Appendix B-2: BIM Use – Building Systems Analysis

Building Systems Analysis

Description:
A process that measures how a building’s performance compares to the specified design. This includes how the mechanical system operates and how much energy a building uses. Other aspects of this analysis include, but are not limited to, ventilated facade studies, lighting analysis, internal and external CFD airflow, and solar analysis.

Potential Value:

• Ensure building is operating to specified design and sustainable standards
• Identify opportunities to modify system operations to improve performance
• Create a “what if” scenario and change different materials throughout the building to show better or worse performance conditions

Resources Required:

• Building Systems Analysis Software (Energy, Lighting, Mechanical, Other)

Team Competencies Required:

• Ability to understand and manipulate CMMS and building control systems with Record Model
• Ability to understand typical equipment operation and maintenance practices
• Ability to manipulate, navigate, and review a 3D Model
