existing building automation system — controllers, sensors, communication protocols, and integration points. This is where scope gets defined, not discovered midway through a project. You'll know what's being retained, what's being replaced, and what the finished system will be capable of before we start.
Legacy System Integration
Older HVAC equipment and control systems weren't designed to communicate with modern BAS platforms, but that doesn't mean they can't. BACnet and related open protocols are built specifically to bridge equipment across generations and manufacturers. We configure your retrofit to eliminate isolated equipment islands and give you unified visibility and control over systems that previously couldn't talk to each other.
Phased Modernization
Not every retrofit has to happen at once. We design upgrade paths that can be executed in phases — prioritizing the systems with the greatest operational impact first, then expanding from there. This approach distributes cost over time, reduces disruption to your facility, and lets each phase be fully commissioned before the next begins.
Commissioning and Documentation
A retrofit isn't complete when the wiring is done. We commission every system we install — verifying sequences of operation, testing communication between devices, and confirming the system performs as specified. We also provide documentation so your facility team understands what was installed, how it's configured, and how to work with it going forward.
Why Interoperability Is the Core Challenge in BAS Retrofits
The most common problem we encounter in retrofit projects isn't aging hardware — it's equipment that can't communicate. Facilities accumulate HVAC systems, controls, and sensors from different manufacturers and different eras, and without a unifying integration layer, each one operates as its own island. Energy data stays siloed. Fault detection is manual. Scheduling has to be managed system by system. A well-executed building automation retrofit solves this by establishing a common communication backbone — typically BACnet or a compatible open protocol — that allows legacy and new equipment to share data and respond to centralized commands. The result is fewer blind spots, more usable control, and a facility that behaves like a coordinated system rather than a collection of independent components.
Who We Work With on Retrofit and Integration Projects
Encode serves commercial, industrial, and institutional facilities across Montana. Our retrofit and integration work spans a wide range of building types and operational profiles.
- Office buildings and multi-tenant commercial properties managing aging pneumatic or early digital controls
- Healthcare and institutional facilities requiring reliable uptime and documented commissioning
- Industrial operations with process HVAC and environmental controls that need to integrate with broader facility systems
- Property managers and facility directors overseeing multiple buildings who need consistent, centralized visibility
- Organizations that have already invested in new HVAC equipment but are still running disconnected controls
If your building has a controls problem — whether it's a legacy BAS that can't keep up, equipment that won't communicate, or a system that was never properly commissioned — we can assess it and build a path forward.
Retrofit & Integration — Frequently Asked Questions
Does my Billings building's automation system need full replacement, or can it be retrofitted?
Most buildings need a smarter upgrade, not a full replacement. We evaluate your existing controllers, sensors, and communication architecture before recommending either path.What's the biggest challenge in a BAS retrofit for older Billings buildings?
Interoperability — equipment from different manufacturers and eras that can't communicate with each other. A well-executed retrofit establishes a common protocol, usually BACnet, so everything can share data.Can a Billings building automation retrofit be done in phases instead of all at once?
Yes. We design phased upgrade paths that prioritize the highest-impact systems first, spreading cost over time and reducing disruption.What happens after a controls retrofit is installed in a Billings facility?
We commission every system — verifying sequences, testing communication between devices — and provide documentation so your team understands the configuration going forward.What kinds of Billings-area buildings benefit most from a controls retrofit?
Office buildings and multi-tenant properties running aging pneumatic or early digital controls, healthcare and institutional facilities, and industrial sites with disconnected legacy systems.
Ready to Modernize Your Building Controls?
If your facility is running on aging controls, disconnected systems, or a BAS that no longer meets your operational needs, the right next step is a site assessment. We'll evaluate what you have, define a realistic scope, and give you a clear picture of what a retrofit or integration project would look like — before you commit to anything.
