Design and Research Studio | fall’20 | Fabricated Homescapes Debora Mesa Molina This studio was a space of questioning and investigation, to reframe our ideas about housing and its urban role and to refresh obsolete paradigms. Here and through the agency of architecture, we designed dense mix-use prototypes that creatively speculate with contemporary forms of domesticity and urbanity able to reinstate lost urban values. Part and Parcel refers to a portion of something that is integral with the whole, which in the case of this project refers to housing modules that together form the community parcel. The design seeks to solve problems of affordable living among the growing senior population and the students of LA with the proposal of an inter-generational mixed-use vertical structure which not only provides for spaces to inhabit but also to grow produce and sell the surplus in the grocery store which will be accessible to the general public, thereby promoting a self sustainable living environment.

Atlanta Public Library
Portman Studio | spring’20 | Adaptive Resuse Project Prof. Jude LeBlanc The 2020 Portman Prize Studio explores regenerative building, an approach to the conception, design development, and technical specification of architecture that seeks to radically reduce its consumption of raw material and non-renewable energy resources throughout the building lifecycle and reshape design practice to ameliorate the current degradation of global environmental health. The main objective of the project is to reuse and refurbish the H.L.Green Building into a new Public library by retaining the existing brick clad shell and by adding a new CLT structure on top. The main architectural function performed on the building is the staggering of the floor plates in order to allow for interior transparency. When viewed in section this creates a tight central core with large double height spaces on either side. This subtraction also lets more light into the structure and most importantly reduces the carbon footprint due to the removal of materials like steel and concrete.

Revelation pulley/hinge
climate + identity exploration center | Advanced Studio Prof. Frederick Pearsall The Baker building site lies in the vicinity of the other research facilities of the Georgia Tech campus, after recording and analyzing the site it was found that despite being rich in its natural and cultural characteristics, it’s identity remains concealed. Marking positions of the trees that previously existed with glass stele, a guided path along these is designed such that the observer is made to experience the highs and lows of the topography and the interplay of light and shadow cast by the tree canopy on the ramp and the stele. Playing with the perception of the observer through concrete poetry etched on the stele, Revelation Pulley functions as a machine system by amplifying forces of nature and therefore tries to bring the hidden identity of the site into light. The Climate Lab needed a space that allowed the work of the researchers to be made aware to the public. Revelation Hinge thus consolidates various functions and stratifies them to provide identity that balances researchers’ need for privacy with the increasing importance of interdisciplinary collaboration and display of work to the public.

Research Center for Urban Waste Management
Undergradute Thesis | Spring’18 Prof. Jotirmay Chari, Prof. Vishwas Hittalmani A trend of significant increase in municipal solid waste generation has been recorded worldwide. This has been found due to over population, industrialization, urbanization and economic growth. A systematic diagnosis and treatment has to be done to solve this problem from its roots in urban areas. The project thus focuses on providing a space for research to be carried out and for management of waste, consultation and public interaction. The design process for the same was thus, the research center being of primary importance in design, I further conducted case studies on a few research centers in Bangalore and abroad and gathered suitable design features. To support the cause of zero waste, I researched on materials created out of waste used in construction and buildings constructed out of the same. A suitable site was then chosen and statistical information of the waste generated in its surrounding region was collected. As a result a campus built out of recycled waste materials that allowed for self efficiency was designed.

Slum Regeneration
Urban and Regional Planning | Fall’17 Prof.Kanika Bhansal Bangalore, along with many other cities in India, aspires to be a slum free city.According to the Karnataka Slum Development Board, the city has at least 600 slums. However, the Association for Promoting Social Action (APSA) has said that the city has over 1,500 non-notified slums which are not counted by the government and that at least 25% to 35% of the population resides in slums all over Bangalore. The challenge for this urban design project is to develop various models, in groups, for the settlements in Vinobha Nagar, JC Road, Bangalore by taking into consideration the immediate as well as future impact of our action in order to benefit the community. The site selected for this studio is representative of 80% of slum pockets in the city in terms of living conditions and ownership issues. The site inhabits around 200 families on an area of 1 acres, leading to a density of 200 persons per acre. About 50% of the residents are working class and the other 50% are students, housewives and elderly. The houses here are a mix of 1-3 storey permanent and temporary. Even though the typical household belongs to the low income group, they are very much a part of a progressive society where aspirations are high.

Prostho Museum
Parametric Modeling | Fall’19 Instructor: James Park Team: Bryce Truitt, George Doyle, Prerana Kamat Kengo Kuma designed the Prostho Museum in 2007, which was completed in 2010. His source of inspiration for it came from the assembly system of Cidori, a traditional Japanese building set for children. Cidori is a collection of wooden sticks, notched together to make longer or shorter components without metal hinges or nails. The gridded system of Kuma’s Prostho Museum is known as voxel architecture in the digital world. A voxel, which represents a value on a regular grid in a 3D space, is not explicitly positioned or constrained to a specific value. The building was studied in terms of building systems-massing, enclosure, roof and frame which would together give us the parametric output of the building. The derivation and variations were made after analyzing each of the systems as explained below.

