Abstract

Air leakage and other diagnostic measurements are being added to LBNL's Residential Diagnostics Database (ResDB). We describe the sources of data that amount to more than 80,000 blower door measurements. We present summary statistics of selected parameters, such as floor area and year built. We compare the house characteristics of new additions to ResDB with prior data. Distributions of normalized leakage are computed for income-qualified homes that were weatherized, homes that were participants of various residential energy efficiency programs, and new constructions built between 2006 and 2011. Further work is underway to relate air leakage to house characteristics utilizing the full database for predictive modeling of air infiltration and to support studies of energy efficiency. Current status of ResDB can be found at http://resdb.lbl.gov/.
