Building Automation & Controls

Specification: Niagara N4 & BACnet Open Architecture

Open-protocol Niagara N4, BACnet IP/MSTP, and non-proprietary DDC controls for central plants.

Engineering Scope & Overview

Western Mechanical Inc. deploys open-protocol Building Automation Systems (BAS) that eliminate vendor lock-in. We integrate multi-vendor chillers, boilers, air handlers, and pumping loops using Tridium Niagara N4 Framework, BACnet/IP, BACnet MS/TP, and Modbus RTU. Facility engineers gain 100% database ownership, customized graphics dashboards, and Title 24 Fault Detection and Diagnostics (FDD).

WMI Field Protocol & Certified Best Practices

• Non-proprietary architecture with open licensing (no locked JACEs or vendor contracts)
• Automated Title 24 Fault Detection and Diagnostics (FDD) compliance
• Dynamic chilled water and static pressure reset algorithms lowering utility peaks
• Secure encrypted web-based HTML5 graphical user interfaces with alarm notification

Frequently Asked Questions

What is the primary advantage of an open-protocol BAS over proprietary systems?

Open-protocol BAS built on Niagara N4 and BACnet ensures that facility owners own their software licenses, database backups, and station code. Any qualified contractor can service or expand the system, eliminating expensive single-vendor lock-in.

Can Western Mechanical integrate legacy chillers and older controls into Niagara N4?

Yes. We seamlessly bridge older BACnet MS/TP, Modbus RTU, and legacy proprietary communication trunks into modern web-based Niagara supervisor dashboards without requiring complete field equipment replacement.

How does BAS optimization satisfy California Title 24 energy mandates?

California Title 24 Section 120.2 mandates automated Fault Detection and Diagnostics (FDD), economizer damper monitoring, and dynamic temperature/pressure reset schedules — all natively automated by our open BAS configurations.
