As cities are responsible for the majority of the global carbon emissions, there is an urgent need to turn the zero-carbon ambitions into action to respond to the current climate crisis. This thesis explores a new approach to designing for a zero-carbon future, combining urban design and computational methodologies to develop a self sufficient net-zero development. The design methodology is split into two steps: The first part of the proposed design aims to create a walkable and accessible neighbourhood at the urban level. The second part of the design methodology will focus on the computational tool that optimises the form of an Urban Superblock based on four parameters - Daylight received, Floor Area, Overshadowing and Solar energy generated. The optimised block form is used to inform the detailed design of the superblock.
