AN INNOVATIVE TOOL FOR OPTIMISED DEVELOPMENT ENVELOPE CONTROL (DEC) ANALYSIS AND SCENARIO BUILDING IN DIGITAL TWIN

Abstract. Despite the advancements in Planning Support Systems (PSS), Geographical Information Systems (GIS), and multi-dimensional building and city modelling, we found that they are not within the factual urban planning and design practice and often do not generate expected knowledge and wisdom. In addition, there is limited application of computational generated data and visualisation in the current statutory and strategic planning processes. For example, the planning and design rules and guidelines for a compact city development need to be examined and communicated to the professionals and the community to ensure that they are fit for purpose and address the users requirements. However, the planning rules are communicated through texts and diagrams, which are very difficult to understand and there is a risk of misinterpretation, uncertainty, and dissatisfaction in urban development processes. This research leverages the emerging technologies such as Digital Twin to develop a scenario-based PSS to consider the planning controls protecting the public’s interest while optimising economic and spatial yield.
