“…However, it should be noted that the latter exhibits exceptional hardness [32] , rendering it more suitable for outdoor construction purposes. [6] [20] [24] The discussion also aims to determine the most appropriate BTM (Bamboo Treatment Method) that can be utilized to achieve the desired curvature, as previously mentioned. Various techniques, such as employing a bamboo slash with a 'V' notch on its culm, are being explored as potential methods for bending bamboo.…”

Bamboo is one of the fastest-growing natural construction materials and is locally available in most developing countries, including South America, Africa, and Asia. Bamboo is a “green gold” plant in the tropical forest. It is a fast-growing monocotyledon species belonging to the Gramineae family (Bambusoideae) and requires a short time for re-production. Bamboo’s physical strength provides builders from ancient times until today an opportunity to use bamboo as a natural and sustainable construction material for building houses and structures. Due to its capability to bend, bamboo is the most preferred material in vernacular construction and lately in Southeast Asia countries which borne new trend in building design. The built-environment professionals, namely landscape architects, architects, and engineers in Malaysia, still lack knowledge of bamboo, especially on bending capabilities, as one of the sustainable construction materials. Less concern was given to researching the capabilities of bamboo’s ability to bend, even though its strength is more than steel and provides various design opportunities compared to other sustainable materials. Different types of bamboo present different strength capacities. Therefore, the aims of this research is to compare and determine their strength capacity, bending criteria and species suitability for design and construction in Malaysia. This paper collects published literature on experimental studies on the different methods of Hot and Cold Bending Methods which allow bamboo to bend to suit designer needs and concentrate on Malaysian Dendrocalamus asper (Buluh Betung), which considered as tough and durable species, as the primary construction material for landscape structures. Bundle Bamboo Split (BBS), identified as one of the bending techniques adopted for an experimental project, using BBS of 0.8m radius, produces a prototype for a landscape structure. The findings indicate observation of works by a team of craftsmen trained by an expert in bamboo construction who used to produce bamboo structures from Bali, Indonesia, highlighted tools and procedures in bamboo construction. In short, this paper will also enhance the use of bamboo as an accessible, durable, creative and sustainable construction material that represents the local identity of Tropical Malaysia Landscape Architecture.

The new version of NBR 15527 (ABNT 2019) determines that any methodology used for the design of rainwater reservoirs must be performed considering the demand for rainwater resources. Thus, the objective of this study was to develop mathematical models for the design of rainwater reservoirs in residential buildings for all Brazilian states. Different use scenarios were simulated, which included drinking water demands of 100, 150, 200 and 300 litres per capita and rainwater replacement for drinking water at rates of 25, 35, 45 and 55%, according to rainfall data from the last decade. The optimal and maximal volumes of each scenario were calculated using the yield after spill (YAS) behavioural method. Based on the values of the volumes obtained, the studied municipalities were grouped, and for each group, the practical models were adjusted and evaluated using the coefficient of determination (R²) and the root mean square error (RMSE). A good adherence of the models to the observed data was observed, which simplified the estimation of the volume for rainwater reservoirs; practical applications demand that designs use discreet daily rainfall values.

Sustainable Rainwater Management and Life Cycle Assessment: Challenges and Perspectives

et al. 2023

View full text Add to dashboard Cite

Rainwater harvesting is a promising technique for more rational water use. However, its sustainability merits remain a subject of ongoing debate among researchers. Life cycle assessment (LCA), a method employed to measure the environmental impact of varying solutions, is helpful in this regard. Accordingly, this paper delivers an integrative review based on the PRISMA protocol, outlining challenges and potential avenues for the LCA application to rainwater harvesting. The central findings indicate that while residential buildings are most commonly examined, more consensus is needed on a uniform analytical framework. Furthermore, several benefits of rainwater are often not considered in LCA and need further exploration to understand possible synergies for its broader implementation. Finally, LCA integration with a life cycle cost assessment (LCCA) shows exciting results as it may be a more straightforward showcase of the benefits of an integrated assessment. It is concluded that specific details of the LCA of rainwater harvesting may still be simplistic. There is much work to be done in holistic assessments to prove the system’s sustainability.
