“…DIALux is one of the most commonly used tools in the simulation of lighting systems [1], [4], [6], [8], [11]- [15]. In this sense, this research demonstrates that the results of the simulation in DIALux are very similar to those of field measurements, confirming what was reported in previous studies [11], [15].…”

“…Despite the wide coverage of academic studies regarding indoor lighting, only a few studies have particularized in the analysis of underground parkings [8]. In this context, this paper proposes a strategy of energy saving for an underground parking that involves the replacement of a traditional lighting system based on fluorescent technology for a more energetically efficient and safe one to the users.…”

This research aims to identify the most suitable lighting system for an underground parking in an academic building according to international standards. Nine lighting systems scenarios were evaluated and the most suitable was selected considering experts criteria through an Analytical Hierarchical Process (AHP). The decision criteria considered were: total power, average lifespan, life-cycle cost, illuminance, uniformity, glare, energy efficiency, color rendering and energy saving, some of which were simulated through DIALux software. Among these criteria, the uniformity of the illuminance was the most influential criterion in the final decision according to experts' judgement. Contrariwise, glare and color rendering were the least important criteria. As a result, a LED technology lighting system with an expected annual energy saving of 35% turned out the most suitable for the indoor facility under study.

“…The technical validity of the improvement proposal was obtained by modeling and simulating all the building's facilities in the free software DIALux, which is one of the most commonly used tools in lighting systems simulation [1,4,5,9,10,[18][19][20][21]. In this regard, this research demonstrates that the results of the simulation in DIALux are very similar to those on-site a In the case of the auditoriums, an average use of 2h per day was considered, and for the theater 8h per month, wich is equivalent to 0.3h per day.…”

“…Another important element to highlight is that the studies that have validated the implementation of indoor LED lighting systems as the best strategy against traditional lighting technologies [1,4,5,9,18], do not consider the costs of the final disposal of a massive FL replacement. Fluorescent and compact fluorescent lamps contain Mercury, a potentially dangerous element for the environment, so the final disposal of these lamps must be handled carefully through special recycling techniques [2,3].…”

“…In recent years, several studies have considered the implementation of LED lighting (Light-Emitting Diodes) to reduce the electricity consumption of the facilities and thus contribute to the energy efficiency in buildings [1,4,5,9,10]. LED lighting has gained special relevance in recent years over traditional lighting technologies due to its high efficiency, long ASTESJ ISSN: 2415-6698 lifespan and low maintenance cost.…”

Since lighting constitutes an important part of the total electricity consumption of a country, the design and implementation of more efficient interior lighting systems are one of the feasible strategies to reduce energy consumption. With this purpose, in recent years several studies have considered the use of LED lighting systems. However, its implementation at a large scale is still unaffordable for some organizations like academic institutions. In this context, this research presents a strategy to replace the current fluorescent-based lighting system to LED technology in a building of a higher education institution in Ecuador, and thus contribute to reducing energy consumption in campus facilities. The appropriate LED lamp alternative was selected from those available in the Ecuadorian market through AHP multicriteria decision-making method. The improvement proposal included an annual schedule for the progressive replacement of fluorescent lamps, based on the economic savings that would be generated every year after its implementation. The proposal was technically validated by simulation in DIAlux 4.12 and its economic feasibility was demonstrated by estimating the net present value and the equivalent uniform annual cost. With this strategy, a total of 2595 fluorescent tubes installed in the 215 building light points, can be replaced with LED technology in three years, with an initial investment of 4949.10 USD and generate an energy saving of 47.36%.
