Free-form Facade Shop drawing Istanbul, Turkey | 2018 In cooperation with EMRE ISTIKAM Co Role: Writing the generative code which convert the wire mesh model to full detailed BIM model
View III
Vakifbank headquarters, which is mainly designed by Tabanlioglu architects in 2013, is a 43 floors tower in Istanbul containing more than 250,000 sqm usable area. According to the architect, the Bank would like a reference to the ancient heritage, with a glimpse into the Islamic patterns born out of mathematical wisdom. The motives should be not referred to superficially but the basis on which the main structure is to be designed. Therefore instead of an ornamental faรงade, the oriental vision of its designers was reflected in the building structural form. This results in a facade that contains various freeform shapes which are not easily buildable in conventional ways. Our mission in this project is to make a plugin which can convert a wire mesh to final BIM model and generate shop drawings. Experience gained through the previous similar projects has paved the way for a flawless progress in this one.

Free-form Facade Shop drawing Baku, Azerbaijan | 2017 In cooperation with EMRE ISTIKAM Co Role: Writing the generative code which convert the wire mesh model to full detailed BIM model
The new 170-meter-tall building composed of five twisting cubes of different sizes standing on podiums. The building boasts a unique geometric design due to its twisting forms and pioneering building services. The sophisticated architecture and modern building services made the MOT Tower a landmark project in Azerbaijan. Unitized curtain wall system used in this tower, contains non-planar glass panels which could not be built easily. Therefore, the main objective of this project was to find the best planar panel closest to its non-planer counterpart for each unit in such a way that the overall shape of the building would remain intact. Next, it was crucial to suggest an efficient method for producing the shop drawings for those panels. Because of the gradual slight change of each panel, the drawing process could be tremendously hard for any draftsperson. Thus, we wrote a code in grasshopper that could accomplish this task in no time and error free.

FREEFORM SPACIAL FRAME
Tehran, Iran | 2016 In cooperation with EMRE ISTIKAM Co Role: Writing the generative code which convert the wire mesh model to full detailed BIM model
The aim of this project was to find a way to automatically create the shop drawings for the freeform spatial frame system. Each and every element, joint or glass sheet in these structural systems are geometrically unique. Therefore, it would be tiresome for a draftsperson and takes a lot of time to prepare their shop drawings one by one due to the variety of shapes as well as human errors. Thus, our approach in this project, we to create a code in grasshopper which would convert the wire mesh of the structure to a full detailed model (BIM). Through this program, the need for an operator to make a model, generate the shop drawings and check the errors was resolved. This solution makes it easy to design and construct freeform spatial frames. Hence the designers can now generate a simple wire mesh and immediately see the real-time full detailed model. Up to 2018, two different free-form surfaces were designed and built in Tehran and one is being designed in Istanbul employing this code.

MEGA-PARS
Tehran, Iran | 2016, Spring In cooperation with SAITAL SAKHT Role: Energy Consultant for facade
Mega-Pars, The first green mall in the Land of Persia, manifests a high degree of sustainability in various aspects making it a distinguished project in the whole area. Energy issues were the crucial points for our client in this project. According to the project scale, optimization of each item had a considerable effect on the building total energy consumption in the long term. Each of the proposed façade systems was evaluated by conducting general energy analyses such as solar radiation, Illuminance, energy consumption and thermal bridge. By improving some determinant details in the curtain wall system we could optimize the façade heat transfer rate dramatically. This process helped our client not only by keeping the currently used materials which were considered to be replaced but also resulted in a great positive effect on their financial benefit and scheduling. Mega-Pars won the special Prize of Energy Globe World Award due to its carefully designed details and its founders’ attitudes toward energy issues.

ATLAS MALL CENTER
Tehran, Iran | 2015 summer In cooperation with SAITAL SAKHT Role: Energy Consultant for facade
Atlas Mall Center is a commercial building located in Tehran, Iran. Its façade consists of several different materials such as double layered glasses, ceramics, aluminum panels and a vertical garden. To choose the best material configuration for this building, we relied on energy consumption and illuminance analyses. During these analyses, it was found that the location of the vertical garden would have a crucial effect on both heating and cooling overall consumption we focused our attention to finding the best location for the vertical garden. Shifting the vertical garden by only 12 meters reduced the energy consumption of the building by around 10%. Furthermore, studying the influence of different types and colors of glass led to much lower energy costs during the project’s lifecycle. Optimization of the energy consumption as well as the location of the vertical garden was done using genetic algorithm, grasshopper, DIVA, honeybee and rhinoceros software.

TRANSFORMABLE FACADE
Tehran, Iran | 2016 In cooperation with ADIB Architects Role: Designing the transformable mechanism
View III
A private green open space like a terrace, flourished with flowers is a must have for nowadays residential buildings in urban environments. To Achieve the most possible green space without compromising the privacy was the main objective in this project. The idea was to merge the garden concept with the apartment simple facade. Therefore it was decided to make a transformable facade to satisfy the need for both the green space and controlling the everchanging conditions of the environment. Several horizontal wooden structures were developed as parts of a mechanism to form a dynamic facade. This mechanism can be activated by only one actuator. When the actuator is triggered, wooden blades fold together in order to change the facade to its desired form. Even though it looks planer when closed, the variety in the sizes of the blades results in different shapes for the facade.

