“…A reduction of 1.1 tons per 100 m 2 was seen in the project with semi-prefabrication, approximately 3.2% less than that emitted in the project with conventional construction. This reduction seems relatively small, and it is in line with other similar studies by Pons [44]. Pons conducted life cycle analysis of environmental impacts between three main industrialized technologies and a non-prefabricated one in school projects.…”

“…Pons conducted life cycle analysis of environmental impacts between three main industrialized technologies and a non-prefabricated one in school projects. Findings suggest that the emissions of prefabricated concrete technology were approximately 2% to 5% lower than those of nonprefabricated one [44]. Table 11 presents the results of the current and previous studies.…”

“…The small reduction might be attributed to the lower level of prefabrication. Pons' studies [44] also implied that a higher degree of prefabrication could contribute to greater benefits on environmental impact, such as GHG emissions.…”

Greenhouse gas (GHG) emissions in the construction stage will be more relatively significant over time.Different construction methods influence GHG emissions in the construction phase. This study investigates the differences of GHG emissions between prefabrication and conventional construction methods. This study sets a calculation boundary and five emission sources for the semi-prefabricated construction process: embodied emissions of building materials, transportation of building materials, transportation of construction waste and soil, transportation of prefabricated components, operation of equipment, and construction techniques. A quantitative model is then established using a process-based method. A semi-prefabrication project and a conventional construction project in China are employed for preliminary examination of the differences in GHG emissions. Results show that the semi-prefabrication method produces less GHG emissions per square meter compared with the conventional construction, with the former producing 336 kg/m 2 and the latter generating 368 kg/m 2 . The largest proportion of total GHG emissions comes from the embodied emissions of building materials, accounting for approximately 85%. Four elements that positively contribute to reduced emissions are the embodied GHG emissions of building materials, transportation of building materials, resource consumption of equipment and techniques, and transportation of waste and soil, accounting for 86.5%, 18.3%, 10.3%, and 0.2%, respectively, of reduced emissions; one a negative effect on reduced emissions is the transportation of prefabricated components, which offsets 15.3% of the total emissions reduction. Thus, adopting prefabricated construction methods contribute to significant environmental benefits on GHG emissions in this initial study.

“…Building construction causes high energy consumption and CO 2 emissions during the life cycle stages of construction, usage, and demolition (Pons and Wadel 2011). Thus, indicators should be designed to assess the impact of the TH site on the environment in terms of CO 2 emissions and energy consumption based on the life cycle assessment (LCA).…”

Many people lose their homes around the world every year because of natural disasters, such as earthquakes, tsunamis, and hurricanes. In the aftermath of a natural disaster, the displaced people (DP) have to move to temporary housing (TH) and do not have the ability to choose the settlement dimensions, distributions, neighborhood, or other characteristics of their TH. Additionally, post-disaster settlement construction causes neighborhood changes, environmental degradation, and large-scale public expenditures. This paper presents a new model to support decision makers in choosing site locations for TH. The model is capable of determining the optimal site location based on the integration of economic, social, and environmental aspects into the whole life cycle of these houses. The integrated value model for sustainable assessment (MIVES), a multicriteria decision making (MCDM) model, is used to assess the sustainability of the aforementioned aspects, and MIVES includes the value function concept, which permits indicator homogenization by taking into account the satisfaction of the involved stakeholders.

“…Prefabrication techniques had been widely adopted in the construction industry in various countries. Compared with conventional construction technologies, the inherent superiority of the technology include, among others, reducing labor demand [9], improving quality control [10], noise and dust reduction [11], higher standards for health and safety [11,12], construction waste reduction [13], time and cost savings [14], and low resource depletion [15]. In addition, some innovative technologies, such as parametric 3D modeling in building construction for precast concrete [16,17], dynamic simulation [18], and tracking and locating components in a precast storage yard utilizing radio frequency identification technology and global position system [19,20], have been effectively applied in the construction industrialization field.…”

The Index System for the Development Level Evaluation of Regional Construction Industrialization: A Case Study in Jiangsu, China

Abstract:In recent years, there have been concerns raised about construction industrialization in China, which have initiated a wave of policy change in both governmental and industrial organizations in order to change the mode of conventional construction. However, the current development level of regional construction industrialization (RCI) in China has not been well-characterized. This study screened preliminary index systems in five dimensions: technical, economic, sustainable, enterprise development and development environment. Based on the data gathered from the questionnaire surveys and subsequently analyzed, twenty-two critical evaluation indicators were identified. Analytic Hierarchy Process (AHP) was then employed to determine the weighting of each indicator. The evaluation method of the development level was formulated on the basis of the evaluation criteria. Jiangsu Province was used as an example in this study, with the development level of this province being comprehensively examined using a combination of the index system and evaluation method. The results show that Jiangsu has a relatively high RCI development level. The data from analysis scores of five dimensions and twenty-two indicators show that the index system is feasible, with evaluation results being consistent with actual practice. These findings provide a good practical reference for making decisions about how best to guide the development of RCI.
