<h4>Irrigation</h4>

Regular irrigation has been shown to substantially reduce the stormwater capture benefit of an extensive green roof[http://ascelibrary.org/doi/abs/10.1061/(ASCE)HE.1943-5584.0001534]. However, due to their limited water retention capacity many green roofs are coupled with a cistern to capture the excess water. It then becomes desirable to use as much harvested water to regain the cistern capacity,  Green roofs can be irrigated to saturation daily throughout the growing season without damaging the vegetation.
