Smart Joules DeJoule AI BMS and Cooling-as-a-Service

Smart Joules was founded in 2014 and is headquartered in New Delhi. It targets cooling and heating, the largest energy drain in hospitals, hotels, factories and offices, and aims to turn that waste into savings for clients while keeping comfort and reliability under service-level agreements.

Its core technology is DeJoule, an AI-powered building management system built for central cooling plants. It combines IoT sensors with edge reinforcement-learning software: CPO continuously optimises chiller plant operations and AHO optimises low-side air conditioning. Supporting tools include JouleOps for operations and maintenance, the Lumen AI chatbot for building questions, JouleTick for service requests on WhatsApp and JouleGenie for HVAC design. The company also delivers JouleCool (cooling as a service for new plants) and JoulePays (zero-capex retrofits paid from savings) for hospitals, hotels, campuses and industrial plants.

• DeJoule BMS: full-stack AI and IoT building management system designed for central cooling plants.
• CPO: edge reinforcement-learning software that continuously optimises chiller plant operations.
• AHO: edge software that automates and optimises air handling and low-side air conditioning.
• JouleOps: app and web tool for operations and maintenance management.
• Lumen and JouleTick: AI chatbots that answer building questions and handle service requests on WhatsApp.
• JouleCool and JoulePays: zero-capex models to build or retrofit cooling plants with guaranteed performance.

Private hospital groups in Vietnam can optimise chiller plants and air handling units to cut electricity bills without capital spending. Hotels and resorts can lower HVAC energy while keeping guest comfort. Food, pharmaceutical and textile factories with central cooling can use the shared-savings retrofit model.

The company reports Rs 302 crore of value created for clients and 37 crore kWh of electricity conserved. Case studies show DeJoule cutting chiller plant energy at ITC Panchla by 28% and HVAC energy at Aster MIMS by 15%, while JouleCool gave KIMS Manavata Hospital 30% energy savings with zero capex. Clients can buy the technology outright or pay from guaranteed savings.

Hospitals, hotels and factories in hot climates run large central cooling plants that are often poorly controlled. Rising tariffs and decarbonisation targets, together with development lenders financing efficiency in Asia, support zero-capex cooling and AI-based plant optimisation, a model Smart Joules has started to take to Southeast Asia with its first installation in Indonesia.

Founded in 2014 and headquartered in New Delhi. Raised a USD 5M Series A led by ADB Ventures in 2021, USD 8M debt from Denmark's IFU in 2024 and USD 10M from strategic investors in 2025. First international DeJoule deployment in Indonesia in 2024; in 2026 it was granted a patent for DeJoule Edge AI, expanded to New York and the UAE and was a finalist at Energy Tech Summit Asia in Malaysia.
