There are more than 8 million private swimming pools in the U.S.. Though known to be prodigious consumers of water and energy, apparently there has been no systematic analysis of their environmental impact to date. Additional impacts arise from pool chemical use and pool construction. Phoenix, Arizona, has one of the highest concentrations of pools in the country. This is despite large evaporative...
The looming challenges of global warming and peak oil have begun to spur the development of alternatives to our current petroleum based transportation system. However, before these alternatives are implemented on a significant scale, it is important to assess these technologies with a broad lens and ensure that they will not introduce more problems than they will solve. In this study, a life cycle...
The demand for data center solutions with lower total cost of ownership and lower complexity of management is driving the creation of next generation datacenters. The information technology industry is in the midst of a transformation to lower the cost of operation through consolidation and better utilization of critical data center resources. Successful consolidation necessitates increasing utilization...
The Millenium Ecosystem Assessment (MEA) has highlighted the fast depletion of ecosystem services over the past 50 years and has identified their crucial role in human well-being. This emphasizes the need of accounting for ecosystem goods and services in life cycle of products and processes. Despite the availability of numerous Life Cycle Assessment (LCA) techniques, most methods only account for...
In this paper we address the problem of taking the general notion of sustainability as reported in the Brundtland Report and later in Arrow et al approach and interpreting it from a thermodynamics point of view, with a goal of developing operational principles of sustainability in terms of physical principles that complement economic views.
In this paper, we describe an integrated design and management approach to creating a sustainable IT ecosystem: a physical infrastructure where information technology has been seamlessly interwoven to improve environmental efficiency while achieving lower cost. Specifically, we describe five principles to achieve such integration: ecosystem-scale life-cycle design; scalable and configurable resource...
