Guide to Sustainable Design for Architecture, Engineering & Construction

Detailed Analysis

Conduct detailed analysis to help determine improvement measures and optimize site, materials, structure, and system details for sustainable use, in keeping with the achievable performance requirements previously decided. Benefit from building information modeling (BIM) for analysis, simulation, and visualization to better inform detailed design decisions. BIM, together with integrated building energy analysis tools, helps you to better understand how changes and improvements will affect energy use, payback, emissions, and utility costs over the life of your building.
