Build4People WP#5 “Urban Climate” Science Workshop at Royal University of Phnom Penh

On 10 October 2022, the Build4People WP#5 “Urban Climate” Science Workshop at Royal University of Phnom Penh (RUPP) took place.

On this occasion Prof Dr Lutz Katzschner presented the first draft of the Urban Climate Map of Phnom Penh developed with dedicated support from Dr Nyda Chhinh, Bunleng Se and Dr Daniel Choi from RUPP.

In course of his presentation Prof Dr Lutz Katzschner explained that urban climatic analysis with the outcome of an urban climatic map is an essential tool for sustainable urban development, particularly to reduce the urban heat island effects. Therefore, a comprehensive study of the meteorological conditions in Phnom Phan was carried out by the Build4People Work Package “Urban Climate” with strong support from research colleagues at RUPP, Royal University of Phnom Penh.

The introduction of the first Phnom Penh Urban Climate Map is a major milestone of the Build4People project because it provides a complete picture of a city wide structure of the urban heat island, hot spots but also areas which are needed for ventilation and nocturnal cooling. Moreover, is shows the important air corridors. The ventilation in Phnom Penh is characterised by dominating winds using these corridors but at the same time thermal induced circulations occur which are for advantage of thermal comfort and wellbeing.

The calibration of the map is carried out with reference station of all meteorological parameters set-up by the local research partners from RUPP. 

The method used is a standardised analysis carried out in many countries. The classification of climatopes in extreme heat to moderate and cool climates gives valuable recommendation for each neighbourhood and will be transformed to a urban climate recommendation map.
