Calculating Hohokam Domestic Architecture Building Costs to Test an Environmental Model of Architectural Changes

Studies of domestic architectural variation are rare in archaeological research, possibly because the essential methods remain underdeveloped. To encourage a comparative approach to explaining the construction differences in household dwellings, we designed and utilized objective and easily applied means to calculate labor costs for constructing a variety of domestic architectural styles in Hohokam society. We applied Abrams's (1989, 1994) approach, labelled architectural energetics, which converts architecture into its labor equivalents for building structures. By doing so, we derived standard units of measurement that promote comparative analysis. To demonstrate the method's utility, we turned to the pithouses and adobe surface structures at Pueblo Grande. We wanted to test whether the history of construction was driven by environmental degradation, and, in particular, a depletion over time of wood resources for home building (see Loendorf and Lewis 2017). Our analysis indicated that factors in addition to wood depletion likely contributed to the architectural changes at Pueblo Grande and across the Hohokam world.
