Platforms & Capabilities
Every Major BAS Platform. One Team.
Niagara Framework (N4)
Tridium Niagara N4 programming, module development, and custom widget creation. The most widely deployed open-platform BAS in commercial buildings.
Certified Niagara programmers. JACE and Supervisor configuration included.
Johnson Controls Facility Explorer
Programming and commissioning for JCI's Facility Explorer platform — the authorized system integrator path for Johnson Controls BAS. Custom sequences, alarm routing, and trend configuration across FX controller hardware.
MJI is a JCI Authorized System Integrator (ASI). Facility Explorer is the correct JCI platform for independent integrators.
All Platforms
MJI integrates with all major commercial BAS manufacturers — not just the platforms we lead with. Honeywell, Daikin, Carrier CCN, Trane, and others are supported through open-protocol BACnet integration and platform-agnostic programming.
BACnet-native integration. Works alongside existing equipment and front-ends without proprietary lock-in.
Custom Ladder Logic & Structured Text
Low-level PLC programming when the application demands precision — combustion control, complex process logic, or tightly sequenced mechanical systems.
IEC 61131-3 standard. AB, Siemens, and Beckhoff platforms supported.
Sequence of Operations Authoring
We write the spec and then build exactly to it — no ambiguity, no shortcuts. SOO documents that are clear enough for any qualified technician to follow.
Deliverable becomes the handoff document for your operations team.
ASHRAE Guideline 36
Standardized high-performance sequences for VAV systems, AHUs, and chilled/hot water plants. G36 implementation reduces HVAC energy use by an average of 30% versus conventional sequences — without replacing any equipment.
Open standard, platform-agnostic. Produces the trend data LL97 reporting and PSEG rebate applications require.
ASHRAE 62.1 / Demand Control Ventilation
CO2-based ventilation control that scales outdoor air delivery to actual occupancy — not worst-case assumptions. Reduces heating and cooling energy while keeping every zone properly ventilated. Required by ASHRAE 90.1 for qualifying high-occupancy spaces.
DCV can reduce HVAC energy 9–33% vs. fixed OA systems. MJI handles sensor placement, BAS programming, and commissioning documentation. Learn about ASHRAE 62.1 →
Fault Detection & Diagnostics
Automated monitoring that flags stuck dampers, failed actuators, sensor drift, and off-sequence equipment — before issues affect comfort or show up on an energy bill. Built into G36 sequences and also available as a standalone BAS layer.
Catches issues weeks before they escalate. Reduces reactive service calls and extends equipment life.
Who It's For
Built for Teams Who Demand Precision.
Facility Managers
Sequences that match your operations
Your building's control sequences should reflect how you actually run the building — not the installer's defaults or the template from the last job.
Engineering Teams
Hand us the spec. We'll build it.
Give us a sequence of operations document. We'll implement it, commission it, and hand it back fully documented — no interpretation required.
Building Owners
Programming you actually own
Full documentation, no proprietary lock-in, and code you can hand to any qualified controls contractor. Your building's logic shouldn't be a black box.
