Vernacular architecture often utilizes locally sourced materials and construction practices honed over centuries. This approach raises questions about its potential relevance for contemporary design challenges. The prevalence of high-rise developments globally, often relying on sealed envelopes and mechanical climate control, contrasts with historical architectural practices. Traditionally, regional architectures emerged from local communities, fostering distinct cultural identities and integrating passive systems for ventilation, cooling, and heating, often utilizing natural elements. The Hanok, traditional Korean houses, serve as a case study. Beyond their current role in tourism, they are also an example of how vernacular knowledge can provide passive climate-response strategies that align with the current principles of creating environmentally friendly buildings.
