75F IoT Building Automation and Saffron AI

75F is a building automation company with offices in the United States and the Asia Pacific region. It targets the large share of commercial buildings that lack smart controls, where a significant part of HVAC energy is wasted, and offers a wireless, cloud-based building management system that is cheaper and faster to install than conventional BMS projects.

The platform is vertically integrated: wireless sensors, smart nodes, thermostats such as the HyperStat, VAV controllers and a central control unit feed data to the cloud, where algorithms analyse each building every 60 seconds and make micro-adjustments to HVAC equipment. Software modules include Facilisight, Portfolio Analytics, Chiller Plant Manager, the Hayloft data-tagging tool and Saffron AI, a conversational assistant that answers questions, builds charts and changes schedules using the building's digital twin. Customers include offices, tech parks, hotels, hospitals and retail chains.

• Wireless sensors and controllers: Smart Node, HyperStat with eight on-board IAQ sensors, Smart VAV and a central control unit retrofit existing HVAC.
• Cloud optimisation: algorithms analyse building data every 60 seconds and make around 150,000 control decisions per site each day.
• Saffron AI: a conversational assistant that explains alarms, builds charts and changes temperatures or schedules in natural language.
• Chiller Plant Manager: dynamic chilled water balancing and plant optimisation for central cooling systems.
• Facilisight and Portfolio Analytics: web and mobile dashboards, heatmaps and reports across one or many buildings.
• Hayloft and APIs: Project Haystack data tagging and external APIs for integration with other systems.

Office buildings and tech parks in Ho Chi Minh City and Hanoi can retrofit existing chillers and air handling units without a full BMS replacement. Hotel and retail chains can manage HVAC and air quality across many sites from one dashboard. Hospitals can rebalance airflow and monitor IAQ in wards and diagnostic centres.

The company states that its predictive control can cut HVAC energy costs by up to 50%, with a return on investment in 1.5 to 2 years and payback under three years for customers in Asia. Its installed base has saved 93.9 GWh and avoided 74,180 tonnes of CO2. Case studies report 16% energy savings at Hiranandani Hospital and a 10% reduction at a Hilton hotel. Wireless retrofit avoids major rewiring of existing HVAC equipment.

Cooling dominates electricity use in commercial buildings across tropical Asia, and most mid-sized buildings still run without a modern BMS. Owners face rising tariffs, green building certification requirements and tenant expectations on indoor air quality, which favours low-cost wireless retrofits and AI tools that let small facility teams run buildings efficiently.

Founded and led by CEO Deepinder Singh, with offices in the United States and Asia Pacific. Investors listed include Breakthrough Energy Ventures, Accurant Investments and Revolution. The company earned SOC 2 compliance and was named to the 2021 Global Cleantech 100. In July 2026 Carrier Global acquired 75F; the brand continues within Carrier's Software & Controls Solutions business.
