Harnessing AI for Cost-Effective Heating Management: A Case Study from Umeåhus 14

In a bid to alleviate rising heating costs without sacrificing comfort, the board of Brf Umeåhus 14 in Umeå decided to explore innovative solutions. With a property built in 1967, characterized by subpar insulation and high heating bills, the question was pressing: how to reduce expenses while maintaining a pleasant indoor climate? The answer came in the form of an AI-driven heating optimization service from Riksbyggen, which specializes in property management. Roland Lundberg, chairman of Umeåhus 14, revealed that their quick decision to adopt the AI service stemmed from a realization they might not have pursued independently. "We probably would have never thought of this ourselves if they hadn't raised the issue," Lundberg noted, emphasizing their previous struggles with energy consumption. However, the transition to algorithm-controlled heating wasn't without its challenges. Some residents voiced concerns over temperature drops, while others feared that the sensors signaled an invasion of privacy. To address these apprehensions, the board strategically installed sensors in half of the apartments, primarily those on the exterior, striking a balance between technological advancement and resident comfort. The setup was swift and uncomplicated, consisting of small sensors—a noticeable improvement over traditional systems. Within just a day, the installation was complete. The results speak for themselves: between March 2023 and March 2024, the heating consumption plummeted from approximately 707,000 to just over 533,000 kilowatt-hours—a remarkable 24 percent reduction. This led to savings of around 113,000 SEK, a substantial boon for the association. "It may not sound like much compared to larger associations, but for us, it means a lot," remarked Lundberg. With operating costs reaching about 18 million SEK, freeing up funds for maintenance and savings was crucial, especially amidst challenging interest rates. Beyond financial benefits, the improved heating management has significantly enhanced residents' daily experiences. Many have reported a more even and comfortable indoor climate. The AI system adjusts heating based on various conditions—including outdoor temperatures and solar radiation—ensuring optimum thermal comfort. "Some still feel it is cold, but we can show in the measurements that the temperature is correct," added Lundberg, highlighting a newfound assurance in temperature accuracy. The effectiveness of Riksbyggen's AI service was underscored by additional findings during a ventilation check, which revealed the building was overventilated. Addressing this alongside AI optimization contributed to remarkable improvements—what Riksbyggen project manager, Mattias Palmqvist, referred to as a "double effect." By leveraging modern technology, the service continuously learns and adapts to maintain energy efficiency without compromising on comfort. It utilizes data from indoor sensors and weather forecasts to fine-tune heating outputs—transforming the approach to indoor climate management. Lundberg expressed satisfaction in relaying positive outcomes to the board, a group traditionally inundated with complaints. "When you're on a board you only hear complaints almost all the time. Therefore, it's nice to be able to say we've saved on heating costs and achieved a more even climate. It's something positive to convey and it feels good." This initiative's success has broader implications, according to Palmqvist, who pointed out that having tangible data helps explain discrepancies in temperature perception among residents. It empowers the board to make informed decisions and adjustments based on actual measurements. For Lundberg, the results are clear: investing in this AI-driven technology has not only been financially prudent but has also fostered a more comfortable living environment for residents. "This costs a bit but in the long run you save money. The larger the association, the more it pays off, especially if you have buildings from the 60s or older with poor insulation," he concluded. To sum up, Brf Umeåhus 14 serves as an exemplary case of how technology can be harnessed effectively to tackle energy challenges, proving that with the right tools, significant savings and improved quality of life can be achieved.
