This technical investigation presents the precinct information (PIM) data schema. The schema is an extension of the current IFC data schema that is used widely for building works. Apart from buildings, precincts also contain infrastructure objects such as roads, railways, bridges, tunnels, and outdoor civic spaces that contribute to the overall carbon impact and therefore need to be modelled.
PIM considers buildings and infrastructure equally as “built facilities”. Additionally, PIM provides a means to model vegetation that will allow for mitigation factors to be determined when assessing urban heat island effects. The proposed extensions to IFC are defined in a way that generalizes, but does not break, existing IFC functionality.
Rapid global urbanization and the increase of the Urban Heat Island (UHI) effect make urban cooling a necessity as well as an opportunity to increase the liveability and amenity of cities. This review is a scoping study of the relevant worldwide UHI mitigation/adaptation...Read more
The 2020s are predicted to be a decade of transformation for urban mobility. There are at least six forces that are expected to disrupt the urban mobility landscape. From self-driving vehicles and the sharing economy, through to vehicle electrification, mobile computing, the...Read more
Financing the upfront costs of energy efficiency and renewable energy projects in buildings can be a significant barrier to the expansion of sustainable, low carbon buildings, despite this being a low-cost option on the carbon abatement curve. Systematic literature on...Read more
Precinct Information Modelling (PIM) describes the process of creating a 3D digital model at the scale of a precinct, defined as any area of the built environment that is of interest for some practical purpose.
The work undertaken in the CRCLCL PIM Project (RP2011) was presented at an Industry Symposium on 15 September 2017. The aim was to demonstrate how Precinct Information Modelling (PIM), based on an open information exchange standard, can enable more effective urban planning, design and management at a precinct scale. The objectives of the event were:
This technical investigation canvases a range issues concerned with the development of a PIM Object Library, specifically to address carbon management, though the principles could be applied within a broader context. It deals with:
