Green Fusion is a German startup, founded in 2021, that develops an AI-powered cloud-based energy management platform for the housing sector. The platform monitors, analyzes, and optimizes heating systems in real time across entire residential property portfolios, with the goal of reducing energy costs and CO2 emissions while preparing buildings for the transition to renewable energy.
The core product connects and orchestrates a range of building energy systems - including gas heating, district heating connections, heat pumps, photovoltaic panels, and battery storage - through sector coupling. Rather than treating each component in isolation, the platform automates and optimizes the full operation of a building's energy infrastructure. Green Fusion's approach is grounded in the observation that most heating systems in Germany run far below their potential, often locked into factory default settings that waste both energy and money.
The technical stack spans artificial intelligence, real-time control and optimization, building energy systems, and portfolio-level energy orchestration. Key domains include:
- AI-driven monitoring and optimization of HVAC and heating controls
- Integration of PV, battery storage, and district heating via sector coupling
- Digitalization and automation of boiler rooms and building operations
- Portfolio-wide energy management for housing companies
Green Fusion operates in Germany and targets housing companies and residential property managers as its primary customers. The company is at an early stage, having been founded in 2021, and takes a software-first approach to building energy operations.
