How State Interventions Affect Municipalities Taking The Lead In Sustainability, Jayce L. Farmer, Andres J.Rodriguez Lombeida

Public Policy and Leadership Faculty Research

The state and local governments throughout the United States interact within a complex system of multilevel governance to advance sustainability. However, we know little about what this hierarchical system of exchanges means for municipalities as they work to achieve energy efficient government operations. Drawing on a perspective of “contested federalism”, we examine how the transaction costs of state–local government relations affect the efforts of U.S. cities to lead by example and promote sustainability within their internal processes. We apply a Bayesian item response theory approach to assess the effects of state-level fiscal and policy interventions on municipal commitments to energy …

Design Guidelines And Strategies For Thermal Solar Management Of Fenestration In The Desert Climate, David Mccredo

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research evaluates the effects of varying thermal properties of windows in

residential energy use for the moderate altitude and 36'N latitude climate of southern

Nevada, which has a distinct cooling season. A selection of windows across different

shading conditions and total window areas were studied using BEopt energy simulation.

Findings demonstrate that for the specific climate, latitude, and altitude of Las Vegas,

Nevada, the most expensive “high performance” windows are not always the best

option in terms of total site energy use, and can be outperformed by properly shaded

less advanced windows. Under certain conditions, shading was found to …
