Incorporate standing concepts with the essence of the environmental surroundings, which are embodied in the function and form of developing designs.

Objective

Houston has become a metropolis in need of expansion and development. The increasing size of Houston has created an outreach for new ideals implementing the modern involvement of integrating resources and materials. With my dual degrees in Architecture and Environmental Design, I have studied the application of applying new technology and systems; they combine the actions and notions of sustainable design with the design intentions involving the environmental elements surrounding the site.

In observing Houstons diverse structure, I came across two reoccurring themes, the importance of understanding its historical background as well as notifying the future growth for development in new sustainable technologies and design. The knowledge gained from my Environmental Design degree has furthered my research into eco-friendly systems. With the new found ecological conscience designs and information, I am able establish a platform that will suite the growing state of our economy.

Human Habitat for BirdsFort Worths Botanical Garden

Project Awards

Fort Worths Botanical garden was chosen as an ideal site for the Aviary. The site providesresources and infl uences from the adjacent freeway and river that contribute to the development of the Aviary and also acts as the joining point between Fort Worths Cultural Centers and the Nature Preserve.

University of Houston - Senior Undergraduate Design Award- 2010Texas Society of Architects - Studio Design Award Runner-up- 2010

The concept of the Aviary is A Habitat within a Habitat. The Aviary is centered withinthe bird habitat, creating a human habitat enclosed in the bird sanctuary, similar to aninverse bird cage. The program consists of multiple galleries and viewing areas creatinga source for educational and physical interactions with local and exotic birds. It also consistsof sets of classrooms and labs to educate the public and private residences in multiple fi eldsof the Aviary.

Observations taken from the analysis of local and exotic birds conceived the types of materials and formal systems that are affected by the actions of birds and experiences ofbird interactions. The investigation of Texas local bird migration patterns lead way to thedevelopment of the habitat wall that surrounds the Aviary.

Observations from the analysis of local and exotic birdsconceived the types of materials and formal systems that areeffected by the actions of birds and experiences of birdinteractions. My concept is to enhance the average contacts between humans and birds by establishing aprogressive circulation, which fl ows through out the birdhabitat and the human domain, creating a linked experience from the minimal ground experience of birds tothe top of the tree canopies.

Bird defi cation: The defi cation of birds can effect the wear and tear of building materials. Through further research we can uncover the types of materials that are most likly to be defi cated on and further use the conclusion to further the design process in a way that will be able to utilize this seemly randomized process

Longevity of material: Through the analysis of the research I am able to deduce what types of material can best be infl uenced the types of surfaces that will be most likly be defi cated on.

Social-Facilitation: the feeding rate, for example, may be increased when others are around. In other words,when others are around, there is an increase in fi tness.

Local Enhancement: This concept deals with one individual that is successful at a particular location,attracting others.

Information Center: When individuals can learn from each other. For example, bank swallows hunt for insects. The idea is that the swallows are using each other to fi nd the insects. If they nest too early, there are not many others to help fi nd food. Another example is Ospreys feeding for fi sh. Schools of fi sh are also verypatchy. Ospreys that nest near each other can look at other ospreys and see what type of fi sh and wheretheir neighbor Osprey comes from. (For fi sh, such as fl ounder that are not schooling fi sh, a fi nd does notattract other Ospreys to head out in the same direction.

Bird defi cation: The least defi cation happens with this type of statued material. The smooth surface refl ects light that scares birds and is a rough for them to cling to with their talons.

Bird defi cation: Marble is the second least of the statued materials to recieve bird poop. The reason being for the smooth surface and color.

Bird defi cation: Concrete is one of the top materials that birds defi cate on. The rough grooves are easy for their talons to grab a hold of and provides a good perch

Bird defi cation: Stone is one of the top materials for birds to defi cate on. The rough contours provide a perch for the birds and also acts as an attraction for various amouts of birds and the top bird defense is to poop to mark its territory.

The innovation of the bird nest was ideally use to be used as a temporary residence for birds. The unique assembly proviveds a sturdy structure while providing breezes and light to penetrate through, which is the reason for architects interest in it.

The nest further acts as an inspiration for not only abstract structures but also the creation for possible shading devices and air fi ltration systems.

Natural LandscapingBird Structure Bio-FibersThe four major types of bird locations consistof Marshland, dessert, forest and plateaus.The landscaping is what drives migrant birdsto stopping and nesting in certain areas.

With the differentiation in landscapes thesurrounding area as well as the design for the building can consists of multiple variations of plants that will also call different color birds at different times of the year.

