This study seeks to better understand the determinants of green building technology (GBT) adoption intention of construction developers in developing countries. In order to address these objectives, this study integrates the Diffusion of Innovation theory, the theory of Resource-based View, and the Resource Dependence Theory to analyze and construct the theoretical model of developers’ intentions to adopt GBTs from three perspectives, namely, technological, organizational, and environmental. The model was tested using survey data collected from 142 experienced managers in Vietnam. Data analysis was performed by SEM using the partial least squares (PLS) approach. The findings show that perceived GBT advantages, perceived GBT disadvantages, top management leadership, government support, project partners’ green building readiness, and social demand of green buildings are the significant factors that affect GBT adoption intention by developers. However, organizational GBT resource and GBT market readiness have no significant effect on developers’ GBT adoption intention. Theoretical and practical implications and limitations of the research are discussed, and suggestions for future research are also proposed.
The control of the concrete temperature to prevent cracking can be viewed as principal goal in the design and construction of mass concrete. This paper researched on a novel technique for minimizing both the difference and the peak value of the temperature in mass concrete. Following this technique, the mass concrete is divided horizontally into two parts of different concrete mixtures but having the same strength grade. While the upper part is the normal heat concrete, the lower part can be considered as the low heat concrete which generate lower hydration heat than the upper part does. The influences of (i) concrete proportions of the layers; and (ii) thickness of the upper layer on the thermal behavior in mass concrete are two important aspects of the technique. Therefore, these two points represent important objectives of our present research. For this purpose, some numerical simulations with finite element method (FEM) and an in-situ experiment on a mass concrete block were performed. As a result, the simulated temperature field was validated by comparing with the experimental result and the principles of layers’ mixtures and thickness were drawn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
