Bahnstadt - vision turn reality
火车城-前景变为现实
Bahnstadt is a vision turn reality for an entirely clean energy city district. Built entirely to passive house standards, households in this neighborhood need only a fraction of energy compared to those in the old city center. CO2 savings exceed 50%, and heating energy needs have been reduced by 75%. The remainder of electricity needed is produced in a climate-neutral wood-fired power plant. A heat reservoir is currently under construction, which will provide additional storage optimization and use of clean energy produced on site.
Bahnstadt is the largest passive house development in the world, and compensates for higher energy use levels in the city’s historic center. The city center’s potential for energy savings, while improvable, is limited.
Lessons learned through Bahnstadt development (with expected completion in 2022) are already implemented to further other urban development projects.
Energy-saving streetlamps, expansion of public transport, optimization of modal split, use of rain water, open-space concepts for water accummulation, district heating, car sharing, bike highways, and new ideas for kids playgrounds all originate from Bahnstadt, Heidelberg’s 100% climate neutral city district. Even municipal plans for energy production optimization such as communal heating stations, solar installations, hydroelectricity, and now the heat reservoir were conceived under the auspices of Bahnstadt.
After winning the passive house award for Bahnstadt, Heidelberg has committed itself to building all new developments to passive house standards city-wide. It is plain to see that one plan alone has led to the development of dozens of new projects and identified synergies throughout the city.

海德堡火车城把完全使用清洁能源的前景变成了现实。城区内的建筑完全按照被动节能标准建造。与老城中心区相比，此区域内的家庭只需要极少的能源。二氧化碳减排量超过50％，热能需求量减少了75％。所需的电力来自气候中和型的燃木发电厂。一个储热器正在建设中，它将被用来提供额外的能源储存优化，并使用本地生产的清洁能源。
火车城是世界上最大的被动节能屋开发项目，可以平衡城市历史中心区较高的能源使用水平。市中心的节能性虽然可以得到改善，但效果非常有限。
开发火车城的过程中所获取的经验（预计在2022年完成）已被应用在其他城市发展项目上。
节能路灯、公共交通覆盖面的扩大、交通方式选择优化、雨水再利用、用于积蓄雨水的开放式空间、区域供暖、共享汽车、自行车高速公路以及儿童游乐场的新想法都源自于火车城这一海德堡100%气候中和的城区。甚至市政计划中的能源生产优化，如公共加热站，太阳能装置，水电以及如今的储热器，都是在铁道新区的规划中构想出来的。在火车城赢得被动房屋奖后，海德堡承诺在全市范围内建造符合被动房屋标准的新项目。仅此一个计划就促成了数十个新项目的开发，创造了整个城市的协同效应。
