“…The influence of the behavioral factor on the production of construction waste has been more widely studied and also confirmed in other scientific studies [24,25,29,30]. In 2004, a survey conducted in Singapore among general contractors identified four main sources of construction waste: (1) design, (2) production and delivery, (3) material management, and (4) construction [26].…”

“…In 2004, a survey conducted in Singapore among general contractors identified four main sources of construction waste: (1) design, (2) production and delivery, (3) material management, and (4) construction [26]. The results of these both studies, which were carried out in 1994 and 1996, and following ones confirmed that the maximum number of sources of the construction waste occur at the design stage [23,[27][28][29]. Based on a subject literature review [21][22][23][24][25][26][27][28][31][32][33], 13 methods of reducing the amount of construction waste used in construction companies were found.…”

The article presents the analysis of the dependence between methods of reducing construction waste and the size of the construction enterprise. The analysis was carried out for the following construction products: steel, concrete, wood, and small-sized (ceramic, concrete) and finishing (ceramic and stone tiles) products. Based on the literature review, the 13 most frequently used methods of reducing construction waste were identified. Surveys were then conducted among 140 construction enterprises. The research was conducted in Sharjah in the United Arab Emirates. In order to test whether there is a relationship between the used waste-reduction method for a given construction product and the size of the enterprise, the Pearson chi-square test of independence was used. The null hypothesis and the alternative hypothesis were formulated, and the critical level of significance α = 0.05 was adopted. The results were statistically significant for 7 methods of reducing construction waste. The identified methods include appropriate storage, the training of employees in the field of waste management, the use of monitoring systems, the appropriate transport and unloading of products, the appropriate involvement of subcontractors, the use of prefabricated elements, and the reuse of products on the construction site. Based on the conducted research, it was found that these methods are more often used with an increase in the size of the enterprise. The presented analysis emphasizes the urgent need to improve, integrate, and adjust the promotion of both the reduction of construction waste and the benefits of this reduction in construction enterprises, especially those of the smallest size.

“…Multiple scholars report lack of client awareness and, in turn, lack of demand as barriers to the implementation of eco-design in the building sector [22][23][24][25]. Agyekum et al (2019) argue that when the clients are unaware of the possibilities for eco-designing buildings, or the potential benefits from this, it is difficult for them to show an interest in the subject and thereby also create a market demand [21].…”

“…However, the knowledge is lacking and is thereby acting as a barrier to eco-design implementation [17,21,22,[25][26][27][28]31,32]. Further barriers to eco-design implementation are lack of professional skills [17,23,26] and lack of cooperation within the design team [18,23,30]. Jusselme et al (2020) argue that collaboration is lacking at the conceptual design stage, as architects are reluctant to involve engineers at this early stage of the design [30].…”

How Lack of Knowledge and Tools Hinders the Eco-Design of Buildings—A Systematic Review

et al. 2021

The building sector is responsible for extensive resource consumption and waste generation, resulting in high pressure on the environment. A way to potentially mitigate this is by including environmental considerations during building design through the concept known as eco-design. Despite the multiple available approaches of eco-design, the latter is not easily achieved in the building sector. The objective of this paper is to identify and discuss what barriers are currently hindering the implementation of eco-design in the building sector and by which measures building designers can include environmental considerations in their design process. Through a systematic literature review, several barriers to implementation were identified, the main ones being lack of suitable legislation, lack of knowledge amongst building designers, and lack of suitable tools for designers to use. Furthermore, two specific tools were identified that allow the inclusion of environmental consideration in building design, along with nine design strategies providing qualitative guidance on how to potentially minimize energy and material consumption, as well as waste generation. This paper contributes a holistic overview of the major barriers to and existing tools and method for the eco-design of buildings, and provides guidance for both future research and practice.

The consistent growth of the construction sector during the last decades has generated massive waste that severely impacts the environment. Globally, construction activities generate around 30% of the overall waste annually, and the numbers are expected to increase due to population growth projections and the need for infrastructure developments. As a matter of fact, the causes of waste can be grouped into seven categories namely, design-related, procurement-related, human-related, handling and storage, site conditions, management-related, and due to other external factors, such as the effect of weather and accidents. In addition, construction waste types are influenced by project type, size, and construction method. To mitigate the impacts of construction waste, a plethora of practices have been recommended, including innovations for procurement, design, and construction. The present study scrutinises potential opportunities for minimising construction waste and proposes future sustainability enhancement related to construction activities. A pivotal contribution of this study is the creation of a matrix that links the identified causes of construction waste with sustainability practices, offering a comprehensive insight for effectively reducing waste and enhancing the sustainability of construction activities.
