This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www.nrel.gov/publications. Residential Climate Area 4: Hot-Dry/Mixed-DryThe Hot-Dry/Mixed-Dry climate region covers southern California, the California Central Valley, southern Nevada, southern Arizona, southern New Mexico, and west Texas. Homes in this area represent 12% of U.S. housing units and residential buildings, and 6% of the residential thermal end-use energy. Figure 14 shows the 33 segments in the Hot-Dry/Mixed-Dry region, with the number of buildings, average building size, average thermal end-use intensity, and annual thermal end-use energy used in each segment.

Modeled Results of Four Residential Energy Efficiency Measure Packages for Deriving Advanced Building Construction Research Targets

“…This step involved organizing the results by typology segments (as defined in Reyna et al [5]) to gain insights into the variation by climate zone, building type, vintage, and other parameters. We then visualized and interpreted the results in different ways.…”

An eight-step simulation-based framework to help cities reach building-related emissions reduction goals

“…1980 in particular reflects the post-oil crisis implementation of building energy codes across the U.S. that led to standard energy-efficient construction practices. Each building in the city was assigned non-geometric properties along the divisions of these archetypes using the DOE's age-appropriate residential building data and some tacit knowledge of the building stock with salient characteristics documented in table 2 [47,48]. In this study, due to the lack of additional data, all on-site combustion of fossil fuels is assumed to be natural gas.…”
