“…This result is justified, as the annual resource consumption of the construction industry worldwide accounts for 40% of the gravel, sand and stone, 25% of the timber and 16% of the water used [56], which makes the construction industry very resource intensive. This finding is consistent with previous findings of Akadiri et al [57], who described it as achieving more with less, and identified the driver as one the objectives to best achieve the concepts of sustainability in the building sector.…”

Abstract:Although sustainability is of utmost importance, anecdotal evidence suggests that the concept is not adequately implemented in many developing countries. This paper investigates industry stakeholders' awareness of the current state of, factors driving, and barriers hindering the adoption of sustainable construction (SC) in Cambodia. Using an empirical questionnaire survey targeting local construction professionals, respondents were invited to rate their level of awareness, knowledge and understanding of SC, as well as to rate the level of importance of 31 drivers and 10 barriers identified from the seminal literature. The data set was subjected to the relative importance index method. The results suggest that the industry-wide adoption of SC practices is poor, which is believed to be due to a lack of awareness and knowledge, and reluctance to adopt new sustainable technologies. Furthermore, more efforts must be put into the selection of more durable materials for the extension of buildings' lives and to minimize material consumption, as well as to develop energy-efficient buildings with minimal environmental impact and a healthy indoor environment, so that the ability of future generations to meet their own needs will not be compromised. The outcomes of this study have enriched knowledge about the current state of, drivers of, and barriers to sustainable construction in a typical developing economy. Although the outcomes of this study were a short scoping exercise, it has formed a significant base for future SC work within Cambodia.

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.

“…atmosphere through their life cycles (Dimoudi and Tompa, 2008;Pataki et al, 2009). Besides, compared to other sectors, there is the greatest potential of CO 2 emission reduction in the construction sector at a relative low expense, reaching 5.3-6.7 Gt CO 2 per year (IPCC, 2007), which makes the studies on CO 2 emission reduction from buildings be a hotspot for scientists, publics and policy makers.…”
