Fluorescent Tube

A targeted energy analysis was carried out in a textile industry focusing on lighting system. It is observed from the study that the industry can replace the existing TL-D 36 W/54 fluorescent tube lights with energy efficient TL-5 28 W/865 fluorescent tube lights with electronic ballast. This has resulted in energy saving of 206388 kWh per annum. The corresponding CO2 mitigation is estimated at 167.174 t CO2/annum. An experiment was conducted to identify the exact light intensity of the proposed lighting system. The result shows that the light intensity has reduced by 11.1 % which is insignificant compared to energy saving and CO2 mitigation. The investment for the new lighting fixtures is estimated at INR 0.468 million with cost saving of INR 1.65 million which has return on investment of just 3.3 months.

Light Levels

The continual rising cost of energy, existing outdated lighting technology, and inefficient lighting designs have given property owners the opportunity to improve their facilities by retrofitting their existing luminaires with an energy efficient lighting system. A lighting retrofit uses the existing electrical infrastructure to replace, relocate, or convert existing luminaires with the latest generation of cost-effective components. New lighting technology has emerged within the last 6 years that generates energy savings of 40% to 50% while maintaining existing light levels. These upgraded and field-tested solutions lower energy consumption, generate a healthy financial return on investment, and can improve both the quality and quantity of light in the task area. As with any other solution, a cost-effective lighting system must be designed and engineered carefully to accommodate the needs of each work space. Simply installing a new lamp into an existing luminaire will not necessarily guarantee substantial energy savings or an improved lighting environment. In any space that uses electric lighting, the lighting designer must evaluate potential solutions for energy consumption, maintenance concerns, delivered light levels, hostile environments, and the overall economic impact of installing and long-term operation of the new system. In this paper, the author will discuss energy efficient lighting design criteria and how a lighting designer properly engineers a retrofit project to deliver energy savings without sacrificing light levels. The discussion includes a summary of both traditional and emerging technologies, and the long-term impact on energy consumption, maintenance, return on investment, lighting quality, and delivered light levels.

The use of incandescent bulbs by the majority of building occupants in Nigeria has complemented high cost of electrical energy consumption and this has informed prevalence of different types of energy efficient lighting bulbs. The study, therefore, identified and examined types of lighting bulbs used, assessed the rate of use of energy efficient bulbs in selected residential buildings and examined factors influencing its use. The study was carried out in Ife Central Local Government Area of Osun State, Nigeria. Residential settlements in core wards in the study area were considered and four wards in the core zone of the Local Government were randomly selected from the total of eleven while data collection was done with the use of primary and secondary data techniques. Simple random sampling technique was used to select 5% sample size from the entire population and systematic sampling procedure was further employed by selecting every 10th building in the direction of movement which indicated selection of 123 houses. A total of 123 structured questionnaires were administered on the respondents on issues associated with the use of lighting bulbs. Data collected were analysed by both descriptive and inferential statistical techniques. The study found that 90.53% and 72.63% of the respondents used incandescent and energy saving bulbs respectively; variation existed in the wattages of different brands of energy saving and non-energy saving bulbs used in the selected buildings: A major proportion of the respondents used an average number of 1-5 lighting bulbs in buildings and its spaces therein; while quality and cost-saving benefit, energy saving benefit and durability of bulb influenced the choice of fluorescent tubes, compact fluorescent bulbs and light emitting diodes with a mean score value of 2.20, 2.29 and 2.85 respectively. In view of the need to enhance visual performance and comfort of buildings and its occupants respectively, efforts must be made by government to ensure that consumers awareness and enlightenment be increased on the types of lighting bulbs to procure and there is also need to strengthen mechanisms through the importation and sales of energy efficient bulbs only so as to enhance its cost-saving and environment–related benefits amongst others.

ABSTRAKDalam praktiknya, banyak ruangan yang tidak memiliki ventilasi cahaya sehingga menggunakan sumber cahaya hingga selama 24 jam. Penelitian ini bertujuan untuk merancang sistem yang dapat meminimalkan penggunaan listrik untuk penerangan dengan menggunakan sistem solatube. Solatube akan memberikan sinyal pada dimmer yang mengatur kapasitas cahaya lampu sehingga tidak selalu membutuhkan performa penuh. Berdasarkan hasil pengujian, sistem solatube dapat menghasilkan nilai intensitas cahaya maksimal yang dapat memenuhi standar untuk ruang baca yaitu lebih dari 350 Lux dengan persentase penerangan menjadi hanya 1% - 79%, terutama selama penggunaan beban siang hari. Hal ini menunjukkan bahwa dengan penggunaan solatube penggunaan daya untuk penerangan dapat dikurangi, sehingga meningkatkan penghematan energi dan biaya. Kemudian alat ini dilengkapi dengan data logger yang dapat diakses melalui internet untuk memantau penggunaan listrik secara realtime sehingga dapat dilakukan monitoring dan evaluasi untuk pengembangan selanjutnya.Kata kunci: Sistem Pencahayaan, Solatube, Penghematan Energi, Data Logger. ABSTRACTIn practice, many rooms do not have light ventilation, so they use light sources for up to 24 hours. This study aims to design a sistem that can minimize the use of electricity for lighting using a solatube sistem. Solatube provide a signal to the dimmer that regulates the light capacity of the lamp thus it does not always require full performance. Based on the test results, the solatube sistem can produce a maximum light intensity value that can meet the standards for the reading room, which is more than 350 Lux with the percentage of light being only 1% - 79%, especially during the use of daytime loads. This shows that with solatube lighting sistem, power consumption for lighting can be reduced, thereby increasing energy and cost savings. Furthermore this tool is equipped with a data logger that can be accessed via the internet to monitor realtime electricity usage thus that it can be monitored and evaluated for further developmentKeywords: lighting sistem, solatube, energy saving, data logger.

Background:: In recent years, there has been a high demand for executing digital signal processing and machine learning applications on energy-constrained devices. Squaring is a vital arithmetic operation used in such applications. Hence, improving the energy efficiency of squaring is crucial. Objective:: In this paper, a novel approximation method based on piecewise linear segmentation of the square function is proposed. Methods: Two-segment, four-segment and eight-segment accurate and energy-efficient 32-bit approximate designs for squaring were implemented using this method. The proposed 2-segment approximate squaring hardware showed 12.5% maximum relative error and delivered up to 55.6% energy saving when compared with state-of-the-art approximate multipliers used for squaring. Results: The proposed 4-segment hardware achieved a maximum relative error of 3.13% with up to 46.5% energy saving. Conclusion:: The proposed 8-segment design emerged as the most accurate squaring hardware with a maximum relative error of 0.78%. The comparison also revealed that the 8-segment design is the most efficient design in terms of error-area-delay-power product.
