climate + identity exploration center Georgia Tech, Atlanta, US “revelation pulley/hinge” 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. 5

building physics modeling Georgia Tech, Atlanta, US thermal and daylighting analysis 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..

Using the honeybee tool, it was analyzed that the 12 zoned baseline case remained hot in summer months and cold in winter months. The 18 zoned design case with suitable shading and air conditioning allowed to achieve the required thermal comfort levels, the outcome of which allowed to assign suitable function to the zones.

research center for urban waste management Bangalore, India

undergraduate thesis project 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. 21

media modeling Kasugai, Japan

prostho musuem instructed by James Park Team members: 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.

Using the grid system analysis, a Cartesian coordinate of the massing system was identified to determine the coordinate system of the enclosures on all three floors
