Initial Results

The demand for high performance “green” or “sustainable” buildings is rapidly becoming the most significant trend in the building industry. As the Architecture, Engineering, and Construction (AEC) industry develops the strategies and technologies for these projects, an increased emphasis must be placed on the processes and competencies required to deliver high performance buildings. This paper defines an emerging research and education program at Penn State called the Lean and Green Initiative. Focused on understanding all aspects of the delivery of high performance projects, this program is underpinned by established process-based theories and structured around a systematic methodology designed to minimize waste, maximize value, and reduce cost. Current research and educational activities are described in the paper including nine primary research thrusts and their respective goals. Initial results of each research thrust are also provided, providing an early look at the benefits of a process improvement approach to the delivery of high performance buildings.

High Performance Buildings

The purpose of this study was to provide a guideline for the selection of technologies suitable for ASHRAE international climate zones when designing high-performance buildings. In this study, high-performance technologies were grouped as passive, active, and renewable energy systems. Energy saving technologies comprising 15 cases were categorized into passive, active, and renewable energy systems. EnergyPlus v9.5.0 was used to analyze the contribution of each technology in reducing the primary energy consumption. The energy consumption of each system was analyzed in different climates (Incheon, New Delhi, Minneapolis, Berlin), and the detailed contributions to saving energy were evaluated. Even when the same technology is applied, the energy saving rate differs according to the climatic characteristics. Shading systems are passive systems that are more effective in hot regions. In addition, the variable air volume (VAV) system, combined VAV–energy recovery ventilation (ERV), and combined VAV–underfloor air distribution (UFAD) are active systems that can convert hot and humid outdoor temperatures to create comfortable indoor environments. In cold and cool regions, passive systems that prevent heat loss, such as high-R insulation walls and windows, are effective. Active systems that utilize outdoor air or ventilation include the combined VAV-economizer, the active chilled beam with dedicated outdoor air system (DOAS), and the combined VAV-ERV. For renewable energy systems, the ground source heat pump (GSHP) is more effective. Selecting energy saving technologies that are suitable for the surrounding environment, and selecting design strategies that are appropriate for a given climate, are very important for the design of high-performance buildings globally.

For several years, National Park Service scientists, historians, and educators have been working with National Science Foundation-funded High Performance Wireless Research and Education Network (HPWREN) researchers on developing, implementing, and evaluating Live Interactive Virtual Explorations (LIVE) at several sites. The LIVE activities utilize computers with headsets and microphones to link National Park Service sites with an array of audiences. The two case studies in this paper examine the effectiveness of LIVE activities that allow Washington, DC, inner-city youth to explore two hard-to-reach National Park Service sites: Knife River Indian Villages National Historic Site in North Dakota and the Hawaii Volcanoes National Park.

Initial Results

Heat pipes have been gaining a lot of popularity in electronics cooling applications due to their ease of operation, reliability, and high effective thermal conductivity. An important component of a heat pipe is the wick structure, which transports the condensate from condenser to evaporator. The design of wick structures is complicated by competing requirements to create high capillary driving forces and maintain high permeability. While generating large pore sizes will help achieve high permeability, it will significantly reduce the wick’s capillary performance. This study presents a novel experimental method to simultaneously measure capillary and permeability characteristics of the wick structures using fluorescent visualization. This technique will be used to study the effects of pore size and gravitational force on the flow-related properties of the wick structures. Initial results are presented on wick samples visually characterized from zero to nine g acceleration on a centrifuge. These results will provide a tool to understand the physics involved in transport through porous structures and help in the design of high performance heat pipes.

For the past decade, researchers affiliated with the National Science Foundation-funded High Performance Wireless Research and Education Network (HPWREN) have been working with Native American education communities on an array of Internet-enabled activities, including the Live Interactive Virtual Explorations (LIVE) pilot project. One of the communities involved with the pilot LIVE project is the Pala Native American Learning Center, which is located in rural San Diego County, California. This paper discusses five case studies encompassing LIVE activities between Pala tribal community members and field scientists/educators throughout southern California. Using laptops equipped with off-the-shelf accessories and freeware, the five pilot case studies demonstrate the advantages and disadvantages of utilizing the LIVE concept for real-time distance education programs at rural Native American communities.
