Digital Efficiency for Mixed Portfolios: aedifion and Green Fusion Form Strategic Partnership

Reducing operating costs, minimizing CO₂ emissions, and complying with regulatory requirements are key challenges facing the real estate industry. Buildings are among the largest global contributors to CO₂ emissions. In Europe alone, they account for approximately 40 % of final energy consumption and 36 % of energy-related CO₂ emissions. In addition, high energy costs, increasing CO₂ taxes, and a persistent shortage of skilled workers in technical operations continue to place additional strain on the sector. To meet climate targets by 2050 and avoid a loss in property value, intelligent, AI-powered technologies are needed across both residential and commercial portfolios to drive decarbonization and improve efficiency.

Optimized Operations From Apartment Blocks to Office Buildings

aedifion and Green Fusion have identified building automation and artificial intelligence as powerful levers to meet these challenges. Together, the two companies have developed a holistic offering to better support owners and operators in digitally optimizing their portfolios:

• aedifion contributes its AI-based software solution for optimizing complex technical systems in commercial buildings
• Green Fusion contributes its cloud-based energy management system for heating operations in residential buildings

aedifion: The Software Solution for Efficient Commercial Building Operations

At the core of aedifion’s solution is an AI-powered cloud platform that analyzes real-time operational data from building systems – such as heating, ventilation, and air conditioning – detects malfunctions and inefficiencies, provides actionable recommendations, and can autonomously control operations when needed. On average, this optimization enables energy consumption, operating costs, and CO₂ emissions in commercial buildings to be reduced by 22 %. Notable clients include BNP Paribas REIM, AEW, Strabag PFS, and MOMENI.

Additionally, aedifion offers a solution for intelligent electricity cost optimization. HVAC systems, photovoltaics, heat pumps, and energy storage units are intelligently coordinated and connected to the electricity market. Based on market prices and self-generated energy, the smart energy manager autonomously decides when to draw or store electricity – an essential component of the electricity-based heat transition in commercial real estate.

Green Fusion: The Energy-Saving Pilot for Residential Heating Systems

Green Fusion specializes in residential buildings. Its cloud-based energy management system uses artificial intelligence to monitor, optimize, and control heating and energy systems. A “Green Box” installed in the boiler room connects the heating system to the software. Implementation is handled by Green Fusion’s own technicians and trusted partner companies across Germany.

The result: significant energy savings without structural alterations – regardless of whether the building uses district heating, gas boilers, or renewable energy systems. Operating costs and CO₂ emissions are reduced, and the building’s energy efficiency class improves measurably. Over 100 companies in the housing sector, including Spar- und Bauverein Dortmund and Gewobag in Berlin, already rely on Green Fusion.

A Holistic Offering for Mixed Real Estate Portfolios

The strategic partnership between Green Fusion and aedifion creates a cohesive, scalable solution for digitally optimizing the operations of diverse building types – from residential complexes and office buildings to hotels, shopping centers, healthcare facilities, and logistics hubs. Thanks to open interfaces (e.g., standardized protocols or cloud-to-cloud integrations), both solutions work seamlessly together. Typically, the savings achieved exceed the licensing costs of both solutions – making the business case compelling and the benefits evident:

• ‍Holistic portfolio optimization: one integrated solution for both residential and commercial buildings – technologically intertwined, highly scalable, and interoperable‍
• Fast implementation without structural modifications: both solutions operate in a minimally invasive way using the existing building infrastructure – no extensive renovations required‍
• Measurable results: reduced energy consumption, CO₂ emissions, and operating costs based on real-time data and advanced AI – demonstrable and verifiable‍
• Regulatory compliance: Both solutions are TÜV-certified according to § 71a of the German Building Energy Act (GEG). For commercial buildings, they ensure the legally required continuous monitoring, logging, and analysis of all mainenergy sources. For residential buildings, they eliminate the need for separate heating system inspections under § 60b GEG

Two Solutions – One Shared Path

Through our strategic partnership, we demonstrate how digital building intelligence can deliver both ecological and economic benefits. Together with Green Fusion, we offer a comprehensive response to market demands – across all asset classes.
