EPD certificates – which quantitatively demonstrate environmental performance data including global warming potential resulting from construction, depletion of the ozone layer, creation of photochemical ozone, and potential for acidification or eutrophication – unfortunately are not in a digital format that can be read by computers. The TurCoMDat database has been developed to support the developments in green building certification systems, to address the need for quantitative calculation of environmental performance and design optimization in buildings, and to respond to the need for digital information for the purpose of integrating environmental performance data of construction materials into Building Information Modelling (BIM) systems. With these services, SÜRATAM supports the development of sustainable buildings in Turkey.
