A green building material (GBM) is an ecological, health-promoting, recycled, or high-performance building material that impacts the material selection to cover all three pillars (3Ps) of ...sustainability. The absence of clear instructions for GBMs and the difficulty of precision adjustments of GBM criteria with 3Ps sustainability make GBM selection a challenge. In addition, the consideration of all sustainability factors in GBM selection is a multi-criteria decision problem that requires mathematical techniques such as the multi criteria decision making (MCDM) method.
This study applies a hybrid MCDM methodology to resolve multiple incompatible and conflicting GBM criteria to align with 3Ps sustainability. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) was used to analyze the efficacy of and interrelationship between GBM criteria. This tool is a hybrid model using fuzzy analytic network process (FANP) for aligning and ranking GBM criteria based on 3Ps sustainability. Additionally, the study inspects four groups of professionals in Malaysia who involved in GBM selection and modified one of the oldest GBM criteria models considering the criteria identified from a comprehensive literature review. The results show that the relationship between GBMs and sustainability criteria are different based on the separate 3Ps of sustainability. The evaluation and results provide a valuable reference for building professionals to enhance sustainable construction through green materials.

Infrastructure is the backbone of economic growth, which should be resurrected through green competency to rethink the infrastructure strategy and economic prosperity in dealing with local and global ...issues. There are several linkages such as energy efficiency between Green Infrastructure (GI) and Green Economy (GE) which have absolutely delivered remarkable rewards and influences in environmental, social, economic pillar of sustainable development (SD). However, these influences have not been cleared and unknown in priors’ literature. This study proposes a methodological approach to deliberate: the Analytical Network Process (ANP) to prioritise GI criteria with considering their mutual influences, which would be primed to the enactment of GE in the context of SD; and the Adaptive Neuro-Fuzzy Inference Systems (ANFIS) to implement GE in SD context. The ANP results as inputs info for ANFIS method indicated that the majority of effectiveness belonged to four primary GI criteria (approximately more than 80%), namely, Affordability, Resource Efficiency, Energy Efficiency, and Air Quality. The ANFIS results for achieving each GE indicators showed that the most effective combination of upward interaction among GI criteria are belonged to: Affordability with Resource Efficiency (Eco-Environment indicator), Energy Efficiency with Resource Efficiency (Socio-Environment indicator), and Affordability with Energy Efficiency (Socio-Economic indicator). In conclusion, the best interaction for GE implementation belonged to Socio-Environment and Eco-Environment indicators through the greatest interface among Affordability, Energy Efficiency, and Resource Efficiency.

Relentless environmental concerns, steep hike in fossil fuel price, and increasing demand of non-renewable fossil fuels consumption have dramatically increased global search for alternative energies. ...The world requests ever growing energy supplies to sustain economic development and improvement. Renewable and sustainable energy ever more becoming accepted and established a decisive place in energy system of the word due to ecologicallyresponsiveinsight and a decrease in equipment expenses. Consistent with its endowment of energy resources, each country tried to figure out its own energy portfolio and employing technologies, which are economically viable and socially equitable, and have minimal adverse impacts. This article attempts to review all possible renewable energy sources as a substitute of the current energy profile (coal, natural gas, and petroleum) in Afghanistan. The study found Afghanistan power sector as one of the least development sector which its inadequate status is preventing the development of the country as well. Eventhough, the energy is not the only panacea, but cost effective energies in abundant quantity and quality on sustainable foundation will help to reach to demand socio-economic development. The results indicate that Afghanistan due to its natural and geographical situations enjoys important prospective for renewable energy bases such as solar, wind, geothermal and micro hydro power. Renewable energies could offer the ultimate solution for Afghanistan in general, and rural areas in actual. But, switch to altered forms of energy is grounded in multifaceted interations. The study indicates number of issues such as great upfront charges, absence of providers, insufficient funding appliances, and feebleindorsed and methodologicalcapability overwhelm and affected the use of renewable energies and technologies in Afghanistan. However, with sufficient investment and practical stages by government, andnongovernment agencies and the public encourage, these unbound sources could play a vital role not only in Afghanistan's energy supply, but also in poverty reduction, social and political stability, and improving living standard.

•The polyhydroxybutyrate is targeted as matrix for green composite.•The mechanical test of KBFw/EFB hybrid reinforced PHB biocomposite with 11 layers is determined that it has capability to replace ...with some wood and woody production.
Green or Biocomposite materials encompass biopolymers and natural fibers (NFs) from renewable resources, which is helped to eliminate non-renewable waste, reduce raw material usage, and lessen greenhouse gas emissions. This paper aimed to assess and develop specific biocomposite in terms of mechanical properties, which prepared by lamination and compression molding method. The woven kenaf bast fibre (KBFw) is deliberated as reinforcement in this study due to the high tensile strength which was hybridized with oil palm empty fruit bunches (EFB) due to high toughness of EFB for covering the impact properties of biocomposite. The polyhydroxybutyrate (PHB) is a common biodegradable polymer that is targeted as matrix for green composite. The triethyl citrate (TEC) was chosen as plasticizer for improving flexibility and handling of PHB films. The scanning electron microscope was used to understand and investigate the tensile-fractured surface of different hybrid biocomposite. The results show that the tensile and flexural properties would be increase when NFs with higher tensile strength was used as skin fibre in term of hybrid composite. Conclusively, the flexural stiffness of biocomposite increase when the KBFw PHB biocomposite is hybrid with FEB reinforcement. The tensile and flexural test of KBFw/EFB hybrid reinforced PHB biocomposite with 11 layers (sample E) is determined that sample E has capability to replace with some wood and woody production.
