R-Zero

IoT-enabled UV-C disinfection platform

Overview

R-Zero provides an IoT-enabled disinfection platform for indoor spaces that uses UV-C to kill pathogens on surfaces and in the air. It combines intelligent sensors, data analytics, and the Arc mobile UV-C tower to rapidly disinfect areas, with wireless sensors measuring occupancy to enable real-time risk intelligence and space optimization. The system is cost-effective compared with traditional chemical disinfection and HVAC solutions and is environmentally friendly, emitting low greenhouse gases and producing no chemical waste. Its goal is to create healthier indoor spaces by reducing pathogen exposure, optimizing space use, and lowering operating costs.

R-Zero deploys AI-driven HVAC platform at Stanford children's hospital, cuts energy use by up to 40%

R-Zero has deployed its AI-driven energy optimization platform at Lucile Packard Children's Hospital Stanford. The San Francisco-based company's system uses real-time occupancy data to automatically adjust heating, cooling, and ventilation in existing buildings, reducing HVAC energy use by 20-40% without retrofits or upfront cost. The platform integrates directly with existing building management systems and autonomously adjusts HVAC setpoints based on actual usage, rather than fixed schedules. R-Zero operates primarily through a shared-savings model with no upfront cost, targeting large portfolios including healthcare facilities, higher education, and corporate campuses. The company has raised $170 million to date from investors including La Caisse, Mayo Clinic Ventures, World Innovation Lab, John Doerr, and DBL Partners.

R-Zero's physical AI cuts building HVAC energy 20-40% with zero capital investment

R-Zero, a Physical AI platform for buildings, is reducing HVAC energy consumption by 20 to 40 per cent without capital investment or retrofits. The San Francisco-based company uses real-time occupancy data to optimise ventilation in existing buildings, addressing systematic over-conditioning as average commercial building occupancy sits at roughly 50 per cent whilst HVAC accounts for 40 per cent of energy use. At a 521,000-square-foot children's hospital, R-Zero achieved a 30 per cent reduction in HVAC energy use, saving 23,000 kWh whilst maintaining 100 per cent occupant comfort satisfaction. The platform integrates with existing building management systems and operates on a shared-savings model with no upfront costs. R-Zero has raised $170 million to date from investors including La Caisse, Mayo Clinic Ventures and DBL Partners.

R-Zero launches Room Intelligence to cut energy costs with real-time space optimization

R-Zero has launched Room Intelligence within its Connect platform, expanding its Physical AI system for buildings. The new capability translates real-time room-level utilisation into operational intelligence to reduce energy consumption, optimise ventilation and improve building performance. Room Intelligence unifies multiple data inputs into a single, room-level view aligned with how facilities teams manage buildings. Organisations can now understand how individual rooms are used over time, compare utilisation against capacity, and identify opportunities to rebalance room types or consolidate footprint. The system feeds real-time usage patterns into operational systems, enabling teams to make more precise decisions across ventilation, energy management and space planning. Room Intelligence is now available to all existing and new R-Zero customers.

R-Zero's Prospector AI identifies $3.8B in annual energy savings across 32,000 US buildings

R-Zero, a smart building platform, has expanded its Prospector AI software to the top 20 US metropolitan areas, analysing over 32,000 buildings with a combined annual savings potential of $3.8 billion. Originally launched in New York in December 2025, Prospector AI evaluates energy performance to identify cost savings, energy reductions and penalty avoidance for commercial building owners. The software uses publicly available building data and proprietary AI modelling to generate energy savings projections and compliance insights. The expansion addresses growing pressure from rising energy costs and stricter building performance standards. The top five markets—Washington DC, New York, Denver, Chicago and Boston—account for over $2 billion in potential savings. The platform helps property owners meet emissions reduction requirements whilst avoiding penalties that can reach $268 per tonne of excess emissions.
