An Assessment Of Building Energy Efficiency Options At Horn Island Ranger Station, Gulf Islands National Seashore, Florida Solar Energy Center, Stephen Barkaszi Dec 1999

An Assessment Of Building Energy Efficiency Options At Horn Island Ranger Station, Gulf Islands National Seashore, Florida Solar Energy Center, Stephen Barkaszi

FSEC Energy Research Center®

As requested by Joe Martin of the National Park Service (NPS), Southeast Support Office, researchers from the Florida Solar Energy Center (FSEC) conducted a building energy efficiency assessment for the ranger station on Horn Island, Mississippi. The assessment included audits and inspections of the energy systems, building thermal performance, appliances, and energy use patterns. FSEC researchers Stephen Barkaszi and John Harrison conducted the audits and on-site inspections June 29 and June 30, 1999. The purpose of the assessment was to evaluate the facility and to present recommendations for improving the energy efficiency of the building. This report summarizes the information …

Environmental Performance Analysis Of Solid Freedom Fabrication Processes, Yanchun Luo, Zhiming Ji, Ming-Chuan Leu, R. J. Caudill

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This paper presents a method for analyzing the environmental performance of solid freeform fabrication (SFF) processes. In this method, each process is divided into life phases. Environmental effects of every process phase are then analyzed and evaluated based on the environmental and resource management data. These effects are combined to obtain the environmental performance of the process. The analysis of the environmental performance of SFF processes considers the characteristics of SFF technology, includes material, energy consumption, processes wastes, and disposal. Case studies for three typical SFF processes: stereolithography (SL); selective laser sintering (SLS); and fused deposition modeling (FDM) are presented …
