How can we improve Design Master?

Modify design load calculations and output to accommodate VAV system selection

Modify design load calculations to more accurately size/select VAV boxes. The revised calculations would take into account the heat required to overcome the additional air supplied to the VAV box that is over and above the minimum required in the heating calculations. This will help since the additional air is typically at 55 degrees and will actually add heat load to the space in addition to that required by the envelope and minimum supply air. In some cases this can be a significant load.

        This could be misleading of not done correctly, as the energy codes limit how much reheat from the VAV box is allowed.
