Cities and urban agglomerations are particularly vulnerable to the expected impacts caused by climate change. A building-resolving urban climate model as a tool for urban planning can contribute to prepare to these issues. However, currently available urban climate models do not correspond to the level of expertise of the various stakeholders in planning practice and their respective computing infrastructures.

The German research program Urban Climate Under Change [UC]² aims at the development, validation and application of a high-resolution and user-friendly urban climate model (PALM-4U) for entire cities. UseUClim, one of four joint research projects, reviews PALM-'s user-friendliness and practicality by applying the living lab approach.

Living labs are platforms that gather all relevant stakeholders and, hereby, support a systematic user-science interaction. Both stakeholders from urban planning practice and model developers provide crucial input to the successful co-development of a scientifically-based and practicable urban climate model. Consequently, it is important that both contribute on an equal footing. To ensure this equality, UseUClim acts as a neutral intermediary between the two. Throughout the project it became apparent, that key success factors are clear and transparent communication flows as well as a common understanding of the project goals.

城市和城市群特别容易受到气候变化带来的预期影响。将建筑物解析的城市气候模型作为城市规划的工具，可以有助于应对这些问题。但是，当前可用的城市气候模型与规划过程及其各自的计算基础架构中的各个利益相关者的专业水平不符。

德国研究计划“城市气候变化” [UC] ²旨在为整个城市开发，验证和应用高分辨率且用户友好的城市气候模型（PALM-4U）。UseUClim是四个联合研究项目之一，它通过采用实时实验室方法来回顾PALM-的用户友好性和实用性。

生活实验室是一个平台，聚集了所有相关的利益相关者，从而支持系统的用户与科学互动。城市规划实践的利益相关者和模型开发者都为成功共同开发基于科学和可行的城市气候模型提供了重要的投入。因此，重要的是两者都应平等参与。为了确保这种平等，UseUClim充当了两者之间的中立中介。在整个项目中，显而易见的是，关键的成功因素是清晰，透明的沟通流程以及对项目目标的共识。
