Title: Attic ventilation and air sealing: A technical review of the issues. Final report

This report was commissioned by the New York State Energy Research and Development Authority and the New York State Department of State to review the history and state-of-the-art of attic ventilation and air sealing. It includes a mathematical model that is used to examine the complex relationships between such variables as attic bypass leakage area, outside air temperature, household moisture production, and venting area. The primary recommendation is to reduce heat and moisture flows into the attic by permanently sealing all air leakage paths between the house and attic, especially in climate areas that experience sustained periods of low wintertime temperatures. It concludes that current attic ventilation codes, which omit reference to considerations of climate zones, are of marginal utility to the building or retrofit industry and are in need of revision. Recommendations for further research are included.
