It is a scientific fact that it is less costly to heat or air condition a drier home than a damp one. The drier environment will have the benefit of increasing the efficiencies and performance results of the heating and air conditioning units.
A test conducted by the Department of Energy compared homes with spaces that had foundation vents versus those that had mechanical ventilation, closed foundation vents and replenishment air from the upper levels (identical to the Wave ventilation technology).The results showed that relative humidity was in the 60% range with mechanical ventilation as opposed to 79% range with foundation vents. The overall energy costs to heat and cool the entire home was 17% less KWH usage in the drier homes with mechanical ventilation as opposed to those with the foundation vents.