CLOAKED IN BRICKS CONSTRUCTED
Tehran, Iran | 2014 Spring Role: Associative Designer, Facade designer and fabricator, in co operation with ADMUN STUDIO http://www.archdaily.com/775030/cloaked-in-bricksadmun-design-and-construction-studio (2016) 2 Gold Medal, in “Architizer A+ Award” in the USA, in “Brick” category with Visitors and Jury. (2015) Honorable Mention, in “Memar Awards”, in “Residential Apartment” category, Tehran, Iran.
This project is a façade which covers a residential/ official building. The façade was designed paying special attention to some key features of Iranian traditional architecture such as privacy and using vernacular materials. As such it was desired to be built mainly from yellow brick while being novel and deconstructive per the client’s request. So near the openings, each brick was placed over the below one by a slight rotation around a vertical axis to let the light in. In order to manufacture and build the façade, a steel structure was designed and the breaks were prepared in such a way to be kept together by long screws. Two carefully positioned holes in each brick defined its exact rotation angle. In order to have bricks at various angles, we used a milling machine and read data from the Grasshopper. The details devised for assembling of the parts in such a way that only the bricks and the vertical steel bars remained visible from the inside.

ADIBE EXCHANGE
Tehran, Iran | 2017 In cooperation with ADIB Architects Role: Modeling and shop drawing of the free form part
In this project, we planned to design the space by emphasizing its functionality. This objective could be achieved by bolding the ceiling as the most visible part. Suspended cylinders positioned freely in the air like a fluid would show the dynamic and consistent economic activities and money transfer around the world, in this exchange office. The client was determined to contribute to the design process. So an algorithm was written by our team in grasshopper to give our client the ability to participate in the design process. He could test and evaluate his various ideas seeing the results in a computer by only changing a few parameters. Then detailed shop drawings for all the elements were provided for the client to make the construction process as flawless as possible.

MOSHIRI OFFICE
Tehran, Iran | 2017 In cooperation with IWAN Role: Modeling and shop drawing of the free form part
The interior designers of this project had the idea of a continuous surface with geometrical patterns in mind to cover the wall and the adjacent ceiling behind and over the reception desk. Parallel ribbons shaped like sine waves were to be built using reinforced gypsum. These ribbons had to be divided into smaller pieces and put together closely then finished carefully to compensate their discontinuity. As skillful architects in the computational design, we provided them with the digital drawing documents. Our parametric approach was to write a code in grasshopper in such a way that sine wave shape of the ribbons would change according to the distance of the surface to the reception desk. Pace and precision to produce the shop drawings were of utmost importance.

MODERN LAMP DESIGN Tehran, Iran | 2016-2019 In cooperation with MONJI co. Role: Designer
Being a classic light fixture manufacturer itself, our client wanted to produce modern and minimalistic lamps for their new market. So the objective was to design innovative modern lamps while lowering the production costs and assuring the increase in sells. LEDs and SMDs were used for the light emitting parts, steel and wood were used for the body parts considering our client being a wood manufacturer and the lamps were designed with these main features in mind: - The possibility to assemble and disassemble the light fixtures easily. Lamps are packed and transferred much more efficiently when they are not assembled. - The possibility to change the form or adjust the light illuminance by moving the parts or the mechanism. This would give more variety and lighting options to the users. - Considering wood as the most viable material option in the design process. That would lower the costs significantly. Transformability of the lamps caused serious challenges in the design of the conductive parts, so they had to be delicately and cautiously designed.

PLY-HOUSE WORKSHOP Tehran, Iran | 2017 Summer In cooperation with CEAT Role: Manager and Instructor
In this fabrication workshop, the main objective was to design and manufacture of a tiny house for emergency situations. Thus, we needed a small house which could be built easily by ordinary people. Students were limited to design considering only plywood and CNC milling machines as the most available materials and tools for this purpose. They were constructed to form several groups to present their ideas in the first part of the program. They accomplished the task in three months. In the second part, one concept was selected by the instructors to be built at the real scale. Hence students made a BIM model of the house, prepared the construction drawings and assembled the structure successfully. This workshop was held at the University of Tehran, Center of Excellence in Architectural Technology with 20 participants.

NEXORADE WORKSHOP Tehran, Iran | 2016 Fall In cooperation with CEAT Role: Manager and Instructor
The “Nexorade” Structure, also called Reciprocal frames, is a kind of construction which do not have joints and elements, called Nexor which means link, lay on each other to create cladding. The workshop with the focus on design and fabrication was held in three steps: familiarity with the subject, producing simple models and building the final structure. In the first step, after introducing its logic, students were asked to design and manufacture a simple geometrical surface, without using a computer. Next, they designed another one digitally and used laser cutters to build their 2 in 1 meters models out of plywood sheets. Finally, the tutors selected one among all the students’ models to be built by the participant’s contribution. Plastic pipes and a rotary CNC milling machine was used by the students to build the final structure. The workshop progress documents are available on the following page. It is the official page of the workshop which is open to everyone interested.

HINGE PANELING WORKSHOP Tehran, Iran | 2015 Fall In cooperation with CEAT Role: Manager and Instructor
The Hinge Paneling Workshop is one of the most important events ever held by the Computational Design Committee, in the University of Tehran. With 56 participant students, this workshop revealed many interesting ideas in response to some predefined problems with the focus on fabrication methods and itâ&#x20AC;&#x2122;s considerations. The living hinge is a cutting technique which is used on rigid materials in order to make them flexible. For example, as it is shown in the pictures, bent surfaces are made from hard plywood sheets cut by a specific pattern. The workshop was held in three steps: familiarity with the subject, producing simple models and building the final structure. In the first step, after introducing the hinge logic, students were asked to design a parametric cutting pattern and test it on small pieces of paperboard. This trial and error step took a day. In the next two days, each team of students was asked to choose a product topic. In the final step, they were coordinated to construct their final product which took them four days to complete. In this step, they were asked to design architectural panels, something like an interior curtain wall, a partition or an exterior shade system considering to use only 3mm plywood sheets. The workshop progress documents are available on the official web page of the workshop which is open to everyone interested.
