Min Energy Peformance- 75 Energy Star Rating for EB O&M

The draft is proposing making the prerequisite for your Energy Star rating to be a minimum of 75. That is a 6 point jump from the previous requirement of a 69. That is very drastic, and a little extreme in our mind. We are working with many properties right now that are struggling to try and achieve LEED with ratings around 68-74. This would eliminate thousands of buildings, and we feel that this would greatly damage the LEED system. We understand that energy is a very large aspect of the LEED rating system, however it already greatly outweighs any other section of the rating system. Many properties’ energy star ratings are being affected by tenants installing large data centers that are beyond property control. Ratings have dropped, and properties are struggling to maintain high ratings. Not only that, but the Energy Star rating system is currently making changes, whereas effective in June 2012, properties can no longer claim data centers as a space type in an office building unless the data center is properly submetered, and actually energy data is input. Therefore, any buildings without proper submetering may be facing a dramatic drop in rating in June 2012. A building could be perfectly sustainable in every other way (great recycling rate, great water savings, etc.), but could be completely disqualified solely based on not having a high enough rating, or because they have a tenant with a large data center. Prerequisites are supposed to be considered reasonable to obtain. The points are where the real challenges should come into play, not the prereqs.

I agree Chris this is a huge barrier to the more widespread use of EBOM. Perhaps we should lower the entry barrier even further (50?) and start the points at 75. There is more discussion on this issue over at the EBOM 2012 page. http://www.leeduser.com/topic/leeduser-usgbc-guide-leed-ebom-2012-3rd-public-comment

Instead of eliminating 75% of the potential buildings that can become LEED certified (meaning minimum Energy Star rating of 75 as proposed) Why don't we institute a program like is done in LEED Homes for the home size adjustment. In Homes, if your house is over a certain number of square feet for the number of bedrooms you have, you actually are penalized with negative points that need to be made up somewhere else in order to get certified. We could allow a building with an Energy Star of 50, for example, to meet the prerequisite requirement but then require them to start with a deficit of 10 Points(we can argue about what the correct penalty should be) so that they would have to be substantially more sustainable in other areas in order to reach their certification level. This would go a long way to draw in more buildings to the program and have them be sustainable, just in a different way. Maybe there is a stipulation that they have to also show a certain percent improvement over last years performance (a Hybrid of the other option that was dropped with 3rdPC.

Great idea Rob. You could also lower the prerequisite but start the points at 75 for the credit. Not being able to get any of the 20 or so points available is a big penalty to begin with.
