Goal Setting and Design• Pick the right team
– Make sure everyone speaks the same language• Identify project goals/facilitate a design charrette• Identify a standard
– Ensure that goals/requirements make it in the drawings/specs
• Look for opportunities to add value without adding cost
Construction, Verification, and Testing
• Pre-construction meeting• Mockup unit• “Don’t expect, what you don’t inspect.”• Diagnostic testing -blower door testing,
duct leakage, flow testing
Project Feedback Loop• Don’t be afraid of lessons
learned meetings– “an expert is someone who remembers their
mistakes.”
• Maintenance staff should be involved in all aspects of the process/project.
• Measure what you project
Measure What You Project“There is nothing so horrible in nature as to see a beautiful theory murdered by an ugly gang of facts.” -Benjamin Franklin
