“…For instance, while comparing LEDs with traditional lighting systems, Macias et al [12] reported that there was a great energy saving, between 41% and 73% of power consumption, compared with the technology of that period such as HPS lamps. Similarly, Serrano-Tierz [13] concluded that the replacement of metal halide lights by LEDs luminaries resulted in a high energy saving and an increase of the life span of the luminaires. Moreover, the use of LEDs reduces the disposal of toxic elements such as mercury to the environment [14].…”

Nowadays, the evaluation of sustainability is an important aspect in the study of agricultural systems and the number of projects and methods for impact assessment of food production systems is increasing. In this work, we initially carried out a survey to know the status of the artificial lighting establishment in horticultural seedling nurseries in southern Spain. Taking into account the data obtained in the survey, we conducted an experiment with different types of fluorescent lamps (TLD-18, CF, TL5, TLD-56), light-emitting diodes (LEDs) and their combinations along with the novelty white LEDs lamps and XTRASUN LEDs to evaluate their technical parameters and spectral light qualities. In addition, the effectiveness of light irradiance (ELIplant) and the use of irradiance (UI) by cucumber and tomato seedling plants were estimated considering their light absorbance capacity previously analyzed. The results showed that TLD-18 lamps and their combinations, CF and XTRASUN LEDs, had a limited value of energy efficiency (VEEI) ≤ 2. The lamps essayed with the lowest total irradiance were LEDs (B, R, V, W) and the ones with the highest values were TLD58-6 lamps. The effectiveness of light irradiance (ELIplant) and the UI were slightly higher in the case of cucumber than that of the tomato for all essayed lamps. Considering the effectiveness of the light irradiance (ELIplant), TL5-6 lamps showed the highest values. On the other hand, considering the use of irradiance, XTRASUN LEDs on the mode of vegetative growth (VG) showed the highest values.

“…One of the main objectives of Universidad Ean is to reduce electricity consumption, since it is the activity with the highest participation in the generation of emissions (around 77% according to the GHG inventory). Since lighting plays a large role in energy consumption, the university is planning to replace low-efficiency lights with energy-efficient ones, since the new ones can reduce energy consumption by 50 to 85% as estimated in [67,68]. Additionally, Universidad Ean plans to install smart plugs that contribute to optimising the energy consumption of electronic equipment in the Founders Building.…”

Towards Carbon Neutrality in Higher Education Institutions: Case of Two Private Universities in Colombia

et al. 2022

This paper addresses the path followed by two private higher education institutions (HEI) in Colombia towards achieving carbon neutrality. The methodology followed by these universities to achieve a carbon-neutral certification, based on the Greenhouse Gas (GHG) Protocol, is first described. The process of developing the GHG inventory, projected towards the carbon neutrality of these organisations while using the standard ISO 14064:2006, involved a series of steps that were consolidated in three phases: (i) definition of the scope, collection of data and emissions quantification; (ii) analysis of results and mitigation actions; and (iii) verification and compensation strategies. Results for the HEIs are shown in terms of the organisational context, carbon footprint measurement, reduction, verification, and compensation. The case is presented for Universidad Pontificia Bolivariana, a multi-campus university that became the first carbon-neutral university in Latin America in 2017, and Universidad Ean, a single-campus university that became the second carbon-neutral university in Colombia in 2021, as verified by the Colombian Institute of Technical Standards and Certification (ICONTEC). This work shows that universities can play a key role in regional and global agendas with their contribution through the incorporation of sustainability strategies, since HEIs can not only achieve carbon neutrality, but they can help other organisations by delivering graduates who are aware of sustainability and provide specific training towards building a sustainability culture, which is needed for regenerative development.

“…La principal causa es su eficacia luminosa o eficiencia, actualmente superior a los 100 lm/W en dispositivos comerciales y con previsión de alcanzar más de 200 lm/W en los próximos años, lo que favorece el ahorro y la eficiencia energética [Fener15]. En la figura 2.1 se representa la comparación de la eficacia (lm/W) de cuatro tecnologías de iluminación comerciales [Serrano15]: halogenuros metálicos (HM), fluorescencia por inducción, fluorescencia con tubos de 16 mm de diámetro (TL5) y LED.…”

CALIFICACIÓN: EL PRESIDENTE LOS VOCALES EL SECRETARIO V Porque si hay un contrincante al que debes vencer en una carrera de larga distancia, ése no es otro que el tú de ayer. Haruki Murakami VII AgradecimientosHa sido un camino largo, demasiado, con cambio de tema tras los primeros años, con la compatibilización con otros proyectos, con errores en las medidas, con obstáculos para las publicaciones, con desmotivaciones, pero como con todo en la vida, lo importante es alcanzar la meta y aprender por el camino. Así, quiero agradecer de corazón a todas las personas que, de una forma u otra, me han acompañado en este trayecto.A mis padres, por su apoyo continuo, por motivarme en los buenos y en los malos momentos, pero también por decirme lo que piensan aunque no vaya a gustarme. Y a mi hermano por estar ahí y verlo todo tan fácil. XI AbstractOver the last decade, white light emitting diodes (WLED) based luminaries have been exponentially replacing traditional lamps (incandescent, fluorescent), due to their long lifetime and low heat generation, but mainly because of their high energy efficiency. Visible Light Communication (VLC) is based on the dual use of LED lamps for illumination and information transmission, making use of the LED short switching times. Therefore, VLC is viewed as an alternative or complement to the traditional communication systems in home scenarios. Over the last years, many research efforts have been oriented to maximize the transmission rate of VLC systems, especially through the use of high spectral efficiency modulation techniques as OFDM. However, it has not been studied how the use of an LED lamp as a VLC emitter affects its main advantage as lighting technology, which is energy efficiency.In this thesis, it is assumed the following hypothesis: the waveform of the VLC modulation signal influences the energy efficiency of the LED luminaire, and specifically the energy performance of its control element or driver. LED lamp drivers are usually formed by switching power supplies which apply a constant current to the light source. Using a switched waveform modulation signal fits this principle. However, utilizing a continuous waveform modulation signal, as employed in modulation techniques as OFDM, modifies the current nature both in the light source (LED) and the driver, affecting their behaviour.The main goal of this thesis is to analyse how the waveform of the modulation signal affects the energy performance of the VLC driver. For that purpose, the work is divided into three steps: theoretical model; model validation through simulations and experiments; and results achievement. In order to analyse the driver energy efficiency, the quality factor "η", named driver Energy Efficiency Ratio is defined. "η" is the ratio between the power dissipated by the LED and the total dissipated power. At the theoretical model, the efficiency ratio of the VLC driver (and its LED and MOS elements XII individua...
