Résumé :

The analysis of life cycle energy (LCE) and life cycle carbon (LCC) of building were performed in this study in order to identify the solutions for reducing energy-related carbon emission throughout building life time. The influence factors associated with building envelop materials (wall, insulation, window, window-to-wall ratio) were evaluated. The result showed that operation phase contributed a vast majority (>90%) of LCE and LCC. Only 4% emissions saving could be achieved if autoclaved aerated concrete block, cellulose insulation and triple glazing were implemented with WWR of 0.17. Th

Buildings are accountable for waste generation, utilization of natural resources, and ecological contamination. The construction sector is one of the biggest consumers of resources available naturally and is responsible for significant CO2 emissions on the planet. The effects of the buildings on the environment are commonly determined using Life Cycle Assessments (LCA).

Energy efficiency has become a crucial part of human life, which has an adverse impact on the social and economic development of any country. In Turkey, it is a critical issue especially in the construction sector due to increase in the dependency on the fuel demands. The energy consumption, which is used during the life cycle of a building, is a huge amount affected by the energy demand for material and building construction, HVAC and lighting systems, maintenance, equipment, and demolition.

Résumé :

The circular economy (CE) is increasingly important in ensuring sustainable development. Although interactions among stakeholders are essential to achieving the CE, existing methods associated with life cycle design do not fully consider the synergies between multiple product life cycles (PLCs). Therefore, this paper proposes a platform-aggregated life cycle ecosystem (PF-LCE). The PF-LCE consists of multiple PLCs along with a platform that enables the exchange of goods and data among different PLCs. We also propose a method for supporting the conceptual design of the PF-LCE. Our method includ

Résumé :

Life cycle assessment (LCA) is used frequently as a decision support tool for evaluating different design choices for products based on their environmental impacts. A life cycle usually comprises several phases of varying timespans. The amount of emissions generated from different life cycle phases of a product could be significantly different from one another. In conventional LCA, the emissions generated from the life cycle phases of a product are aggregated at the inventory analysis stage, which is then used as an input for life cycle impact assessment.

This study applied Life Cycle Assessment (LCA) methodology to investigate the environmental impact of cement production and explore environmental improvements obtained by adding marble waste sludges in the manufacture of Portland cement. It was considered that 6–35% of the limestone required for its production could be supplied by m

As China accelerates its urban development and decarbonization agendas, prefabricated construction has emerged as a promising strategy for delivering low-carbon housing. However, the true carbon performance of prefabricated systems remains understudied, particularly across full building life cycles. This study evaluates the life cycle carbon emissions of a mid-rise prefabricated residential building in Nanjing by integrating Building Information Modeling (BIM) with Life Cycle Assessment (LCA).

Abstract The increasing demand for carrageenan flour products in various industries was directly proportional to the potential environmental impact generated. The environmental impact was global warming (GW) caused by greenhouse gas (GHG) emissions. The industry was one of the producers of GHG emissions from materials, energy, and waste produced. Hence, it hoped that it could improve the eco-friendlier production system. This study aimed to analyze GHG emissions generated in the life cycle of carrageenan flour products and give an alternative strategy for environmental improvement. This resear

In China, urban renewal and renovation projects generate a large amount of demolition waste every year, the disposal of which has certain impacts on the environment. Therefore, more effective policies should be implemented for the management of demolition waste.

Greenhouse gas emissions induced by climate change have garnered global attention. Minimizing climate change can be achieved through the reduction of carbon emissions in transportation infrastructure construction and in the production of construction materials. This study aims to calculate carbon emissions in three hypothetical construction scenarios based on the life cycle assessment (LCA) method when a roadway passes across polluted soil at contaminated sites. Three methods are employed to remediate contaminated soil: off-site cement kiln co-processing, on-site ex-situ thermal desorption, an

The energy mix serves as the basis for calculating the greenhouse gas (GHG) emission factor of electricity, and therefore has a significant impact not only on the evaluation of GHG-related policies but also on the carbon footprint of industries that use electricity in life cycle assessments (LCA). As such, there is a need to annually publish GHG emission factors that reflect changes in the energy mix.
