This report analyzes savings in the multifamily sector attributable to the MCS code. Multifamily buildings constructed in different years in Tacoma comprise our MCS and control samples. For the multifamily sector in weather zone 1, in which Tacoma is located, the NPPC estimated that apartment units in buildings built to MCS would consume 1.2 kWh/ft/sup 2//year for space heating electricity versus the estimated 3.4 kWh/ft/sup 2//year consumed by units in buildings built to current practice. The NPPC estimated that the MCS code would cut space heating requirements by 65% per square foot per unit in the multifamily sector. This estimate greatly exceeds savings to date attributable to conventional weatherization programs in this sector. This document reports that MCS savings of approximately 15% to 25%, which fall in between the NPPC estimates for construction of energy efficient new buildings and those of other programs. This paper discusses the data and general research methodologies used in this work. The buildings, units and occupants are profiled, and space heating savings estimates based on models of individual units and buildings are presented. A great deal of attention is directed to handling modeling problems caused by changing occupancy and vacancies in the sample buildings. 31 refs., 3 figs., 22 tabs.
