BIM Use: Building Systems Analysis
System Analysis
A process that measures how a building's performance compares to the specified design. This includes monitoring how the mechanical system operates and how much energy a building uses versus the predicted model.
Other aspects of this analysis include ventilated facade studies, lighting analysis, internal and external CFD (Computational Fluid Dynamics) airflow, and solar analysis.
| Potential Value: |
|---|
- Ensure building is operating to specified design and sustainable standards (Performance Verification).
- Identify opportunities to modify system operations to improve performance.
- Create "what if" scenarios to change different materials or setpoints to show better or worse performance conditions.
| Resources Required: |
|---|
- Energy Analysis: Software like IESVE or EnergyPlus.
- CFD Analysis: Software like Autodesk CFD or Ansys.
- Lighting Analysis: Tools like ElumTools or Dialux.
- Building Management System (BMS) data logs.
| Team Competencies: |
|---|
- Ability to understand and manipulate CMMS and building control systems with the Record Model.
- Ability to understand typical equipment operation and maintenance practices.
- Ability to manipulate, navigate, and review a 3D Model.
- Knowledge of building physics and thermodynamics (for analysis interpretation).