Individual feather structure: Feathers are basically constituted of keratin (a tough, inert, insoluble protein substance of microscopycal microfi laments) immersed in an amorphous protein matrix. Keratins are long-lasting biological material resistant to attack by protein-digesting enzymes of microbes or fungi. A feather is a structure composed by a main shaft and a hierarchy of fi ne branching structures extending from either side. The main shaft is the calamus (at the base, where there are no branching structures) and the remaining portion is the rachis. The barbs branch from the main shaft and extend angularly towards the tip of the feather forming a vane. Barbules branch from the closely arranged parallel barbs and from these stems, even smaller structures - the barbicels. The feather appearance is defi ned by the number of levels of branching microstructure.

Advantages Bio-fi bers:Strength The barbed fi bers forming the feather

is the strongest weight to strength ratio on earth. The barbed fi bers provide insulation from the weather and the tight nit hooks allows adjustifi ction and movement.

Color The fi bers are also what creates the

color of the bird as the refl ection of the sun bounces off the fi bers. and the movement of the fi bers creates a manipulation of colors

Keratin fi bers:Created from chicken feathers were used as short-fi ber reinforcement for a poly(methyl methacrylate) matrix. The composites were evaluated via thermal and dynamicalmechanical analysis. The thermal stability and transition temperature were found to be higher than standard PMMA. The storage modulus at room temperature increased with 1% and 2% weight of keratin biofi bers and, at high temperature, the reinforcement provides higher stability, as refl ected in the modulus behavior. Keratin fi bers within the rigid polymer reduces tan peak, indication of a strong interface, as optical images confi rm.

The AviaryThe Aviary was chosen after the analysis revealed that thesite would be an area to provide the resources for such a program. It lies within the reach of the Fort Worth River that will allow for various types of habitats for the birds. The location is in the vicinity of the Garden Center which provides a source for gardens and fl owers that will help attract local Fort Worth birds. The Aviary consists of multiple galleries and viewing areas creating a source for educational and physical interactions with local and exotic birds. It also consists of sets of classrooms and labs to educate the public and private residences in multiple fi eldsof the Aviary.

The layout of the Aviary is centered within the bird habitat, creating a human habitat enclosed in the bird sanctuary. As you puncture through the bird habitat, into the lobby of the Aviary, you begin to travel onto a continuous ramp that shiftsupward. The ramp provides a different bird/human experience at each level. As you progress, from the larger more public gallery spaces of the fl oor, you are elevated into the private sections of the classrooms and private library. The progression of the ramp also provides a division in bird experiences. The lower levels provide a view of birds at the human scale as they interact on the ground level; in contrast to the higher region of the ramp at the bird fl ight scale.

Shelter/ Classic Car CollectionDowntown Transist Center

The Shelter

Program

Downtown transit center site was chosen on the basis that it is located at the division point between the high rise community of downtown and the low rise business community. The division is created by the major freeway that forms a barrier as it circles downtown.

The shelter was chosen after the analysis revealed that the site would be the best area toprovide the resources for such a program. It is located in the local church region, fordonations and spiritual assistance; it is within the downtown area to provide a source for jobs. Its proximity to the grey hound station allows access for transportation. The shelter will provide a source of training and interviewing for the jobless, an express stay area for those that are just passing through and for runaways that are being sent home, a center of health care and counseling,and duplex residences for homeless families.

The program consists of three parts, a 150 car collection, a shelter/ work source, and a 900 car garage that will supply both programs. With the extreme functionality created by the opposing programs, they are placed on opposing areas of the site to separate the introverted and self-sustaining personality of the shelter and the extroverted and social consciousness of the car gallery. With duel programs within the garage, the parking garage becomes a type of urban fabric itself, by connecting these two opposing programs through vehicle and pedestrian circulation. The structure of the garage is a light weight steel structure that surrounds the precast concrete massings of the shelter and collection. The skin wrapping the garage is a perforated aluminum cladding that is used to conceal the garage, as it protrudes through the split level of the master plan, into the public realm. It also acts as a binding unit that restrains the two programs at the core of the garage.

Observations from the analysis of the downtown area conceived that the buildings that were highly populated formed clusters with one another, through the connection of walkways and sky ways. My concept is to use the separation of public and vehicular circulation that the sky ways provided and apply it to a bigger social realm. This can be achieved by completely separating the two circulations by dramatically splitting the ground plans. The splitting of the levels provides access to the buildings on multiple levels and provides a barrier between people and vehicles. The elevated ground also acts as a connection across the freeway from the downtown area and the low rise businesses.

The layout of the shelter is divided vertically, with the core administration at the base along with the class rooms and work source and the residential amenities up above. The division is a result of the intersection of the shelter and the elevated ground plan provided in the master plan. The administration, being more organized and formal, is below the split level with the residences, being more open and social, are exposed to the upper social realm of the split. The car collection is also affected in the same ideal, with the work load of the mechanics and wash bays on the bottom and car collection is place above within the publics view.
