Life cycle assessment applied to facility management of exposed steel frames – case study

Abstract

Purpose

Facility management (FM) plays an important role in the attainment of a sustainable built environment during the building operational stage since it is responsible for decisions that influence materials’ durability, waste, cost reduction and energy efficiency. However, the integration of the life cycle assessment (LCA) approach in FM presents some difficulties in obtaining complete inventories for building components, tracking material flows and defining system boundaries. This paper aims to establish the environmental impact comparison between maintenance actions and replacement interventions performed during the life cycle of a steel frame from a building facade.

Design/methodology/approach

For this purpose, the effects of different repair/maintenance actions and end-of-life scenarios were analysed using two tools: an LCA building information modelling-based tool and an LCA open-source tool.

Findings

The results showed that repairing and maintaining the steel structure is essential for the safety and preservation of the steel structure. However, steel maintenance and repair practices that involve fewer environmental impacts need to be explored.

Social implications

It also emphasises the crucial role of facility managers in promoting sustainability and supporting informed decision-making throughout the building’s life cycle, thereby aiding in the pursuit of sustainable development and the goal of decarbonisation by 2050.

Originality/value

This study reveals that maintenance processes in building management have a greater environmental impact compared to material replacement activities, especially concerning the steel structure within the case study building, as assessed using two LCA software tools. The findings provide valuable insights into the environmental impacts of maintenance and replacement phases and underscore the need for further investigation into more sustainable maintenance practices within facility management. Additionally, the study raises public awareness and engagement in environmental responsibility, contributing positively to the achievement of a sustainable built environment.
