Abstract
The study aimed to evaluate the benefits of cost efficiency in sustainable building project delivery in Nigeria, specifically in Awka Anambra State. It used primary and secondary data, with 86 questionnaires and only 47 valid responses, percentage rating and relative importance index RII was adopted and used for analysing data. The study found that sustainable cost efficiency could be evaluated early in design through value engineering exercises, with RII=.085 . Poor knowledge and construction methodology were rated as the highest barriers to sustainable building and cost efficiency, with RII=0.85 . Life cycle costing could be a valuable method for achieving cost efficiency in sustainable building projects, with RII=0.81 . Benefits of cost efficiency of sustainable building could be achieved by better integration of all relevant professional from inception, design stage, construction stage and throughout the lifecycle of a project, with RII=0.87 . Further studies are suggested to complement the impact of this study and investigate the challenges to implementation of cost efficiency in sustainable lifecycle costing of building projects.
