要做到这一点很难，对不对？但是对于参加太阳能十项全能竞赛（Solar Decathlon）的房屋，做到这一点并不难：这些房屋使停止碳排放行之有效，同时费用并不高……且其时尚的式样令人叹为观止。

太阳能十项全能竞赛于2002年由美国能源部（U.S. Department of Energy）发起，目前参赛国已包括中国、欧洲、拉丁美洲和加勒比地区国家。这项竞赛现在每两年举行一次，世界各地的高等院校纷纷设计、建造并展示利用太阳能发电的零排放房屋。这些采用现代技术的房屋代表了可持续生活的未来。

中国

上海同济大学已不止一次参加在欧洲和美国举行的太阳能十项全能竞赛。该校2010年赴欧洲的参赛作品是” “竹屋” 。这栋房屋产生的能量是其消耗的三倍多。 2011年，这个团队创造了” “Y-集装箱房” ，利用回收的集装箱制造经济实惠的太阳能房屋。

奥地利

奥地利维也纳技术大学（Vienna University of Technology）的参赛作品” “利时房” 获得上一届在美国举行的太阳能十项全能竞赛冠军。这所房屋可收集雨水用于浇灌庭院中的植物。其外墙幕可以移动并形成一个私密的“茧”状空间，多余的太阳能可为电动车充电。

美国

斯坦福大学（Stanford University） 2013年的参赛作品兼顾技术手段和经济适用性，围绕一个具有成本效益的预制 “核心”区域建造而成，“核心”区域有团队设计的电器和实现高效率的软件。Start.Home项目经理德里克·欧阳（Derek Ouyang）说，“这种核心如同住家内的发动机，可以在它周围建造任何外壳。”

2015年太阳能十项全能竞赛预定10月8日至18日在美国加利福尼亚州欧文市（Irvine, California）举行，美国、欧洲和中美洲的高等院校将组成代表队参赛。

据设计人员说，外形时髦的晶圆实验屋在2010年欧洲比赛期间被参观者称为“鲸腹”、“花生房”或“肉桂潜水艇”。最先进的柔性太阳能电池板赋予了其独特的造型。

拉丁美洲和加勒比地区国家：为参加太阳能十项全能竞赛建造新住房

今年，太阳能十项全能竞赛扩大到拉丁美洲和加勒比地区。在哥伦比亚卡利，莎莎舞者在利用人的行动发电的“动感舞池”上翩翩起舞，揭开了比赛的序幕。今年的比赛将注重于适合热带地区的社会保障房设计。

在零排放日到来之际，你也可以对自己提出挑战，尽量减少使用化石燃料。太阳能十项全能竞赛的参赛房和舞池使我们感到可持续发展的未来是光明的。

Zero Emissions Day? It’s every day at these houses.

On September 21, people around the world seek to minimize or eliminate their use of fossil fuels on Zero Emissions Day.

Difficult, right? Not at these homes built for the Solar Decathlon: They make cutting out carbon emissions practical, affordable … and breathtakingly stylish.

Started at the U.S. Department of Energy in 2002, the Solar Decathlon has grown to include competitions in China, Europe, and Latin America and the Caribbean. Every two years, universities around the world design, build and show off solar-powered, zero-emission houses. Using today’s technology, these houses represent the future of sustainable living.

China

Shanghai’s Tongji University is no stranger to the Solar Decathlon, competing in Europe and the United States. Its 2010 Solar Decathlon Europe entry, “Bamboo House,” produces three times as much energy as it consumes. In 2011, the team created “Y-Container,” an affordable solar house built with recycled shipping containers.

Austria

Austria’s Vienna University of Technology won the previous U.S. Solar Decathlon with “LISI (Living Inspired by Sustainable Innovation),” which collects rainwater to keep patio plants healthy. Exterior curtains can move to form a private “cocoon,” and excess solar energy can charge electric vehicles.

United States

Stanford University focused on technology and affordability in 2013, building a home around a cost-effective, prefabricated “Core” of appliances and efficiency software designed by the team. “The Core is like an engine for homes, and you can build any shell you want around it,” says Derek Ouyang, project manager for Start.Home.

The 2015 U.S. Solar Decathlon, which features teams from U.S., European and Central American universities, will take place in Irvine, California, from October 8 to 18.

Spain

According to designers, the funky “FabLab House” became known as “whale belly,” “peanut house” or “cinnamon submarine” to visitors at the Solar Decathlon Europe in 2010. State-of-the-art flexible solar panels enabled its unique shape.

Latin America and Caribbean: A new home for the Solar Decathlon

This year, the Solar Decathlon is expanding to Latin America and the Caribbean. To kick off coverage in Cali, Colombia, salsa dancers showed off a “kinetic dance floor” that generates electricity from movement. This year’s competition will focus on social housing designed for the tropics.

So today, challenge yourself to minimize fossil fuel use on Zero Emissions Day. Thanks to the houses (and dance floors) of the Solar Decathlons, celebrating the future of sustainability looks bright.
