For Title-24 compliance purposes, the CEC requires cooling to be included in the proposed building model. When modeling a low-rise residential project, the software will include a default cooling system when calculating the results. This system is defined automatically and you have no option to change the definition of the system. When modeling a nonresidential project, you are responsible to define the default cooling system for your project, you cannot leave it undefined. This would be a code minimum efficiency cooling system included as part of your model.
If you find your cooling numbers are causing the building not to comply, review your window inputs and in particular the SHGC since that will affect the cooling usage of the default system.
