Design Idea

This research aims to find innovative design solution to create sustainable compound residential towers in Aleppo city, for the reconstruction phase, by using the concept of sustainability and benefiting from natural energy sources. International organizations and many countries are interested in applying sustainable architecture standards, reducing emissions, mitigating pollution, and reducing long- term operating costs for buildings by making the most of natural resources. Tower buildings are among the most important design models that have been subject to the concepts of sustainability and their applications, due to their consumption of large amounts of energy. This research presents a study of a sustainable design for a residential compound tower, for the reconstruction phase in Aleppo city, using the genetic algorithm within the Grasshopper program. The tower design Idea depends on developing and linking the basic design idea of ​​the project with main design determinants such as dimensions, heights and other variables, including location and climatic characteristics, and then creating a barometric chart for these connections within the Grasshopper program. This chart links to the Galapagos tool, which is responsible for running the genetic algorithm. The random structure is generated when the algorithm started, and as a result of the cross- breeding, more advanced generations are created. The process continues to reach the most appropriate environmentally sustainable form to reduce the heat load acquired in summer. The model is evaluated environmentally using Ladybug simulation software, to provide solutions for modular residential towers that fit the local environment of Aleppo city. The results of the research showed that the solar heat load was reduced by adopting the genetic algorithm to find the most suitable configuration for the tower. The amount of reduction is 35% between the initial solutions and the final approved solution. The research also revealed that the use of green roofs reduces the heat load by 20%. The research also showed the effect of using shading facades. On the southern, western and eastern directions, the heat gain was reduced by 5%.

Abstract A Genetic Algorithm (GA) based approach for solution of optimal control design of flexible structures is presented in this paper. The method for modeling flexible structures with distributed parameters as reduced-order models with lumped parameters, which has been developed previously, is employed. Due to some restrictions on controller design it is necessary to make a reduced-order model of the structure. Once the model is established the design of flexible structures is considered as a feedback search procedure where a new solution is assigned some fitness value for the GA and the algorithm iterates till some satisfactory design solution is achieved. We propose a pole assignment method to determine the evaluation (fitness) function to be used by the GA to find optimal damping ratios in passive elements. This paper demonstrates the first results of a genetic algorithm approach to solution of the vibration control problem for practical control applications to flexible tower-like structures.

Information is transferred through a process consisting of an information source, a transmitter, a channel, a receiver and its destination. Unfortunately, during different stages of the engineering design process, there is a risk of a design idea or solution being incorrectly interpreted due to the nonlinearity of engineering design. I.e., there are many ways to communicate a single design idea or solution. This paper provides a comprehensive review and categorization of the possible sources of information loss at different stages of the engineering design process. Next, the authors present an approach that seeks to minimize information loss during certain stages of the engineering design process. The paper i) explores design process and dissemination methods in engineering design; ii) reviews prior work pertaining to these stages of the engineering design process and iii) proposes an information entropy metric that designers can utilize in order to quantify information loss at different stages of the engineering design process. Knowledge gained from this work will aid designers in selecting a suitable dissemination solution needed to effectively achieve a design solution.

Ismar David was a prolific calligrapher, type designer, graphic designer, and illustrator who also engaged in architectural design and taught calligraphy. He studied applied arts in Berlin, emigrating to Jerusalem in 1932 and to New York in 1952. From the 1930s to the 1990s, he created a wealth of unique designs, most importantly the David Hebrew typeface family. It was the first comprehensive Hebrew typeface family, comprising nine styles that include a true Hebrew italic style and a monolinear style, equivalent to a Latin sans serif. David Hebrew provides an example of how a research-based design process can help negotiate the tension between old and new, leading to an innovative, well-informed design solution. David not only excelled in his groundbreaking approach to Hebrew type design for existing glyphs, but he went a step further, expanding the character set. After David completed the design of his typeface family in 1954, it was partially cast for machine composition by the Intertype Corporation. During that period, David relocated to New York to pursue his creative career.

