Alternative Building Materials (ABM): Towards Adoption of Common Terminology and Definitions

Abstract

There are differences in the definitions of Alternative Building Materials (ABM) and differences in the terminologies that are used in describing ABM by different researchers in the construction industry. ABM is a generic term, which is characterised of or relating to a class or group of building materials, not really specific. It encompasses building and construction materials that in literature are referred to by different names such as alternative materials, local building materials, unconventional building materials, alternative residential construction materials, sustainable building materials, indigenous building materials, vernacular building materials, green building materials, environmentally responsible building materials, eco-friendly building materials, etc. The research employed systematic literature review and content analysis to generate and analysedall the necessary information as the methodology.  A working (operational) definition of Alternative Building Materials is being offered as building materials that are an alternative to conventional building materials in the form of total or partial substitution of the materials or its constituents for the purpose of reducing the cost, addressing environmental issues or dealing with lack of conventional materials. The characteristics of ABM have been identified to include low or no chemical emissions that can lead to poor indoor air quality, recycled content (post-consumer and pre-consumer), no CFC, HCFC, or other ozone depleting substances content, low embodied energy, locally produced, possibility of repairs and replacements with local means and social acceptability amongst others. Some of the benefits of utilizing ABM include; low embodied energy (often leading to reduced greenhouse gas emissions), ease of construction, widespread availability and low cost.
