Re: I'm looking for idea's to make my home energy efficient

I am not an expert in this area, but I do know that if you seal your house so tightly that the air exchange rate is inadequate, moisture and air quality issues can arise (see http://www.epa.gov/iaq/homes/hip-ventilation.html). If you are planning on turning your home into a super high insulated house, you may want to ask a licensed HVAC contractor about options for ensuring that ventilation will be adequate. There is a device called an air-to-air exchanger (also sometimes called a heat recovery ventilator) that can be installed to increase the airflow in your home and remove indoor moisture and pollutants. It requires maintenance and has its advantages and disadvantages. Other ventilation options and moisture control techniques also exist (see, e.g., http://www.epa.gov/iaq/homes/hip-moisture.html). If you have concerns about this issue, I strongly suggest that you contact a professional for assistance.
