3D, BIM and IoT: scaling from buildings to (smart) cities
The creation of national BIM strategies typically comes with sound business cases. In the case of the UK BIM tasks group’s initiative, the goal is to save 20% of capital as well as operational expenditure over the lifetime of public buildings through the adoption of BIM and sharing of building information along the building lifecycle. With more and more BIM data being shared, there is the concept of scaling up BIM from individual buildings to a city level. From am geospatial perspective the creation of 3D city models for entire cities is actively being done in many countries. This paper discusses practical experience on combining surveying BIM as well as Internet of Things into a data integration and sharing environment that will allow simulation and performance analysis for collections of buildings as well as entire cities in order to optimise the any building portfolio. For example, integrating energy and environmental performance sensors into allows building operators to monitor the performance of a building and optimise costly operational criteria such as air conditioning, heating or even the utilisation of meeting rooms. Examples from Ordnance Survey International’s smart cities and BIM practice in the UK and internationally are given to illustrate how build environment data can be integrated.
