Data Quality Requirements for Determining Energy Savings in the Weatherization Assistance Program (WAP)
Abstract
This paper briefly describes an ongoing
energy retrofit program, the Weatherization
Assistance Program (WAF') of the Texas
Department of Housing and Community Affairs.
After briefly reviewing the various parameters
that one needs to consider for proper baseline
model development, this paper illustrates the
differences in energy savings one would obtain
by direct utility bill comparison as against
weather normalizing. Next, PRISM (PRInceton
Scorekeeping Method), a widely used
methodology and software for determining
retrofit savings, is presented and discussed. The
importance of assuring proper data quality is
highlighted and its adverse effects on the
baseline model is illustrated with data from two
College Station homes.
Finally, this paper presents preliminary
problems encountered while preparing input
data for PRISM runs for 462 houses in 59 Texas
cities under WAP. Common problems in the
utility bills and temperature data from National
Oceanic Atmospheric Agency (NOAA) are
discussed and recommendations to avoid such
data quality problems are made.
