Evait Labib Architecture Student

when coming to the course learning experiences , i would say without any doubt that it was unique and different from any other course in the 5 year plan; it was not easy but challanging to think about creatures and get inspired by the nature around us. This allowed me to think about architecture from onother prespective related to abstraction and biology as a concepts to consider. At the begining of the semester i was quite struggling and falling behind as i didnot know how to continue the thinking. It was difficult to deal with the programs but i know that i can reach a whole new level in the design with the help of those tools.

I am student majoring in Architecture Engineering and minoring in psychology . i look forward to learn something new in everyday life . studing architecture made me realize the importance of having an eye on details and the impact of the user groups on the design process.

The design must be considerate to the site to be more succesful.

This storybook shares my journey through physical/digital exploration, algorithms, development, research, translating meanings into physicality as much as I could. It was a ratherenligthening journey, so I hope you enjoy every chapter of this story.

I see that architecture is a science helps in balancing between the tangible and intagible factors that effect the human comfort we focus on aesthetics but with the structural logic, atte tion to detail, and again coordination. and it has its own beauty drived from arts

Project description and site:

In this project, we are required to design a mobile shelter for the homeless. we are encouraged to develop several alternatives and design ideas as part of your preliminary search for a language of formal expression that responds to basic aesthetic and functional requirements. Your projects should lie within the governorate of Minya. This entails an awareness of the specific context you are designing within and how it informs and inspires your design and character. The design is open-ended in terms of the required functionality, form, and number of residents, to allow you to generate innovative ideas; it should however lie within the range of 40-50m2 ARCH 473/3522 - Spring 2019

It is located in Upper Egypt.

Al-MinyÄ (140 miles [225 km] north-northeast); Minia is one of the major governorates in Upper Egypt that encloses a number of important monuments The governorate is considered one of Egypt’s agricultural governorates, The most important crops are cotton, wheat, corn, potatoes, and sugar cane

The site for me was very familiar as its my home town and i used to live in till i joined the university so i felt a little bit attached to the project and the idea of designing to the people i may see in my daily life. i was also excited to get inspired by the natural inspiration there. For me i didnot choose a specific plot rather i decided that it would be more benificial to design a module that can be placed in more than one plot

The inspiration was based on the evolution of the tortoise besides the abstraction of the keywords.

The main inspration was based on the idea of different layers with different forms , shapes and sizes as the case of the evolution

Abstraction to movement and spine

Interlocking spines

Tortoise: biomimicry

9 In the for generation phase my intent was to transform the key fast vs slow movement words i extracted from the inspiration or i got from the key word to be translated into abstractions and 3 d form. the 3d form was inspires from the curves then the integration between 2 pipe intially and each one has its own charachter and properties then i applied my conncept to each one to create the different curves and rips in the 4 phases i got from the evolution of the turtoise

The form adabted to the function and the site conditions as well as the project requirments but i had difficulties applying the proper scale in the site as my model was large at the begining but at last i manged to do it.

i tried to produce the technique that results in the least time possible so I choose the tringulation technique . The technique produced time of 1 day and 7 hours and 33 minutes . This stepped helped me to visualise and understand how the model would come from a virtual drawing to a real model and to imagine how i would reasemble it ARCH 473/3522 - Spring 2019

Climatic Analysis Our assigned building, Blom Bank, is located on South Teseen Street. The facade that we will be working on is a southern facade , which means that it is exposed to the sunlight and heat radiation all day long.

solar irradiance and orientation

south facades (with 45 variations ) seems to be the most effective to builldings with double skin facades .

Outdoor Air Temperature

wind direction.

whithin the cavity

improved airflow rates in the cavity are created when double skin facades are protected from

High solar angles are unfavorable to the inducement of high air temperatures and stack effect

Solutions

shading devices should adequately control shortwave radiation transmission into the userspaces The challenge of increasing ventilation rates in hot periods may be acheived by applying effective comibned facede and building design parameters.

Parameters

There are four main factors in phase 2 of the course that acted as a parameters for the second phase of poject two which are the mixture as the best ratio was 1:2 gypsum , fixation points as the more fixtation points the more the form can be controlled , formwork as it is the main indicator of the shapes, forms and sizes of the module and finally the fabrics as it is creates the curvetures .

preliminary Ideas initial plans and sections that demonstrate the idea of the double skin facade and how it depends on the main focal points.

First trial on grasshopper which was sussesful in viewing the nodes and variations but wasnot successful as it did not consider the 4 factors or the stategy

section that shows the different how the wind reacts with double This model was more succesful as it applied the factors, strategy skin facade nodes and focal points and parameters Portfolio

Prefinal Idea This trial on grasshopper was sussesful in viewing the nodes and variations in the sizes of the 2 screens as well as the panels in the outer skin it was also succcesful in stiking to the main concept and design parameters such as the human comfort which was in the curveture and the responsive sun panels in the outer skin of the facade

the plans varies from one floor to the other in order to accomudate to the different function of each floor

My idea was to produce a double skin facades made of two skins; one is static and the other is responsive to the human comfort as well as the sun path . The idea wasnot successful as the inner screen were not shown at all and it would be a waste of money and efforts if it were added only as a decorative element and donot have function ARCH 473/3522 - Spring 2019

Final Model

the plans varies from one floor to the other in order to accomudate to the different function of each floor . it also shows the fixation points that are responsible for creating the facade curvature

The Sections Created different spatial experiences according to the space protruded in the ceilling that effect how each plan is formed acording to the space Environmental experience : getting exposed to the fresh air (wind ) and enjoy the natural light in shaded areas The more we move to the west , the more increase in the open area inside the skin Portfolio

this figure shows How the double skin faรงade responds to the wind direction in order to provide proper ventilation as it is open towards the west direction which is the previling wind direction.

This figures show how the panels responds to the sunpath movement trough out the day in different hours. it also shows how it opens and closes in response to the sun .
