Exergy as a driver for achieving sustainability

 · Achieving sustainability presents many challenges, in many fields. Of those, the energy sector is probably one of the most relevant: its large economic, social, environmental or technological implications, as well as the long time periods associated with it, require a careful look at the ways in which to assess the sustainability of this sector Cited by: Exergy-based Index for the assessment of building sustainability. Ahmed El shenawy, Ph.D. Concordia University, The declining state of the environment, combined with the increasing scarcity of natural resources and economic recession, presents us with the need to discover building practices that are capable of producing sustainable buildings. Building promoters are Cited by: 1. Abstract Exergy analysis is shown to be an important tool for achieving sustainable development. By noting that energy can never be “lost,” as it is conserved according to the first law of thermodynamics, while exergy can be lost due to internal irreversibilities, the study suggests that exergy losses, particularly due to the use of nonrenewable energy forms, .

Abstract Exergy analysis is shown to be an important tool for achieving sustainable development. By noting that energy can never be “lost,” as it is conserved according to the first law of thermodynamics, while exergy can be lost due to internal irreversibilities, the study suggests that exergy losses, particularly due to the use of nonrenewable energy forms, should be minimized to attain. ABSTRACT Exergy-based Index for the assessment of building sustainability Ahmed El shenawy, Ph.D. Concordia University, The declining state of the environment, combined with the increasing scarcity of natural resources and economic recession, presents us with the need to discover building practices that are capable of producing sustainable buildings. The relevance of exergy to the life cycle assessment (LCA) of buildings has been studied regarding its potential to solve certain challenges in LCA, such as the characterization and valuation, accuracy of resource use, and interpretation and comparison of results. However, this potential has not been properly investigated using case studies. This study develops an exergy-based LCA method and.

After the system and surroundings reach equilibrium, the exergy is zero. Determining exergy was also the first goal of thermodynamics. The term "exergy" was. Several case studies highlight the insights revealed using exergy and exergetic aspects of sustainability. It is concluded that the potential usefulness of. Achieving the sustainable development objective called clean water and sanitation is possible if exergy studies are approached, and the positive impact of.
