To Irrigate or Not to Irrigate?
While irrigation may only be needed during protracted hot dry weather (to sustain the plants), there are other reasons to install an efficient means of irrigating one’s green roof. Irrigation allows the green roof to be fully optimized. With the ability to irrigate during hot dry weather the rooftop can be turned into one big cooling unit and save money on air conditioning. Remember water liberates 8000 BTU of energy during evaporation (latent heat of evaporation), and pumping water is efficient and cheap, but running air conditioners is inefficient and expensive. The cooling effect derived by irrigating allows for the conservation of energy in comparison to the energy wasted on cooling by less efficient methods.
