The Delivering Net Zero in Use Toolkit has been developed to complement ‘Delivering Net Zero in Use: a guide for architects’, which was first published in November 2022 as part of AHMMs Knowledge Transfer Partnership with UCLs Institute for Environmental Design and Engineering.
The toolkit was developed in response to a need to coordinate and visualise a projects carbon data across all stages and disciplines of a building project. Users can input predicted carbon data from multiple consultants into the Excel based programme, which can generate two graphic outputs:Â an interactive waterfall diagram which shows carbon emissions, and a carbon square which ranks carbon alongside time, cost, and quality drivers. The Toolkit can also identify where missing data is required and set targets for the gaps based on best practices.
It was initially designed to be used for our own large, complex, mixed-use developments, which often have multiple variables, changing stakeholders over a long period of time, and tenant changes, to measure the collective impact of these factors on embodied and operational carbon.
The tool has now been developed as an open-source tool that can be used for buildings of different typologies, and it enables the entire client and consultant team to look at information, collectively understand the impact of the individual disciplines and develop realistic targets together.
Processing the data in this way allows teams to have a holistic view of a project’s cradle-to-cradle carbon impact, and, importantly, provides the opportunity to assess how iterative changes to a building’s design, delivery, operation, and demolition, can optimise its environmental impact. The tool can be used to take into consideration the environmental impact of CAT A and interior fit-out removals associated with lease changes in commercial and mixed-use developments
