Abstract

Recent discussions on Geodesign reoriented Geographic Information System (GIS) and Planning Support System (PSS) professionals to be more design-focused. The paper introduces a GIS-based energy performance and carbon emissions assessment for urban design that is a forward-looking modeling approach to address the issue of how the scientific-based analysis articulates design. Seven global cities and their central urban districts are chosen for mapping the urban form structure, energy performance, carbon footprint and solar availability of the built environment. The relationship between urban form and its energy and carbon efficiency is explored through benchmarking their performance. A sample urban block modeling is conducted and an interventional design approach is taken for showing how new urban form and internal organization of cities matter and affect the energy and carbon efficiency. Urban design is seen as a tool to synthesize complex factors for projecting a forward-looking future urban system.
