Abstract:
High-density residential developments on outskirts of cities with a large number of detached multistorey
houses on small blocks of land are actively promoted as a solution to urban migration in
many countries. Such a concentration of houses can have adverse effects on the micro-climate due
to the presence of a large number of roofs which have a tendency to warm the surrounding air,
leading to heat island effects. The use of insulated roof slabs provides an alternative that may
enable the creation of green cover at roof level. In this research, the performance of different
insulation thicknesses has been evaluated, indicating that a minimum thickness of 25 mm would
be desirable in tropical climatic conditions. The effect of creating green cover was determined with
actual models. It is proved with comparative studies that shading screens can be used to simulate
the presence of green cover with computer simulations. This is important in predicting the performance
of insulated roof slabs for buildings of different layouts.
