Integration of Building into Nature for the Valles Caldera National Preserve Visitor Center

Valles Caldera National Preserve, located in northern New Mexico, has an opportunity to implement sustainable design concepts while demonstrating long-term financial sustainability in the design of its new visitor center. This building can be designed to use natural systems to provide energy and water, and to blend in with the setting‰Ûªs unique historical and natural landscape. Structures can be integrated into nature by incorporating common techniques, features, and materials of a particular period, area, or people. This analysis identified capital costs for both traditional and sustainable construction techniques, as well as long-term operational costs. The results demonstrate that capital costs of sustainable design that is integrated into the landscape can be comparable to conventional costs and provide long-term operational costs savings.

Integration of Sustainable Development Principles into a Community Park

Characteristics of six operating hot spring recreational facilities were reviewed to identify opportunities for integrating a range of sustainable design and operation approaches into a community park. Potential operating cost savings were evaluated for a conceptual landscape project, bathhouse project, and swimming pool project that reduced the use of electricity, natural gas, water, the discharge of water, and solid waste generation. The projects showed a combined cost savings of approximately $40,000 per year by adopting passive solar design, energy efficient lighting, native vegetation, water efficient fixtures, and a natural swimming pool. The greatest potential operating cost reductions were observed for cutbacks in the use of swimming pool water and reductions in natural gas needed for building and swimming pool heating.

An Analysis of U.S. Air Force Policy and Installation CO2 Emissions to Determine Best Practices for the Implementation of Executive Order 13514

United States Air Force (USAF) energy policy is a measured but aggressive response to federal energy policy guidance. Previous USAF efforts, like those of the federal government, focused primarily on energy intensity reduction, cost, and BTU savings, and in certain cases have resulted in facility greenhouse gas (GHG) emission reductions. The USAF now faces the challenge of integrating GHG reduction goals and inventory requirements set forth in Executive Order 13514. Using USAF reported energy consumption data, facility GHG emission estimates have been synthesized to identify trends and elucidate existing energy best practices to be applied as part of overarching USAF GHG mitigation efforts and to highlight areas of possible concern for the integration of EO 13514 into operational USAF policy.
