## 3 Case Study: AURA Project
### Housing Scale--Architectural Concept  
The housing cell was formed based on a set of architectural concepts that arise from the need to respond to a social housing solution in a Latin American context:  
* Dwelling decompaction  
It is understood that the concept of traditional compact housing must be fragmented, thus appearing the transition spaces between the different functional pieces (Figure 9). The relevance of these spaces becomes clear to the extent that they create new uses not foreseen in the home or that they give rise to situations that help promote the functional flexibility of the dwelling. This contributes to the following concept: perfectibility. Figure 8: Decantation process from the collective building to the prototype in the Solar City. * Progressivity and adaptability By understanding, in the social context in which this project is located, the difficulty of a family to completely occupy one of the housing volumes that make up the collective building, a process of progressive occupation of this space is programmed (Figure 10). Once the house is completed, you will have the option to improve/perfect it with the implementation of active air conditioning elements that contribute to maintain an optimal thermal comfort, or others in order to give a better answer to the problems that every family faces. Therefore, the housing is progressively improved over time and the family could increase its \"social status\" without being forced to move. * Equipped furniture Following the concept of the disintegration of the house, it shapes its different interior spaces based on the layout of the furniture, which will mutate its position and shape depending on the

On the other hand, it will also have the function of providing different services to the house: conditioning installations, solar chimney, electrical installation, etc. (Figure 11).Therefore, a new level of flexibility is provided within the home according to the needs of its inhabitants. * Hallway AURA 1.0 Project introduces a new element to social housing with the aim of providing additional values to the minimum housing module (Figure 12): 1. Ventilation: The \"hallway\" module works as a bioclimatic dumper between homes, which guarantees cross ventilation in the home, taking advantage of the benefits of the city climate, which provides a pleasant breeze every day at sunset. This air movement contributes to increase the feeling of thermal comfort in the house. 2. Lighting: It works as a transition space between the exterior and the interior of the house, obtaining a graduated light from the gallery of collective access to the interior of the house. The \"hallway\" module, provided with openings to the outside, allows the light to be filtered and dimmed, contributing to obtaining quality and comfortable lighting in the interior spaces for the development of the different domestic activities (Figure 13). 3. Noise: This element works as an acoustic damper between adjoining houses. Due to its configuration, this space allows each home to have four exterior facades, which improves the acoustic behavior of each one of them. 4. Health: This is the organ on which the rest of the conditioning strategies are based, contributing, on the one hand, to the physical health of the inhabitant by achieving optimum hygrothermal and lighting values; and on the other, to mental health, integrating \"the street\", urbanity and territory inside the home. We are facing a society very used to interacting with the environment, so that suppressing this component of the housing cell would cause a sense of bewilderment of the individual that could lead to pathology.
