Three Q1-Q2 2026 vendor moves (Butlr-Disruptive, Ricoh follow-on, VergeSense LSM) collapsed the single-sensor era. CRE GMs now choose fusion topology, not vendor. A 90-day decision tree across five stacks with capex bands, accuracy floors, and APAC privacy overlay.
VergeSense's Feb 2026 native Juniper Mist WiFi integration signals sensor fusion has crossed from bolt-on to default. Butlr 2026 benchmarks show no single sensor clears 95% — fusion does. APAC Juniper Mist users get a no-CapEx accuracy lift. Here's the 90-day pilot playbook.
Three vendor moves in early 2026 — VergeSense × Juniper Mist WiFi fusion, MultiTech × Niagara LoRaWAN driver, and UL-recognized A2L refrigerant leak detection — collapse a decade of sensor-fusion research into one specifiable RFP stack. 90-day action plan with APAC compliance windows.
92% of real estate companies run AI pilots, but only 5% hit their goals. The gap is fragmented sensor data, not the AI. This report covers the multi-sensor fusion architecture, vendor stack, and 90-day playbook for 20-30% HVAC savings.
Multi-sensor fusion delivers 23–52% HVAC energy reductions. This practitioner guide covers the minimum viable sensor kit, 90-day implementation path, and how OpenBlue, Building X, and Honeywell Forge handle fusion natively.
Microsoft's Beijing campus combined HVAC, CO₂, Wi-Fi, and PIR sensor fusion to verify 27.9% energy reduction under IPMVP Option A. The benchmark that redefined occupancy-based HVAC control at scale.
