The DOE has decided to pilot and implement a commercial building Asset Rating system that will evaluate and score the physical characteristics that define the energy efficiency of commercial buildings. This new DOE “AR” will be in addition the EPA’s ENERGY STAR program which scores the actual energy consumption of commercial buildings.
The DOE is asking for feedback from interested parties.
Here are the key issues that I have commented on:
• Can buildings that are performing poorly (with low ENERGY STAR scores) publicize a good Asset Rating score and hide their poor performance? Or should buildings claiming high Asset Ratings be required to disclose how they are actually performing?
• Should the new AR system use the ENERGY STAR scoring system (0 to 100) or a different one?
• What building attributes should be on the input worksheet and how should they be weighted in the final score?
If the right building attributes are selected by the DOE this could be a transformative event for the commercial building industry. If the wrong building attributes are selected or if they are weighted incorrectly, we could have another green point system that distracts young architects and inexperienced building managers.
