“…Kemajuan teknologi lampu penerangan hemat energi telah menghasilkan banyak jenis lampu baru untuk penerangan jalan. Teknologi penerangan yang paling menjanjikan untuk penerangan jalan raya sebagai pengganti sistem pencahayaan sodium tekanan tinggi (high pressure sodium) saat ini antara lain lampu LED (light emitting diode), induksi, plasma, dan sistem pencahayaan metal halide (MH) [7]. Di antara jenisjenis lampu penerangan tersebut, Lampu LED paling populer karena memiliki luminous efficacy 70-160 Lm/Watt, life time 40.000-90.000 Jam, kuat pencahayaan yang seragam, mengurangi silau dan meningkatkan kenyamanan mata dan kemampuan diskriminasi visual pengemudi kendaraan [8].…”

Pada tahun 2017, Lampu Penerangan Jalan Umum (LPJU) di seluruh Indonesia telah berjumlah 225.249 unit, yang sebagian besar masih menggunakan lampu penerangan berteknologi lama dan tidak efisien sehingga mengonsumsi energi listrik yang sangat besar yakni 3.503,47 GWh/tahun. Untuk itu sangat mendesak diperlukan usaha penghematan energi listrik di sektor LPJU. Guna mendukung upaya ini maka dalam penelitian ini dilakukan analisis teknis dan ekonomis untuk menguji kelayakan proyek retrofit/ penggantian LPJU di Jalan Raya Gatot Subroto Denpasar dari Lampu Merkuri 250 W menjadi Lampu LED 93 W. Pada akhir studi diperoleh bahwa proyek retrofit ini layak secara teknis karena mampu menghasilkan kuat pencahayaan rata-rata 13 Lux (dibandingkan syarat SNI lebih dari 11 Lux) dan penghematan konsumsi energi listrik 157,65 MWh/tahun serta layak secara ekonomis karena memenuhi kriteria kelayakan investasi Net Present Value (NPV), Profitability Index (PI) dan Discounted Payback Period (DPP).

“…The common example is replacing high pressure sodium fixtures with LED, plasma or induction ones (the last two also belong to gas discharge sources) [1] and involving various hardware modules (e.g., occupancy sensors) enabling lighting control [2]. The main problems being analyzed in the related research were reducing energy consumption, improving illumination quality [3], optimizing investment and maintenance costs [4].…”

Roadway Lighting Retrofit: Environmental and Economic Impact of Greenhouse Gases Footprint Reduction

2018

View full text Add to dashboard Cite

Roadway lighting retrofit is a process continuously developed in urban environments due to both installation aging and technical upgrades. The spectacular example is replacing the high intensity discharge (HID) lamps, usually high pressure sodium (HPS) ones, with the sources based on light-emitting diodes (LED). The main focus in the related research was put on energy efficiency of installations and corresponding financial benefits. In this work, we extend those considerations analyzing how lighting optimization impacts greenhouse gas (GHG) emission reduction and what are the resultant financial benefits expressed in terms of emission allowances prices. Our goal is twofold: (i) obtaining a quantitative assessment of how a GHG footprint depends on a technological scope of modernization of a city HPS-based lighting system; and (ii) showing that the costs of such a modernization can be decreased by up to 10% thanks to a lowered CO 2 emission volume. Moreover, we identify retrofit patterns yielding the most substantial environmental impact.

“…Most of the existing research focuses on the need for adequate control [15] of both daylight [8,16] and occupancy [16,17,18] conditions. A second strategy is to undertake technology retrofits [19,20], in which LED is of increasing interest as it is becoming a more affordable and reliable alternative [21,22], even though it has not always proven to be worth the investment [23,24]. Research into the lighting efficiency of underground spaces has been scarce until now [2,23].…”

Lighting systems are usually one of the largest electrical end-uses in underground metro stations. Taking into account that budget restrictions in publicly owned companies hinder energy efficiency retrofit projects that require high initial investments, affordable energy saving strategies are needed. This paper presents a low-cost approach for reducing lighting electricity use in underground stations, without affecting passengers' comfort or the metro operator's service. For this purpose, an adaptive lighting strategy of dimming the illuminance levels of artificial light sources has been developed. Dimming controls are based on the occupancy of the station, and the preventive maintenance and cleaning cycles of the luminaires. The stations' monthly occupancy patterns are defined through the k-means clustering technique. To illustrate its effectiveness, the method was applied to 115 underground stations of the Barcelona metro network. The results revealed overall electricity savings of 255.47 MW h on a biannual basis, which represents 36.22% of the stations' baseline lighting consumption. Individual energy savings were found to range from 25 to 87.5 MW h/year in the stations of the Barcelona metro network, depending on the number and profile of station users. The research findings will undoubtedly be useful for the future energy efficiency project plans of worldwide metro operators and managers of other underground spaces.Peer ReviewedPostprint (author's final draft
