SUP R DSS: A sustainability-based decision support & system for road pavements
2019
Road pavement community members are increasingly becoming aware of the need to incorporating the principles of sustainable development into the sector. Policies are also going in this direction and as a consequence in the recent years researchers and practitioners are coming up with new materials, technologies and practices designed to reduce the negative impacts of their activities in the surroundings. Within this framework the road pavements sector is witnessing a paradigm shift towards the development of pavement technologies incorporating high-content of recycled materials, as well as best practices to decrease the overall carbon footprint. These are all promising solutions that to the …
Design of the seismic retrofit of a school in accordance to a life cycle thinking approach
2018
The public consciousness of the seismic risk is continuously increasing, although the damage on existing and older buildings due to earthquakes is still high, due to a former structural design not accounting for the latest knowledge achieved in the seismic field. This is particularly true considering the damage recorded in the last earthquakes that hit Central Italy in August and October 2016. The paper deals with the repair actions required in the elementary school of Pievebovigliana (Macerata-Italy) after the aforementioned seismic events. The school is a one-story building characterized by an irregular plan layout; masonry walls with regular blocks are the main supporting structure. An a…
Approccio “Life Cycle Thinking” applicato alla riparazione di una scuola danneggiata dal terremoto dell’Italia centrale
2017
L’adeguamento sismico ed il miglioramento energetico delle strutture sono diventati al giorno d’oggi una priorità. Buona parte del patrimonio edilizio esistente si trova in stato di grande obsolescenza strutturale, architettonica ed energetica. Oltre alla prevenzione, tuttavia, un aspetto molto importante riguarda la riparazione e riqualificazione degli edifici resi inagibili dagli eventi sismici recentemente accaduti nel territorio nazionale. In modo particolare, nel presente articolo verrà preso in considerazione un edificio del plesso scolastico sito nel Comune di Pievebovigliana, provincia di Macerata, danneggiato dai terremoti che hanno colpito l’Italia centrale il 24.08.2016 e il 30.1…
A Constructal Law optimization of a boiler inspired by Life Cycle thinking
2018
Abstract The aim of the paper is to explore how design optimization contributes to a technology's ecological evolution. The article develops this concept through an application of Constructal Law, used to account for the “evolution” of technologies design (configuration, shape, structure, pattern, rhythm), and Life Cycle Assessment (LCA), used for quantifying the environmental impacts of the design choices. The combination of both methods assesses how technology evolution affects the environment during its life, extending the concept of evolution of design. The study is applied to a case study of a real biomass boiler. The study analyses basic case and a series of alternative scenarios opti…
Life-Cycle Land-Use Requirement for PV in Vietnam
2021
Over the last 15 years, photovoltaics (PV) in Vietnam has experienced development. The increased installed capacity of PV requires more land for installation sites as well as for manufacturing the plants’ component and waste treatment during the plants’ decommissioning. As a developing country, in which more than 80% of the population’s livelihood depends on agriculture, there are concerns about the competition of land for agriculture and solar development. This paper estimates the life-cycle land-use requirement for PV development in Vietnam, to provide the scientific-based evidence for policy makers on the quantity of land required, so that the land budget can be suitably allocated. The d…
