“…Lamp efficacy of 74 and 80 lumen/W could be achieved with T5 fluorescent tubes, and 104 lumen/W with high power LEDs (light-emitting diodes). It should be pointed out that the T5 fluorescent tube is relatively well established and inexpensive, whereas the cost, the control and cooling of a single-lamp high power LED lighting product could be a challenge [46,55]. It can be seen that lowering the LLD would have huge energy saving and hence mitigation potential.…”

“…[19] Iluminación: la evolución reciente ha sido vertiginosa, la eficiencia pasó del 10 % en lámparas incandescentes al 95% en lámparas LED; logros semejantes se relatan en la durabilidad de los componentes. Pero esta tecnología trae problemas ambientales asociados al desecho de las lámparas usadas: la presencia de elementos tóxicos en el sistema demanda el desarrollo de métodos de reciclaje y deposición final, nuevo reto para la ingeniería.…”

ResumenEste artículo de reflexión sustenta que el conocimiento sobre materiales y su procesamiento son factores clave del desarrollo tecnológico e industrial. Se muestra la relación entre la dinámica de la innovación y la tecnología de materiales, evidenciada en las revoluciones industriales de los últimos siglos. Igualmente se plantea el reto que enfrenta el área del conocimiento en materiales ante la escasez de materia prima y la disminución del impacto ambiental derivado de la transformación y la deposición final. Esto ha generado la necesidad de fortalecer la formación científica y profesional en materiales para respaldar los sistemas productivos nacionales y generar valor agregado. Se presenta como evidencia la importancia estratégica de los materiales en diferentes países para el desarrollo tecnológico. Finalmente el fuerte incremento de programas de postgrado en el área de materiales en Colombia se discute frente al reducido número de programas de pregrado en Ingeniería de materiales.

“…As the buildings account for about 40% of total final energy consumption (and its amount has been increasing at a rate 0.5-5 % per annum in developed countries [1]), the efficient building climate control can significantly contribute to reduction of the power consumption as well as the greenhouse gas emissions. Energy savings with minimal additional cost can be achieved by improvement of building automation system (BAS), which can nowadays control both heating, ventilation and air conditioning (HVAC) systems and the blind positioning and lighting systems [2], [3].…”

Predictive control in buildings has undergone an intensive research in the past years. Model identification plays a central role in a predictive control approach. This paper presents a comprehensive study of modeling of a large multizone office building. Many of the common methods used for modeling of the buildings, such as a detailed modeling of the physical properties, RC modeling, etc., appeared to be unfeasible because of the complexity of the problem. Moreover, most of the research papers dealing with this topic presents identification (and control) of either a single-zone building, or a single building sub-system. On contrary, we proposed a novel approach combining a detailed modeling by a buildingdesign software with a black-box subspace identification. The uniqueness of the presented approach is not only in the size of the problem, but also in the way of getting the model and interconnecting several computational and simulation tools.
