- the higher the LEED rating, the better the energy performance
- there are wide disparities between modeled (predicted) and actual performance
- labs and other buildings with high process loads use twice as much energy as predicted
This study plows new ground and moves in the right direction. But future studies should show conclusive justification for LEED in the cost arena. If LEED is conclusively justified, it's a no-brainer. If a no-brainer, everyone will design and build according to LEED tenets, so that the need for LEED, and the corresponding costs to administer it, go away.
