Comparative analysis of running costs: conventional vs. sustainable industrial buildings during economic crises in Sri Lanka

Abstract

This research study compares and analyses the running costs between sustainable and conventional construction in the context of economic crises. The research methodology adopts a case study strategy with a mono-method approach, utilising document review as the data collection technique. Three sustainable-themed apparel manufacturing factory buildings and three conventional-type apparel manufacturing factories owned by leading brands in Sri Lanka were selected as case studies. Annual energy consumption reports, annual solar production reports, building maintenance schedules, and other relevant documents were reviewed and analysed. The findings reveal that during the pre and posteconomic crisis periods, the running costs of sustainable construction increased by 60% less compared to conventional construction. The implications of this research inform decisionmaking, investment strategies, and policy development, highlighting the economic benefits associated with adopting sustainable construction practices. Further research is recommended to explore specific strategies and technologies contributing to lower running costs in sustainable construction and examine the long-term financial resilience of the apparel manufacturing industry and other sectors. In summary, this research underscores the economic advantage of sustainable construction in reducing running costs and fostering a sustainable future in the construction industry.
