Electrical installation design for low voltage system (office building with seven floors)
Abstract
This Final Year Project demonstrated the design of electrical installation system for
a commercial building. An office with seven floors has been selected for this project. The
electrical installation system included lighting system and the power distribution system. This project included the design of lighting layout, power socket layout, circuiting of the lighting point and power point, lighting switching, cable sizing, protective device,schematic diagram and also design the power factor correction board. Those electrical installations were designed with the AutoCAD software. The design of lighting layout was depending on the illuminance calculation while the power point layout was based on the position of machine or furniture layout of the building. The illuminance calculation and the load calculation were determined by following the standard and regulations of IEE Wiring Regulation Edition 17th, IES lighting handbook and JKR standard and regulation. As a result, the electrical installation system for the building was successful designed with costsaving and well energy management.
