Description
The End-Use Load and Consumer Assessment Program (ELCAP) conducted for the Bonneville Power Administration by Pacific Northwest Laboratory was initiated to support both conservation assessment and load forecasting missions. This report documents a study of the heat loss characteristics of the ELCAP residential buildings. The basic objectives of this analysis are to: calculate theoretical residential heat loss rate based on the onsite inspection data for use in support of subsequent analyses, determine the distribution of insulation levels and heat loss potential as a function of construction vintage and climate zone, support use of the ELCAP Residential Standards Demonstration Program (RSDP) houses for analysis of the impact of Model Conservation Standards (MCS) by determining the degree to which their construction conforms to the design specifications, and test the specification of current code used in the RSDP experiment. The analysis of the heat loss characteristics of the ELCAP Residential sample leads to several conclusions based on the building-level structural characteristics. These include: the distribution of overall residential heat loss potentials with construction vintage indicates a strong tendency toward lower heat loss potential in newer houses; there is a clear trend toward increasing occupied floor space in newer houses; the data show a steady increase in overall insulation levels in more recently constructed houses; heated basements tend to be concentrated in the two colder climate zones, there is a steady decline in occurrence of crawlspaces and increase in occurrence of heated basements with severity of climate; the distribution of foundation types in the sample does not strongly influence the general trend to higher insulation levels in newer houses and houses in colder climates. 21 refs., 36 figs., 28 tabs.
