Building Information Modeling (BIM)

What is it?

Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility, and essentially results in a model based design and construction process. It serves as a shared knowledge resource for information about a facility, forming a reliable basis for decisions throughout the life cycle of the project. Currently, numerous organizations are undergoing initiatives to develop a National BIM Standard.

BIM inputs during the design phase allow collaboration among team members, ideally to optimize solutions for building performance. A BIM allows for timely feedback concerning the effectiveness of daylighting solutions, sustainable materials, and the energy efficiency of systems.

BIM can be particularly useful for high-performance or "green" buildings. "For example, BIM could be used to track LEED credits. As BIM continues to develop, technology providers will need to improve its ability to address the sustainable design and construction demands of the industry.

• 77% of BIM users are involved in at least a moderate number of green projects.
• 57% say BIM is at least moderately helpful in producing green projects.
• Half of respondents indicate that a LEED certification tool would be beneficial in motivating them to use BIM on green projects. Autodesk-Revit White Paper
