The heating, cooling, ventilation, and fire protection systems of the trade center were installed by our company. The retail stores were air-conditioned using fan coil systems. Exhaust, fresh air, heating, cooling, and fire protection systems were installed within the stores. Hood exhaust ventilation systems were provided for the fast-food areas. A complete fire protection system, including sprinklers and fire hose cabinets, was installed throughout the entire trade center. The project was completed within 6 months.
