Download or read book As operated Heat Loss Coefficients of Residential Buildings in the Pacific Northwest written by and published by . This book was released on 1992 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous research of residential electrical space-heating data has revealed that the heat loss coefficients obtained from empirical data (''as-operated'' UAs) are, on average, about 25% below the UA calculated from the shell construction of each building. This as-operated UA is obtained from a linear regression of the measured space-heating energy consumption versus the inside-outside temperature difference. This finding indicates that simple steady-state calculation techniques for heating energy consumption utilizing only UAs may be inaccurate in estimating annual consumption. The purpose of this research was to study how climate, construction, and occupant variables may affect the as-operated UA and, therefore, the annual heating energy consumption. Specifically, the goal is to gain a greater understanding of how and why the as-operated UA differs from the construction-based nameplate UA. Multiple seasons of daily heating data from 131 occupied single-family residential sues were analyzed. A multiple linear regression was used to generate a model that utilizes the construction-based UAs and other characteristics of individual residences to predict an as-operated UA that better estimates annual heating energy.

This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An electric coheating experiment was conducted on a double-envelope house in Arvada, Colorado, to determine the total heat loss coefficient (UA) of the double-shelled structure, as well as the heat loss coefficients of the inner and outer shells. Electric coheating is fairly well established as an experimental method for determining the total heat loss coefficient in conventional residential buildings. However, special problems are introduced with passive and double-envelope buildings. A new methodology was developed to meet these problems. That methodology and the results of the experimental investigation are presented and discussed.

Book excerpt: 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.
