Abstract

Energy efficiency in office buildings has become a critical issue due to increasing electricity consumption, particularly in lighting systems that operate continuously. Inefficient lighting design can lead to excessive energy use, higher operational costs, and reduced sustainability performance in commercial buildings. Objective: This study aims to analyze the implementation of Light Emitting Diode (LED) technology to improve energy efficiency in office lighting systems using DIALux simulation, while ensuring compliance with standard illumination requirements. Method: This research employs a quantitative descriptive approach supported by simulation modeling. Data were collected through field observation, illumination measurement using a lux meter, and documentation of room specifications. The analysis was conducted using DIALux software to evaluate illuminance levels, light distribution, and energy consumption based on office lighting standards. Findings: The results indicate that the LED lighting system achieves an average illuminance of 340 lux, which meets the SNI 6197:2011 standard (300–500 lux), with a uniformity ratio of 0.68 indicating adequate light distribution and visual comfort. The system consumes 36 kWh per month, which is more than 50% lower than conventional fluorescent (TL) lighting systems. Implications: The findings suggest that LED lighting systems can provide efficient and compliant lighting solutions while significantly reducing energy consumption and operational costs. This supports the implementation of energy-efficient and sustainable building practices. Originality: The originality of this study lies in its integrated approach that combines room characteristics, LED configuration, and DIALux simulation to evaluate lighting performance and energy efficiency simultaneously, offering a practical framework for office lighting design.

Abstract

Electrical installation systems in healthcare facilities must ensure safety, reliability, and operational continuity because medical services depend on stable power supply and adequate lighting conditions. In polyclinic environments, electrical disturbances may affect service quality and patient safety, making proper system design essential. Objective: This study aims to design and evaluate the electrical installation of the Cibubur Hospital Polyclinic based on national standards, focusing on load distribution, lighting performance, backup power systems, and grounding effectiveness. Method: This research employs a mixed qualitative–quantitative descriptive approach. Data were collected through field observations, direct measurements using electrical instruments (clamp meter, lux meter, and earth tester), and documentation review of installation layouts and technical standards. The analysis was conducted through technical calculations and standard-based evaluation. Results: The total electrical load is divided into 11,883 W for normal PLN load and 7,406 W for priority UPS load, indicating a functional separation between general and critical services. Lighting measurements show that seven out of ten rooms meet the required standards, while three rooms remain below the threshold. The grounding system demonstrates resistance values well below the allowable limit, indicating effective protection performance. Implications: The results indicate that integrated electrical installation design can support safe and continuous healthcare operations, although improvements in lighting uniformity and system specification consistency are still required. Originality: This study offers an integrated evaluation of load distribution, lighting, backup power, and grounding within a single polyclinic case study, providing practical and academic contributions to electrical system design in healthcare facilities.
