| dc.title | Life cycle carbon emissions for zero emission building and renewable energy systems | en_US |
| dcterms.abstract | Construction industry is an industry that consumes a lot of resources and causes a large burden on environment. Based on the study, construction activities use 40% of the total natural resources, and the construction waste also occupies for 40% of the total waste made by human. Therefore, the low-carbon emission reduction of the construction area is imminent. Correspondingly, this also means that the potential of energy saving, also the potential of carbon emission reduction in the construction area is huge. | en_US |
| dcterms.abstract | This dissertation firstly analyzes the current situation of international building development and its carbon emissions; secondly, starting from the building life cycle, it is discussed in three stages. For the material stage, both the embodied carbon of building materials and renewable energy system materials are taken into account, and the changes in energy consumption caused by the replacement of building materials are studied. For the operation and maintenance phase, the solar PV system and wind turbine system are applied to meet the building energy demand, Trnsys software is used for real-time simulation, and the energy carbon emission factor method is applied to calculate the impact of this phase on carbon emissions. For the on-site construction and disposal stages with a small proportion, the estimation is carried out through basic parameters such as building floor and area. In addition, from both economic and technical aspects, the system is objectively evaluated by using multiple evaluation indicators. | en_US |
| dcterms.abstract | In this study, an active strategy and a passive strategy are used in parallel. On the passive strategy, more energy-efficient materials are selected; in the active strategy, a renewable energy system is used. Clarify the carbon emission measurement process and data at each stage, and finally achieve the goal of zero carbon emission throughout the whole life cycle of the building. This paper clarifies the calculation process of carbon emissions in the whole life cycle of buildings, and builds an evaluation model for carbon emissions in the whole life cycle of buildings, which provides assistance for further research on global building carbon emissions. | en_US |
