Metodología para la evaluación de la sostenibilidad en autopistas: Cálculo del balance energético de la infraestructura

Abstract

The work tackles the development of a procedure to evaluate the energetic efficiency in linear infrastructures from a constructive point of view. This procedure allows to calculate the balance of energy along the different phases of life cycle analysis in infrastructure, such as construction, operation - maintenance and deconstruction, both in general and independent terms. Being the target the quantification of energy in the infrastructure, the procedure allows the efficient management of its energy consumption and other environmental impacts, throughout the selection of alternatives and the mitigation or compensation of the balance between its different phases. This paper describes the developed methodology in the procedure, tested by means of a practical example case study, where the embodied energy of one of the functional units in which the motorway is divided a straight two-way highway stretch is quantified in Jules. The individual amount of different phases is also quantified to establish a balance between them too.
