|Identifying the optimal development path of the conversion zones bears its own challenges. Given its location in the city center and surrounding developed areas, it is obvious why this project is paramount. It is yet to be determined whether it is possible to meet passive house standards while at the same time providing affordable living space. Another option could be to achieve CO2 neutrality through a greater use of renewable energies.||确定转型区的最佳发展路径要经得起自身的挑战。它位于市中心和周边发达地区，这解释了为什么这个项目是至关重要的。尚未确定的是，同时满足被动房屋标准并提供价格适宜的生活空间是否可能。另一种选择可能是通过更多地使用可再生能源来实现二氧化碳中和。|
|Additional solutions still must be found to achieve both economic and environmental sustainability for the development. The UN’s sustainability goals, which the city has committed itself to uphold, encompass all areas of city life. Living space, work, culture, and family as well as social aspects - like generational justice and equal participation are all a part of the development agenda.
Moving city development forward, it is important to find solutions ensuring no aspect of development is forgotten. These solutions in turn must be implemented as lighthouse projects creating new impulses for further development. In light of this reality, the International Building Exhibition “Wissen schafft Stadt” (knowledge creates cities) was created in 2012.
One key goal of the IBA is to pose important questions for the future. Now at midpoint of its initiation, and once perceived as an unrealistic luxury project, IBA has proven to be an important platform for governance, politics, science, and civil society. All developments are now tested whether they meet sustainability goals and integrate seamlessly into efforts previously taken by the city.
|然而，为了实现经济和环境的可持续性发展，其他的解决方案也是必要的。联合国的可持续发展目标包括城市生活的所有领域。生活空间、工作、文化、家庭以及社会范畴 - 如代际公平与平等参与权 - 都是发展议程的一部分。
推动城市发展，重要的是找到解决方案，确保不遗漏任何发展方面。这些解决方案也必须依次作为灯塔项目，为进一步的发展创造新的动力。鉴于这一现实，海德堡于2012年创建了国际建筑展“Wissen schafft Stadt”（知识创造城市）。
|Indicator based sustainability report for implementation of city development (STEP 2015) shows success in meeting sustainability goals, while pressing for action in key areas such as resource consumption, use of space, species diversity, and social integration.
IBA has shown how well sustainability is received by Heidelberg residents. The need to remove individual transportation from public areas, prioritize bike paths, and expand public transportation are all now public consensus. Sustainable and cautious future city planning requires consideration of broader context and long-term impact of projects.
The ability to free architecture from pure functionality, heterogeneously develop living space, avoid submitting to norms, and incorporate collective creativity engenders new process qualities and leads to a higher rate of acceptance by all parties involved. All this creates a matrix allowing us to let spectacular ideas turn into reality. Numerous single projects were developed with intensive public exchange. PH-Vision, a 21st century smart city district on a conversion site at the city’s edge, showcases how strategic approaches can influence existing districts and their sustainability potential.
