Since Delta established the first green building in the
Tainan Science Park in 2006, it has promised that all of its
new plants and offices in the future will implement the
green building concept. So far, Delta has built and made
donations of 33 green buildings and two green data centers
around the world.
Delta applies its products and energy-saving solutions to green buildings and has successively obtained certificates, including LEED from the U.S. Green Building Council (USGBC), BREEAM from the Building Research Establishment (BRE), EEWH, and the China Green Building Label. The annual electricity consumption of the floor area (EUI,
kWh/m2 set by local building standards is adopted as a comparison benchmark. Delta has calculated the energy it has saved through its 17 green office buildings and the five academic green buildings that it sponsored according to the ISAE3000 assurance process.
In 2022, Delta's global certified green office buildings saved more than 26.91 million kWh of electricity and reduced carbon dioxide by around 15,400 metric tons of CO2e. Delta evaluates the electricity-saving effect based on power usage effectiveness (PUE) of its data centers' server rooms every year. In 2022, Delta's data centers certified as green buildings saved more than 53,557 kWh of electricity and reduced carbon dioxide by 27.51 metric tons of CO2e.
