高科技、低能耗：这届冬奥会的设施有何特别？
在9日举行的一次线上新闻发布会上，国际奥委会介绍了北京冬奥组委为这场将于2022年2月4日开幕的全球体育盛会所开展的准备工作，概述了有关场馆、防疫和仍在进行的测试赛等方面的具体信息。
国际奥委会北京冬奥会协调委员会主席小萨马兰奇在会上赞扬了北京冬奥组委为实现该承诺所做出的努力，他表示，北京冬奥会正在兑现碳中和办赛承诺，许多场馆都采取绿色能源供电，冰场采取新型二氧化碳制冷剂技术，实现碳排放全部中和。
跟小编一起来探索一下本届冬奥会的场馆和奥运村设施的特别之处吧~
环境友好型冬奥村
在北京、延庆和张家口三个赛区，北京2022年冬奥会和残奥会的奥运村居住区将为各国运动员及随队官员提供总计53天的住宿、餐饮、医疗等保障服务。
位于国家奥体中心南侧的北京冬奥村总建筑面积约33万平方米，由20栋住宅组成，可提供2338个床位，冬残奥会期间约1040个床位。作为张家口赛区配套设施的张家口冬奥村一共有10个组团31栋建筑，1668个房间。
Various facilities of the villages for Beijing 2022 Winter Olympics and Paralympics are set to serve the athletes, coaches and officials for a total of 53 days at the three competition zones of Beijing, Yanqing and Zhangjiakou.
Located south of the National Olympic Sports Center, the Beijing Olympic and Paralympic Village consists of 20 buildings spread over a construction area of about 330,000 square meters. It can accommodate 2,338 participants for the Olympics and 1,040 participants for the Paralympics, also offering catering and medical services.
Moreover, the Olympic Village facility in Zhangjiakou zone has been classified as Level 3, the highest level by the national Evaluation Standard for Green Building. It has 10 courtyards and 31 buildings with 1,668 apartments and 2,737 beds.
延庆冬奥村的建筑主体使用了超低能耗工程技术，能够使建筑的室内环境保持在20至26摄氏度、相对湿度30%至60%的舒适环境。同时，冬奥村还采用了被动房外窗，传热系数更小，隔热性能更好，和一般的外窗相比，更加节能。
Meanwhile, the village facility in Yanqing competition zone has been undergoing various tests as well, and rightly so since a range of advanced technologies are being used in it.
Its main structure uses ultra-low power technology for a comfortable environment by maintaining the indoor temperature between 20 and 26 degrees Celsius and relative humidity between 30 and 60 percent. Besides, it also adopts passive house windows that have a lower heat transfer coefficient, perform better in thermal insulation, and consume less energy.

更值得一提的是，延庆冬奥村是一个名副其实的“环境友好型奥运村”。
在设计施工建设过程中，项目建设团队通过和专业的园林公司开展合作，最大程度地保护了周边自然环境，将313棵原生树木作为延庆冬奥村最主要的景观原地保留下来。同时，积极打造“海绵型山村”，通过建设下凹式绿地、渗透沟和雨水调蓄池等措施，对雨水和生活污水全部进行处理净化，实现了再利用。
Not only this village is high-tech, but also nature friendly. During its construction, the surrounding natural environment was preserved to the maximum extent. In addition, by building sunken greenbelts, infiltration ditches and rainwater storage ponds, this village facility can treat rainwater and sewage for recycling.
智能机器人助力疫情防控
在新冠疫情之下举办冬奥会，防疫工作尤为重要。
北京冬奥会迎来了一群特殊的防疫小助手。
At Wukesong Ice Sports Center, a robot is used for disinfection. By spraying atomized mist on the ground, it can sterilize an area of 36 square meters within just a minute.
视频里的雾化消毒机器人已经在五棵松体育中心工作多日了。
这种雾化消毒机器人身高1.4米，安装有可以躲避障碍的传感器，单次能装16升消毒水，通过头顶上的四向喷头喷洒药剂，一分钟消毒面积可达36平方米，单台机器人最多可覆盖1000平方米以上，续航时间4到5小时。
It's about 1.4 meters tall, and the sensor inside can help it navigate around obstacles. It can store up to 16 liters of disinfectant, and its battery can last for four to five hours.
For smaller areas, an ultraviolet robot is used for disinfection, which is said to be more effective.
将于本届冬奥会“上岗”的机器人在运动场馆和奥运村内随处可见，它们有的可以提供消毒液并提醒人们佩戴口罩，有的可以代替人工进行安防巡检，还有一些则需要负责穿梭赛场内外送餐送物。
有了机器人的加入，人与人之间的直接接触便会减少，病毒传播风险将被有效降低。
And another robot can undertake the work of three to four human volunteers. It can walk up to people who are not wearing masks and tell them to wear one and has a contactless hand disinfection device on its head.
Wukesong Ice Sports Center will host the ice-hockey competition next February. Organizers are also testing a closed-loop system that separates athletes and staff members from the media and spectators.
People inside the loop will sometimes need things like paper documents, personal gear and medical equipment. Robots will be utilized to get those things in without breaking the rules.
The "delivery robots" will be on standby in the buffer zone. In this area, staff members can put objects on the robots, which can carry up to 300 kilograms.
Besides the robots, smart lockers will supplement the delivery service. They function very much like the lockers in Chinese communities. The delivery person puts the package inside the locker. Then a code is sent to the receiver, who then picks it up from the other side.
The difference is that robots will deliver things immediately. So, anything urgent should go to delivery robots, while the locker can store things for longer.
But they have a shared objective: to minimize person-to-person contact as much as possible.
