Shared walls with another structure in baseline and proposed

NC-v4 EAc2: Optimize Energy Performance
posted by Christine McKinley on May 23, 2019, 1:45 pm

Hello, 

In my baseline model, can I show shared walls as exposed to exterior and then in my proposed model treat that wall as a partition? 

In other words, do I get to use the...

Energy Model AND LEED Excel sheet required

NC-v4 EAc2: Optimize Energy Performance
posted by Brandon White on May 10, 2019, 9:57 am

Are both required to be completed?  If so, one has to enter all the building information into compliant energy modeling software AND into the LEED Excel sheet?  That's ridiculous.
