"The construction of the project started on January 22 this year, and at present, the old training hall has completed the demolition of the ground and equipment, the structural reinforcement of the venue, and the structural layer and waterproof layer of the new ice rink. The new training hall and competition hall are being reinforced. Qin Xulin, director of the engineering department of Harbin Urban Development Investment Group Co., Ltd., the venue builder, introduced that after the project started construction, the project department reversed the construction period and formulated a general schedule in the way of preparing the construction network plan, and it is expected to complete the structural reinforcement project of the three venues in mid-May, and strive to have the conditions for the test match at the end of September to complete the construction and management handover.
How to integrate the concept of low-carbon environmental protection into the renovation process?"The environmentally friendly materials such as decorative coatings, plates, and adhesives used in the renovation process of the venue have been strictly screened. Qin Xulin told reporters that for the construction of the venue in the environmental quality of the building materials, in strict accordance with the executive committee materials "white list" directory selection, inspection of the material certificate, production license, test report and other supporting documents, on the basis of the provisions of the conventional testing items qualified, and then entrust professional institutions to carry out special environmental testing, the generated data analysis, simulation of on-site use scenarios for pre-assessment, qualified and then used. In addition, the whole process of sampling, sample selection and testing of building materials is tracked, image records are kept to ensure the transparency and traceability of the whole process, and the selected materials are displayed and sealed.
Qin Xulin introduced that all kinds of facilities and equipment used in the museum are new types of equipment on the market, such as air conditioning units, ice-making systems, dehumidification systems and other equipment are high-efficiency and energy-saving products. The use of these devices can greatly reduce energy consumption, increase power output, and achieve efficient operation. The transformation of the ice rink refrigerant is also particularly important, this transformation abandons the traditional ethylene glycol refrigerant, and will use R134A refrigerant, which not only has good refrigeration effect, but also saves energy and is environmentally friendly.
The renovation construction of the venue was started
During the visit, the reporter learned that the Harbin District 8 Sports Center 9th Asian Winter Games competition venues and supporting facilities upgrading and renovation project, involving the old training hall to rebuild a standard ice rink (26 meters × 60 meters), the competition hall to improve the function of ice-making process equipment, the replacement of convertible boundary walls, the transformation of the stadium sound reinforcement system, the transformation of the special lighting system, the weak current engineering security, communications, network system transformation, etc., the outdoor project involves the temporary finished room, the entrance gate of the venue, the temporary fence, the landscape engineering, Ground maintenance works for car parks, road works, winter ice sculpture works and maintenance of outdoor rain and drainage networks.
The venue was renovated to achieve renewable energy
As the venue for the opening and closing ceremonies of the 9th Asian Winter Games, the Harbin International Convention and Exhibition Sports Center is currently undergoing preparations before the renovation. The renovation will open up areas B and C of the Harbin International Convention and Exhibition Sports Center, adding 17,000 seats. In the renovation of the stadium project, Kazakhstan will pay special attention to the use of renewable energy and environmental protection technology.
"The design team will maximize the use of natural light and air flow, reducing reliance on artificial lighting and ventilation systems. Liu Danyang, the venue designer of the opening and closing ceremonies of the Architectural Design and Research Institute of Harbin Institute of Technology, said that with the goal of green and low-carbon environmental protection, the optical fiber sensing technology will accurately control the energy consumption of the venue, the intelligent curtain will reduce the carbon emissions of daytime lighting, and the energy-saving ceiling of low-radiation film materials will be fully utilized into the transformation of the entire venue, which can not only effectively reduce the level of carbon emissions, but also ensure the recycling of resources in the competition.
In addition, the steel structure of the grandstand in the hall will adopt prefabricated construction technology, through factory processing and on-site assembly, which not only reduces the welding fume pollution caused by on-site construction and welding, but also greatly shortens the construction period, which not only protects the environment, but also effectively uses resources.

"During the construction process, before acceptance, before the handover of the building and management, and before it is put into use, we will test the indoor environment in batches. Strictly control and remove the content of air pollutants, such as formaldehyde, benzene, ammonia and other harmful substances. Liu Danyang told reporters that they will also kill bacteria in the indoor environment. If a problem is found, a professional organization will be requested to purify it in time to ensure that the indoor environment meets the standards during the use of the opening and closing ceremonies.
New environmental protection technology makes the venue "breathe"
Green and low-carbon competition is the purpose of the 9th Asian Winter Games, Harbin vigorously promotes the supply of green energy, through the use of a large number of new environmental protection technologies, to create a "breathing" green and low-carbon venues.
"In the renovation of the venue, we adopted advanced low-carbon, energy-saving and environmental protection technologies such as urban sponge engineering and air source heat pumps to create a 'breathing' green building. Liu Qinghui, head of the environmental protection class of the Asian Winter Games Organizing Committee, told reporters that in terms of green buildings, Harbin pays attention to the energy-saving design of venue buildings to ensure that lighting, heating and air conditioning systems meet national standards.
During the interview, the reporter learned that in order to actively promote low-carbon construction, Harbin City implemented the existing building renovation strategy, through the use of old buildings for transformation, which not only saves resources, but also reduces the generation of construction waste.
"Harbin City carries out strict 'source control' of environmentally friendly materials. Establish a 'white list' system and select reputable suppliers with green certifications.
