Green
Roof
A green roof
design is adopted in the site office to enhance thermal insulation. It is
found that the temperature inside the ceiling void of the CED office nearby
has a high temperature up to 52oC at 2:00 under sunshine on a day with 33oC,
while for the green site office, the temperature of the ceiling void is
around 33oC under sunshine at 3:00p.m. Thus, it can be concluded that the
green roof have made significant effect to the thermal loading of the site
office building. Moreover, when using green roof, their shallow soil reduce
rainwater run off to less than 50% of normal, reducing the pressure on the
ground level drainage system. The rainwater retained in the soil supports
the plants, reduces the temperature, and through evaporation, it can humidifies
the air and reduces the dust levels.
