On May 26, 2021, the 3rd China Solar Decathlon Roadshow Harbin Station was held in Harbin Institute of Technology, and Sayyas participated in the event as a specially invited enterprise.
Solar Decathlon (SD) is a solar-powered building technology competition initiated and hosted by the U.S. Department of Energy. China Solar Decathlon is one of the outcomes of the U.S.-China strategic and economic dialogue. The program is designed to improve the ability of university teams to design, build and operate solar buildings that are cost-effective, energy efficient and attractive.
In this competition, Harbin Institute of Technology teamed up with the University of California, Berkeley to form the HIT&UCB team that made it to the finals. They uses widely grown rice straw as the wall envelope to reduce the environmental impact while improving the building's energy efficiency based on the traditional straw bale building and combined with the actual situation in northeast and north China. They also developed a modular straw bale wall envelope by combining the idea of prefabricated and modular buildings.
During the roadshow, Mr. Sun Chunhai, chief engineer of Sayyas, shared the current severe energy consumption situation of buildings, the advantages of aluminum-clad wood windows in energy conservation of buildings, and the predestined relationship between Sayyas and this competition for the students and teachers who participated in this event:
Mr. Sun Chunhai, chief engineer of Sayyas
Hello everyone. Today I come to Harbin Institute of Technology to participate in the 2021SDC roadshow with you. I feel very honored!
On September 22, 2020, at the 75th Session of the United Nations General Assembly, President Xi Jinping promised the world that China would achieve emission peak by 2030 and achieve carbon neutrality by 2060. Building energy consumption, transportation energy consumption and manufacturing energy consumption are our three major energy consumption, and building energy consumption has exceeded 40% of the total energy consumption of our society. There are three stages of building towards the goal of zero energy consumption: ultra-low energy consumption building, near-zero energy consumption building and zero energy consumption building.
Today's SDC competition is promoting solar houses, which is one solution in the evolution of zero-energy building design. Sayyas has always been ahead of the national standard in the energy saving of building doors and windows. In 2010, we visited the Passive House Institute (PHI) in Germany under the guidance of Chairman Bian Shuping. We were the first Chinese enterprise to visit PHI! In 2012, the first Chinese passive aluminum-clad wood window developed by Sayyas obtained the certification of PHI in Germany, which was the first product in China to win this honor.
In 2013, The P120 product of Sayyas participated in the SDC competition. The teams from Xiamen University and Harbin Institute of Technology achieved the 6th and 9th place respectively. In 2018, the P120 product once again helped South China University of Technology and Xiamen University to win the championship and the second runner-up of SDC competition.
The concept of Sayyas is to produce the world's most energy-efficient door windows in the world's most energy-efficient passive factory, so that the world's buildings will be more energy-efficient because of Sayyas's door windows.
On behalf of all the employees of Sayyas, I would like to welcome you to our passive factory for a visit.
Finally, I wish the teachers and students of HIT a great success in the 2021 SDC competition.
As a window enterprise which always takes energy saving and emission reduction as its own duty, Sayyas always sticks to the first line of energy-saving building windows. Sayyas focuses on the research, development and manufacturing of energy-saving building windows, and takes "Extremely Reduced Consumption, Extremely Beautiful Life" as its corporate mission. Many years ago, Sayyas has independently developed a passive ultra-low energy green factory project, and this year, it carried out energy-saving renovation of the headquarters office building of Sayyas in Nanjing. Sayyas leads by example to practice the "Green Initiative" as a window enterprise!
Since President Xi Jinping put forward China's "3060" dual-carbon plan in September 2020, China has accelerated the pace of ultra-low energy consumption green building development to continuously expand the actual landing area and accelerate the realization of the vision of green and healthy life.
Sayyas also hopes to influence more young people to join in the action of energy conservation and environmental protection through its own actions.
Therefore, in addition to deeply participating in the China Solar Decathlon competition, Sayyas also launched the "Zero-carbon Youth" activity in 2021 to implement the zero-carbon idea from the perspective of youth and understand the zero-carbon building in China from the perspective of youth.
Sayyas will always actively practice its mission and make its own contribution to the fight against global warming.
