“…As bamboo is often considered as an alternative to wood, and indeed analogous to wood with respect to materials development, testing standards, and end-use (but importantly not in microstructure and mechanical behaviour) [1,2,7], a comparison of the thermal properties of engineered bamboo composites with engineered wood composites is useful.…”

“…Bamboo is a rapidly growing and renewable material with increasing interest for its use as a structural building material [1][2][3][4][5]. As a natural, cellulosic material, bamboo is comparable to timber; however, bamboo species belong to the family of grasses and differ from timber in both gross morphology and cellular structure: a comparison is given in Fig.…”

Here we characterise the thermal properties of engineered bamboo panels produced in Canada, China, and Colombia. Specimens are processed from either Moso or Guadua bamboo into multi-layered panels for use as cladding, flooring or walling. We utilise the transient plane source method to measure their thermal properties and confirm a linear relationship between density and thermal conductivity. Furthermore, we predict the thermal conductivity of a three-phase composite material, as these engineered bamboo products can be described, using micromechanical analysis. This provides important insights on density-thermal conductivity relations in bamboo, and for the first time, enables us to determine the fundamental thermal properties of the bamboo cell wall. Moreover, the density-conductivity relations in bamboo and engineered bamboo products are compared to wood and other engineered wood products. We find that bamboo composites present specific characteristics, for example lower conductivities-particularly at high density-than equivalent timber products. These characteristics are potentially of great interest for low-energy building design. This manuscript fills a gap in existing knowledge on the thermal transport properties of engineered bamboo products, which is critical for both material development and building design.

“…Bamboo bars used in the project were only divided and cut by its length, but the natural sectional-shape of the material was left as is. Consequently, each bar's diameters were different to each other, leading to the possibility of module members not fitting to its designated joints and/or connections [19].…”

Abstract. Bamboo is considered as a sustainable material in the world of construction, and it is vastly available in Indonesia. The general utilization of the material is increasingly frequent, however, its usage as a deployable structure-a recently-developed use of bamboo, is still untapped. This paper presents a report on a deployable bamboo structure project, covering the entire building life-cycle phase. The cycle encompasses the designing; fabrication; transportation; construction; operation and maintenance; as well as a plan for future re-use. The building is made of a configuration of the structural module, each being a folding set of bars which could be reduced in size to fit into vehicles for eas y transportation. Each structural module was made of Gigantochloa apus bamboo. The fabrication, transportation, and construction phase require by a minimum of three workers. The fabrication and construction phase require three hours and fifteen minutes respectively. The building is utilized as cafeteria stands, the operation and maintenance phase started since early March 2017. The maintenance plan is scheduled on a monthly basis, focusing on the inspection of the locking mechanism element and the entire structural integrity. The building is designed to allow disassembly process so that it is reusable in the future.

“…In comparison with wood building materials, bamboo has a stable size, good rigidity, and is abrasion-resistant (Fuentes et al 2015;Li et al 2015;Sharma et al 2015). Naturally, laminated bamboo has been recognized worldwide as a sustainable green building material and therefore is a very important material in promoting forest product transformation for the construction industries (Nath et al 2015).…”

The bamboo industry plays a significant strategic role in the world's economy. Laminated bamboo, with increasing yearly yields, is the intermediate material for bamboo products such as furniture, floor board, and container floor. The trilaminar straight joint glued-laminated bamboo production line is the leading enterprise in Fujian Province, and it was used to conduct a load analysis of the data collected from a year's production, based on the life cycle assessment system. The results show that the processing of glued-laminated bamboo contributes notably to the acidification potential, eutrophication potential, global warming potential, and photochemical ozone creation potential, whereas resource depletion and ozone depletion are affected by the urea-formaldehyde resin adhesive, among which the urea contributes the most. As for processing, carbonization, desiccation, and thermo-compression, these have the greatest impacts on the environmental load, with a total contribution rate of greater than 67%, as the main source for the power depletion is from the processing of fossil fuel. In addition, the oxynitride, phosphide, sulfide, aromatic hydrocarbon, etc., that are discharged from the reaction intensify the eutrophication potential, the photochemical ozone creation potential, and the acidification potential.
