Blue roofs can also be fitted with smart controls and electrically operated valves to regulate water discharging from the roof. The electrically operated valves can be tied to predictive weather algorithms to forecast incoming rain or snow events as well as extreme heat days. Based on the weather forecast, valves may be opened and closed to accommodate additional rain or snow loads. When coupled with a rainwater harvesting system, blue roofs increase rainwater storage capacity to meet non-potable water demand (ie. toilet flushing or irrigation) without the need to oversize tanks. Rainwater harvesting tanks with smart controls are able to coordinate with blue roofs to draw water from the roof when the tank water level is low to meet demand and offset municipal potable water use.
