external pageHigh‐Resolution, Multilayer Modeling of Singapore's Urban Climate Incorporating Local Climate Zonescall_made

This paper describes the application of the Weather Research and Forecasting (WRF) model's Multilayer Urban Canopy Model (MLUCM) to simulate the urban climate of Singapore during a hot period in April 2016. The LCZ map for Singapore was developed by adopting the World Urban Database and Access Portal Tools (WUDAPT) methodology based on satellite remote sensing imageries and building height data.

external pageClustering weather types for urban outdoor thermal comfort evaluation in a tropical areacall_made

This paper applies a clustering method to yearly weather files with the aim of obtaining representative boundary conditions for urban microclimatic models. The results describe typical-day weather situations commonly known as weather types. The study is carried out in the hot and humid tropical conditions of Singapore.

external pageRecommendation system for climate informed urban design under model uncertaintycall_made

This paper shows a novel recommendation system for optimal urban design from a socio-economic and an Outdoor Thermal Comfort (OTC) perspectives. The framework is based on risk measures which quantify and take into account various important design criteria such as OTC, spatial use in the form of exposure maps and the investment cost of the design.

external pageWillingness to pay for urban heat island mitigation: a case study of Singaporecall_made

This paper shows Singaporeans’ willingness to pay (WTP) for UHI mitigation strategies by implementing a contingent valuation analysis. Specifically, a double-bounded dichotomous survey design on a representative sample of 1,822 online respondents was applied.

external pageInteraction between heat wave and urban heat island: A case study in a tropical coastal city, Singaporecall_made

This paper studies heat waves in Singapore in April 2016 using ground observations and the Weather Research and Forecasting (WRF) model. This study shows that the heat wave-UHI interaction in a tropical city can be different from that in cities in the temperate climate zone. More studies should be conducted in tropical cities, which are projected to suffer larger impacts of increasing heat stress.

external pageA decision support tool for climate-informed and socioeconomic urban designcall_made

This paper describes the development of a novel statistical decision-theoretic framework for urban design analysis from an outdoor thermal comfort (OTC), social and economic perspectives. These aspects are combined into spatio-temporal risk measures, which provide a compact representation of the overall quality of an urban design scenarios (UDS) set.  

external pageUrban heat island mitigation in Singapore: Evaluation using WRF/multilayer urban canopy model and local climate zonescall_made

This paper describes the application of the Weather Research and Forecasting (WRF) model to assess UHI mitigation scenarios for the tropical city of Singapore during April 2016, including two heat wave periods. The local climate zones for Singapore were used as the land use/land cover data to account for the intra-urban variability.
