????如今,全球城市人口首次超過農(nóng)村人口。在這個(gè)等式中,常常被忽略的是這種趨勢的加速度。以中國為例,它目前有6.5億人居住在城市,占到人口總數(shù)的52%。大約10年后,這個(gè)數(shù)字預(yù)計(jì)將高達(dá)10億。這意味著將有大約3.5億人(相當(dāng)于美國的全部人口)從中國農(nóng)村地區(qū)遷移到城市地區(qū)。百萬級以上人口的中國城市將達(dá)到221座。 ????人口的遷移帶來了挑戰(zhàn)。中國城市居民的平均能源消耗量是農(nóng)村居民的3倍。它意味著我們必須開發(fā)新城、重建舊城,以可持續(xù)的方式解決10億人的吃飯、居住、出行和工作的問題。今年的成都財(cái)富全球論壇“城市發(fā)展的重新思考”分論壇上,能源設(shè)備制造商和房地產(chǎn)開發(fā)商遠(yuǎn)大集團(tuán)(Broad Group)CEO張躍說,我們必須徹底重新定義究竟什么是城市生活。 ????“人們不想每天都得坐車、開車去上班,”他說。他的解決方法是,他打算修建摩天大樓來解決城市人口密集問題。他計(jì)劃在湖南省修建的預(yù)制裝配式高層建筑“天空之城”將達(dá)到202層,高度為838米。 ????張躍說,天空之城可在7個(gè)月內(nèi)完工,而其他超高層建筑至少需要5年,并且天空之城的能效提高了5倍。相比中國雜亂無章的普通開發(fā)項(xiàng)目,這幢建筑將節(jié)約200公頃左右的土地,包含了辦公場所、學(xué)校、娛樂場地、商店和餐館,從而降低對汽車的依賴性。張躍說:“天空之城將使道路上減少大約2,000輛汽車,因?yàn)樽粼谒麄兙幼〉牡胤骄湍苷业剿麄冃枰拇蠖鄶?shù)東西。” ????智能城市的另一個(gè)支持者是施耐德電氣(Schneider Electric)CEO趙國華。這家法國公司提供電力、電網(wǎng)、交通系統(tǒng)等方面的解決方案。趙國華說,城市可以利用社交媒體來使它們更具可持續(xù)性。他說:“巴黎人在一生中總共需要花費(fèi)一年的時(shí)間來尋找停車位?!彼f,他的公司正在開發(fā)讓司機(jī)可以利用社交媒體來尋找空置車位或避開交通擁堵的系統(tǒng)。 ????半數(shù)業(yè)務(wù)都與能效有關(guān)的工業(yè)巨頭霍尼韋爾(Honeywell)的CEO高德威舉了個(gè)生動(dòng)的例子來說明未來的城市怎樣大幅降低能源需求。這家公司設(shè)計(jì)的建筑管理系統(tǒng)整合了HVAC、照明和安全等核心系統(tǒng),在最大限度提高能效的同時(shí)實(shí)現(xiàn)成本節(jié)約。 ????全世界已經(jīng)認(rèn)識到了使城市更具可持續(xù)性的挑戰(zhàn),而且也擁有實(shí)現(xiàn)這一點(diǎn)的技術(shù)。但高德威說這還不夠?!拔覀儾荒茏屵@個(gè)過程變得混亂不堪。我們需要更充分的規(guī)劃。我們必須集思廣益,找到實(shí)現(xiàn)這一切的方法。” ????作為本次討論會的專家發(fā)言人,這三位企業(yè)高管無疑非常適合引領(lǐng)這樣的討論。(財(cái)富中文網(wǎng)) ????譯者:千牛絮 |
????Today, for the first time, more people worldwide live in cities than in the countryside. What's often missed in this equation is how fast this trend will accelerate. Take China. Currently 650 million people, or 52% of the population, now live in cities. Fast-forward only ten years or so and that number is expected to hit one billion. That means that some 350 million people, the equivalent of the entire population of the U.S., will move from the Chinese countryside into urban areas. The number of Chinese cities with a million or more people will hit 221. ????This migration presents a challenge. China's urban dwellers on average consume three times more energy than rural ones. That means we must design new cities and rebuild old ones in ways that will allow billions to live, drive, eat, and work sustainably. At today's session on Rethinking Our Cities at Fortune's Global Forum in Chengdu, Zhang Yue, the CEO of Broad Group, a maker of energy equipment and a real estate development company, said that we have to totally redefine what it means to live in cities. ????"People don't want to have to get on trains or drive a car to get to work," he said. One solution: Zhang plans to lick the urban congestion problem by building up. His proposed high-rise prefab in Hunan Province called Sky City will soar 202 stories to a height of 838 meters. ????Zhang says that Sky City can be built in seven months compared to at least five years for other super high-rises and is five times more energy efficient. The building will save some 200 hectares compared to typical sprawl development in China and will contain offices, schools, playing fields, stores and restaurants, reducing dependency on the automobile. Says Zhang: "Sky City will take some 2,000 cars off the road simply because its residents can find most of what they need right where they live." ????Another proponent of smart cities is Jean-Pascal Tricoire, the CEO of Schneider Electric, the French company that offers solutions for power, grids, traffic systems and more. Tricoire says cities can embrace social media to make them run more sustainably. "Parisians," he says, "spend a year of their lives looking for parking spaces." He says his company is working on systems where drivers can tap into social media and find an empty parking spot or avoid traffic jams. ????David Cote, the CEO of Honeywell (HON), the industrial giant that has more than 50% of its portfolio linked to energy efficiency, gave a telling example of how the city of the future will require dramatically less energy. The company has designed building management systems that integrate core systems such as HVAC, lighting, and security that maximize energy usage while providing cost savings. ????So the world has recognized the challenge of making our cities more sustainable and has the technology to do it. Cote says that's not enough. "We can't let this process be chaotic. We need much more planning. We need to get a lot of smart people in a room to figure out how to make all this work." ????The three executives on this panel would certainly be well-suited to lead the discussion. |
