Energy efficiency in buildings undeniably plays a vital role in addressing climate change. At the level of building planning, a thorough analysis with thermal dynamic calculations can be carried out to assess energy demand and resulting CO₂ emissions of buildings due to the high level of detail usually provided at this stage. In urban planning design on the other hand, energy and resource-related parameters are usually not quantified, as at this stage of the planning process other urban planning factors predominate the concepts. However, numerous aspects that are determined at the stage of urban planning cannot be changed anymore later on in the process even though, they can have a significant impact on the energy demand. This includes the structuring of the building blocks, density and height of the buildings, orientation and inclination of the surfaces as well as greening of the outer shell and availability of direct solar radiation. This paper describes the analysis of parameters, which have a significant influence on energy and resource consumption of urban developments. This includes new developments as well as the existing building stock in order to provide quantifiable indicators for refurbishment and densification measures. The simulation tool CityCalc, which has been developed in a previous research project provides the environment for the analysis. To validate the approach, the identified parameters are analysed in an exemplary case study for a Viennese urban development area. The results aim at identifying and quantifying the key influencing parameters of urban planning design on the energy and resource efficiency of new and existing urban development areas in order to gain essential insights for the integration of climate-relevant factors for future planning processes.

不可否认，建筑物的能源效率在应对气候变化方面发挥着至关重要的作用。在建筑规划层面，可以通过热动态计算进行全面分析，以评估能源需求和由此产生的 CO ₂由于通常在此阶段提供的高度详细信息，建筑物的排放量。另一方面，在城市规划设计中，能源和资源相关参数通常没有量化，因为在规划过程的这个阶段，其他城市规划因素占主导地位。然而，在城市规划阶段确定的许多方面在以后的过程中不能再改变，即使它们会对能源需求产生重大影响。这包括建筑块的结构、建筑物的密度和高度、表面的方向和倾斜度以及外壳的绿化和直接太阳辐射的可用性。本文描述了参数分析，这些参数对城市发展的能源和资源消耗有重大影响。这包括新的发展以及现有的建筑存量，以便为翻新和致密化措施提供可量化的指标。在先前的研究项目中开发的模拟工具 CityCalc 为分析提供了环境。为了验证该方法，在维也纳城市开发区的示例性案例研究中分析了确定的参数。研究结果旨在识别和量化城市规划设计对新的和现有城市开发区能源和资源效率的关键影响参数，以便为未来规划过程中气候相关因素的整合提供重要见解。
