Evaluation of Green Building Technologies (GBTS) By Construction Professionals in Southwest Nigeria

Abstract

The adoption of Green Building Technologies (GBTs) is increasingly recognized as a promising approach to enhancing the sustainability performance of buildings, generating significant interest in the global construction community. However, barriers such as the lack of local expertise in green building practices and insufficient awareness highlight the need for effective strategies to promote broader adoption of GBTs in building development. This study aims to identify the benefits of adopting GBTs and assess their level of implementation by professionals in Southwest Nigeria. Following a comprehensive literature review on factors hindering GBT adoption in the region, empirical data were collected through a questionnaire survey of 300 green building experts across Nigeria. The analysis confirmed the significance of 12 challenges affecting GBT implementation in Southwest Nigeria. Key benefits identified include reduced energy costs, improved occupant comfort and productivity, enhanced indoor air quality, and lower maintenance costs. These were ranked as the top four benefits driving the adoption of GBTs. The findings provide valuable insights to help practitioners and policymakers develop effective strategies for promoting GBT adoption, ultimately contributing to the sustainable development of buildings. Future research will explore the economic benefits associated with the adoption of green building technologies in Southwest Nigeria
