Climate change sees IOC aim to choose 2030 and 2034 Olympics hosts at same time_我的网站

A |     Citing concerns about the effects of climate change, the International Olympic Committee said Friday it wants to pick two Winter Olympic host cities in July — putting Salt Lake City quickly into play for the 2034 edition.IOC president Thomas Bach said the Olympic body aims to confirm hosts for both the 2030 and 2034 Winter Games at its meeting on the eve of next year's Paris Olympics.Sweden, Switzerland and France have been working on possible bids for the 2030 edition and Salt Lake City officials have long targeted 2034. That would avoid the United States hosting back-to-back Olympics after the 2028 Los Angeles Summer Games.Picking Salt Lake City a decade in advance would give the IOC a trusted partner amid changing weather patterns and also could keep together people who have worked toward bringing the Olympics back the city that hosted the 2002 Games.The double award proposal by the IOC executive board still needs approval by the full membership at the Olympic body's annual meeting, which opens Sunday in Mumbai, India. That should be a formality.The IOC has declining options for Winter Games hosts. Bach noted that only 15 countries on three continents currently meet the criteria of having at least 80% of existing venues for snow sports and a “climate-reliable” outlook to host events in future decades.“We need to address very quickly this dramatic impact of climate change on winter sport,” Bach said in Mumbai. “By 2040, there remain practically just 10 NOCs who could host these snow events.”A likely longer-term project for the IOC is deciding on a rotation policy of a small pool of regular Winter Games hosts.The next deadline for the 2030 and 2034 Olympics will come Nov. 28-Dec. 1 at a board meeting in Paris. A single preferred candidate for each is expected to be chosen and then would enter into exclusive negotiations with the IOC.That is the new process for selecting Olympic host cities and regions, avoiding the once-traditional campaigns and votes which were at risk of vote-buying schemes.The Japanese city of Sapporo, which hosted the 1972 Winter Games, was once favored for the 2030 edition. That bid was officially dropped this week in fallout from criminal investigations and convictions for corruption tied to the Tokyo Olympics in 2021.___AP coverage of the Paris Olympics: https://apnews.com/hub/2024-paris-olympic-games。    在涿鹿经济开发区，有一家公司造的房子“会呼吸”。“为啥说这房子‘会呼吸’呢？因为它是被动式超低能耗建筑，即使不开窗通风，室内空气也能与室外循环，温度、湿度会自动调节，就像有了自然顺畅的呼吸。”8月14日，在中规低碳（张家口）建筑技术有限公司的样板房内，该公司市场部部长李宏利向客商介绍超低能耗建筑的优势。

8月14日，在中规低碳（张家口）建筑技术有限公司的样板房外，工作人员向客商介绍被动式超低能耗建筑的优势。日报记者 郭晓通摄窗外是交通主干道，样板房门窗紧闭，记者在室内听不到车辆驶过的声音，也感觉不到憋闷。从外表看，样板房与一般建筑差别不大，特别之处在于不依赖空调和暖气，室内温度可常年稳定在20至26摄氏度。“被动式超低能耗建筑就像保温瓶，夏天隔热、冬天保温，比传统建筑节能90%以上。

B | ”该公司副总经理杨冬明介绍，“会呼吸”的房子应用了10余项专利，采用了许多节能环保“黑科技”。

C | 在公司展厅，李宏利向记者展示了绿色建筑材料的神奇之处。她拿着便携喷火枪，烧灼一块薄薄的白色板材，板材竟无变化、不燃烧。

D | 记者用手触摸其背面，也感觉不到发烫。“这是用来制作墙体的轻骨料，防火、保温。”李宏利说，超低能耗建筑还搭配了高性能门窗系统，有效解决房屋夏天不隔热、冬天不隔冷的问题。针对超低能耗建筑气密性高的特点，该公司研发了新风系统，室外空气进入多功能一体机过滤，净化后的新鲜空气被输送到每个房间中。

E | 北方地区冬季寒冷，新风系统排出室内空气的同时，能将78%的热量进行回收利用，使房子达到恒温状态，避免了频繁开窗换气、冷风灌入的困扰。时间久了，超低能耗建筑内的空气会不会变差？在密闭样板房内，李宏利拿着手中的空气负氧离子检测仪给出了答案，检测仪上显示负氧离子数为2700个/cm3。“除了新风系统，我们还应用新型室内装修材料，常年缓慢释放负氧离子，使室内空气保持清新。

F | ”李宏利说。

G | 据介绍，装配式建筑作业像搭积木一样，采用系统化设计、模块化拆分、工厂制造、现场装配的方式建造，缩短建筑工期，节约建筑成本。

H | 如今，节能建筑在全国加速推广，促进城乡建设加快绿色转型。“这带来了更多的市场机会，目前我们已在京津冀及山西、内蒙古等地打开市场，让更多节能环保的好房子走进人们的生活。”杨冬明表示。（日报记者 郭晓通）。
