Construction Efficiency

Construction industry is the consuming large amounts of natural resources and at the expense of a heavy environmental burden. Therefore, we need to keep a balance between creating economic benefit through construction and focusing on the influence to the environment with the aim of the value of carbon emissions maximize. The paper puts forward carbon efficiency which provides a linkage between carbon reduction and value creation of construction effectively can reflect construction efficiency. The essence of carbon efficiency is using the lowest environment output to build a construction. Through analysing two cases, result shows that carbon efficiency of prefabricated construction is higher than the conventional construction’s, which improves 25%. Besides, the measures are provided to improve the carbon efficiency of constructing. Enhancing the precast level, implementing prefabricated components standardized, optimizing site management is the main key to realize the low carbon construction.

As the largest carbon emitter in the world, China is confronted with great challenges of mitigating carbon emissions, especially from its construction industry. Yet, the understanding of carbon emissions in the construction industry remains limited. As one of the first few attempts, this paper contributes to the literature by identifying the determinants of carbon emissions in the Chinese construction industry from the perspective of spatial spillover effects. A panel dataset of 30 provinces or municipalities from 2005 to 2015 was used for the analysis. We found that there is a significant and positive spatial autocorrelation of carbon emissions. The local Moran’s I showed local agglomeration characteristics of H-H (high-high) and L-L (low-low). The indicators of population density, economic growth, energy structure, and industrial structure had either direct or indirect effects on carbon emissions. In particular, we found that low-carbon technology innovation significantly reduces carbon emissions, both in local and neighboring regions. We also found that the industry agglomeration significantly increases carbon emissions in the local regions. Our results imply that the Chinese government can reduce carbon emissions by encouraging low-carbon technology innovations. Meanwhile, our results also highlight the negative environmental impacts of the current policies to promote industry agglomeration.

Abstract Low-carbon innovation plays an essential role in carbon reduction worldwide. This study investigates how low-carbon innovation affects carbon emissions by the Dynamic Spatial Durbin Model based on 30 Chinese provinces from 2007 to 2017. The empirical results show that: First, there exists provincial agglomeration of carbon emissions. High emission provinces concentrate in major economic zones and energy extraction areas. Second, low-carbon innovation decreases carbon emissions in general. The spillover effects are higher than the direct effects in the short run, but the spillover effects are not significant in the long run. Third, the environmental Kuznets curve (EKC) hypothesis is valid both in the short-run and long-run. Ninety percent of the provinces' GDP is above the inflection point by 2017. The summary of policy implications is as follows. First, targeted incentives for R&D in low-carbon technologies are needed; Second, the externalities of low-carbon innovation require attention; Third, energy transition need to be promoted as soon as possible.

PurposeThe demand to reduce carbon emissions has become an increasingly important social factor due to the unprecedented impacts of climate change. However, most existing publications have focused on minimizing emissions during the operational phase of buildings. At the same time, there is a lack of comprehensive research conducted on carbon emissions, specifically during the construction phase. The purpose of this paper is to identify, review and classify current practices related to carbon emissions management in construction operations to gain greater insight into how to reduce and mitigate emissions and achieve more sustainable solutions.Design/methodology/approachThis study reviewed the published literature on carbon emissions from construction. A total of 198 bibliographic records were extracted from the Scopus collection database and analyzed using Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). PRISMA is used as a basis for reporting possible trends, research methods and strategies used in published literatures. A total of 99 papers related to carbon emissions in the construction operations were further reviewed and analyzed. This review paper draws on existing research and identifies current carbon management patterns in construction projects.FindingsData indicated an upward trend in the number of publications in carbon emissions research during the last few years, particularly in 2015, 2017 and 2019. The most significant contributions to the domain were reported from China, Europe and the USA. This paper found that most studies conduct the Life Cycle Assessment (LCA) method to estimate carbon emissions. This paper found that the primary studies have focused on construction machinery and equipment emissions. The strategies such as establishing uniform standards for carbon emissions policies and regulations, equipment and logistic planning and low carbon design material will potentially impact carbon emissions reductions.Practical implicationsThis paper provides information that will be beneficial for the construction industry to design and manage construction operations. It will also be of interest to those looking to reduce or manage construction emissions.Originality/valueAlthough there is a diversity of current thinking related to the practical estimation and management of carbon emissions in construction projects, there is no consolidated set of keys of standardized carbon emissions management in practice. By assessing the existing paradigms of carbon assessment methods and tactics in the construction industry, this study contributed to the existing knowledge base by providing insights into current techniques in the construction sector for monitoring and mitigating emissions.
