In view of advancing global warming, climate change adaptation and mitigation measures for buildings are becoming increasingly important. The following article discusses the question of whether current urban planning principles still provide a suitable framework for this purpose. Therefore, the aim of this paper is to identify and quantify the main parameters of the urban planning framework regarding energy demand and energy generation of buildings. In a novel, holistic approach, passive design measures were evaluated in a joint analysis based on a case study in the city of Vienna (Austria) with respect to their impact on heating and cooling energy demand, overheating potential, daylight availability, and solar potential of new buildings. The results show that by improving the thermal insulation of the building envelope, the importance of a high compactness of the buildings to lower the heating energy demand is decreased. In addition, moderate compactness can help reduce the energy demand for space cooling and artificial lighting and increase the solar potential of the buildings. Accordingly, the results question the dogma of a high degree of compactness that still exists to some extent and indicate that changing climatic conditions also require new approaches in the urban planning process.

鉴于全球变暖的推进，建筑物的气候变化适应和缓解措施变得越来越重要。下面的文章讨论了当前的城市规划原则是否仍然为此目的提供了合适的框架的问题。因此，本文的目的是确定和量化城市规划框架中有关建筑能源需求和能源生产的主要参数。在一种新颖的整体方法中，基于维也纳市（奥地利）的案例研究，在联合分析中评估了被动设计措施对加热和冷却能源需求、过热潜力、日光可用性和太阳能潜力的影响的新建筑。结果表明，通过提高建筑围护结构的保温性能，建筑物高度紧凑对于降低热能需求的重要性降低了。此外，适度的紧凑性有助于减少空间冷却和人工照明的能源需求，并增加建筑物的太阳能潜力。因此，结果质疑在某种程度上仍然存在的高度紧凑的教条，并表明不断变化的气候条件也需要在城市规划过程中采用新的方法。
