Thermo-Structural Design

Designing the coupling Energy-based Designof structural tectonics and thermal flows This thesis explores the feedback loop that can be created between a structural system and a thermal scheme in order to develop a deeper understanding of the synergies and clashes between both systems. This project also investigates a multi-topology design language that capitalizes on an existing structural network to carry out selective thermal exchanges in a hot desert climate.

The intention here is to tune loading distribution to thermal opportunities on several scales and merge the concerns of thermal and structural design.

Multi-scale optimization is carried out to address the architectural implications of the union of both these fields.

The tested design proposition works with a “less-mass� system, to tune the inosculation of flows in a thermal resistance scheme.

The conductive matrix that is an integral part of design for structural purposes is being assigned a thermal function The circulated water is used to dissipate the accumulated heat in the day.

Different heat exchanger functions can be assigned on different sides- depending on orientation

Cellular porous geometry is used to maximize thermal resistance. Where the material needs to be allocated, the cell size is smaller.

The challenge is in finding the right cell size for insulation power and stiffness. Decreasing cell size works better structurally because of the increase in material- whilst more material means higher conductance since insulation performance relies on increasing air volume

Living Office: Designing a Ventilation Scheme IBPSA (International Building Performance Simulation Association) Competition Entry The aim of this project is to design and test a mixed mode ventilation strategy for an office building located in New Delhi, India. In order to reduce energy consumption and mitigate effects of high pollution rates, we chose to focus on a ventilation scheme that both operates naturally and filters the incoming air.

Lighting design, airflow assessment and overall energy usage become integral indicators for design features such as façade design, interior arrangement, program distribution and material selection. The design needs to demonstrate that all these features operate under the ventilation scheme while reducing the overall energy demand.

Simulation tools are used to test complex synergies of an idea in a practical scenario. Using these tools in their appropriate limitations, together in a comprehensive methodology, opens up possibilities of creativity in Design, not only functionality. Our explorations are in pursuit of a symbiosis between simulation and design.�

Abu Simbel: Visitor Center Energy-based Design

Climate Analysis

Located in the South of Egypt, next to the temple of Abu Simbel, this visitor center capitalizes on the site‘s potentials to achieve a reduced energy load.

The temple constructed in 1264 BC is a very significant monument that rests on a large stone mound.

Many challenges are faced in this region, where high summer temperatures result in high cooling loads. Our evidence-based design strategies focused on ways to maximize solar intake in colder months while minimizing overheating in the summer. Energy, Daylighting and Ventilation Simulaations were all part of the design process.

Energy Simulation Iterations Using Design Builder an assessment tool, different forms were modeled in order to reach the lowest EUI (Energy Use Intensity). Moreover, the temple mass was modeled to factor in the shadow cast on the building.

The result was a bermed mass, where the surface area exposed to direct sunlight was reduced. This reduced the cooling load significantly. and helped in reducing the overall energy consumption. Other design stratgegies implemented included the use of evaporative cooling, clerestorey windows and local stone walls as thermal mass.

In order to optimize the daylighting strategy, DIVA daylighting simulations were caried out. The pink areas above represent overlit areas, while the blue represent under-lit spaces.

Using clerestory windows resulted in a more even distribution of light within the space while the roof skylights were not as effective.

04 Location: Boston, USA Illuminus Light and Technology Festival October 2015

Quantitative Aesthetics: Real-Time CFD An Interactive Light and Technology Installation This project sets out to investigate the visualization of airflow based on computational fluid dynamics methods (CFD). The aim was to augment a sense, or rather bring forth an experience of airflow that is both highly visual and inaccessible to our senses.

CFD uses numerical methods to both analyze and predict air flows in a steady state condition.

Objects and people in a field disturb flow and create collisions and flow convergence.

Energy driven designs use CFD as a tool to understand air and fluid behavior in space. Such methods are slowly materializing in the design discipline but are being deterred due to complexity and extensive computing time. These visualizations are also static and isolate themselves from the physical realm of interaction.

Hence, we set out to bring this experience of flow to people through light. Our intention for this project was to bring forth intrinsic qualities of a CFD model and manifest them in three dimensional space such that they have a sensorial dimension. Instead of using complex simulation engines, we utilized coding to have access to the root equations governing fluid flow.

The Installation was part of the Illuminus Light and Technology Festival in Boston and was exhibited in both Fenway Park and Boston House of Blues.

Interactive Structural Analysis

The aim of this project is to enhance the ability of designers to visualize and compute structural analysis within a short period of time. As a real time interactive tool, its intention is to familiarize people with everyday shell structures as well as assist in early stage form finding. Based on loading conditions that are inputted by the user, the shell structure is analyzed within the modeling interface and the user can mold the outcome as they wish to achieve the most optimal outcome. The loading conditions are inputted in the beginning of the analysis using color detection. The Kinect picks up this data as well as the modeling process and maps the analysis in real time on the object.

