Special Issue Information

Dear Colleagues,

We are facing an unprecedented challenge as the climate rapidly changes and natural environments deteriorate at alarming rates, while the achievement of a sustainable human society moves further out of our reach. The need for rapid action and regenerative solutions that can deliver results on a short timescale are needed more than ever. One of the major commitments of nations worldwide is to achieve carbon neutrality within their built environments in the coming decades. It is clear how this commitment can only be fulfilled with the implementation of bio-based materials. These unconventional materials not only have the ability to lower the carbon footprint when used in building, but also have the capacity of storing carbon during their service life and removing large amount of CO2 due to their fast growth. Bio-based construction materials, such as bamboo, hemp, and straw, etc., can provide a wide range of applications, from structural purposes to thermal insulation. Bio-based solutions can be contextualized to respond to specific needs of different geographies, thus providing appropriate responses to the challenges faced in each region. These promising solutions still require further development and understanding of the scope of their benefits along the value chain before being promoted as sustainable development solutions.

The need for solutions to achieve net-zero-carbon built environments is more imperative than ever. We recognize that approaches utilizing fast-growing, bio-based materials can make a significant contribution to achieving this goal. Nevertheless, we see that efforts to promote these materials are spread across very different fields of knowledge. With the present Special Issue, we aim to highlight the potential of fast-growing, bio-based materials in novel applications in the built environment, especially in building. Moreover, we would like to target the main positive aspects of these materials, such as their circularity and contribution to the implementation of new bio-economies.

With this Special Issue, we aim to bring attention to the potential contributions that fast-growing, bio-based material can provide while creating a repository of knowledge that can help decision-makers and pave the way towards a sustainable built environment.

We are pleased to invite you to submit an original contribution to this Special Issue addressing topics in the fields of material science, buildings physics, structural applications, value chain analysis, circular and bio-economies, as well as criticality and land-use competition.

Bamboo is considered a sustainable construction material due to its ability to grow quickly and its mechanical properties that are comparable to timber. Contributing to the current effort to establish structural bamboo standards in the National Structural Code of the Philippines (NSCP), this study establishes the characteristic compressive strength of four bamboo species: Bambusa vulgaris (36 samples), Dendrocalamus asper (36 samples), Bambusa blumeana (94 samples), and Guadua angustifolia Kunth (30 samples). The samples were subjected to compressive loading following ISO 22157-1 (2017). The characteristic compressive strength values obtained, according to ISO 12122-1 (2014), were 40.35 MPa for B. vulgaris, 40.21 MPa for D. asper, 46.63 MPa for B. blumeana, and 36.99 MPa for G. angustifolia Kunth. Simple linear analysis, one-way ANOVA, and Welch’s t-test were used to analyze the correlation models and establish a comparative analysis of the effects of nodes and geometric and physical properties on the compressive strength of bamboo samples. In comparisons of the characteristic compressive strengths obtained from this study to the strengths of unseasoned structural timber of Philippine woods, all bamboo species showed higher strength values than did other woods, and bamboos thus have great potential as an alternative construction material to timber.

The Philippines faces a significant shortage of affordable housing, and with the growing urgency brought by climate change, there is a pressing need for more sustainable and affordable building solutions. One promising option is cement bamboo frame buildings, which blend traditional bamboo building methods with modern materials. This approach is already being implemented in social housing projects in the Philippines. Dynamic lifecycle assessment (DLCA) calculations show that these bamboo buildings can effectively reduce overall CO2 emissions. Before a building’s end of life, biogenic effects offset approximately 43% of its total production emissions, while the temporary carbon storage afforded by these biogenic materials further reduces total emissions by 14%. In comparison to concrete brick buildings, bamboo constructions reduce emissions by 70%. Transforming an unmanaged bamboo plantation into a managed plantation can potentially triple the capacity for long-term CO2 storage in biogenic materials and further reduce net emissions by replacing concrete with bamboo as the main construction material. Thus, bamboo construction offers a potent, economically viable carbon offsetting strategy for social housing projects. Full article
