Evaluation of sustainable construction sites: a lean, green and well-being integrated approach

Avaliação de canteiros de obras sustentáveis: uma abordagem Lean, Green e Well-being

Abstract:

This paper proposes a performance evaluation model of sustainability for construction sites. This model was developed bringing together the Lean Construction, Green Building and the Well-being concepts addressed through the triple bottom line concept of sustainability. Following the Design Science approach, the model was applied in three construction sites at the city of Fortaleza, northeast of Brazil. Results are presented to validate the performance evaluation model proposed. It can be observed that the model can handle a range of variables both in terms of possible management actions and in terms of their sustainability outcomes. Different from others performance evaluation models, this artefact takes in consideration actions that are theoretically deemed to promote sustainability (according to particular construction phases) and managerial actions that are actually implemented. Finally, graphical displays help to guide how sustainability might improve over time, either evaluating individual sites against their previous records or benchmarking different building projects among different construction companies.
