A climate change simulation framework and workflow for assessing and informing intelligent green building adaptation design is proposed. Applying the simulation workflow to an existing green building as an example of adaptation design, we show how the energy requirement is modelled and specified for green building technologies to mitigate summer overheating while minimizing carbon emissions. To attain fuller energy requirement profiling for intelligent green building adaptation design, further simulation study into other seasonal conditions is required. This will inform potential links with smart grid development to implement new capabilities of modelling intelligent green urban neighbourhoods and smart cities.
