Research at the CRC for Low Carbon Living has led to the development of a range of on-line and desktop tools that facilitate a wide range of tasks including various aspects of precinct assessment as well as energy and emissions modelling. Together these make up an extensive suite of decision-support and modelling tools that can assist planners, developers, builders, architects, quantity surveyors and many others associated with delivering a more sustainable built environment. All the CRC tools are made available free of charge and in most cases open-source.


Integrated Carbon metrics

The Integrated Carbon Metrics (ICM) project built knowledge about both the direct and indirect carbon emissions in the building process, to better inform those making decisions about our future built environment. Carbon accounting tools that can be scaled to the building, precinct or city level have been developed, to provide a complete picture of the carbon lifecycle in the Australian built environment.

Embodied Carbon Explorer tool

The Embodied Carbon Explorer (ECE) tool rapidly evaluates embodied carbon on a precinct-scale project and shows in detail how different industries contribute to carbon emissions.

The ECE is hosted on the Industrial Ecology Virtual Lab and managed from the UNSW.  Register for an account and to access help and support at



Precinct Carbon Assessment tool

The Precinct Carbon Assessment (PCA) tool examines the whole life cycle of carbon emissions on a precinct scale and enables the exploration of different low carbon scenarios, calculating their carbon impacts.

Urban Heat Island tools

Urban Heat Island Decision Support tool

The Urban Heat Island Decision Support tool (UHI-DS) provides decision-support for assessing the urban heat implications of development proposals. The tool enables decision makers to determine what the most effective urban design interventions are in reducing air temperature in precinct-scale developments. It has been applied initially to three exemplar precincts (Parramatta, Green Square and Macarthur Heights in Sydney) to assist local governments and developers to effectively mitigate extreme heat conditions.

Urban Heat Island Mitigation Index & Urban Heat Vulnerability Index tool

The Urban Heat Mitigation Performance Index (UHMPI) supports local governments, developers and urban planners to mitigate extreme heat, complementing, the UHI-DS tool. The UHIMPI provides mitigation strategies and alternatives to support building planning, public realm and community program planning decisions. 

It is also linked to the Urban Heat Vulnerability Index (UHVI), allowing users to query vulnerability the information of a population to support UHI mitigation decision-making. The UHVI was developed using the IPCC methods and comprises three sub-indexes: Exposure, Sensitivity and Adaptive Capacity.
