This research examined the environmental impacts due to the construction phase of commercial buildings. Previous building research has often overlooked the construction phase and focused on the material and use phases, discounting the significant environmental impacts of construction. The research was conducted using life-cycle assessment ͑LCA͒ methodology,(More)
This study analyzed the environmental impacts of the materials phase of a net-zero energy building. The Center for Sustainable Landscapes (CSL) is a three-story, 24,350 square foot educational, research, and administrative office in Pittsburgh, PA, USA. This net-zero energy building is designed to meet Living Building Challenge criteria. The largest(More)
The term <i>green</i> computing has become effectively synonymous with low-power/energy computing. However, for computing to be truly sustainable, all phases of the system life-cycle must be considered. In contrast to the considerable effort that has been applied to address the use-phase energy consumption issue---ranging from battery powered embedded(More)
The embedded class processors found in commodity palmtop computers continue to become increasingly capable while retaining an energy-efficient footprint. Palmtop computers themselves, including smartphones and tablets, provide a small form factor system integrating wireless communication and non-volatile storage with these energy-efficient processors. In(More)
Green computing has become synonymous with low-power/energy computing. However, many environmental impacts of computing, such as manufacturing, are significant, possibly moreso than the operational/use phase. In this paper we motivate manufacturing as an issue of sustainable computing. We also demonstrate the manufacturing component of chips plays a(More)

The historic reliance on fossil fuels as a primary energy source has made combating climate change one of the leading environmental challenges facing society today. Buildings account for 72%, 39%, 38%, and 14% of electricity consumption, energy use, carbon dioxide emissions, and water consumption, respectively [1-2]. Twelve cities have joined the(More)

Brazil's status as a rapidly developing country is visible in its need for more energy, including electricity. While the current electricity generation mix is primarily hydropower based, high-quality dam sites are diminishing and diversification to other sources is likely. We combined life-cycle data for electricity production with scenarios developed using(More)
