Why is it important?

i) The increase of roof ambient temperature can be offset by green roof. ii) The energy gained from building can be utilised to operate irrigation system for green roof during draught season. iii) Polluted rainwater runoff can be cleaned via green roof and improve the quality of collected rainwater in rain water harvest system. iv) Harvested rain water can be utilised to irrigate green roof during hot weather.
