Hi,

I am doing a LEED 2009 project. The project is in California and complied with Title 24 2016. I am trying to use title 24 to comply the LEED EAc 1. I have two questions.

1. LEED 2009 EAc1 requires using Title 24 2005, even LEED V4 asks for Title 24- 2013. But my project is using Title 24 2016. How can can use 2016 version to comply?

2. Title 24 2016 compliance report will not show energy cost. Even I select "calculate energy cost" in my software (CBECC-com). The compliance report just does not show it because the Title 24 compliance is looking for TDV energy. So how can I comply with LEED EAc1? Can I calculate manfully?

I know LEED EAc1 always has a Title 24 calculation path. Could anybody please help me? Thanks so much!

I don't think you will be able to use the report that was created for T24-2016 compliance. As far as I know LEED has not caught up to T24 2016 or 90.1-2016. You will need to create a new model using an older version of T24 for the baseline. Make sure you use a modeler that knows how to comply with LEED because there are some differences between the requirements for the compliance model and what you need to do for LEED. As you can see calculating energy cost is just one of them. I think you could use T24-2005 and the LEED 2009 standard point interpolation table. As I recall 90.-2010 and T24-2013 are considered equivalent, so you could also use T24-2013 and the point interpolation table created for ASHRAE 90.1-2010 in your LEED 2009 project.
