Lighting and power distribution systems are fundamental to the functionality, safety, and sustainability of any building. Lighting enhances the usability and comfort of spaces by providing the necessary illumination levels for occupants to perform tasks efficiently and safely. It also contributes significantly to the aesthetic and psychological aspects of interior environments. Proper lighting design supports energy efficiency, aligns with human circadian rhythms, and complies with illumination standards such as those set by CIBSE, IESNA, and IEC 60598.

Power distribution, on the other hand, ensures the reliable and safe delivery of electrical energy from the main source to various end-use equipment and systems throughout a facility. It plays a vital role in maintaining uninterrupted operation of essential services such as HVAC systems, elevators, security, data networks, and life safety systems. The layout and design of the power distribution network, including switchgear, panels, and protective devices, directly affect the system’s resilience, maintainability, and efficiency.

Together, lighting and power distribution form the backbone of building services, and their integration must be addressed early in the design process to coordinate with architectural, structural, and mechanical systems. Their careful planning and implementation are critical to meeting performance objectives, user needs, and regulatory compliance in modern construction projects.
