Abstract

Addressing concerns over resource scarcity and environmental sustainability necessitates a global shift towards sustainable energy, notably facilitated by adopting Light-Emitting Diode (LED) lamps. This transition is pivotal for ensuring global energy security and aligning with sustainability goals. This study endeavors to comprehensively analyze potential energy savings achievable through the transition from Fluorescent (FL) lamps to LED lamps within industrial offices. Emphasis is placed on highlighting the central role of energy efficiency. Utilizing false color rendering as a visual guide, the study systematically identifies areas where FL lamps inadequately illuminate. The findings prompt recalculations for determining optimal room illumination achievable through implementing LED lamps. Lux calculations are then employed to showcase the superior illumination offered by LED lamps, revealing consistent monthly cost savings of 35%, particularly when harmonized with Building Management System (BMS) control in industrial office buildings. The study's results indicate that LED lamps provide superior illumination, yielding a noteworthy 35% monthly cost savings, especially when integrated with BMS control. Lamps contribute modestly (21-30%) to overall energy consumption, while air conditioning commands a substantial 60%, underscoring the critical need for advanced lighting technology. This need is emphasized, particularly with Solar PV as a sustainable energy source. Understanding technological developments, especially in BMS, is crucial to optimize energy efficiency in industrial offices. The imperative implementation of LED lighting technology is a critical solution to address resource scarcity and environmental concerns in industrial offices. The efficacy of LED lamps in achieving significant energy savings, especially when coupled with advanced systems like BMS and complemented by renewable energy sources such as Solar PV. The conclusion stresses the significance of staying abreast of technological advancements to foster sustained progress towards energy-efficient and environmentally conscious practices within industrial environments.

Abstract

Geothermal drilling operations in remote areas are commonly powered by diesel generators, leading to high fuel consumption and substantial carbon emissions. This study explores the integration of a hybrid solar PV–diesel generator system to enhance energy sustainability at a geothermal drilling base camp in Indonesia. The system design considers local renewable energy potential and incorporates integration with existing equipment. The integration strategy is evaluated through a feasibility analysis considering system efficiency, energy yield, and environmental impact. Using Helioscope software for solar simulation and load analysis based on equipment specifications, the results show that the PV system can supply up to 35% of the daytime energy demand, reducing daily carbon emissions by 8% and enhancing generator performance through optimized load sharing. Despite the absence of battery storage, the system demonstrates significant environmental and operational benefits, while also highlighting the potential for further improvements through energy storage integration, smart control systems, and targeted energy management.
