1. Problem Statement

The global transition to the fifth industrial revolution (Industry 5.0) necessitates a re-evaluation of industrial space architecture. Productive architecture, by aligning spatial design with production processes, enhancing workplace quality, and leveraging smart technologies, can significantly boost the productivity of heavy industries. However, many of Iran’s heavy industrial complexes still grapple with challenges such as physical obsolescence, spatial structure misalignment with production systems, and poor adaptability to technological advancements.

2. Research Objectives

This paper aims to propose an architectural design model for productive spaces tailored to the requirements of Industry 5.0.

3. Research Methodology

This study employed a qualitative approach utilizing a two-round Delphi technique. In the first round, initial indicators were extracted through a systematic literature review, and a proposed theoretical framework was developed. In the second round, the perspectives of 23 experts in industrial architecture and productivity were gathered and evaluated over two stages, with indicators finalized based on an 80% consensus criterion.

4. Conclusion

The findings led to the identification of 19 key indicators across three main axes: (1) space ownership and operational models, (2) technical, technological, and energy considerations, and (3) spatial planning and functional organization. Consequently, a conceptual model for the productive architecture of Iran’s heavy industries within the context of Industry 5.0 was defined. The results of this research can serve as a foundation for designing and regenerating the country’s industrial spaces, contributing to enhanced productivity, sustainability, and improved workplace quality in heavy industries.
