The lack of reliable life cycle cost (LCC) information about water sensitive urban design assets is an often-cited reason limiting their uptake. We’ve been working with E2DesignLab and Canopy Economics and Policy to address this gap, to develop a LCC tool, focusing initially on biofilters or bioretention systems, passively watered solutions (e.g. tree pits) and permeable or porous paving.
The project team developed a process to develop and apply a LCC tool that complies with relevant Australian guidelines and standards for LCC. They also identified the LCC criteria, requirements and concepts with inputs from experts and stakeholders.
Stage 1 of the project was completed in January 2024 with the delivery of LCC tool criteria and related materials, and a prototype LCC tool with user-friendly front-end concepts.
Stage 2 of the project will further develop the prototype tool by populating it with end-user data and information and developing more functionality. This stage will also explore key questions such as data acquisition considerations, ongoing tool governance, sustainable funding models and tool ownership.

Work to date incudes building and testing the data entry form, confirming participants and populating the LCC tool with data and information. Next steps include undertaking workshops with industry experts to address the key questions above, as well as pilot testing the enhanced prototype tool with end-users.
