At the top level of the Building Tree, in the Residential tab, you can select from a variety of different ventilation cooling systems, including a Whole House Fan. Once the type of ventilation cooling system is selected, at the System level of the Building Tree, in the Residential tab, input the total CFM for your fan, along with the total wattage. A whole house fan will only be recognized on a project that has a ventilated attic, and whole house fans will receive no credit in multi-family occupancies per the CEC guidelines. Note that the CEC maintains a list of approved whole house fans with specifications on their website.
