Streets are the fundamental elements of urban form in terms of microclimate as well as place making in cities. Microclimate itself is influenced by climate critical parameters of the Local Climate Zone Classification (LCZ) system. Therefore, a key design question is the role, if any, of LCZ classification for climate guidelines at street scale.

In this paper we explore the Intra LCZ zone temperature variation at three street typologies with North- South and East-West orientation within the city core of Glasgow as a case study. We then investigate the compatibility of LCZ parameters related to openness (determined by sky view factor and aspect ratio) and surface properties (determined by albedo) with Glasgow City Council's Development Plans Policies and Proposals for street design in order to identify the possibility of using these parameters for climate sensitive street design.

The results suggest that a fixed design strategy would not be applicable across all street typologies and that the identified LCZ parameters combined with form-based parameters of orientation and façade geometry can play a vital role in climate-sensitive street design.

用于气候敏感型街道设计的局部气候区参数的兼容性:开放性和表面特性对局部气候的影响

就小气候以及城市中的场所营造而言,街道是城市形态的基本要素。小气候本身受本地气候区分类(LCZ)系统的气候关键参数影响。因此,关键的设计问题是LCZ分类(如果有)在街道规模的气候指南中的作用。

在本文中,我们以格拉斯哥市中心为中心,以北向南和东西向的三种街道类型探索了LCZ内区域温度变化。然后,我们研究与开放度(由天空视图因子和长宽比确定)和表面特性(由反照率确定)相关的LCZ参数与格拉斯哥市议会的街道设计发展计划政策和建议的兼容性,以确定使用这些可能性的可能性气候敏感街道设计的参数。

结果表明,固定的设计策略不适用于所有街道类型,并且已识别的LCZ参数以及基于形式的方向和立面几何形状参数可以在对气候敏感的街道设计中发挥至关重要的作用。
