Lifecycle evaluation of building sustainability using BIM and RTLS

The purpose of this research is to provide a lifecycle building sustainability evaluation method to guide different stakeholders in how to apply sustainable practices and maintain the expected sustainability. Building Information Modeling (BIM) is selected to be a platform to integrate all the information to improve interoperability. Green standards are embedded in the BIM model and a rule-based system is developed to automatically evaluate the design and the building performance. Data are collected by using a Real-Time Location System (RTLS) and are used to update the BIM model. The as-built model is checked to see if it matches the sustainability aspects regarding the construction processes. During operation, energy consumption data are collected and analyzed. The performance of the building is checked to see if the designed features reach the sustainability goals. By integrating the BIM, RTLS, and other information, a prototype system of lifecycle sustainability evaluation is developed and tested.
