Abstract It is explored, in this work; some well-known classic methods to calculate thermal comfort, contrasting them with a method proposed here that based on the Principal Components Analysis for Doha Metropolitan Region (DohaMR) Qatar. The takes into account natural outdoor space, which influenced by external atmosphere variables. purpose of comfort index measure atmospheric variability and ...

The worsening urban heat island (UHI) effect poses a great challenge to the thermal comfort of people outdoors. However, there has not been summary mechanisms by which UHI affects outdoor (OTC). This paper reviews commonly used OTC evaluation indexes, data collection methods, and mitigation measures discusses relationship between OTC. review is limited peer-reviewed journal publications found i...

Over the last two decades, urban geometry has been shown to be a key determinant of microclimatic conditions in areas. This study uses Ladybug-tools, plugins Grasshopper3D optimise building heights, street widths and orientation maximise outdoor thermal comfort, represented by diurnal average Universal Thermal Climate Index (UTCI). In hot-arid climate Cairo, Egypt, optimised parameters symmetri...
