The Hex Deployable kinetic Facade system April 2019-University of Toronto -ARC381 The primary purpose of the building envelope is to protect inhabitants from the outside environment. Although usually static systems, kinetic facades are designed to respond to many scenarios and perform functions that can assist in reducing a building’s heating or cooling loads. An extensive amount of research exists about kinetic facade concepts, strategies, principles, and criteria. However, interdisciplinary studies for proposing the kinetic facade form is relatively rare. Also, there exists a high demand for facade systems with daily solar geometry variation. Hence, parametric design methodologies that facilitate quick form-finding stands as the most appropriate approach to this field of study. In this studio project, my partner Aazeen Haroon and I aimed to create a kinetic facade system that could be utilized in several different settings. The system is comprised of hexagonal units that can be arranged in a variety of different ways to adapt to different contexts and programs. An individual unit consists of six different panels that flex and unflex to allow light to pass through. The panels are controlled using tension cords that are pulled and released using a stepper motor run through an Arduino microprocessor. The strengths of this system lie in its ability to adapt quickly to changing environments to maximize occupant comfort and minimize heat gains/cooling loads. The system’s quiet design using stepper motors as it’s main mechanical driver allows it to be placed on the inside of windows, which shelters it from the exterior environment, in return increasing durability and life span. Finally, the system’s unique design which utilizes flexible materials that can flex and unflex to create space for incoming light creates opportunities for a variety of material variations. In our prototype model, we utilized pieces of veneer plywood to create the panels, however, materials with similar bending capabilities could just as easily be used, looking towards materials with high-reflectivity and low heat retention.

Mozambique Preschool Case Competition - Archstorming January 2018-University of Toronto -ARC480 Chris Paez + Kevin Nitiema + Esteban Poveda
Archstorming’s new competition takes us to Mozambique, a country where 70% of the population lives below the poverty line. This difficult economic situation, most severely affects the situation of children. Frequently, the lack of financial resources is a significant barrier to the enjoyment of their fundamental rights. They experience manyproblems; such as the inability to access school, health-care, and housing. The three design objectives for this project were to create a space that could educate, integrate and be sustainable. As an educational space we needed to design kid-friendly spaces that were completely safe for them, a school where they could learn, play, run, and discover. Secondly, since this school will accommodate disabled children and kids facing social exclusion, it is necessary to create spaces where they can interact with each other and surrounding environment. Finally, the project will have to use locally sourced materials, easy to build constructive systems, and should be selfsufficient in energy terms. They have to be respectful with nature in order to teach the kids the proper way to interact with their natural environment.
Offices: one of them will be used by the principle and the secretary and the other one will be used for the school management and janitor
Play Area: big open space where kids can play and have contact with nature. Part of this space will also include an orchard where kids can learn about care and cultivation of the land and collaborate in the long term with the self-sustainability of the institution.

Camera House conceptual project December 2019-University of Toronto -ARC465 Esteban Poveda + Felipe Costa
This project illustrates the transformation between two radically different objects, the camera and the house. This project attempts to capture a moment between this tweening process that captures remnants of both endpoints to formulate a new architectural language. This theme plays into an architecture that doesn’t know what it wants to be, its neither a camera, nor a house. As a result, the “Camera House” is in many ways too designed, but also too vague in concept to be a recognizable structure. It is through this ambiguity that this project can foster a sense of creativity and imagination towards architectural production.
Once this inbetween moment was decided we embarked on the process of rationalizing the thousands of surfaces at our disposal to create a form that was still carried a sense of ambiguity but also communicated the conventional architectural languages of structure, scale, and program. The ‘Camera House’ shows a desire to be a mix-mash of objects that are unconventional and aren’t pleasing of an aesthetic level, but they express an arbitrariness that opens up unique spaces within design.
This series of images illustrates the transformation between camera and house, while highlighting the pivotal mo that tweened between the surfaces of the house and camera.

Timber Framed Gridshell Pavilion Deployable Shading pavilion January 2018-University of Toronto -ARC380 Timber gridshells are a solution to the growing interests of free-form architecture in the context of an ever increasing awareness of the natural limitations of our environment. The characteristics of timber gridshells - long-span, lightweight, affordable and sustainable - argue that it should be a perfect fit to some of the architectural programmes of our time. However, their use has so far been limited to experimental pavilions and a few very worthy, large-scale, permanent buildings. In thiis pavillion, the double layered gridshell method was applied to materialize a unique architectural language of fluidity, inspired by natural ice formations. This lightweight organic roof structure floats on concrete plinths, its soft shape and contour serving as a place of recreation and restitude. This deployable pavillion is designed in such a way as to make it easily assmbled and disassembled on site.
Plan
Doubled Layered Gridshell The purpose of the double layered gridshell is to strengthen the system as a whole, as well as provide room for intersection. The middle layer is comprised of shear blocks that enable horizontal shear between the top an bottom layer. As illustrated above, intersections are compressed by steel compression elements.
