Designing the Imaginaries Workshop Protocol: Toward Building Envelope and Water Resilience in Indramayu - Indonesia Living Lab

Abstract
Coastal settlements in tropical regions increasingly live with flooding as a recurring condition rather than a rare event. In Indramayu, Indonesia, daily tidal flooding and seasonal river floods contribute to persistent dampness, material decay, sanitation disruption, and reduced indoor comfort. Although technical modelling can describe flood exposure and heat–air–moisture risks, there is still a practical gap in the literature on how to translate such evidence into community-driven, comparable adaptation pathways that can be reviewed, monitored, and improved over time. This paper addresses that gap by presenting a reproducible Imaginaries Workshop Protocol developed for a living-lab setting. The protocol links three elements: (1) technical risk mapping (flood exposure patterns, moisture persistence, and envelope vulnerability), (2) community imaginaries (facilitated storytelling and spatial mapping of lived impacts, thresholds of acceptability, and preferred futures), and (3) response synthesis (bundling measures across envelope, building, and settlement scales into a small set of scenario hypotheses). The protocol also specifies how scenarios are paired with a concise indicator set suitable for later evaluation, including use in visual dashboards for stakeholder feedback. The main contribution is methodological, which is a transparent step-by-step process that supports replication and adaptation in other chronically flooded coastal settlements. While the scenarios reported in this paper remain conceptual at this preparatory stage, the protocol provides a clear pathway for turning mixed technical and local knowledge into actionable, monitorable response options for climate-resilient built environments.
