Life cycle assessment of roads: Material and process related energy savings
2018
The need for climate change mitigation calls for significant actions to match the sustainable development goals and, in this context, road construction and management play a relevant role (cf. EU Green Public Procurement Criteria for Road Design, Construction and Maintenance and Environmental Product Declarations - EPD). In such a context, the role of the Life Cycle Assessment (LCA) methodology is broadly recognized as a tool to quantify sustainability of processes and systems. This study aims at calculating the life-cycle energy and carbon footprint of a typical Italian urban road, including materials production, transportation, construction, maintenance, and rehabilitation. The LCA approa…
Life Cycle Energy nei Net ZEB: Energia incorporata e consumo di energia in fase di uso
2017
Il concetto di edificio a energia netta zero si sta progressivamente affermando nel panorama scientifico internazionale anche in riferimento ai contenuti delle direttive della comunità europea, secondo cui dal 2020 tutti gli edifici di nuova costruzione in Europa dovranno essere a energia netta quasi zero. Un aspetto chiave della definizione di edificio a energia netta zero riguarda i consumi di energia relativi alla fase di uso: un edificio deve riuscire a garantire una generazione di energia in sito pari ai consumi della fase di uso. L’approccio generalmente condiviso dalla maggior parte degli studi di letteratura è quello di considerare solamente l’energia della fase di uso, a causa dell…
Environmental profile of building materials. Field analysis of a brickwork in Sicily
2005
Brickmaking process is a highly energy-intensive operation, where a considerable amount of energy is spent in the drying and firing processes of bricks. Moreover, most of the Sicilian brick industries utilise electricity, fuel oil and gas oil. On the other hand, the conservation of energy becomes important in the aim of limiting greenhouse gas emission into the atmosphere and reducing costs of materials. In this work, an experimental analysis of the energy utilised in a Sicilian brickwork for the realization of some typical bricks has been carried out. From this study, the embodied energy of the unity of product has been deduced. Finally, by means of an indirect method, the pollutants relea…
