Has anyone else noticed that some of the ACP documents state that international projects can't use Energy Star for energy benchmarking or energy performance? This is like changing the rules to the game in the middle of the game. The change will have major impacts on market transformation and the time, cost, and ability of international (in my case European) projects to earn any level of certification.

i haven't seen this per se - where is this documented? would be very keen to see this, since this would potentially affect us as well (haven’t run the numbers yet).
my understanding so far has rather been that international projects are now ALLOWED to use Option 2 to demonstrate compliance, which may make it a whole lot easier for some projects, while maybe not for others? international projects have never been able to use the ES PM other than for benchmarking, providing a score rather than a certificate.

Jutta,
The documentation is constantly changing and conflicting, but the original ACP EBOM documentation released around October 9th states the following:
CASE 1. Projects Eligible for Energy Star Rating-This CASE is not available to Projects outside the U.S.
CASE 2. Projects Not Eligible for Energy Star Rating OPTION 1-This CASE is not available to Projects outside the U.S.
CASE 2. Projects Not Eligible for Energy Star Rating OPTION 2-Note for Projects Outside the U.S. - Projects outside the U.S. can use Option 2 but are limited to Option 2B or 2C, as outlined in the LEED Reference Guide for Green Building Operations & Maintenance, 2009 Edition.
The original LEED EBOM manual states this:
"For building types covered by ENERGY STAR but located outside the United States, use Case 1 to obtain an ENERGY STAR rating. The Portfolio Manager tool provides a list of locations outside the United States, but it is not complete. If the location for an international project is not listed, consult ASHRAE 90.1-2007 Appendices B and D to determine a comparable US city."
The issue is that there is no national energy data available outside the US, like CBECS. See the excerpt from an EU energy research committee.
"Breakdown of Energy Consumption
Information on the average breakdown of total energy consumption for different end-uses in nonresidential buildings is not available for most countries or is limited for the other countries. In cases when information is available, most of the data refer to the last decade.
Breakdown of Energy Consumption in Different End-Use Buildings
Information on the average breakdown of total energy consumption for different end-uses in nonresidential buildings is not available for most countries or is limited for the other countries."

The problem with Options 2B and 2C is the following:
"Enter at least 3 consecutive years of historical energy use data into Portfolio Manager, in addition to the current year's data."
ACP Problems:
OPTION 1. Benchmark Against Comparable Typical Building CASE 1. National Energy Data Available - No Data available
OPTION 1. Benchmark Against Comparable Typical Building CASE 2. National Energy Data Not Available - Finding three typical, comparable buildings with permission to use their energy bills. Requires 12 months of data.
OPTION 2. Demonstrated Energy Efficiency Improvement-The building must have at least four consecutive years of site energy data.
The certification process for some buildings just jumped from 12 months to 48 months or longer for buildings that are a few years old but didn't LEED certify previously....

thanks for the posting and this doesn't sound very encouraging at all!
i hadn't seen these and hadn't actually delved into these, since from all i heard at toronto and from all i read in the documentation guidance and on the usgbc website is that following the ACP remains optional: we may either use the ACP or the original credit requirement. maybe a formal clarification from international@usgbc.org would help sort this out?

Jutta,
I plan on submitting a rather lengthy document to the USGBC once I review all of the conflicting documentation detailing my view on the impacts.
The current ACP document is totally different from the previous form. It would be nice if they would put version numbers on documents rather than October 2011.

Good news. Looks like it was just a mix up.
"Thanks for your question about EAp2 and EAc1 for EB projects outside of the U.S. The language stating that Case 1 was not available to projects outside of the U.S. was erroneously included in the Rating System with ACPs. The case IS available to projects outside of the U.S. and the box stating otherwise has been removed from the Rating System."

Thanks for posting that response, Eric. Also, thank you for noticing that the language is still included for EAc1. We will work to remove that language as soon as possible and update the rating system to reflect this.

Just to say, I've completed the process now with Energy Star for an EBOM project in Vietnam. A few small bumps but I received my rating and the energy intensity score as required. I did get confused due to some aspects of the Energy Star site. They said that my project could apply for the Energy Star Rating, but following that link, I quickly found that it is really only possible with US projects, or US Government-owned projects. It must be signed off by a US-registered architect or engineer. LEED on-line reponses clarified: What you need for LEED is only to generate the energy intensity and the comparison with other projects and that is done automatically and can be documented in a PDF format called an SEP, which is provided via another link on the Energy Star summary page for your project. This SHOULD also show the carbon emissions, but like others I found that it didn't show up on the SEP so I used a screen shot of the relevant part of the summary page to record the CO2 data. By sharing data with the GBCI I assume the rest is straightforward. The only other quirk I noted was that for some reason choosing my final data month didn't work (February), I had to choose January as my end month. I still don't know why, but this allowed me to generate the report as required. I have no idea if that last quirk was temporary/to do with my data/or otherwise, but its effect was minor. Hope that helps.
