We present a detailed study of heating and cooling processes in LED luminaires with passive heat sinks. Our analysis is supported by numerical simulations as well as experimental measurements, carried on commercial systems used for outdoor lighting. We have focused our analysis on the common case of a single LED source in thermal contact with an aluminum passive heat sink, obtaining an excellent agreement with experimental measurements and the numerical simulations performed. Our results can be easily expanded, without loss of generality, to similar systems.

Original scientific paper https://doi.org/10.2298/TSCI190525077M Smart control systems and new technologies are necessary to reduce the energy consumption in buildings while achieving thermal comfort. In this work, we monitor the thermal evolution inside a scale reduced closed space whose exterior and/ or interior wall faces have been painted with a coating solution. Based on the experimental data obtained under different environmental conditions, a simulator was developed and tuned to reproduce the thermodynamic behavior inside the spaces, with a relative error of less than 3.5%. This simulator lets us also estimate energy savings, temperature, and flux behavior under other conditions.

There are numerous passive strategies for reducing energy consumption in Spanish traditional vernacular architecture, depending on external conditions and also on the intended use of the interior of these constructions. In the case study analyzed, localized in an interior area of Spain, known as La Mancha, a set of vernacular buildings have been studied. Solar protection and solar gain, for example, are the key resources related to solar control. While cross ventilation, self-ventilation, or induced ventilation are related to the energy efficiency of the airflow. Other mechanisms identified are, for example, thermal insulation and thermal inertia of the materials. All these K-factors have been checked and parameterized in order to understand these vernacular strategies. Finally, thanks to a comparison of such resources, the study achieved a set of criteria for the use of these solutions in contemporary local architecture.

Autonomous learning is a reality, which is being supported in different technologies and spread out in all areas of knowledge with a wide and accessible repertory of good practices. This paper presents a project focussed in gathering hands-on learning, exploring and producing representations of some relevant architecture sites using new technologies.The set of models designed propose the user a learning by doing approach, to create shapes producing simple elements, which allows informal learning about these buildings. Using and blending technologies available nowadays it is possible to create different models that, not only can be build and touched, but also convey a range of spatial concepts, proportions and wayfinding information.Building your own prototypes maintain high level of interest, incorporate tangible interactions encouraging learners in the content.We undertook our first formative module designing initial prototypes experimenting with different methods and technologies that could stimulate creative purposes. The idea is to define some space equivalents in terms of landscape, sections and blueprints to make understandable the main features of the building, while the different supports or stimuli are developed. In order to give more chance to an informal and autonomous learning model, these files will be available on line to be used with laser cutting machines to produce tactile pictures and pop ups, and 3D printers to get volumes and moving parts. We will bring these prototypes to schools and other different potential groups of users in educational and interpretation contexts.
