CD-phase modeling

Beyond 30% reduction in energy; traditional process has limitations

Designer’s LEED-based tunnel vision

INTEGRATED MODELING INTEGRATED MODELING

The AIA’s experience with the American Society of Heating

Refrigerating and Air-Conditioning Engineers’ (ASHRAE) advanced energy design guide suggest that although some reductions are prescriptively achievable (i.e. through the use of a checklist), as one

exceeds a 30% reduction and moves toward even greater reductions, complex interactions of systems and context must be taken into

account. Integrated processes are being acknowledged and encouraged in sustainable ratings systems such as LEED.

LEED is a tool or guide…not a comprehensive answer
