[ESCO Project Case Studies] Kawachi Yakuhin Co., Ltd. / Chofu City Hall

Can be implemented with zero initial investment costs! An energy-saving promotion measure that does not require any new burdens.

We will introduce case studies of ESCO projects that are fundamentally based on covering all costs (construction costs, interest, expenses of ESCO operators) with the savings from reduced utility costs achieved through energy-efficient renovations. At Kawachi Yakuhin, temperature sensors were installed in the store to implement intermittent operation to avoid excessive cooling and heating. Additionally, by adding an initial illumination correction function to the lighting, energy savings were achieved while maintaining a constant brightness in the store. After the introduction of the ESCO project, they successfully reduced annual energy consumption by 16.1%. At the Chofu City Hall, various energy-saving methods were implemented, including the renovation of gas absorption chillers to high-efficiency blind heat pump chillers and ice thermal storage. Compared to before the introduction of the ESCO project, annual energy consumption was reduced by 14.2%. 【Main Energy-Saving Methods (Kawachi Yakuhin)】 ■ Air conditioning intermittent operation control ■ High efficiency of lighting equipment ■ Introduction of refrigeration control (dehumidification heater control) ■ Introduction of inverter control devices for refrigeration units ■ High efficiency of air conditioning equipment (inverter air conditioning units) ■ Introduction of a monitoring system for verification *For more details, please refer to the PDF document or feel free to contact us.
