20: Building System Analysis#

image

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
