BMS & Smart Building Tech Vendors

Vendor landscape for building management and smart-building tech: 10 platforms controlling HVAC, lighting, power and energy in flexible workspace.

BMS & Smart Building Tech

Category note: Full BMS is largely landlord/owner territory - coworking operators who lease space usually inherit a building's BMS rather than buying one. The operator-controllable layer is lighter and cheaper: AI-HVAC overlays (75F, BrainBox AI), after-hours HVAC billing (Genea, see CAT-01), smart thermostats, and zero-CapEx wireless retrofits. The big seven below (Honeywell through Carrier) matter mainly to operators who own/develop their buildings or run large multi-floor footprints.

Vendors

Vendor Origin Markets Served Segment Notes
Honeywell United States Global Enterprise Building platforms span Honeywell Forge (analytics/optimization), the Niagara framework, and Connected/Advance controls. Reference-grade for owner-operators; rarely procured directly by leasing operators.
Siemens Germany Global Enterprise Smart Infrastructure portfolio - Desigo CC (building management), Building X (cloud suite), and the Xcelerator marketplace.
Johnson Controls Ireland Global Enterprise OpenBlue digital platform + Metasys BMS. An April 2025 Forrester TEI study claims up to 155% ROI - though that figure is driven largely by real-estate/portfolio value, not pure energy savings (energy component ~10%).
Schneider Electric France Global Enterprise EcoStruxure Building suite (including EcoStruxure Building Operation); strong on energy management + electrification.
ABB Switzerland Global Enterprise ABB Ability building solutions + i-bus KNX; strength in electrification and automation.
Trane Ireland Global Enterprise HVAC + controls (Trane Technologies). Acquired BrainBox AI in Jan 2025, folding autonomous HVAC AI and generative-AI optimization into its smart-building portfolio.
Carrier United States Global Enterprise HVAC + controls; Automated Logic (ALC i-Vu) BMS and the Abound cloud platform.
75F United States (Minnesota); APAC (India) ops Global SMB-Mid IoT-based BMS built for the ~90% of buildings without smart tech: HyperStat AI thermostats, smart nodes/dampers, 8-sensor IAQ monitoring, "software-defined hardware." Explicitly markets to coworking/offices; faster and lower-cost to install than legacy BAS.
Verdigris United States (Sunnyvale, CA) Primarily US Mid AI energy platform using smart sensors on electrical panels for consumption analytics, efficiency, and predictive maintenance.
Spaceti Czech Republic Europe Mid Smart-building platform combining occupancy/IoT sensing, workplace experience, and building middleware (cross-listed in CAT-22).
