The project
Two sites demonstrate the next generation of the managed blue-green roof: a research site at the Technion, building on the research foundations that accompany SmartFlow from its earliest days, and the Muslala rooftop in Jerusalem - an active green community roof in the heart of the city. On both, the roof combines vegetation, rainwater detention and irrigation - and SmartFlow runs all of it as one system.
The challenge
A blue-green roof only works when its two halves are coordinated: the vegetation needs water in summer, and the drainage needs free volume in winter. Without active management, the reservoir either sits full when a storm arrives or sits empty when the plants are thirsty. The site needed a system that adapts itself to the forecast - and also talks to the irrigation system.
The solution
SmartFlow manages the blue-green roof as a single system: the smart valve detains rainwater according to the forecast, the platform controls the irrigation computer and irrigates the vegetation with the detained rainwater, and Pelleg's shallow reservoir (our strategic partner) is managed from the same dashboard: filling toward summer, emptying ahead of a storm - automatically, on real-time weather forecasting.
What it proves
The Technion-Muslala pairing shows the managed blue-green roof working both in a research environment and on an active community roof in the middle of a city: same unit, same platform, two completely different contexts. Rainwater turns from a liability into a resource - runoff management in winter, irrigation in summer, and full documentation of every event along the way.
- One system for runoff and irrigation - less infrastructure, less maintenance
- Detained rainwater reused for the roof vegetation
- Pelleg shallow reservoir managed on real-time forecast
- Proven in a research site (Technion) and a live urban roof (Muslala)
