Thermal Performance of the Hood River End-Use Metered Homes.

摘要

The Hood River Conservation Project (HRCP) sponsored by the Bonneville Power Administration (Bonneville) involved the entire community of Hood River, Oregon, in one of the largest weatherization experiments ever conducted. Two goals were set in the experiment: to weatherize all homes to a predetermined cost-effectiveness limit and to gather the necessary data to assess the success of the retrofitting in terms of saved kWh/yr. The results reported here were commissioned by Bonneville as part of the effort to determine the thermal performance characteristics based on high time-resolution data. Results were then compared to results obtained from another methodology that uses billing data. As part of the HRCP data collection, approximately 300 homes were enduse metered. These homes were predominately single-family homes but did include several multifamily units and about 50 manufactured homes. The enduse data, along with some survey data, form the data set for the thermal characterizations summarized in this report. In the thermal analysis described here, the metered data is used to characterize the heating load as a function of inside-outside temperature difference. An annualized estimated consumption (AEC) for electrical space heat for the home is estimated under a set of standard conditions. This quantity is ideally suited for pre- and post-retrofit comparisons as it is weather-normalized, adjusts for any changes in inside air temperature on a daily basis, and is not affected by intermittent wood use. Additional thermal parameters are derived from a robust linear fit of space heat to inside-outside temperature difference. Changes in inside operating temperatures and wood-stove usage patterns are also investigated.
