Evaluasi Aspek Penghawaan Alami Terkait Sistem Ventilasi Bangunan Berdasarkan Standar Nasional Indonesia (SNI)

Abstract

Semarang is an area in Indonesia with a tropical climate and the potential for relatively high wind speeds. Utilizing natural potential is one effort to increase indoor thermal comfort. This condition has yet to be exploited, especially in buildings in Semarang, one of which is the Semarang City Regional Disaster Management Agency Office, which is still dominated by artificial ventilation systems in the form of air conditioning. This research aims to determine the distribution of air circulation within the Semarang BPBD space and then provide recommendations for range design to meet the standards set by SNI 03-6572-2001. The research methods used are descriptive, quantitative analysis methods and simulations. The descriptive method is a research method that examines problems obtained from observation data to obtain physical and non-physical data on buildings. Quantitative analysis methods are used to calculate the size of the lighting on the facade by comparing it with the Indonesian National Standard (SNI) 03-6572-2001. The simulation method is used to process data and analyze results obtained using Revit 2022 software for building modeling and Autodesk CFD 2024 to determine air distribution in buildings. This research shows that the air distribution and width of building openings do not meet SNI 03-6572-2001 standards. It is hoped that the office design recommendations can serve as guidelines for using natural systems as the primary ventilation in buildings.
