Hi, I was wondering where I would be able to get a copy of the LEED EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. presentation slides?

Yes, we hear you and are working on posting a copy of the presentation (in addition to the video which is posted above). Dealing with a technical constraint relative to the large file size.

On p. xx in the GBOM Ref Guide, the asterisk in Table 1:Sample Performance Period declares "All performance periods must end within the same 7-day interval". However, Jenny stated that this has been changed to one month instead of one week. Could someone post a link to the document that states this change? Is it in a document addenda from USGBC or GBCI?
I have found the following information on the overlaps of performance periods from the different versions of LEED for Existing Buildings:
EB v2: all performance periods must end within a shared sixty-day window… EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems.: all performance periods must overlap and terminate within one week of each other...
EBOM v3: all performance periods must overlap and terminate within 30 calendar days of each other…
Have I missed an update to LEED-EBOM to extend the overlap?

That matches up with my understanding of the current overlaps.
Thanks for the response. If it wasn't so late in the game, I would change to EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. v3. I just hope we can pull off the one week overlap -- it's going to be tough.
I just received an email from the USGBC stating they will be changing EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. 2008 to a 30 day window as well.
Documented benefits as a result of LEED for Existing Buildings
I am looking for data that shows the benefits (triple bottom line) for buildings that have achieved the LEED for Existing Buildings certification. I've heard that the owner can expect a 30 to 50% return on investment and that a LEED EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. Certified or Silver has a 2 to 3 year payback.
Most of the cost/benefit data that I have found is for new construction. I know I can look at individual case studies, but wanted to see if there were any consolidated results. Does anyone have any suggestions?

You raise a good question, the results you quote sound aggressive but are not necessarily out of line with published commissioning data. I would like to see this data for LEED EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. certification as well.
Evan Mills's work "Building Commissioning, A Golden Opportunity for Reducing Energy Costs and Greenhouse Gas Emissions" publishes data that show averages for commissioning existing buildings typically show energy saving of 10-15%, average commissioning costs of $0.46 and payback of 1.8 months. All of which are for commissioning, not necessarily LEED certification.

Karen - I dare say that if you find any reliable data like this, you instantly become a hero to the EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. community. Having wrestled with this very issue since the beginning of EB, often in collaboration with the USGBC itself, I'm keenly aware of the difficulty in creating a useful analysis as it relates to existing buildings.
The two problems are this: 1. Different starting points. Some buildings enter the EB process in fantastic condition and use the rating system as a verification tool. Others enter in terrible shape and use the system as a road map to improving operations. As you can imagine, these two buildings would have radically different costs and benefits associated, to a degree that they become apples and oranges. When one building achieves certification for $50k, and another for $2 million, its a tough data set to manage.
2. Cost assignment. Drawing lines around an EB project is extremely difficult. If a building replaces a chiller as part of their EB project, how should that cost be assigned to EB? The entire cost of the chiller? The marginal cost relative to a less efficient replacement chiller? What if they were planning to replace the chiller regardless of EB? There are ways to answer all these questions, but getting survey respondents to answer them consistently is extremely difficult.

Dan, thanks for your insight. I agree. It will be difficult. But, it is extremely important that we all understand the documented benefits of LEED EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems.. We have over 70 billion sf of commercial building space existing today. Much of which could improve financially, environmentally and socially by following the LEED EBOM certification process. Building owners need this data to make informed decisions. I had thought about the IO credit and wondered how much data USGBC had received on completed projects. A colleague and I are "mining" some data on several completed existing building projects. I'll let you know what we find.

great presentation
a copy of the slide would be helpful.
Copy of the Presentation
Yes, a copy of the presentation would be very useful in explaining the process to my clients.

Performance Period - end dates

Tristan Roberts replied Editor – LEEDuser, BuildingGreen, LLC Jun 07 2010
Yes, see the LEED addenda from USGBC issued on 12/2/2009. You can find the document on this page, or download it directly here. Look on page 2.

All that being said, USGBC/GBCI is collecting some interesting data via the 'Documenting Sustainable Building Operations Cost Impacts' credit in the IO section and perhaps they will soon make magic from those numbers.
