Urban Digital Twins:
A Tool for Urban-Scale Microclimate-Informed Building Energy Analysis

Project summary

This urban digital twin integrates building-level energy modelling, urban morphology, measured electricity-use intensity, and WRF-derived microclimate fields to support urban-scale analysis of building energy performance under different climate conditions.

Question

What characterises the heterogeneous building archetypes and urban forms in Singapore?

How

Building footprints are classified, linked to morphology and measured EUI, and aggregated to 500 m districts for cross-scale exploration.

Question

Do distinct microclimates exist across Singapore, and how do they vary during representative hot, cold, and transitional weeks?

How

Weather Research and Forecasting (WRF) representative-week outputs are converted to hourly 500 m fields for temperature, wind, humidity, and solar radiation.

How does microclimate influence building energy use across different seasons and districts in Singapore?

How

Weekly simulations compare non-microclimate and WRF-informed cases at building and 500 m district scales.