ANALYSIS

Surface shell analysis, material selections and different colors assigned to wood, clay (modify thickness and material, modify the form to have less stress points and deflection) using Millipede- a structure analysis plugin developed by Panagiotis Michalatos and Sawako Kaijima

SHELL STRUCTURES The objects to be modeled are fabricated in advance before the analysis is projected. A few iterations of the same form family can be prepared

CONTROL PAD The control pad allows users to switch between the view type for display. For minimum information the nodes can be diplayed without the color gradient showing the structural analysis.

OPTIMIZED STRUCTURAL FORM After the kinect sensor picks up the depth data and form of the shell, an optimized is displayed here where the deflection of the structure is at its minimum value

3-D ANALYSIS VISUALIZATION The compression and tension analysis is displayed here in 3-D view. The user can rotate to view the shell structure from several angles

ANALYSIS GRID This grid is intended to project the analysis on the obbject as the user models in real time. Through color detection the sensor picks up the supports (red) and the loads (green)

levels of interactive visualizations: Structural Analysis: A color gradient is assigned to the detected surface based on the stress distribution both in plan view. The amount of stress is computed based on load conditions(quantity and position) and support conditions inputted in the system and is mapped on the object. Two main interactions can happen: - Adding loads - Removing loads by color detection 3D Deflection visualization: Based on the support conditions and computed stress, the system outputs a visualization of the potential/exaggerated deflection of the shell structure analyzed.

This appears alongside the main plan view analysis.

Stress Distribution: The analysis has an overlay of vectors that represent the stress vectors on every quad of the structure. This part of the analysis assists in narrowing down the areas that have a high concentration of stress and the direction of stress vectors.

Optimization: Providing instructional assistance, this visualization computes the optimal shell shape based on the support locations, material and thickness inputted by the user. This is calculated once and is intended to provide hints for the user during the modeling process.

Active Architecture: Thermal Panel An experiment in Adaptive Regulation The aim of the project is to create a structural panel that exhibits thermal response and helps to regulate the indoor environment. This application focuses on a ÂŹflooring system that incorporates a structurally supportive geometry (honeycomb) and a phase change material that responds to temperature change. The metallic conductivity on the metal helps retain the temperature and aids in the stabilization of the phase change material. This enhances the energy storage capacity (in hotter temperatures) and energy emitting (in colder temperatures).

The panel is calibrated based on the comfort range of 18C- 24 C of indoor environments.

Through a series of tests, the substance and geometry was optimized. The project aims to have a visual dimension where changes in temperature and slab activation can be visible through thermochromic dye that changes color through temperature. That way the inhabitants can be more aware of their environments.

Net-Zero Design: Housing Re-trofit Energy-based Design

The re-design was carried out in the aim of upgrading the building’s envelope to both achieve significant energy reductions and perform better in terms of climate response.

Existing buildings in the US represent a big portion of energy consumption. The challenge becomes in providing upgrades for exiting construction, rather than just new buildings where architects must be well-aware of a building’s performance. In order for this to be carried out effectively, it is necessary to evaluate all changes in terms of impact, benefits and quantifiable cost savings versus initial construction expenditure.

The existing design was first analyzed and simulated to identify problems and potentials for improvement. Following this, strategies for improvement and assessments that inform the design decisions are carried out.

Daylighting and energy simulations are used calculate predicted energy consumption and generation.

During the summer months the Southern Double skin facade is opened to flush out the accumulated heat

During the winter months, the Southern sunlight is absorbed by the double skin facade. The double skin facade is closed to trap this heated air and help warm the house, reducing the heating load. An outlet to the interior circulates this heated air in the slabs.

The accumulated heat absorbed by the inner facade is re-used via a heat exchanger located below the foundation of the house

EcoTourism: Desert School Extrapolated growth of a desert node In a country utilizing only 5.5% of its land, the move to the desert in Egypt has been long overdue. A successful desert settlement must be established to set an example of what the future of urban planning can become in Fayoum Oasis. This project aims to use an Eco touristic site resource to provide an educational platform that would in turn offset the growth of a community and plant the seed for a much needed sustainable desert development.

The school becomes the embryo of the community, connecting the two attractions, Wady Al Rayan and Lake Qarun. These connections become growth axis, opening up channels for agricultural development and making it the dominant mode of growth whilst forming an attachment to the arable 'desert island'. Within this agricultural expanse, the school acts as a medium for production and a catalyst for future development.

The school aims to combine the three goals of Ecotourism; enhancing social welfare, raising environmental awareness and creating job opportunities. The program includes a range of composting and recycling spaces. Natural heritage and communal learning plazas act as pockets that stimulate social learning.

