A/B Lersøgaard
As a cooperative housing association, Lersøgaard cannot take energy optimization or indoor climate lightly. That's why they've partnered with us at Kiona to strengthen their sustainable operations and identify problem areas in their buildings, located in the vibrant heart of Copenhagen.
Our journey with Lersøgaard began in 2017 as part of a collaborative project with Hofor, Copenhagen's central heating company. The primary focus was on load control – managing the buildings' energy consumption, especially in areas that suffered from poor cooling on their central heating systems. While the original project achieved its goals, the savings achieved with Edge, our energy optimization system, convinced Lersøgaard to continue using the solution after the project ended.
During this period, Edge proved its capabilities by significantly improving the cooling, and showed itself as a tangible tool for the managing staff to identify problem areas and inefficiencies.
Digitalization and rollout
The collaboration involved integrating Edge in Lersøgaard's buildings, consisting of two separate heating systems with a total area of 24,120 square meters spread over 335 apartments.
The installation included connecting the buildings to our cloud service, sensors on pipes to measure flow and return temperatures in the heating center and wireless room sensors in selected apartments. These components were integrated with existing meters and controls to form a single system.
In older buildings, nothing is ever perfect. With Edge, it's easier to identify what's working and where we can improve. It's especially important for us to operate as sustainably "smart" as we can and do our part for the environment, and Edge is an important tool in that job.
Today, the fixed measuring points in the buildings provide data to Kiona every 15 minutes, control the heating system and indoor climate, and monitor new measuring points for domestic hot water and water circulation. This ensures that all aspects of the building's energy usage are monitored and that our AI optimizes the heating in real-time.
Energy savings and reduced carbon footprint
For 2023, energy savings were estimated using degree-day corrected consumption data, with 2017 serving as the reference year. The results were impressive:
- Energy Savings: 13%
- Energy Savings in kWh: 362.000 kWh
- Financial Savings: approximately 27.120 EUR
- Reduced CO₂ Emissions: approximately 56.276 kg
The evolution of emitted emissions is calculated based on the current weighted energy consumption compared to the levels in the reference year. The reduction in CO₂ emissions is shown for the last 12 months.
Future outlook
Looking ahead, the partnership continues. The longer the buildings remain integrated with Edge, the greater the cumulative savings in energy and cost will be. Continuous monitoring and optimization will drive further improvements in energy efficiency and reductions in the carbon footprint.
Moreover, the data collected and analyzed by Edge will provide valuable insights for future projects, enabling Lersøgaard to make informed decisions about their energy management strategies.
The trust and close relationship established between our energy team and Lersøgaard's property managers emphasizes the importance of common goals and collaboration to achieve value and sustainability in responsible building management and building operations.
