When Delta established the first green building in the Tainan Science Park in 2006, the Company proactively pledged that all new plants and offices in the future will implement the concept of green building. In 2024, Delta’s new headquarters building and R&D center in India, located in the Bommasandra Industrial Area in Bengaluru, received LEED Gold certification. As of December 2024, Delta has built and donated 35 green buildings and 2 green data centers around the world.
Delta continues to expand products and energy-efficient solutions in green buildings and has received certification from the US Green Building Council (LEED), the UK Building Research Establishment (BREEAM), the Ecology, Energy-Saving, Waste Reduction, and Health (EEWH) system in Taiwan, and the Green Building Evaluation Standards in Mainland China. With the inauguration of green buildings, Delta has incorporated diverse greening into plant areas, ecological ponds, and other environmentally-friendly designs with positive benefits for biodiversity. Delta has also joined the United Nations Climate Change Conference, sponsored green building design competitions, and offered training courses related to green buildings to promote the application and foster talents in the field.
Delta has voluntarily set high standards for the Company by establishing comparison standards based on the EUI (kWh/m2/year) of local buildings. We calculate energy savings with reference to the ISAE 3000 assurance process, and in 2024 Delta's 21 certified plants and 5 donated green buildings saved 45,430 thousand kWh of electricity. These buildings together reduced carbon emissions by 23,330 metric tons CO2e.
In addition, Delta evaluates annual electricity savings using the PUE of data centers as the baseline. In 2024, Delta's certified green plants and buildings collectively saved, in total, 57,860 kWh of electricity and reduced carbon emissions by approximately 28.58 metric tons CO2e.
