Abstract

— Café is a retail F&B place for eating and drinking fast food and presenting a relaxed or informal atmosphere. Café, which is a public space where customers spend time, of course, must maintain ventilation in the café to ensure the customer’s thermal comfort. For this reason, paying attention to air circulation in the cafe is essential. The author takes the ice cream cafe in Malang as the case study object in this case study research. This research focuses on ventilation on the first floor of the café. After making observations, it was found that the air circulation in the cafe is not smooth and limited because of the closed space. Despite having two air conditioners running, the restaurant’s atmosphere started to feel limiting as the survey was being conducted. The lack of ventilation in this enclosed room further reduces the café’s thermal comfort. To solve this problem, the author provides a solution for implementing cross-circulation by adding windows to the front and back of the café to maximize air circulation and using an exhaust fan in the café kitchen to maintain air quality. So with this, it can guarantee the thermal comfort of customers at this cafe.
