Error 1066

Under the Distribution tab at the System level of the tree, you are given the option of selecting the location of the ductwork. When the location has been set to Crawlspace, the CEC Compliance Manager requires that the total size of the crawlspace must be at least 15% of the total square footage of the home. Without a crawlspace of at least this size, there is insufficient space for the model to include the total volume of ductwork.

You have the option of changing the location of the ductwork by editing this input and selecting another location if your attic area does not meet this criteria.

If you think you have crawlspace area that is 15% or more, navigate to each exterior floor in the building tree. Review the area input for each floor. Also, click on the construction assembly and verify that you have selected a floor construction that includes a crawlspace.
