So in order to be more energy efficient last year we re-insulated the entire house inside and out, dug down 6 feet and insulated the outside of the basement, installed all brand new low-e argon gas windows and just had our heating ducts re-done. It has officially bitten us in the rear.
The house is now too sealed for moisture to escape so we have to run a de-humidifier night and day (doesn't help conserve energy even though it is an efficient model) we also cannot have the heat lower than 70 degrees at all times (when before we would have it at 68-69 degrees during the day and 65-67 while sleeping or away). If we do not do these things our humidity level can get up to 70% which is VERY unhealthy! Also our windows collect the moisture and cause mold. Even doing these things we still have 50% humidity which is still relatively high. We talked to the window guy and he said he sees this all the time now, houses are too energy efficient and it is causing high levels of indoor air pollution as well as moisture issues like mold or bacteria.
Anyone else experienced this? Have any suggestions or know of a solution?
