Green Buildings

Delta has built or made donations of 27 green buildings and two green data centers around the world. In 2019, its 15 office buildings and the five buildings that it sponsored, which were certified green buildings, saved a total of 21.48 million kWh of electricity--the equivalent to a reduction of 13,415 tons of carbon emissions.

As a green building advocate, Delta promises that future new plants or office buildings as well as buildings it sponsors, will be green buildings. Delta will continue to make good use of its core technology capabilities to develop smart energy-saving solutions and invest in the application and promotion of green buildings.​​​​​​​​​​​​

  • Corporate Green Buildings

    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 27 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 15 green office buildings and the five academic green buildings that it sponsored according to the ISAE3000 assurance process.

    In 2019, Delta's global certified green office buildings saved more than 19.73 million kWh of electricity and reduced carbon dioxide by around 12,485.6 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 2019, Delta's data centers certified as green buildings saved more than 257,766 kWh of electricity and reduced carbon dioxide by 193.5 metric tons of CO2e.
