Resumen
This dissertation is a 100k to validate the concept of Atria- Sunspace, based pnncipally in their relationship and how both can improve the environmental performance of a building, reducing it energy loads. Therefore this dissertation seeks to know how both concepts, Atria and Sunspace, become in one, and the advantages that bring them to the buildings. Besides the concept of sustainability it was brought to the system of Atria-Sunspace. The research involves the development of the dissertation in two main points. First, based in create a background with the general concepts and factors that influence in Atria-Sunspace performance. Second, generate the expenmentation stage to know the behaviour of it under fixed parameters. The concepts of Atna and Sunspace has been developed along the history mainly separately, but it was not taking in account that are closely related, due to both works with the same parameters and also both try to achieve the comfort to the built environment. Exist different typologies for Atna and Sunspace, but it was concluded that making and unifying these both systems it would be accomplished better results if they work separately. Once linked the concepts, in an Atria-Sunspace, it was presented the component and factors that influence in their performance, also given a qualitative appraisal of how it would work for critical season as winter and summer; therefore it was conduded that Atria-Sunspace achieve better performance when it was related with it shape and with the materials that compound it, also considering the dimatic conditions. To know how the atria- sunspace performs, it was carried out experimentation to the Atria-Sunspace, carrying out 3 generic modeis, with different glaze transmittance; in a way to know the ¡mprovement of the buliding. After the simulations it was conduded that the Core Atria-Sunspace using 0.62% of glaze transmittance, aliowing the energy savings for the butiding, achieved the better performance FinaUy, to bring the results obtained for the generic modeis to a real scenario it was carned out the thermal and daylighting performance for a real architectural project, the Pitt River Museum Research Centre (developed by PRS Architects), and then after the results were obtained, to the case study was incorporated the AtriaSunspace that performed better in the generic models, corresponding to the Core Atria-Sunspace with 0.62% of glaze transmittance. This was carned out in a way to know how much improve the heating and cooling demands and also the daylighting conditions.
