Case study of technological innovations: integrated rooftop greenhouse
Location: Cerdanyola del Vallès, Spain
Typology: Rooftop greenhouse
Urban area: Inner city – Rooftop
Innovation type: Technological innovation
Main functions: Experimental research – Education and training – Resource-efficient food production
Users: Researchers – Companies – Students
In 2014, the research-oriented i-RTG was constructed on the top of the building that hosts the Institute of Environmental Science and Technology (ICTA) and Catalan Institute of Palaeontology (ICP). The purpose of the RTG-Lab is to demonstrate the feasibility of RTGs in Mediterranean areas and the potentialities of i-RTGs. The i-RTG will utilise residual heat from the building (e.g. lab air), CO2 concentrations in this residual air (i.e. which will be used as natural fertiliser) and rainwater collected from the rooftop.
Crops: Tomato, Lettuce, Green Beans
Techniques: Integrated rooftop greenhouse
Irrigation: Automatic fertirrigation – Rainwater
Use of renewable resources: Use of rainwater – Use of CO2-rich air
Sustainable practices: Production km.0 – Resource efficient design
