Chengdu Universiade | Recyclable, New Energy, High Technology - Chengdu Universiade showcases a green trend, green energy | Universiade

Chengdu, August 2 (Xinhua) - Whether it's low-carbon operation measures to strengthen resource reuse, new energy transportation vehicles shuttling through the streets and alleys, or sports venues that meet the two star standard of green buildings, the Chengdu Universiade embodies the concept of "green, smart, vibrant, and shared" in every aspect of its hosting.

"Recyclable and Reusable" can be seen everywhere

Every staff member dining at the Chengdu Universiade venue has become accustomed to separating food residues and lunch boxes, and displaying the green label of the Chengdu Universiade on the garbage bin for sorting and disposal.

"This lunch box is actually a biodegradable and recyclable material," said Fan Ye, a volunteer at the water polo venue, pointing to the lunch box in the journalist's hand. Not only that, but also marked areas have been set up on the drinking water bottles provided in the main media center and venues to avoid water waste.

Recyclability and reuse have permeated all aspects of the Chengdu Universiade.

"You can put the finished bottles in and exchange them for gifts." Chinese water polo team athlete Wang Beiyi noticed a special facility in the Dayun Village - people throw discarded mineral water bottles, cans, and other items into the interior. The machine immediately scans and analyzes the discarded items and generates a carbon score receipt, which can be used to exchange corresponding gifts.

"This facility is called the 'Low Carbon Rubik's Cube' and is located in both the Universiade Village and competition venues. We hope that this fun interaction can encourage people to practice a healthy and low-carbon life," said on-site staff member Fu Shijing.

Not only that, more than 300 "snowflake chairs" in the press conference hall of the Chengdu Universiade Main Media Center are all leased from the Beijing Winter Olympics Main Media Center, which not only saves costs but also maximizes the use of resources.

New energy vehicles are everywhere

Like the new energy vehicles that can be seen everywhere in the streets and alleys of Chengdu, the Chengdu Universiade also practices the concept of "green travel" in the use of vehicles.

In the Dayun Village, new energy shuttle buses have become a daily transportation tool that Spanish Taekwondo player Alexander Rodriguez must use. These shuttle buses stop at 10 stations, carrying athletes to and from their accommodation, restaurants, and other places every day.

"During the Universiade, a total of 1340 new energy buses and more than 1000 new energy small vehicles were used for transportation services. 90% of the transportation from the Universiade Village to the central urban area venues used new energy vehicles, while 100% of the internal transportation within the Universiade Village used new energy shuttle vehicles," said Du Shengge, Deputy Minister of the Urban Work Service Department of the Chengdu Universiade Executive Committee.

In addition, Chengdu fully utilizes the opportunity of the Universiade to stimulate industrial vitality, actively leverages local industrial advantages, accelerates the integration of new energy facilities such as charging and swapping, photovoltaics, and hydrogen energy. The Longquan competition area is equipped with 50 "Longquan made" hydrogen fuel vehicles for event support, and the PetroChina Ancient City Oil Hydrogen Joint Station in Pidu District has been completed and put into operation, alleviating the hydrogen demand for over 100 local buses.

Building facilities showcase "technological style"

Facing the scorching sun and high temperatures of nearly 40 degrees Celsius, the reporter walked into the life service center of Dayun Village, feeling refreshing and refreshing, but without any air conditioning.

Originally, this building adopted the traditional Chinese technique of "cold alleys" - in ancient times without air conditioning, craftsmen designed a unique architectural structure that could produce natural ventilation, thereby cooling the building.

"The physical principle of a 'cold alley' is that when the airflow passes through an area that becomes wider and narrower, it accelerates to form negative pressure, bringing more outdoor airflow and taking away more indoor hot air and moisture." Lu Yixiu, an architect at China Southwest Design and Research Institute of Architecture, said that this' cold alley 'building can save about 70000 kilowatt hours of electricity per year without air conditioning.

In addition, all 13 newly built venues at the Chengdu Universiade have reached the 2-star standard for green buildings. The Chengdu Xindu Xiangcheng Sports Center has built a rainwater recycling system, which can convert the retained rainwater into water for the greening and maintenance of the venue. It can save more than 3000 tons of water annually. The power generation glass in tennis competition venues is used to provide power for indicating road signs. In addition to using cadmium telluride power generation glass, some competition venues are also equipped with ground source heat pump systems to generate electricity for the venues.

"We will refer to the Beijing Winter Olympics and strive to release the 'Chengdu Universiade Green and Low Carbon Organizing Report' one month after the competition, extract typical cases, and form the Universiade Green and Low Carbon Practice Heritage." Du Shengge said that after preliminary calculations by third-party verification agencies, the Chengdu Universiade will reduce carbon emissions by about 26000 tons after fully implementing source reduction measures.
