My house is one year old in May. We had opted for spray foam insulation. Contractors promise was that the energy savings pays for the upcharge within 5 years. My question... How is this more efficient than batt insulated house? Humidity in this area is typically high in warm/hot months. The AC system pumps in "fresh" air from outside(if I'm not mistaken), which brings in the humidity, which in turn causes the AC to run more to meet the humidity setpoint on the thermostat. As a result, actual temp is usually colder than the temp set on thermostat. Help me understand... Seems alot of the efficiency is lost due to the ventilation of fresh outside air needed for a spray foamed house.
Side note... Thermostat typically shows a relative humidity 5-10% higher than a seperately purchase hydrometer. I have the RH setpoint at 60% due to this
