HISTORY & CONTEXT

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.
