Through this project, the students learned about various building service systems like mechanical ventilation, air conditioning, fire protection, and vertical transportation in Summit USJ Mall. Regular maintenance of components is important to ensure all systems are functional and increases their lifespan. It is also crucial for architects and engineers to understand and apply building regulation standards like UBBL 1984 which aim to standardize regulations and ensure user safety. In conclusion, developing a basic knowledge of different building service aspects is important, and studying the building services of Summit Mall provided valuable hands-on experience and in-depth understanding.
