AT THE END OF THIS PROGRAM, PARTICIPANTS WILL BE ABLE TO:
• UNDERSTAND THE DOMINANT INFLUENCE OF CLIMATE ON THE DESIGN OF SMALLER (I.E., SKIN-‐LOAD DOMINATED) BUILDINGS
• LEARN THE QUANTITATIVE DESIGN OPPORTUNITIES BIM OFFERS FOR SUSTAINABILITY
• IDENTIFY THE APPLICABILITY OF A BIM WORKFLOW TO SKIN-‐LOAD DOMINATED PROJECTS
• DISCUSS SPECIFIC CASES WHICH DEMONSTRATE BIM'S APPLICABILITY TO THE OPTIMIZED DESIGN OF HIGH-‐PERFORMANCE BUILDINGS

WHY BIM?
• EFFICIENCIES
• NIST: CONSERVATIVELY, $5.3 BN COST TO DESIGNERS AND BUILDERS IN CAPITAL FACILITIES INDUSTRY IN 2002.
• REDUCTION OF ERRORS• INHERENT COORDINATION• VISUAL AND AUTOMATED CLASH DETECTION
• INTEGRATION OF DESIGN AND PRODUCTION• COLLABORATIVE OPPORTUNITIES• INCREASED COMMUNICATION AND DISCIPLINE
• OPPORTUNITIES FOR IMPROVED BUILDING PERFORMANCE

• BIM IS NOT A RELIABLE PREDICTOR OF REAL-‐WORLD PERFORMANCE
INFORMED DESIGN DECISIONS
• BIM CAN BE A USEFUL COMPARATIVE DESIGN TOOL
• WHAT ABOUT ENERGY MODELING?

MATERIAL TAKEOFFS

• CLIMATE LOAD DOMINANCE IS INVERSELY CORRELATED TO BUILDING SIZE.
• THE DESIGNER CAN LEVERAGE BIM'S BUILT-‐IN GEOMETRICAL AND PERFORMANCE DATA ANY TIME IN THE DESIGN PROCESS, THE EARLY THE BETTER
• MANY WELL-‐ESTABLISHED DESIGN GUIDELINES CAN BE BIM-‐IMPLEMENTED FOR BETTER DESIGN DECISIONS IN HIGH-‐PERFORMANCE BUILDINGS
