Over 230 000 kWh saved annually at Korphoppet 1

Measurable savings across heating and cooling, year-round

Korphoppet 1 is a mixed-use commercial property in Hammarby Sjöstad, owned and managed by Fabege, one of Sweden’s largest publicly listed real estate companies. Originally built in 1949 and later transformed from industrial use, the 14,148 m² building spans eight floors. It is certified BREEAM In Use (Good) and connected to Stockholm’s district heating and cooling networks.

Myrspoven’s AI platform, myCoreAI, was deployed to optimize both distric heating and distric cooling systems simultaneously. Over a twelve-month period, the platform delivered pver 230, 000 kWh in verified energy savings, with AI control active more than 92% of the time across both systems, year-round.

A converted industrial asset in one of Stockholm's most dynamic districts

Located in Hammarby Sjöstad, one of Stockholm’s most active urban development areas, Korphoppet 1 sits at Hammarby Fabriksväg 43, close to waterfront promenades, public transport links, and a dense mix of businesses, restaurants, and services.

The property hosts a diverse range of tenants across its eight floors, with loading facilities accessible from both Hammarby Fabriksväg and Virkesvägen. All district heating and cooling delivered to the building comes from renewable sources, making energy efficiency a direct contribution to the property’s overall sustainability performance.

No hardware replacements. No disruption to tenants.

Myrspoven integrated with Korphoppet 1’s existing building systems without requiring any hardware replacements or major installation work. The platform connects to the building’s BMS infrastructure, continuously reads operational data, and begins optimizing energy intake within weeks of go-live.

Throughout the optimization period, the system has maintained stable indoor climate conditions. Energy use is adjusted in small, continuous increments, pre-heating or pre-cooling the building structure when conditions are favourable, and reducing intake during peak periods, without disrupting daily operations.

“The collaboration between us at Fabege and Myrspoven is driven by a shared ambition to make a real difference. By combining our expertise as a property owner with Myrspoven's data-driven analysis, we generate insights that translate into concrete actions in day-to-day operations. Together, we optimize energy use, reduce unnecessary consumption, and take steps toward buildings that are not only efficient, but also sustainable in the long term.”

– Linus Ask, Head of Operations and Technology, Fabege

Over 156,000 kWh saved on district heating over 12 months

Following activation of myCoreAI’s heating optimization, the building’s district heating system was continuously adjusted based on outdoor temperature, occupancy patterns, and thermal inertia. The AI maintained a potential savings rate of 160,000 kWh, with actual savings of 156,000 kWh, reflecting 92.2% average uptime.

All figures are based on verified platform data. Measurement period: 26 Feb 2025 – 26 Feb 2026.

In total, 156,806 kWh of district heating energy was saved over the 12-month measurement period, equivalent to the annual heating demand of approximately 8 to 10 Swedish apartments.

Over 74,000 kWh saved on district cooling across all seasons

In parallel with heating optimization, myCoreAI also optimized district cooling consumption at Korphoppet 1, a less common deployment that demonstrates the platform’s versatility across energy systems. Cooling savings were recorded consistently across all twelve months.

All figures are based on verified platform data. Measurement period: 26 Feb 2025 – 26 Feb 2026.

The 91.9% average AI uptime on the cooling system reflects consistent, uninterrupted operation, with forfeited savings of only 4,000 kWh over the full year.

Verified results across two energy systems, year-round

Korphoppet 1 demonstrates that AI-driven energy optimization can deliver substantial, measurable savings across both heating and cooling systems simultaneously, without hardware investment, without tenant disruption, and without compromising BREEAM certification targets.

With over 230,000 kWh saved over twelve months and AI control running at over 92% uptime, Korphoppet 1 stands as a strong reference for what is achievable in actively managed commercial real estate in Sweden.
