Determinación de la calidad del aire con la inclusión de vegetación en ambientes interiores de espacios educativos, y su inclusión arquitectónica
(2019-05-21) Mena Campos, Juan David; Quesada Molina, Juan Felipe
The present degree work aim to find an ecological alternative, through the inclusion of indoor planting as inner gardens, to promote a system of air renovation and purification inside the educative spaces, places where the agglomeration and use ability, causes precariousness of the optimal environmental conditions for the development of the activities required in these spaces. By implementing vegetation, it is expected to reduce the amount of polluting gases (taking as reference the indoor carbon dioxide for this research), and also, to balance the interior temperature to avoid the use of air renewal by external infiltration. For its effect, a case study is implemented within the Faculty of Architecture of the University of Cuenca, where during periods of equal time and occupation, a typical classroom is controlled in two different conditions of equipment, that is, a before and after the inclusion of vegetation, each stage consisting of one week. The space is controlled by portable climatic stations, with terminals for the measurement of temperature, humidity and particles per million carbon dioxide. After a quantitative and qualitative analysis, it is possible to observe that by including the proposed vegetation, the concentration of pollutant inside the space is reduced, in turn, reducing the interior temperature, seeing as the only counterproductive result the increase of the interior humidity, being an important factor in the perception of conformity of the users of the experimental classroom.

Objective To estimate electric self-sufficiency through added or integrated photovoltaics (PV) on roofs jointly with heritage and architectural implications analysis. Discussing the impact associated with achieving energy democratization, observing consequences of typical PV technology with crystalline solar cells products, more efficient, mature and economical, compared to new "architectural" PV products developed for mimicry, less efficient, costly, and involving to remove the authentic original coating tiles. Methodology Through three-dimensional BIM roof diagrams, the overall solar potential is estimated, and this with respect to own demands. Self-generation margins are projected with locally validated PV production models. Then, through photomontages the relative impact of cristalline PV solar products as well PV tiles, observing the relative impact from different urban perspectives. Conclusions PV crystalline solar panels superimposed on roofs could reach electrical surpluses, between four and twenty times. PV roof tiles also would cover a very high demand with substantial surpluses, between two and nine times. From an architectural perspective, it has been shown from urban perspectives, crystalline solar panels are not being noticeable when buildings have more than two floors, but in one floor buildings or from distant and aerial perspectives the impact is significant. From street point of view and urban scale, PV roof tiles, despite having been created for mimicry, also have an effect on one floor buildings, specially in near sight view. Originality The originality of this work lies besides estimating the urban solar potential widely analysed in the literature, to counterpose conservation and authenticity aspects, against renewable energy integration consequences. These aspects have not been analysed jointly in the literature so far we know.
