Building Automation Resources for California Facility Teams
Welcome to the Signet Controls resource library. Our engineers write these posts & guides for the people who actually run California’s buildings — facility directors, energy managers, property managers, mechanical contractors, GCs, and ESCO partners.
You won’t find marketing fluff here. Instead, you’ll find practical technical content.
Every post & guide tackles a real challenge our clients face, and links to deeper resources when you want to dig further. Browse by topic below, or jump to the latest posts.

Open Protocols & Niagara Framework
→ The Brutal Truth About ‘Open’ Building Automation
Every BAS vendor calls their system ‘open.’ Most aren’t. Learn the three layers of openness and the questions that expose vendor lock-in.
→ Why Niagara Crushes Multi-Vendor Building Chaos
How the Niagara Framework unifies BACnet, Modbus, LonWorks, and proprietary stacks into one operator interface. Plus why TCP certification matters.
→ Niagara AX is Dying: Why You Must Migrate to N4 Now
Tridium’s AX platform is on a managed sunset. What the N4 migration requires — hardware, station conversion, modules, graphics, and the security overhaul.
BACnet & Network Architecture
→ BACnet/SC: The Critical Security Shift Owners Miss
Classic BACnet has no encryption. BACnet/SC fixes it with WebSockets and TLS. What owners and engineers must know about the transition.
→ BACnet Networks: 4 Costly Design Mistakes to Avoid
Flat networks, oversized MS/TP trunks, BBMD misconfigurations. The four mistakes that wreck BACnet performance — and how to design networks that last.
Cybersecurity & Federal Compliance
→ OT Cybersecurity: The Silent Threat to Your Building
Why building automation networks became attack targets — and the six core moves that protect them. NIST SP 800-82, BACnet/SC, and CMMC Level 1.
→ CMMC Level 1: The Federal Mandate You Can’t Ignore
The DoD’s CMMC rule took effect November 10, 2025. What Level 1 requires, why it matters for BAS contractors, and what facility teams must do now.
Sensors & Hardware
→ BAS Sensors: 7 Hidden Lies Wrecking Your Comfort
Bad sensors silently sabotage building performance. The seven sensor types every BAS depends on, where each one fails, and how to calibrate them.
→ Wired vs Wireless Sensors: The Critical Decision
Wireless sensors save labor. They also create maintenance and security headaches. When wireless wins, when wired wins, and how to choose smart.
Energy Performance & Commissioning
→ Demand Response: California’s Untapped Revenue Stream
OpenADR, IOU programs, CAISO ELRP and DRAM. How California buildings turn flexible loads into $5,000–$30,000+ per year in verified DR revenue.
→ FDD: Turn Wasted HVAC Data Into Real Savings
Most BAS systems collect tons of data and use almost none of it. How fault detection and diagnostics surfaces the faults wrecking your HVAC efficiency.
→ RCx, Recommissioning, OCx: Stop Confusing These Terms
Commissioning, retro-commissioning, recommissioning, ongoing commissioning. They’re not the same. Which one your building actually needs, and why.
California Code & Compliance
→ Title 24: Why Most Projects Fail Acceptance Testing
First-try acceptance test failures cost weeks and tens of thousands. The four most common failure modes — and the three habits that prevent them.
Vertical Deep Dives
→ Hospital BAS: 5 Brutal Lessons From the Field
Hospital BAS is unforgiving. ASHRAE 170, pressurization control, reliability engineering, and the failure modes we see across California’s hospitals.
→ Higher Ed Controls: Escaping the Campus Portfolio Trap
Universities can’t replace controls all at once. The Niagara-based supervisory architecture that lets campuses standardize incrementally over decades.
Go deeper with our cornerstone guides
Each cornerstone guide expands on a topic that runs across multiple blog posts. They’re where to start when you want the complete picture.
★ OT Cybersecurity for Building Automation
The complete framework. NIST SP 800-82, the six core moves, BACnet/SC, and CMMC Level 1 for federal facilities.
IPMVP framework, baseline development, persistence, and verified savings tied to incentives and demand response.
★ Title 24 Part 6 for Building Controls
Mechanical and lighting control requirements, acceptance testing, and what’s changing in the 2025 code cycle.
★ Demand Response & Grid-Interactive Buildings
OpenADR 2.0b and 3.0, California IOU programs, CAISO participation, and where DR is going next.
