NC-2009 EAp2:Minimum Energy Performance

Which ASHRAE & LEED should I base my simulation on?

Hello, I have a problem with choosing a basis for my simulation. I have a building that was designed in 2015 and is about to be build. I need to perform simulations for "Optimize Energy performance" credit... In LEED 2009 it's said the baseline building should be prepared according to Appendix G Standard 90.1-2007. But there were later also versions 90.1-2010 and 90.1-2013 (The building was designed in 2015!) Should I then follow direct instructions in manual and prepare baseline model according to 90.1-2007 or rather 90.1-2013, because this is the most appropriate for my building? Please let me know, in case contact via my mail olafdybinski@gmail.com I would be very thankful for your answers. Best regards, Olaf

The baseline is determined by the version of LEED you register under, not the local code or the year it was designed. If the project is registered under LEED 2009 then you use 90.1-2007. You can also use 90.1-2010 and there is a alternative point threshold if you do so published in a LEED Interpretation. If registered under LEED v4 you use 90.1-2010. I have not yet seen anything about using 90.1-2013.
