LEED Embedded Building Information Modeling System

Zhang, C. / Chen, J.

This paper focuses on a lifecycle evaluation of building sustainability following a Green Building standard—LEED. The purpose is to provide an efficient and effective way to guide the different stakeholders involved in the building lifecycle performance properly and realize sustainable practices, which includes the owner, designer, contractor, manager, and end-users. Building Information Modelling (BIM) is selected to be a platform to integrate all the information to improve interoperability. Starting from planning and design phase, LEED standards will be embedded in the BIM model to evaluate the building design. A rule-based system is developed to automatically evaluate the sustainability and provide flexibility for different scenarios to gain better green grade. This BIM model will be also used during the construction phase and data collected from the construction site will be integrated and the model will be updated in real-time using an RTLS system. The as-built situation will be checked to see if it matches the as-designed sustainability aspects. During the operation phase, energy consumption data are collected and energy consumption patterns are analyzed based on the spatial division in the building. The real energy performance of the building can be checked to see if the designed features reach the sustainability goal.
