| dc.description.abstract | Pasar Prawirotaman and Pasar Legi are compared in terms of the natural
ventilation system such as the size of the opening, position of the opening, and existing
fence in the opening. The building shape and orientation of the building are also
considered in the simulation. Therefore, this paper aims to compare the difference in
thermal performance between the traditional market and the modern market in terms of
layout and ventilation. The method that is used in this paper is quantitative methods for
analyzing and collecting the data with variables such as air temperature, wind velocity,
and humidity inside and outside the markets measured using CFD tools and simulation.
The study demonstrates that variables such as opening size, position, existing fence,
building shape, and orientation impact thermal comfort in both traditional and modern
markets. Prawirotaman Market's larger, fence-free openings enhance wind access,
yielding speeds of 1-7 m/s. In contrast, Legi Market, with smaller fenced openings,
experiences wind speeds of 0-4 m/s. Wind direction, predominantly north in Yogyakarta,
influences comfort, and Prawirotaman's west-facing orientation creates uneven wind
distribution (3.5-7 m/s). Legi Market's direct north-facing structure maintains wind
speeds of 2.5-5 m/s. | en_US |
