Hi All,
I am working on a warehouse project targeting at LEED 2009 certification. I need to fill up the v2009_Minimum Energy Performance Calculator_v06 as part of the submission (if I understand right?). Now I have a few questions regarding this excel sheet. Really need your help, thanks!
1) In the tab of Shading and Fenestration, it requires to fill up the Above grade wall area and vertical glazing area for each orientation. Does anyone know where I can extract these numbers from? I did not find any numbers on the final BPRM report.
2) In the tab of Performance Outputs_1, it showed me quite a few issues, most of which are related to exterior lighting. There is no exterior lighting designed for this project, so I did not apply any exterior lighting for both baseline and proposed models. However it said that 'the baseline/or proposed exterior lighting equivalent full load hours differs by more than 5%, which is unexpected'. Does anyone have any experience in such issue? Many thanks in advance!

You are not required to use it. You can request that GBCI change the forms in LEED Online to the older ones or you can simply upload the older forms. Make sure to use the section 1.4 spreadsheet with the v5 of the form. Don't use the v6 of the form and the old section 1.4 tables.
1. Not sure where you get these numbers in IES-VE. The reporting is quite limited so you will have to dig some. I would contact IES-VE.
2. There are problems with some of the issues raised in that section of the spreadsheet. If an issue raised does not seem applicable just enter NA. Equivalent full load hours are the energy use divided by the demand. It is a check used to make sure that the schedules for the operation of electrical equipment appear reasonable.

Hi Marcus,
Many thanks for your quick reply!
Could you please also advise where to download the section 1.4 table with v5? I only found one updated in jan 2014 and unsure of that is the right one. Thanks.
Could you also advise what documents are required to submit as part of EAp2 and EAc1? To my undestanding, it should be the Section 1.4 table and Building Performance report from IES. Is that right? Do I need to submit anything else? such as Energy model? Many thanks.

The January 2014 version is the most recent.
That sounds right to me. IES is pretty weak on reporting especially on the HVAC side so it can be a good idea to show modeling inputs for HVAC through screen captures or other means. This is especially the case if you are doing anything slightly anomalous. Do not submit the model file.

Hi Marcus,
Many thanks for your help!
May I ask why v6 is not preferred in this case? I found that v6 was much more convenient, for example it allowed me to use SI Units. Many thanks!

There is nothing wrong with the v6 form beyond some remaining functional issues. If you use the v6 form use it with the Minimum Energy Performance Calculator. If you use the v5 form use it with the Section 1.4 Tables. The problem is when you mix this up and use the v6 form with the Section 1.4 Tables. In that scenario you will not be providing sufficient information for the review.

The wall and window area by orientation can be obtained by going to ModelIT->Model Report and selecting Above grade glazing % under Section B: Data Assignment.
Because there is so much that you could take a screen shot of to report the HVAC inputs, I generally wait until I get review comments to provide any more detail than what is in the BPRM report or table 1.4. Once there are review comments I can provide screen shots of the particular system they have questions about. After all, the baseline sizing and efficiency requirements are predefined in the baseline prototype systems. I would provide screen shots with explanations of anything out of the ordinary that could cause questions in the review.
