“…Many interrelated factors create drivers or barriers to the adoption of unconventional approaches in construction [56]. In the case of reuse, uncertainties over lead-in times, cost, and consistency of quantity and quality appear to be severe constraints on demand from risk-averse mainstream construction [57].…”

Abstract:The construction industry uses more resources and produces more waste than any other industrial sector; sustainable development depends on the reduction of both, while providing for a growing global population. The reuse of existing building components could support this goal. However, it is difficult to reclaim components from demolition, and materials remain cheap compared with labour, so new approaches are needed for reuse to be implemented beyond niche projects. This study therefore reviews waste interventions. Multiple case studies, spanning new builds and refurbishment, were undertaken to examine systemic mechanisms that lead to components being discarded. Evidence from fieldwork observations, waste documentation, and interviews indicates that the generators of unwanted components effectively decide their fate, and a failure to identify components in advance, uncertainty over usefulness, the perception of cost and programme risk in reclamation, and the preferential order of the waste hierarchy mean that the decision to discard to waste management goes unchallenged. A triage process is proposed to capture timely information about existing building components to be discarded, make this information visible to a wide community, and determine usefulness by focusing creativity already present in the industry on an exhaustive examination of component reusability and upcyclability.

“…In 2014, the global annual production of CLT was 600,000 cubic metres, and this is expected to reach 1,000,000 cubic metres by 2016 [17]. CLT was introduced to the UK in 2001 and the material use is growing at a rate of 25% per annum [1]. CLT based construction has also experienced rapid market growth more recently in the Australian, US, and Canadian markets.…”

This paper aims to investigate the energy saving and carbon reduction performance of cross-laminated timber residential buildings in the severe cold region of China through a computational simulation approach. The authors selected Harbin as the simulation environment, designed reference residential buildings with different storeys which were constructed using reinforced concrete (RC) and cross-laminated timber (CLT) systems, then simulated the energy performance using the commercial software IES TM and finally made comparisions between the RC and CLT buildings. The results show that the estimated energy consumption and carbon emissions for CLT buildings are 9.9% and 13.2% lower than those of RC buildings in view of life-cycle assessment. This indicates that the CLT construction system has good potential for energy saving when compared to RC in the severe cold region of China. The energy efficiency of residential buildings is closely related to the height for both RC and CLT buildings. In spite of the higher cost of materials for high-rise buildings, both RC and CLT tall residential buildings have better energy efficiency than low-rise and mid-rise buildings in the severe cold region of China.

“…However, the industry's reputation for conservatism suggests that the required change may not occur unprompted. Previous research has shown the importance of capability, opportunity and motivation for delivery of construction innovation on construction projects (2). These aspects are explored in the context of a case study.…”
