Extreme weather conditions give green roofs a hard time: extreme temperatures and long periods of drought can have a devastating impact on the vegetation. This limits the variety of plants than can survive, and leads to high maintenance costs.
RainBrain tackles this problem by optimizing the water availability in and around green roofs. The system constantly monitors the vegetation health, watering needs and available water. For instance, RainBrain detects when plants have too little water, and can automatically water the green roof. On the other hand, if a heavy rainfall event is predicted that could lead to floods throughout the city, RainBrain empties water buffers proactively to create more storage capacity.
