Measured space-cooling electricity savings from standard energy conservation measures, radiant barriers, and high-efficiency window air conditioners.

摘要

A cooperative field test was performed in Tulsa, Oklahoma, to determine the space-cooling electricity consumption of low-income homes equipped with window air conditioners, the reduction in consumption due to energy conservation measures (ECMs) installed under Oklahoma's Weatherization Assistance Program (WAP), and the additional reduction due to two ECMs designed to reduce space-cooling electricity consumption: attic radiant barriers and replacement of low-efficiency window air conditioners with high efficiency units. Eighty-one single-family, owner-occupied houses were divided into a control group and three treatment groups: ECMs performed under Oklahoma's WAP, WAP ECMs plus a truss-mounted attic radiant barrier, and WAP ECMs plus a high-efficiency window air-conditioner to replace a less efficient unit. Pre-weatherization data were collected during the summer of 1988 and post-weatherization data were collected the following summer. Air-conditioning electricity consumptions and indoor temperatures were monitored weekly. Air-conditioning energy use models and regression analyses were employed to normalize annual space-cooling electricity consumptions and savings to average outdoor temperatures and pre-weatherization indoor temperatures. 5 refs., 4 figs., 1 tab.
