TOWER OASIS Type: Academic Teammates: Yuyang Liu; Aaron Deroux School: University of Illinois at Urbana-Champaign Professor: Paul Armstrong Studio: High-rise and Habitat studio Year: Fall 2019 Site: 320 North water st., Chicago, IL

Located in the bustling downtown of Chicago, this tower is a high-rise building which is meant to act like the Oasis of the area. Self-contained in every way this tower features a hotel, residential units along with various amenities including a business center, spa, restaurant and a co-working area. The key feature of the building is however the series of sky-gardens which twist their way throughout the building vertically. These sky gardens offer unique views and act as the interactive hubs of the tower. Moreover, the sky gardens are also deigned to act as the lungs of the building. By allowing natural ventilation, the sky-gardens of the building in a way “breathe�.

Broad design intent:

33

Creating a loop circulation for the visitors that reflects the shape of the race track around and creates an efficient viewing experience for the visitors.

E and wings removed E and WW wings removed

The main idea behind this proposal was the movement of visitors as they circulate through the exhibits. A linear movement was considered because it offers lesser chances of missing out on an exhibit. To avoid passing through the same exhibits again, a linear circulation was considered. The loop was then raised to different heights to capture views and to facilitate a narrative in the exhibits. This idea helped create a central atrium/ lobby flooded with light and around which all the circulation happens.

Boundary Conditions

OBSERVATIONS AND INFERENCES: Over the three year period of simulation run, it can be observed that despite large fluctuations in exterior temperature, the interior temperature remains steady at about 20 degrees Celsius to 25 degrees Celsius (68 degrees F to 77 degrees F). Thus the proposed wall assembly proves succesful in creating a thermal barrier. The Relative Humidity falls rapidly at he vapour barrier stage (can be observed in the profiles) and the interior RH fluctuates anywhere between 20% to 50%. It has been shown that this fluctuaiton is acceptable while considering prevention of condensation onto the interior of the building envelope. The water content in the wall assembly remains high in the exterior brick veneer layer but drops after the vapour and misture barrier.

EXPERIMENTAL ENVELOPE Type: Academic School: University of Illinois at Urbana-Champaign Professor: Scott Murray Elective: Experimental Envelopes Year: Fall 2019 Site: Miami, FL

This course was designed to study in detail the envelope of buildings. It involved a project of designing the envelope for an office building located in Miami, FL. The design was done in four phases. The first phase involved the design of a geometry for the envelope. It included the creation of 3 iterations with 15%, 30% and 60% glazing respectively. The second phase involved the design of shading devices and studying their impact on the energy consumption and daylighting within the building. The third phase included adding materiality to the wall section including insulation, fire proofing, drop ceilings and flooring. The final phase studied the impact of PV on the energy usage of the building. The major observations of the project were that the project, located in Miami, had maximum energy consumption for cooling. Heating energy needs were negligible. This energy need and the EUI number was drastically improved by shading devices which played an important role especially in the south and the west facades. Reducing the SHGC and infiltration rate, PV panels on the roof also helped to drastically improve the EUI number.

PASSIVE HOUSE DESIGN Type: Academic School: University of Illinois at Urbana-Champaign Professor: Scott Murray Elective: Independent Study on Passive means of climatic control Year: Fall 2019 Site: Blue Ridge Mountains, Virginia

This was an independent research project done to study the various ways of passively combating climatic conditions in various sites across the world. It involved the study of various examples in different climatic zones around the world. After this, a small residence was to be designed in one of the studied locations, Virginia. Virginia’s climate is such that it has almost equal number of heating degree days and cooling degree days. To achieve passive cooling the important steps taken in design were high thermal mass for walls, location of maximum glazing to south to achieve winter solar gain and an attempt has also been made to achieve passive heating and cooling by convective flow of air. The main design idea was to explore and push the boundaries of a traditional Trombe wall. The space in between the thermal mass wall and glazing in a Trombe wall cross section was expanded to create living double height spaces. During the winter the solar gain from the glazing causes the hot air to rise and is sucked into a cavity wall by the mechanical means of a fan. The hot air releases energy to adjacent spaces as it cools, and the cool air moves down and a convective cycle is achieved. During the summer the windows are kept shut and fresh cool air is drawn in through Earth tubes into the cavity wall. As the cool air gets heated up by the thermal mass, it absorbs heat from adjacent spaces (thus cooling them) and rises and is exhausted by stack ventilation.

DEPLOYABLE STRUCTURES Type: Academic School: University of Illinois at Urbana-Champaign Professor: Sudharshan Krishnan Course: Planning and design of Structural systems Year: Fall 2018

This is a series of three projects meant to explore movement and transformability in architecture. The first of the three projects involved the design of aa deployable sphere using the mechanism devised by Chuck Hoberman. Often called the Hoberman sphere, this project involved the study of angulated scissor members to achieve concentric motion. The second project involved the same principles of motion using scissor elements but employed in a larger scale to a saddle or pringle shaped geometry. The chosen geometry is an anticlastic surface and is a part of a larger hyperboloid structure. The motion or deployment is seen in both the positive curvature and the negative curvature. The third project was the study of kinetic facades and the mechanism of motion. It involved mathematical calculations and geometrical construction to achieve multiple modules to move with one single mechanism.
