The Use of Polyvinylchloride (PVC) Claddings and Polystyrene Wall Panels as Alternative Building Materials to Wood: A Strategy to Combat Climate Change.

Abstract

Unprecedented variations in climate are currently being experienced all over the world and Nigeria is not an exemption from this global trend. Generally, researchers have pointed to human activities as the major contributor. The paper evaluates occupants’ perception and acceptability of Polyvinylchloride (PVC) claddings and Polystyrene wall units as substitutes for wood based products at Royal Estate in Lagos.This paper also examines alternative building materials as a remedy to deforestation in building construction activities in Nigeria with a view to highlighting their mutilating effect on climate change. A total of 20 dwelling units were studied; using Post Occupancy Evaluation (POE) research method. Results show that 90% of respondents rated as ‘good’ their level of acceptability and awareness of these materials while quality and durability were rated equally as ‘good’ by 75% of total respondents.From the general high level of acceptability of Polyvinylchloride (PVC) claddings and Polystyrene wall units, if popularized could serve as alternative building materials. This may reduce the dependence on wood which could therefore, mitigate against the negative impact of climate change.Government has been advised to make and implement reforestation policies so that trees could serve as carbon sink.
