The wooden Shenashil is among the most characteristic elements of the vernacular architecture of southern Iran, and of Bushehr in particular. Its semi-transparent wooden lattice simultaneously moderates solar radiation, admits the sea breeze and preserves visual privacy. Its transfer to Shahr-e Kord, however, cannot be direct. At an altitude of 2,070 meters, with a daily mean of approximately -2.1 °C in January and mean daily minima below zero for five consecutive months, the climatic requirement is inverted: the radiation that must be excluded in the south must be admitted in the highlands. The present study therefore examines whether the Shenashil can perform effectively in such a context, and through which modified parameters. A descriptive-analytical and comparative method is adopted, drawing on long-term meteorological records for both cities and on Kasmaei’s analytical framework in Climate and Architecture. The findings indicate that visual control and privacy are transferable with minimal modification, whereas the ventilation mechanism, the shading pattern and the selection of materials require redesign. Accordingly, a theoretical model designated the Cold Shenashil is proposed, comprising a fixed horizontal overhang, a lattice of reduced density (thirty to forty per cent), a ventilated cavity of sixty to seventy centimeters, dual-mode openings and a low-emissivity inner glazing, with frost-resistant timber substituted for the traditional wood. The physical principles involved are those of the Trombe wall and the attached sunspace, expressed here in a vernacular architectural vocabulary. The model is therefore presented as an identity-bearing alternative alongside these systems rather than as a replacement for them. Numerical validation through CFD and energy simulation, together with a pilot implementation, constitutes the necessary next stage.
