Create a 3D Building Stock Model
Leads: Vidyadhar Phatak (CEPT) Rajan Rawal (CEPT), Krithi Ramamritham (IITB); Paul Ruyssevelt (UCL)
WP1 incorporates and benchmarks data sets on cities, buildings and municipal services to build a viable 3D urban model. This activity will concentrate largely on two “second tier” cities and develop scalable portable methods that can be transferred to other cities. Primary partners include Bentley Systems, Ahmedabad Municipal Corporation, and Urban Management Centre.
Administrative data from data rich ULBs, including property information from taxation records, energy data for some buildings, statistical data relating to buildings and other records describing the building stock will be assembled. These data will be supplemented with data available from other sources including, digital maps, GIS planning layers and where available, buildings data from developers or portfolio holders. Access to these data will be facilitated by the project engagement planned in RWP2. Drawing on UCL’s experience of developing statistical and detailed 3D buildings stock models [1,2] , WP1 will develop models for the exemplar cities to provide a usable tool for analysing the building stock energy performance and the impact of future interventions. This model will be tested with the ULBs to establish its benefits and the shortcomings to be address in the next stage.
In the next stage, data gathered from detailed spatial and energy monitoring in WP3 will be integrated to develop a more sophisticated model with increased resolution and greater accuracy. With partners including Bentley Systems and others iNUMBER will produce a model which is capable of integrating data from Building Information Management (BIM) and similar sources in the future so that it can grow and become more detailed as the cities are developed and redeveloped.
A user interface and dashboard will be developed for this model based on the insights gained through WP2. The model and its interface will be extensively tested with the ULBs and other stakeholders.
