Modeled Infiltration Rate Distributions for U.S. Housing



Andrew K. Persily, Amy Musser, Steven J. Emmerich


A set of 209 dwellings that represent 80 % of U.S. housing stock was used to generate frequenc distributions of residential ventilation rates. The set of homes is based on an anal sis of the 1997 U.S. Department of Energ s Residential Energ Consumption Surve , which documents man housing characteristics including t pe, floor area, number of rooms, t pe of heating s stem, foundation t pe and ear of construction. The ventilation rate distributions were developed using the multizone network airflow model, CONTAM (Walton and Dols 2005). In this work, nineteen cities are selected to represent U.S. climatic conditions, and CONTAM simulations are performed for each of the 209 houses in these cities to calculate building air change rates for each hour over a ear. Frequenc distributions are then developed and presented nationall as well as based on house t pe and region.
