Current practice Reality
Building to be simulated
Urban Heat Island : Cities are warmer than its surrouding
Should UHI be considered while conducting building simulations ?
Measurement data can be fed to a global model
But resolution of a Global Model is of the order of a few hundred Km
Mesoscale grid Heat Island Effect”
Grid for global modelsMesoscale Model
(Resolution: few meters to Km)
Mass: Heat Island Effect”
The effects of building is included in the source terms Di
Input to the model: Boundary Conditions, Landuse and Topology data
Mesoscale Grid Heat Island Effect”
Urban GridUrban Parameterization
Height above sea level: Varies from 400m-2000m
City core is always hotter (Urban Heat Island)
Entrainment of cooler air towards the center
Base Temperature: 291 KRESULTS: Cooling Load
Linear relation between energy demand and cooling load.
