As the use of Green Roofs increases, so does the need to improve the understanding of factors affecting their performance. To address this, the Institute of Biology, Environmental and Rural Sciences (IBERS) at Aberystwyth University in the UK embarked on a study which required a system for automated gathering and management of measurement data from Green Roof infrastructure.
A number of Green Roof modules with various combinations of substrate and plants were tested in an outdoor setting to asses not only agronomic perfromance but also their hyrological and thermal properties.
Using 36 bespoke and off-the-shelf sensors distributed across various types of green-roof growth module, Cultinova developed a customised measurement system which senses and transmits moisture, temperature, humidity and light-level data to the Cultinova web-service where it is stored and accessed on-line.
The resulting measurements database, consisting of 300,000 data-points captured over a 12-month period provided researchers at IBERS with a unique insight into Green Roof characteristics, enabling them understand key parameters affecting green roof operation and allowing improvements in Green Roof performance to be made.
