Résumé

The energy efficiency improvement potential in industrial buildings is often significant, considering all unutilized waste heat flows. Cost efficient and innovative renovation concepts are needed for a good balance between cost savings and investment costs including energy grants for new energy systems. The paper presents a case study, motivated by financial savings and CO2 emission reductions for an industrial building in Finland based on realized costs and measured energy consumption. The building belongs to a company with multiple industrial facilities in Finland and around the world and the company fulfils its energy program Mission to Zero, significantly reducing the carbon footprint of its buildings. The energy renovation concept studied in this study relies on a novel heat pump-based energy recycling system utilizing boreholes for thermal storage and free cooling. Sources for energy recycling are the cooling and pressurized air systems serving the production line. The long-term renovation plan is included to improve the overall cost efficiency. The energy concept is compared to the initial situation and a conventional ground source heat pump system utilizing free cooling from the boreholes. The measurements indicate that the performance, (SCOP 3.3) and heating energy covered by the heat pump system (about 97%), has been better than expected based on the energy calculations.
