life cycle recurrent Embodied Energy calculation of buildings a review
Journal of Cleaner Production, 2019Co-Authors: Manish K. DixitAbstract:Abstract Buildings use approximately 48% of global Energy each year in their construction and operation as Embodied and operating Energy. The Embodied Energy is used directly through onsite and offsite construction and related processes, and indirectly through the use of materials and equipment. The Embodied Energy used in a building's construction is called initial Embodied Energy (IEE), whereas the Energy Embodied in the recurring processes of maintenance, repair, and replacement is termed recurrent Embodied Energy (REE). To effectively optimize a building's life cycle Embodied Energy, both the REE and IEE must be evaluated collectively. However, a building's REE depends on multiple parameters, which can cause significant variations of REE results across studies. A thorough investigation of parameters specific to REE calculation is currently lacking. The REE parameters may introduce significant uncertainties in the life cycle Embodied Energy calculations. In this paper, we perform a systematic review of literature to identify key parameters affecting REE calculations. We also propose a framework to identify and quantify the uncertainties resulting from these parameters. The findings of this study will help streamline the process of life cycle Embodied Energy calculation.

life cycle Embodied Energy analysis of residential buildings a review of literature to investigate Embodied Energy parameters
Renewable & Sustainable Energy Reviews, 2017Co-Authors: Manish K. DixitAbstract:Approximately half of the annual global Energy supply is consumed in constructing, operating, and maintaining buildings. Because most of this Energy comes from fossil fuels, it also contributes greatly to annual carbon emissions. When constructing a building, Embodied Energy is consumed through construction materials, building products, and construction processes along with any transportation, administration, and management involved. Operating Energy is used in space conditioning, heating, lighting, and powering building appliances. In order to effectively reduce the carbon footprint of buildings, a comprehensive reduction in both Embodied and operating Energy is needed. Studies so far have focused on reducing either Embodied or operating Energy in isolation without realizing the trade-off that exists between them. Also, building Energy research has concentrated more on operating Energy than Embodied Energy, and as a result, the operating Energy of buildings is gradually decreasing. Due to a variety of issues, however, few efforts have been undertaken to comprehensively minimize Embodied Energy.

Embodied Energy and cost of building materials: correlation analysis
Building Research and Information, 2016Co-Authors: Manish K. DixitAbstract:ABSTRACTThe US building sector consumes 48% of the nation’s annual Energy as operating and Embodied Energy. Calculating Embodied Energy is difficult, complex and more resource-consuming than calculating operating Energy due to a lack of complete, accurate and specific Embodied Energy data. One commonly used method to calculate Embodied Energy is input–output-based (IO) analysis, which utilizes economic data. The use of economic data indicates some relationship between Embodied Energy and cost. Some studies have investigated whether the Embodied Energy of a building can be predicted from its cost. These studies analyzed the relationship of the cost and Embodied Energy of a building and found a strong, positive correlation. However, when analyzed at the material level, the correlation weakened. This paper develops an improved input–output-based hybrid (IOH) model to calculate the complete, accurate and material-specific Embodied Energy of 21 commonly used building materials. After calculating and evaluating...

identification of parameters for Embodied Energy measurement a literature review
Energy and Buildings, 2010Co-Authors: Manish K. Dixit, Sarel Lavy, Jose L Fernandezsolis, C CulpAbstract:The building construction industry consumes a large amount of resources and Energy and, owing to current global population growth trends, this situation is projected to deteriorate in the near future. Buildings consume approximately 40 percent of total global Energy: during the construction phase in the form of Embodied Energy and during the operation phase as operating Energy. Embodied Energy is expended in the processes of building material production (mining and manufacture), on-site delivery, construction and assembly on-site, renovation and final demolition. Recent studies have considered the significance of Embodied Energy inherent in building materials, with a specific focus on this fraction of sequestered Energy. Current interpretations of Embodied Energy are quite unclear and vary greatly, and Embodied Energy databases suffer from problems of variation and incomparability. Furthermore, there is no reliable template, standard or protocol regarding Embodied Energy computations that could address these problems in Embodied Energy inventories. This paper focuses on the analysis of existing literature in order to identify differing parameters so that development of a consistent and comparable database can be facilitated.

