Description of the Building Materials Data Base for Pittsburgh, Pennsylvania

摘要

A building materials sampling program for the Pittsburgh, Pennsylvania, region was conducted in December 1984 through February 19, 1985 to examine the types and amounts of building surface materials exposed to acid deposition. A stratified, systematic, unaligned random sampling approach was used to generate sample points across six sampling frame areas. A minimum of 70 sample points was examined per sampling frame to yield a total sample size of 541 points. Building sizes, surface materials, roof characteristics, roof-mounted apparatus, chimneys, gutters, downspouts and fences were recorded. This report provides an initial summary of the data collected. Keywords: Statistical analysis; Acid precipitation; Damage assessment; Damage from acid deposition; Damage to buildings. (Author)
