Greetings,

We are to create an energy model for a 8 floor building, which will be partially hotel, partially family apartments.

As per table G3.1.1.-3, for the above categories (specified as Residential) the Systems should be System 1 PTAC/PTHP.

Is this System 1 applicable only for low rise residential buildings? Is it possible to apply also System 5, which corresponds to the project building ?

Thanks