Lower Ground experience: The design aims to introduce an unobtrusive feel to the surrounding setting by taking the students under ground rather than above.

The lower ground level is supposed to expose the students to the whole project expanse while simultaneously opening them up to the whole surrounding environment. There are five plazas in the project that act as pockets of social interaction. They are connected through a network of circulation, linking all green spaces.

Daylighting is maximized through this arrangement- those pockets dug underground also infiltrate the light into the project spaces.

Shading analysis has proven that building height would not over shade and obstruct this lighting.

Structural Synchrony: Hall of the People Transitional Dualities create Human Progress Based on literature analysis, this project merges text and architecture. Through the several analogies drawn, a statement was developed and manifested in a structural entity that guided the design of the "Hall of the People".

This statement was a result of recognizing the dualities discussed in the studied text and how they shape behavior and alter motives- thus creating human progress.

The idea of the hall of the people focused on themes that are in transition. In order to acquire knowledge on an individual level one must start off with physical individualism. We then progress into mental and social individualism untill we reach ultimate individualism- the spiritual Individual.

The experience in each component was analysed and experiential models were constructed based on the degrees of enclosure and exposure desired in the space. The implications of structural response through a space frame system were tested.

The ground floor plan was designed as the base for the complex's experiential path. Inside, the user is exposed to the space frame members in various spatial applications.

Hence the user becomes one with the building and all it has to offer from experiences.

The structure modules act as units of progression as the user enters the complex. The four keywords represent four stages of self actualization and represent different dimensions of individualism. Starting with Knowledge, a library becomes the first experience where the user interacts with learning.

The second learning experience is compromised of different social spaces within a Collective setting. Interaction with others brings forth the exchange of ideas and a type of growth on its own.

Individual

The third stage is where the user interacts with Natural elements, in the outdoor garden. This experience is key to spiritual development in the process of self actualization.

Reaching the highest point of the project, spiritual individualism is manifested in the form of Individual yoga and meditation room.

Experiential Models

The lowest level is where the auditorium is situated. Reaching the ground level, the library, cafeteria and offices can be found.

The First and second floor represent a mixture of experiences where the individual is placed in a more educational collective environment.

The Ground level is where the gardens and outdoor spaces are housed. This represents the height of social interaction.

The third level represents the height of individualism and is composed of individual meditation rooms.

Expo Milano 2015: Cluster Design Feeding the Planet Energy for Life Cluster Design: The cluster aims to replicate and recreate a micro-Mediterranean city. Feelings, colors and flavors all merge together to create a unique cultural experience that is imprinted in the visitor’s memory. The design emphasizes on the elements of comfort and being at home where cultural boundaries are erased and reformed in the light of the newly merged cultural fabric.

Materials: During the six month duration of the exhibition, a set of materials with both durable and aesthetic qualities are be selected. Concerning the units, a double skin system will be used. This will consist of an upper section composed of perforated metal panels and a lower section with polycarbonate installations. The upper perforated part will have the patterns of the units, creating an interesting composition of light within the interior space.

Role in Project: - Designed Pavilion environmental “skin�

Cluster Arrangement

The skyline of the pavilions was designed to replicate the irregularities seen in mediterranean city skylines. The pavilion is double skinned to allow for the circulation of air between the unit layers. In almost all Mediterranean architecture, pattern becomes behavior, responding to the needs of occupants and controlling light. In this case, the facade permeability creates a unique interplay of light and caters to the ventilation needs of the pavilion.

Insulation must be used to shield the solid part of the house from heat gains during summer and heat loss during winter.

VIP (Vacum insulated Panels) are an effective way to cater to the insulation needs of the house.

The open house plan allows for ease of air distribution. Ceiling exhausts will be used and will be housed within the false celing.

Absorption chiler technology will be used to cool the house.

The glass segment of the house will be shielded by the perforated screen layer.

However during winter months, the screen will be opened and the glass will be exposed.

In order to optimize internal temperature, triple glazing will be used.

A grey water system will be used to treat water and reuse it in the toilet and irrigation deck network.

Magnetic Order: Business Hotel Shaping social spaces

Topography Configuration Location:6th of october, Sheikh Zayed, Cairo, Egypt 3rd Year Individual Design Studio

As a business hotel, this project aims to fuse a professional setting with a more open contextual experience. The concept of magnetism is adopted to shape the project elements and view circulation and negative space as a "field of interaction"- defining the scope of social behaviour.

A desert climate also mandates an environmentaly conscious design-optimizing lighting performance, materials selection and internal environment. Surface analysis as well as interior path analysis is conducted to enhance the performance of all open spaces.

Streamlining topography allowed for easier integration with the building forms. The land lines intersect and shape the internal project platforms and levels-forming a seamless merge between site and mass.
