High Performance Homes in the Southwest

Savings Potential, Cost Effectiveness and Policy Options

This 2007 report evaluates the energy and cost savings potential from constructing more efficient new homes in five Southwest states, and makes policy recommendations to achieve greater energy savings in new homes. This report analyzes the energy savings and net economic benefits of three tiers of home performance: ENERGY STAR (20-30% savings), Best Practice Homes (30-50% savings) and Net Zero-Energy Homes (50-60% savings) using the Building Energy Optimization model (BEopt) developed by the National Renewable Energy Laboratory (NREL). The report makes policy recommendations to achieve greater energy savings in new homes through programs and incentives offered by utilities, states and local governments.

The following are links to the executive summary of the study, the complete study, a fact sheet, and SWEEP's press release.
