The hasty changes in the curricula that have occurred in recent years in the School of Architecture of XXX have generated some problems in the subject of Descriptive Geometry that have been added to others that had been ongoing for many years. A Teaching Innovation Project (TIP) seeks to provide a solution to the problems raised with new methods of teaching inside and outside the classroom and greater interaction between the students and the professor. This way, geometry is no longer something abstract, unrelated to the professional practice of the architect. Thereby, it is intended to structure a new subject that provides students not only with graphic and spatial techniques but also with teamwork, cooperation, training, sufficiency and autonomy resources that help them in the development of their future career. In order to carry out this new methodology for teaching, a course based on gamification has been designed, which allows the students to focus on the subject from a more playful point of view with the aim of motivating and involving them. Based on a three-year experience of comparative work between the traditional and the proposed systems, the conclusions obtained with regards to the withdrawal rate, academic performance and perception of the teaching method are presented in this paper. The incorporation of techniques based on games had a motivating effect on the students, who discovered a way of learning by playing what they previously perceived as a tedious subject.

The following contribution focuses on the low-cost Shining 3D EinScan-Pro scanner, above all the analysis of its precision and accuracy. The need to prove the functioning of this instrumentation in practical cases (the sculptures by Eduardo Chillida preserved in the Chillida-Leku Museum and along with some artefacts collected in the Archaeological Museum of Sarno), has led to the comparison and validation of the instrument through a methodology necessarily diversified from the guideline VDI/VDE 2634, part 2 and part 3, characteristics to the test the optical 3D measuring systems with planar measurement, which works according to the triangulation principle. In particular, two types of comparisons were made: geometric-formal and metric-dimensional. The first type of analysis was carried out analysing the geometric parameters of the models, suitable for validating the information: dimensional (difference between some main measurements); superficial (total mesh extension) and of the form (that is, the discrepancies returned through a DEM analysis). The second type of analysis, instead, of the metric type, was carried out. The complete results of the various analyses will be presented and critically discussed within this contribution in order to prove the stability and the metric quality of this hand-held EinScan-Pro, following the comparison with medium-high end systems now well established in the field of cultural heritage survey.

The project that we present develops a mobile application (ArtAlive®) for the generation of augmented reality experiences on museum sculptural objects. The novelty of our application is that we eliminate the markers that other applications need to run. We do this turning the sculptures into their own markers, based on the recognition of anamorphic images of these sculptures: two-dimensional images of three-dimensional objects. So we eliminate the intermediate elements of the process making the experience easier. The aim is to transform the experience of visiting a museum into a more interactive and intuitive experience. The possibility of accessing the information contained in the augmented reality experiences linked specifically to each work, from the comfort of the smartphone, gives the process greater accessibility and flexibility. The recognition of the objects is developed with Vuforia, an augmented reality software development kit (SDK) for mobile devices. ArtAlive® has been registered in the Spanish Intellectual Property Registry, and a possible business model has been defined in a very basic way.

Indoor air quality in buildings must be guaranteed for the health and comfort of the occupants. In order to assess the ventilation strategy of a considered room, the parameter of the air change efficiency ( ${\epsilon }^a$ ) can be used. The objective of this work is to provide designers with a graphical tool for a reliable estimate of the value of ${\epsilon }^a$ of a room. The temperature gradient between the outdoor air supply and the indoor air is so low that the ventilation flow can be assumed as isothermal when high-efficiency heat recovery systems are used. By means of charts, the optimal location of the openings for a better ${\epsilon }^a$ can be determined during the design process, in order to subsequently apply them. It is concluded that it is very important to consider the ${\epsilon }^a$ in the case of openings located in facing walls given that its range varies between 40% and 65%. In contrast, its use can be obviated in the case of openings located in non-facing walls, as the value of ${\epsilon }^a$ obtained is close to 50%; this means a perfect mixing air flow pattern, which is the reference value for the estimation of the indoor air quality (IAQ) in the different national regulations.

Los continuos avances en los últimos años de equipos de levantamiento tridimensional han aumentado el abanico de posibilidades para el registro, documentación y difusión del patrimonio. Pero, y desde esta hipótesis partimos, aún existen obstáculos para la creación de modelos 3D fotorrealísticos y fidedignos en algunos ámbitos geométricos y radiométricos. Estos aparecen cuando las características de las piezas son adversas para su digitalización, es decir, la geometría del objeto carece de aristas definidas y/o su acabado no permite su registro, bien por su color, uniformidad, reflectancia, etc. Este estudio plantea y presenta resultados de un modelo fotorrealístico aplicado al levantamiento de una escultura de Jorge Oteiza. Obra caracterizada por una geometría y textura desfavorables a las ideales para su digitalización. La solución planteada pasa por una metodología fundamentada en la combinación de técnicas: modelos capturados mediante escáner óptico de triangulación Artec con el apoyo del software fotogramétrico PhotoScan en la fase de texturización.
