Use of building information models in simulations

The transition to Building Information Modeling (BIM) represents a substantial shift from existing business practices in the architecture, engineering, construction, and facility operations (AECO) arena. While the move from drafting to computer aided design (CAD) sought to automate an existing business practice, successful BIM virtually builds a structure first. Similar to the virtual prototypes in the manufacturing industry, now AECO designers and maintainers can use these virtual models for evaluating various courses of action for improved design and construction. This is especially true in the area of sustainability analysis for design factors such as day-lighting, climate control, and energy usage. This paper will address new emerging business processes stemming from BIM simulations.
