	Bamboo can be engineered to form products with improved and/or standardised mechanical, physical and aesthetic properties. As in the case for other lignocellulosic materials such as wood, bamboo poles (culms) with variable diameters, lengths and shapes can be transformed into straight edged engineered products with predictable properties for construction applications.

−	Engineered bamboo products (EBPs) and engineered wood products (EWPs) possess an intrinsic carbon storage capacity, as well as the potential for a lower embodied energy and lower carbon emissions from manufacturing than conventional construction products such as concrete or steel. For example, the carbon footprint of concrete and stainless steel (304) is two to ten times higher than that of bamboo plywood (a laminated EBP) or an indoor use plywood according to IDEMAT database (2016) [1].	+	Engineered bamboo products (EBPs) and engineered wood products (EWPs) possess an intrinsic carbon storage capacity, as well as the potential for a lower embodied energy and lower carbon emissions from manufacturing than conventional construction products such as concrete or steel.

	The embodied energy for producing one kilogramme (kg) of stainless steel is almost four times higher than that of producing one kilogramme of plywood [2] or bamboo plywood; 56.70 MJ/kg for the former and 15 MJ/kg and 15.5 for the laminated EBP [1].

−	In addition to bamboo’s remarkable environmental properties and high yield of carbon storing biomass when transformed into durable EBPs, recent research at the [http://www.bath.ac.uk/research/case-studies/bamboo-structural-material University of Bath] (UK) has demonstrated potential as a complementary material to wood (rather than a substitute) in structural applications [3]. Cross laminated Guadua-bamboo ([https://www.youtube.com/watch?v=YixPhThRb0A G-XLam]) panels (Figure 2) developed and tested at the university with the support of British firm [http://www.amphibiabase.co.uk/ Amphibia BASE] showed a two-fold increase in density and MOE when compared to analogous cross laminated (CLT) panels (M1 BSP crossplan by Mayr-Melnhof Holz) (Table 1). That is, the in-plane compression moduli of elasticity of these CLT panels in the main direction (Epc,0) and transverse direction (Epc,90) were about half of that of G-XLam3 and G-XLam5 panels (three and five layers); e.g. Epc,0 was 7.57GPa and 14.83 GPa for CLT3 and G-XLam3 panels.	+	In addition to bamboo’s remarkable environmental properties and high yield of carbon storing biomass when transformed into durable EBPs, recent research at the [http://www.bath.ac.uk/research/case-studies/bamboo-structural-material University of Bath] (UK) has demonstrated potential as a complementary material to wood (rather than a substitute) in structural applications [3].

−	Nevertheless, potential engineering applications for G-XLam panels include sandwich panels and stressed skin structures (e.g. monocoques, where thin but very stiff layers are separated by a core or internal structure that increases the second moment of area and reduces buckling. EBPs such as these G-XLam panels present a new approach to the use of bamboo in structural applications, where bamboo is not seen as substitute, but a complementary material that in combination with wood and/or lightweight cores can provide the required stiffness with reduced cross-sections.	+	Nevertheless, potential engineering applications for G-XLam panels include sandwich panels and stressed skin structures (e.g. monocoques, where thin but very stiff layers are separated by a core or internal structure that increases the second moment of area and reduces buckling.
