NC-2009 EAp2:Minimum Energy Performance

Alternative to Table 1.4

When submitting energy models to NYC we have to fill out a form called an EN-1 that is very similar to Table 1.4 and provides the same information. Can we provide the EN-1 in place of Table 1.4? Currently we are essentially filling out the same form twice. Has anyone been successful with submitting an alternate form in place of Table 1.4. Did LEED require any additional documentation? The model that we are hoping to do this for is registered under v3 and we would using an ASHRAE 2010 baseline as per the LEED interpretation ID#10421.

Table 1.4 will not work at all for 90.1-2010 since it is based entirely on 90.1-2007. For LEED you will need to use the Minimum Energy Performance Calculator (MEPC). This combines the majority of information from the prerequisite form and the Section 1.4 tables. If the EN-1 does indeed include all (meaning everything) the information in the MEPC then you could submit it as a substitute. My guess is that it would not include everything, the reviewer may not be at all familiar with it, and using it would likely result in your having to provide responses to may additional review comment caused by the confusion that would be created. So it may save you some time up front and then cost you time later.

HI Marcus, Where do I find the referenced Minimum Energy Performance Calculator (MEPC). I searched in the credit reference library for the prerequisite EAp2 and could not locate it. Is there any other reference library? Thanks, I think I found it. Is it the MEPC _v08 updated April 14, 2017? I'm doing a healthcare project and the form directed me to the resources tab in the local credit library, but it is not there. I found it by Goggling it outside of LEED online and it gave me the link to location in USGBC site. Thanks

That is it. I have found what you discovered - it is often better to search for something on USGBC's web site through Google than trying to find it on their site or trying to search on their site.