Embodied Energy assessment for macao s external trade
Renewable & Sustainable Energy Reviews, 2014Co-Authors: J.s. Li, X.f. Wu, Tasawar Hayat, A. Alsaedi, G Q Chen, Bashir AhmadAbstract:As a typical heterotrophic city, Macao׳s economic boom is fueled by external trade, which provides Macao with not only direct Energy products in forms of oil, gas and electricity, but also indirect Energy Embodied in other imports. However, the prevalent studies on Macao׳s Energy issues are confined to direct Energy inputs. Based on the most recent trade statistics and Embodied Energy intensity databases, a comprehensive assessment of Energy Embodied in Macao׳s external trade after its sovereignty handover is performed. The results show that Macao׳s Embodied Energy consumption is over 2 times as that of direct Energy consumption. The net Embodied Energy transfer via external trade from other regions to Macao increased from 6.31E+7GJ in 2000 to 8.75E+7GJ in 2011, while the Embodied Energy intensity dropped sharply from 1.02E+04GJ/ million USD to 2.40E+3GJ/million USD in the same period. Non-Energy-products and services rather than Energy products play the key role in Energy transfer, indicating that indirect Energy dominates Macao׳s Embodied Energy consumption. The largest Energy imbalance happens between Macao and mainland China. Given the nature of Macao׳s economy and escalating socio-economic development, it is suggested that the invisible but dominant indirect Energy consumption by Macao should be addressed by decision makers and included in future development strategies.

Energy and Buildings, 2013Co-Authors: J.s. Li, A. Alsaedi, Bashir Ahmad, G Q Chen, M.m. Jiang, Ling Shao, Xi JiAbstract:Abstract Presented in this paper is a detailed Embodied Energy consumption evaluation framework for building construction engineering. The building construction engineering comprises nine sub-projects, which are Structure and outside decoration engineering , Primary decoration engineering , Electrical engineering , Water supply and drainage engineering , HVAC engineering , Civil engineering , Municipal electrical engineering , Municipal water supply and drainage engineering and Gardening engineering . Our study chooses the construction engineering of a cluster of landmark commercial buildings in E-town, Beijing (Beijing Economic-Technological Development Area, BDA) as a case. As far as we know, this study is the first attempt to account the Embodied Energy consumption for building construction engineering based on the most exhaustive first-hand project data with about 1000 input items in the Bill of Quantities (BOQ). The Embodied Energy consumption of construction engineering is quantified as 7.15E+14 J. Structure and outside decoration engineering contributes more than half of the total Embodied Energy consumption, followed by Primary decoration engineering 's 23% and Electrical engineering 's 3%, respectively. As for the input items, the sum of the Embodied Energy consumption by steel, cement, lime and metal products is more than 3/4 of the total Embodied Energy consumption.

Renewable & Sustainable Energy Reviews, 2013Co-Authors: Luisa F Cabeza, Camila Barreneche, Laia Miro, Josep M Morera, Esther Bartoli, Ines A FernandezAbstract:This paper presents a review of the literature on low carbon and low Embodied Energy materials in buildings. Embodied Energy is defined and discussed vs. operating Energy of buildings and its growing importance due to the implementation of the Energy Building Performance Directive (EBPD) in Europe as example. The difficulty of measuring Embodied Energy and the difficulty in comparing published data are highlighted, showing an example of proposed new methodology found in the literature. Relationship between Embodied Energy and Embodied CO2 or CO2 footprint is defined. Different materials defined in the literature as low carbon materials are referred, such as cement and concrete, wood, bricks, rammed earth and sandstone. The review shows the research efforts found in the literature to develop new materials with less Embodied Energy. Finally, the effect of material substitution in the Embodied Energy of a building is reviewed in the literature.

affordable construction towards sustainable buildings review on Embodied Energy in building materials
Current Opinion in Environmental Sustainability, 2013Co-Authors: Luisa F Cabeza, Camila Barreneche, Laia Miro, Ines A Fernandez, Monica Martinez, Diana UrgevorsatzAbstract:Affordable construction has identified low Embodied Energy in materials as key issue. This review paper shows that even though there is a lack of research on this topic, Embodied Energy and carbon are studied in the context of buildings and construction materials. Moreover, comparison between studies is not possible due to the different assumptions used by the researchers, due to the fact that most studies are focused in a given location, and also due to the great variation between data presented in the Embodied Energy databases available. This paper shows different studies published in scientific journal papers and carried out around the world on the accounting of Embodied Energy in building materials. The paper includes the boundary of each of this study, including the location, type of material or building studied, and the conclusions found. Moreover, the paper discusses the definition of Embodied Energy and the significance of this concept in buildings.
