VRV Air Conditioner Installation Project to Replace the Split-Type System

This project is part of the Company’s energy conservation initiatives implemented alongside the renovation of Building C. Previously, the building used split-type air conditioning systems, which consumed relatively high levels of electricity and required frequent maintenance. During the renovation of the 7th floor of Building C for office use, the Company installed a VRV (Variable Refrigerant Volume) air conditioning system, which is better suited to the operational layout and offers higher energy efficiency than the previous system.

Performance Results (July 1 – December 31, 2025)

• Based on actual energy consumption measurements within the operational area, the VRV air-conditioning system reduced electricity consumption by 25,934 kWh compared with the previous split-type system.
• The estimated full-year performance is expected to achieve electricity savings of approximately 51,867 kWh per year.
