The characteristics of the full-scale pilot of a modular tray-based blue roof (BR) system installed to control runoff from the roof terrace of a building of the Catania University campus (Italy) are described in this paper. The BR was installed in one quadrant of the terrace while another quadrant was left unmodified to allow comparison. The paper also describes preliminary results of the monitoring of the BR during the first storm event which was captured. The analysis of the results shows the installation to provide a flow peak reduction of about 55% for the analysed event.

Abstract

The characteristics of the full-scale pilot of a modular tray-based blue roof (BR) system installed to control runoff from the roof terrace of a building of the Catania University campus (Italy) are described in this paper. The BR was installed in one quadrant of the terrace while another quadrant was left unmodified to allow comparison. The paper also describes preliminary results of the monitoring of the BR during the first storm event which was captured. The analysis of the results shows the installation to provide a flow peak reduction of about 55% for the analysed event. The monitoring of the system on the long term will allow evaluating the system detention and retention performance, as well as the definition of standards for BR design in urban areas.
