The 2021 Delta Cup International Solar Building Design Competition kicked off on March 21 at Beijing “cloud” platform. The livestream of the competition drew more than 20 media participants along with 13,000 viewers watching online. It echoes Chinese 2060 carbon neutralization goal. To contribute wisdom for green building to solve the climate problems around the world, this competition theme, “Sunshine Low Carbon Community,” aims to recruit outstanding works throughout the world, in the hope of promoting low-carbon and building a green and healthy living environment. For the first time, the competition includes virtual and realistic categories. A construction site in Tibet for the public to observe and experience.

Bruce Cheng, the founder and honorary chairman of Delta indicated in his speech that, starting from itself, Delta has built and donated 27 green buildings plus two green data centers throughout the world, and the energy conservation performance has improved all the way from the earliest level of 30%. Some of their energy efficiency improved so much that they even achieve the goal of “Nearly (Net) Zero Energy Building.” This year happens to be the 50th anniversary of Delta. At this time, we anticipate that, while developing new products and solutions, our colleagues will also dedicate their efforts to climate mitigation.

The brand event themed on the “application of renewable energy in buildings”, began in 2006 and it has been held for nine consecutive years with 8,700 teams participating from all over the world. A total of 1,724 valid works, covering a variety of buildings, such as the construction of new rural communities, beautiful rural communities, urban housing, renovation of existing buildings, sunshine primary schools, architectural adaptation to old buildings, kindergartens, etc., were submitted. Delta has further supported implementation and construction of the winning works. To this day, five pieces (sets) of works have been completed.

Lei Zhang, the secretary general of the Solar Building Expert Committee of Chinese Renewable Energy Society hosted the opening ceremony of the competition
