Proper Ventilation Is Essential
If you’re building a new house, this can be a real concern. Your architect should be able to design adequate ventilation as part of the plan. But if you have an older house, there are usually enough ways for air to get into your house that tightening up will save you energy but still leave an adequate supply of fresh air. If you are concerned that your house does not have adequate ventilation during certain times of the year, you can get more information about home ventilation at Energy Federation Incorporated (EFI) or the Home Ventilating Institute (HVI). Or, you may download an LBNL report on residential ventilation systems. Simply click on the report title under “Publications.”
