Abstract

The ever-growing demand for electricity and rapidly increasing power rates in the Desert Southwestern part of US have greatly impacted the base needs for heating and cooling of homes, especially among those who require lowcost or public housing. Integration of design concepts like daylighting and passive/active solar energy, result in a considerable saving of building and operation costs of public housing in the valley. Incorporating these concepts low-cost and public housing can be made energy efficient and sustainable, eventually making it a zero-energy home. A zero-energy home (ZEH) combines state-of-the-art, energy-efficient construction and appliances with commercially available renewable energy systems such as solar electricity and solar water heater. This combination can result in net zero energy consumption. A ZEH, like most houses, is connected to the utility grid, but can be designed and constructed to produce as much energy as it consumes on an annual basis. With its reduced energy needs and renewable energy systems, a ZEH can, over the course of a year give back as much energy to the utility as it takes. In this paper, a public housing development is considered. With the appropriate selection of design criteria, including building skin insulation, orientation, axis, treatment of windows/openings and shading devices, cooling and heating loads can be eliminated or reduced considerably during Summer and Winter respectively. The computer analysis package E- Quest is used to determine minimum life cycle costs of the buildings considered. Solar power generation via roof-mounted PV panels is considered in the design, but the houses are assumed to be initially configured without the actual addition of this particular option. It will be able to be added later when funding availability and costs may come closer into balance. The main purpose of this paper is to arrive at the most appropriate design solution to maximize cost savings and minimize energy load in low-cost public housing in the Southwest portion of the US. Design weather data from Nevada will be used for this particular study. Nevada being one of the most highly suitable states for the generation of solar power in the United States should be utilized to the maximum extent possible.
