understanding barriers affecting the selection of Sustainable Materials in building projects
Journal of building engineering, 2015Co-Authors: Peter O. AkadiriAbstract:Abstract The selection of Sustainable building Materials has been identified as an important strategy in the design of a building. Although the sustainability imperative is gaining in importance, there are still major barriers preventing this’‘new style’ architectural practice becoming the norm. This paper examines the major barriers encountered in the selection of Sustainable building Materials among building construction professionals in Nigeria. A questionnaire survey was developed to capture the perception of construction professionals regarding the significance of the identified barriers as it affects the selection and use of Sustainable building Materials. Case studies of three completed building projects were conducted with design team to validate the result of the survey. Research results show that perception of extra cost being incurred and lack of Sustainable Material information are identified as the top barriers to Sustainable Materials selection. The paper concludes with suggestions and actions that can help overcome these existing barriers.

Multi-criteria evaluation model for the selection of Sustainable Materials for building projects
Automation in Construction, 2013Co-Authors: Peter O. Akadiri, Paul O. Olomolaiye, Ezekiel A. ChinyioAbstract:Sustainable Material selection represents an important strategy in building design. Current building Materials selection methods fail to provide adequate solutions for two major issues: assessment based on sustainability principles, and the process of prioritizing and assigning weights to relevant assessment criteria. This paper proposes a building Material selection model based on the fuzzy extended analytical hierarchy process (FEAHP) techniques, with a view to providing solutions for these two issues. Assessment criteria are identified based on Sustainable triple bottom line (TBL) approach and the need of building stakeholders. A questionnaire survey of building experts is conducted to assess the relative importance of the criteria and aggregate them into six independent assessment factors. The FEAHP is used to prioritize and assign important weightings for the identified criteria. A numerical example, illustrating the implementation of the model is given. The proposed model provides guidance to building designers in selecting Sustainable building Materials. © 2012 Elsevier B.V. All rights reserved.

out of grade sawn pine a state of the art review on challenges and new opportunities in cross laminated timber clt
Construction and Building Materials, 2019Co-Authors: Rebecca Cherry, Allan Manalo, W Karunasena, Geoff StringerAbstract:Abstract Plantation softwood is the future timber Material resource for building and construction. However, significant volumes of sawn softwood are considered out-of-grade and sold at a loss. New approaches and methods need to be implemented to value-add out-of-grade timber and increase structural yield from existing plantations. This paper provides a critical review of out-of-grade characteristics of pine timber to gain an understanding of the strengths and weaknesses of this resource as a structural building Material. Methods to incorporate out-of-grade timber into current building systems are presented and building technologies that can facilitate this use are identified. Finally, it discusses developments and important considerations for design of cross laminated timber (CLT) as a prime example of a building system with good capacity to incorporate high volumes of out-of-grade timber. This provides critical information for the maximum utilisation of sawn out-of-grade pine and is anticipated to create new opportunities that can effectively incorporate this renewable and Sustainable Material resource into innovative building systems and technologies.

static fatigue and impact behaviour of an autoclaved flax fibre reinforced composite for aerospace engineering
Composites Part B-engineering, 2020Co-Authors: Tulio H Panzera, Thomas Jeannin, Xavier Gabrion, Vincent Placet, Chrystel D L Remillat, Ian R Farrow, Fabrizio ScarpaAbstract:Abstract This work describes the physical and mechanical characterization of unidirectional [0]12 and crossply [(0/90)3/ 0 ‾ ]S flax fibre reinforced composites fabricated in autoclave using a prepreg flax tape impregnated with fire retardant epoxy polymer. Tensile, bending and impact properties are evaluated along the longitudinal and transverse fibre directions. The tensile-tensile fatigue behaviour is characterised along the fibre direction. Physical and specific properties are also assessed to identify the potential characteristics of these bio-based composites for lightweight and secondary loadbearing applications. The robust manufacturing process described in this work, coupled with precision laser cutting, makes this type of composite a promising Sustainable Material for aircraft, transport and lightweight construction designs.

Sustainable Material selection for construction industry a hybrid multi criteria decision making approach
Renewable & Sustainable Energy Reviews, 2016Co-Authors: Kannan Govindan, Madan K Shankar, Devika KannanAbstract:Urbanization and globalization has led to a rapid development in the construction industry. Many strategies have been proposed to improve cost effectiveness in this sector. Over the last decade, cost concerns have been balanced with a growing debate on the necessity for Sustainable construction practices. Because of depleting resources and environmental concerns, researchers and practitioners have begun to explore Sustainable construction strategies. Among these strategies is the selection of Sustainable Materials which play a vital role in a building׳s environmental footprint. In the UAE in particular, there is an ongoing demand to select the best Sustainable construction Materials because the industry is growing so rapidly in this nation. Thus, the main intent of this paper is to propose a model to evaluate the best Sustainable construction Material based on Sustainable indicators through a hybrid multi criteria decision making (MCDM) methodology with a specific examination of the UAE. The indicators collected from existing literatures were used in evaluation of Sustainable construction Materials with the assistance of construction sector-based respondents. The proposed framework was validated with a case study company, and the results were compared to the existing literatures and to feedback from the respondents. Finally, the study concludes with an assessment of its own limitations along with the identification of some useful managerial implications; it sheds some light on future possible enhancements in the theme of Sustainable construction in the context of UAE.
