The Holiday Inn Hotels & Resorts brand is renowned worldwide for its first-class service and welcoming atmosphere. The 4-star hotel in Düsseldorf‘s Quartier Central meets the needs of a wide range of travelers in one of the region‘s most sought-after locations. Spread over six floors with 209 rooms, a light-filled lobby, various conference rooms, and a restaurant, the hotel offers inviting interior design and a cozy ambiance, making it the perfect place to relax and unwind.

The owner‘s goal was to gain a deeper understanding of the technical operations at the Holiday Inn to identify potential savings more quickly and sustainably reduce operating costs. Additionally, the property was to be transitioned into automated, user-focused regular operation to ensure maximum efficiency and comfort at all times.
Based on the results of a detailed building analysis, aedifion developed a specific retrofit roadmap to prepare the hotel for digital operational optimization. Since then, the cloud platform has enabled transparent real-time monitoring of all technical systems and has automatically implemented optimization recommendations during ongoing operations.
13 400 € annual operation cost savings (1 €/m²/a)
137 MWh annual energy savings (10,25 kWh/m²/a)
23,5 t CO2 annual avoided emissions (1,75 kg /m²/a)
To meet the requirements for efficient building operations at the Holiday Inn, three phases were crucial:
When optimizing the hotel‘s operation, the focus was initially on the running times of the air handling units. By adjusting the time schedules in the conference and kitchen areas, it was possible to achieve demand-oriented operation instead of a 24-hour operation. In the restaurant, the air volume flows were adjusted so that this system no longer runs unnecessarily at full capacity. For the air handling systems in the kitchen and social areas, a dynamic control of running times and supply air temperature was implemented. The set points for the heating and cooling systems are also dynamically regulated to ensure they operate at optimal efficiency. By reducing the pump heads, the temperature spread was normalized and energy consumption reduced. The system temperature for hot water preparation was lowered from 80°C to 70°C without compromising water hygiene. By integrating additional meters and sensors from Deepki and Disruptive Technologies, it was possible to address “blind spots” in the database, allowing for the real-time capture and analysis of information that had not been considered before.
Through the implementation of the aedifion cloud platform, the Holiday Inn was operationally optimized and transitioned to a transparent, proactive operational management within just one year. By establishing comprehensive data sovereignty and continuously identifying potential savings, not only are the energy efficiency and user comfort of the hotel improved, but its returns and value are also sustainably enhanced.
“With aedifion‘s cloud platform, we have a powerful tool to better oversee and continuously improve the technical operations of our hotel. The team provided excellent guidance and support during the retrofitting of missing hardware and communication protocols. From prioritizing optimization measures to the implementation and ongoing performance monitoring, we are thoroughly satisfied!“
