When LEED EB certifying a hospital with multiple buildings that are all interconnected with tunnels, energy, water, and waste. Would it be necessary to sub meter and monitor each building or because of the interconnectedness could it be classified under a single project?
For credits like SSc4 and IEQ2.2, how should a team treat the PP? For instance, the SSc4 survey is a one time action...we plan to have a Commuting Program that can last until the end of the PP, but documentation credits such as IEQ2.2 or IEQ 2.4 are more one time measurement credits...how do these work with more program-like credits such as green cleaningGreen cleaning is the use of cleaning products and practices that have lower environmental impacts and more positive indoor air quality impacts than conventional products and practices., an action that should last from the start-date indefinitely? Thanks so much for your insight - very much appreciated!

When a credit requires a one-time event, such as the Occupant Comfort survey for IEQc2.1 or the commuter survey for SSc4, you just need to ensure that those events occur during a valid performance period. In practice, this means that these one-time events can occur up to 24 months prior to the end of a performance period.
For credits that are tracking ongoing performance, such as MRc1, MRc7 or EQc3.3, you need to provide continuous data to cover the entire performance period. Typically, these types of credits use the minimum duration of 3 months so that you don't have to spend a lot of additional time recording performance data. One reason to extend a performance period for one of these credits would be to capture the benefits of an event or activity that happened longer than three months ago. For example, if the project building held a really successful electronic waste recycling drive 5 months ago, you may want to push the start of the MRc8 performance period back to include that event and capture that data.
A good management best practice is to have a discussion early in your project to map out anticipated performance periods for each credit you think will be attempted. Remember to ensure that the performance period end dates for all attempted credits fall within a shared 30-day window!
Hi, I was reading through LEED EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. and it is indicated the methodology is applicable for comercial and institucional buildings. At the moment, I´m dealing with 2 projects as follows:
First project is On-campus and several buildings. One of them is a Warehouse. Is the warehouse also candidate to apply for LEED EBOM certification or we should exclude it?
Second project, it is a manufacturing plant integrated with and office building plus a attached methalic production building? Is it possible to asses the production building (factory) under LEED EBOM?
Thanks in advance for your help,

If the warehouse has at least one occupant it may be eligible for EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems.. Check the MPR forum here. I can't see a reason the production facility would not be able to apply for EBOM. Again check the MPRs.
(1) Are there any case studies on a multi-family residential project that achieved certification in the LEED-EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. system?
(2) Do all of the individual tenant units have to be included in the certification? How should you handle necessary improvements (i.e water reduction, air filters, etc)? Do you have to retrofit each apartment, only a sampling, or have a phasing plan for implementation? Any help is appreciated. Thanks.

To your second question, I'm fairly confident that the answer will be yes - individual tenant units would be included in just about everything. There are some flexibilities around purchasing, but the hardware/systems type elements you note are almost certain to be required in every apartment, top to bottom. Sampling or phasing or partial implementation is rarely feasible in EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems., with a few exceptions.

Lance, if you're still following this question: We have been looking into EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. for a multi-family residence. The project may or may not happen, in part due to the unique challenges of MFR properties under EBOM -- particularly for a property that was not originally built to high green standards.
Regarding your second question, as Dan notes, there are apparently some flexibilities around the MR purchasing credits. There are a couple of inquiries in USGBC's Interpretations database which confirm that in dorms and MFRs, the purchasing credits are possible based on (1.) building purchases and (2.) providing educational guidance to residents on how they can make their own purchasing decisions with sustainability in mind. See inquiries #5133 and #5134.
There are few case studies available because there are so few EB certified multi-family projects. A month ago, I downloaded the USGBC's current spreadsheet of certified/registered projects and filtered the data for EBOM projects (all versions) that said they included "multi-unit residence" in their project type(s). Only 65 or 70 "multi-unit residence" projects have ever been registered for any version of LEED EB; only five have been certified, at least two of which were university housing (one of the five is confidential). The university housing may not have faced some of the typical challenges faced by multi-family residences (e.g. distributed HVAC and DHWDomestic hot water (DHW) is water used for food preparation, cleaning and sanitation and personal hygiene, but not heating. systems; individual utility billing, etc.), so there are only two, possibly three, true multi-family projects that have ever been certified. Both of those appear from their websites to be mid- to high-end properties that were constructed relatively recently as high-level NC certified projects. Only one of those is certified under EBOM 2009. (Of course this filtering may have missed some projects, but it still serves to illustrate how few MFR EB projects there actually are.)

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?

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.
