As global environmental problem has become a significant issue, we have already installed various energy saving method into our building services.
Especially, green roof and roof spraying have been watched keen interest, because they can reduce both heat load and carbon-dioxide emission from building services without using energy supply such as electricity.
Generally speaking, as building with green roof has water spraying equipment for tree maintenance, if we control water rate appropriately, we can expect a large heat load reduction effect which is brought by synergy effect of green roof and roof spraying.
