This great presentation, worth the nine minutes, it raises the discussion about LEED, and green building rating systems by Mr Henry Gifford. It reminds us that LEED is a great marketing system, yet the study shows that LEED rated buildings actually use more energy than non-rated buildings.
So where do we go from here? Could LEED, or for that matter any green rating system, be the driving force for more energy efficient buildings, perhaps that is the future intention? LEED O&M is the building operating rating system, however if your building is already certified as a LEED Gold building, why would you consider another certification process?
What is needed measurement, and publication of the annual resource consumption (not only electricity and fuel, but water consumption too because cooling towers are widely used). Once the information is in the public domain the market has the opportunity to choose the lower cost, and reduced environment impact buildings. Building responsibly choosing recycled materials, and those from sustainable resources is a key part of green building, but it is not the only metric.