Energy Modeling
Building Physics Modeling | Fall’19 Dr. Tarek Rakha The advanced studio project was undertaken to develop massing iterations using thermal and daylighting performance simulations. Using ladybug tool the site analysis was conducted which helped in understanding the sunpath, wind and temperature patterns and the psychometric chart which enabled in making design decisions. Starting from a linear rectangular, two floored layout, the iterations developed to the hinged form which would allow more light into the interior spaces on the lower floor. The overlit spaces were treated with brise soleil/ louvered system. This lighting analysis was conducted using Diva. The building evolved from a 12 thermal zoned rectangular form to an 18 zoned hinged form which performed better thermally through appropriate selection of materials made using the Honeybee tool on Grasshopper.. The functions withing the building were then located after reviewing the thermal performance. The thermal load-heating and cooling, were then tested for the base model and the final hinged form to analyze the improvements in the annual loads.

Site Analysis
From the site analysis it is apparent that the site located in within the Georgia Tech Campus, Atlanta receives extreme temperatures throughout the year. The psychometric chart reveals that thermal comfort level lies between 23-26°C and these temperatures are observed during few days of the year, hence natural ventilation is not feasible.

The graph represents the total floor normalized heating and cooling loads for the building. As expected, due to location, the energy use in heating is larger than cooling. Summer months use only cooling and Winter months use only heating. Overlaps between heating and cooling occur between the months of March and September Heating and Cooling loads were reduced but the lighting loads increased due to the increase in number of thermal zones in the hinged form. However the overall EUI reduced by 100+kWhr/m2.

Climate Studio
Environmental Systems | Spring’20 Dr. Tarek Rakha Team members: Ameya Yawalkar, Jane Rodriguez, Kiran Balakrishna, Prerana Kamat This course focuses on the active systems in buildings and how they impact the design of the building and vice versa. The objective of this course was to equip us with an understanding of these systems to design a building in concert with building systems. The goal of our project was to understand the role that location, environment and climate have on design and how we can integrate design with sustainable building systems to achieve energy efficient buildings. This was achieved though a series of exercises in modeling, simulations and data analysis thereafter. Simultaneous precedent studies further assisted in the understanding of various systems and strategies currently used in similar climatic conditions and assisted in choosing the most efficient solution for our project type.

Design Summary
The overall integration of all these systems seeks to reduce energy usage intensity (EUI) across its building. Research shows that a projected saving of 2-3% over the first year in refernce to a baseline year is a good estimate. Quantifiable benefits of such an approach would be lower energy and maintenance costs, reduced pollution, slower global warming and better energy reliability. The qualitative benefits that are hard to measure would include a healthier well-being, increased student productivity and security in the knowledge of assured energy supply.

Building Simulation | Spring’20 Instructor: Roya Rezaee, Tyrone Marshall, Marcello Bernal Team members: Kiran Golla, Prerana Kamat This modeling and simulation course the following domains: Parametric Modeling, Solar, Energy, Air Flow and Ventilation, Daylighting, View, Statistical Analysis, and Data Visualization. computational techniques to generate a large space of design options, simulate a variety of building performances, evaluate and explore the options, and make informed design decisions in a systematic f ramework called Design Space Construction (DSC) that was developed at Perkins & Will. The f irst strand of the course dealt with fundamental knowledge of building modeling and simulation use of parametric tools and introduction to techniques of multi-criteria optimization tested on 799 Broadway Building by Perkins and Will. The second strand comprised of a selfinitiated design project focused on the development of an integrated model and the application of a realistic design decision making process. Working in a team, we f irst formulated the research questions, investigated precedents, and constructed parametric relationships that described the geometry and program conf iguration using DSC. We then evaluated the design options for multiple objectives, analyzed and visualized the data, extracted the insights, and formulated guidelines for design.

Hive - The future of disaster relief
HUGO Design Sprint | Summer Internship’20 Corgan-HUGO Team: Javier Rodriguez, Rachel guo, Sabrina Bae, Prerana Kamat A network of deployable healthcare modules tasked in providing relief to communities affected by future disasters. The module offers a solution to maximize hospital capacity, reduce response times, and provide adequate medical accessibility. This new network challenges the systems we know today with the technology we are adopting for tomorrow. With Hive, more efficient and agile solutions to disaster relief and management can be unearthed, and we can return our sights to the sky.

Each module is equipped with Internet of Things (IoT) enabled devices tasked to collect data and exchange information. Information like real time capacity numbers can inform the network of where to send more modules and redirect others to the appropriate locations. Concerns of IOT security can be solved with the use of block chain based technology. With this, patient information would be securely kept under the network, available to the patient when requested. During “off peak� times, the modules are docked offshore.
Docking in water would prevent the modules from taking up limited land, casting unwanted shadows on buildings, and being an overall hindrance to the community. Strategically placed around the world, the network is prepared for another disaster at any moment. The landing pad works as a floatation device in the water, the propellers are still operable allowing the Hive to travel by water.
