Humidity control is necessary in any well insulated house located in a humid climate. We learned this when we built our house in 2002. When the outside temperature rose into the 80's or 90's and the dew point into the 70's, the inside temperature would stay in the low 70's and the inside turned into a swamp. We had a choice - get a dehumidifier or turn on the heat. We got the dehumidifier.

Above grade or below makes no difference - it's the indoor relative humidity. Mold happens when indoor relative humidity gets over 60%.
