Green Fusion
Green Fusion offers a cloud-based, AI-powered energy management system for optimizing heating and energy use in residential buildings.
About
Green Fusion GmbH accelerates the heating transition in the real estate industry by providing a cloud-based, AI-powered energy and heating management platform. The company's solution, implemented via its Energiespar-Pilot (Energy Savings Pilot), continuously monitors, analyzes, controls, and optimizes heating and energy systems across entire real estate portfolios. With a focus on the residential sector, Green Fusion’s platform supports the digital transformation of heating systems, maximizes efficiency, reduces costs and CO₂ emissions, and enables a seamless shift to renewable energy sources such as heat pumps and photovoltaic systems. Their technology is manufacturer-agnostic, suitable for all types of heating systems (gas, district heating, heat pumps, BHKW, hybrid systems), and allows for remote and automated operation and optimization. Green Fusion partners with housing associations, municipal utilities, contractors, and energy supply companies to provide intelligent, sustainable, and cost-effective heating and energy management.
