The Integrated Carbon Metrics project quantifies the carbon emissions for the various processes in our urban environment. This includes both the direct as well as the indirect or 'hidden' carbon emissions ranging from the production of building materials to the design and construction of whole precincts. The project develops metrics and decision support tools for building designers, manufacturers, planners and developers. It aims to identify potential research opportunities to provide the best return on investment.
A comprehensive database of embodied carbon life cycle inventory data for building products and materials is the fundamental component of the project. The main objective of this part is to create a method that harmonises the life cycle data from different scales and sources by combining top-down and bottom-up approaches.
The database will be used in the 'ICM tool', which will be able to track carbon along the production and supply chains of materials and products, show the carbon outputs of industrial sectors at great detail as well as map carbon flows spatially across Australia.
The carbon emissions data will also be used in a 3D Precinct Information Modelling (PIM) tool. This will enable the calculation and visualisation of carbon emissions for specific precinct development and retrofitting projects during their planning stage.
In order to test and validate the data and calculation methods, case study scenarios of urban precincts will be prepared for modelling with PIM tools. Scenarios depend on a number of factors including cohorts of buildings, urban morphologies, demolition rate, turnover of building stock, extent of retrofitting and time span of analysis. Options for low-carbon precincts will be evaluated.