Abstract: Islamic architecture appears not only as mere ornament, but is a media that plays an important role that has its own charm for every visitor/user, because a good design must respond to geography, location, climate, size, culture and others. The dome-shaped mosque building has thrived in the Islamic world and has become a symbol of expression of the structure and identity of a mosque. However, in the last two decades, many mosques without domes have appeared in Indonesia. Mosques with modern geometric elements are increasingly standing majestically in several areas in Indonesia. Some architects began to eliminate the dome element in the mosque, but still displayed Islamic values. One of the mosques without a dome is the Great Mosque of West Sumatra. The design is a square building that instead of a dome but instead forms a gonjong. The design of the Great Mosque of West Sumatra was criticized by several figures in West Sumatra, who said that the design of the mosque was unusual because it did not have a dome due to some literature stating that one part of the mosque was a 'dome'. news about the existence of a mosque ornament which is claimed to be a form of motif commonly used by Jews (Pentagram). The purpose of the study was to identify the design idea of the Roof of the Great Mosque of West Sumatra which describes the shape of the stretch of cloth used to carry the Hajar Aswad stone, the concept of three symbols: the springs (the elements of nature), the crescent moon and the Gadang House. The method used in this research is descriptive qualitative. The results of the study indicate that the value and meaning of the architectural design philosophy of the roof of the Great Mosque of West Sumatra, which is represented by the architect in its design concept, has a lot of compatibility with the mosque building that has been designed. The concept is very clearly visible so that even ordinary people are very easy to understand.Keywords: Mosque Roof, Bagonjong Roof, Representation Abstrak: Arsitektur Islam muncul bukan hanya sebatas ornamen semata tetapi merupakan media yang berperan penting yang memiliki daya tarik tersendiri bagi setiap pengunjungnya/pemakainya, karena sebuah desain yg baik harus merespon geografi, lokasi, iklim, ukuran, budaya dan lain-lain. Bangunan Masjid berbentuk kubah telah tumbuh subur dalam dunia Islam dan menjadi sebuah simbol ekspresi struktur dan identitas dari sebuah masjid. Namun dua dekade terakhir ini di Indonesia mulai banyak bermunculan bangunan masjid tanpa kubah. Masjid dengan unsur-unsur geomotrik modern semakin banyak berdiri dengan megah di beberapa wilayah di Indonesia. Beberapa arsitek mulai menghilangkan unsur kubah pada masjid, namun tetap menampilkan nilai-nilai Islami. Salah satu masjid tanpa kubah tersebut adalah Masjid Raya Sumatera Barat. Rancangannya berupa bangunan persegi yang alih-alih berkubah tapi justru membentuk gonjong. Hasil rancangan Masjid Raya Sumatera Barat pernah dikritik oleh beberapa tokoh di Sumatera Barat, yang menyebutkan rancangan masjid tidak lazim lantaran tidak memiliki kubah karena adanya beberapa literatur yang menyatakan bahwa salah satu bagian dari masjid itu adalah ‘kubah’, bahkan ada beberapa keraguan tersebut yang berhembus kabar tentang adanya bentuk ornament masjid yang diklaim sebagai bentuk motif yang biasa dipakai orang Yahudi (Pentagram). Tujuan penelitian adalah untuk mengidentifikasi gagasan desain Atap Masjid Raya Sumatera Barat yang menggambarkan bentuk bentangan kain yang digunakan untuk mengusung batu Hajar Aswad, konsep dari tiga simbol: sumber mata air (the springs: unsur alam), bulan sabit dan Rumah Gadang. Metode yang digunakan pada penelitian ini adalah deskriptif kualitatif. Hasil penelitian menunjukkan bahwa nilai dan makna filosofi desain arsitektur atap masjid Raya Sumatera Barat yang direpresentasikan oleh arsitek dalam konsep desainnya, terdapat banyak kesesuaian dengan bangunan masjid yang sudah dirancangnya. Konsep tersebut sangat nampak jelas terlihat sehingga orang awam pun sangat mudah untuk memahaminya.Kata Kunci: Atap Masjid, Atap Bagonjong, Representasi

The aim of this paper is to research the impact to emerging theory based on the relation between the architect and his work in a digital approach to the process of design and realization by the principle of Digital Chain. Digital Chain is an uninterruptible digital process consisting of design (idea, coding, geometrics), through construction (structure, junction, prototyping) to production (fabrication) with every step as a programmed entity connected by CAAD/CAM technology universal interfaces. The term Digital Chain is defined and researched (theoretically, experimentally and practically) by the CAAD Chair at ETHZ within the research projects of this institute. Digital Chain is not continuous without the role and position of the architect as the fluid energy and expert that investigates how digital technology is changing, i.e. the entire process of the chain, simultaneously adapting to it.In that sense architecture appears as an open work (Umberto Eco) without final definitions and in a constant process of information motion as the main component of the architectural product caused by the demands of context, function, form and user input. Testing design code through changes of parameters in iterations, as well as checks in prototype on the next level, makes the theoretical playground between experiment and experience, through education and expertise. It is examplary that interest in the process (performance) was larger than the representation (appearance), what Deleuze and Guattari call supremacy of the Gothic spirit over the spirit of Romanesque or classical spirit, where Gothic deals with the generation of Gothic architecture by understanding the forces, trends and behavior of the material from the bottom to the top, contrary to the classic generation that deals with the imposition of visual aspects such as the proportion of top-down. This paper considers experience or posteriori knowledge as the main driver of the emerging theory of the Digital Chain. Article received: December 26, 2016; Article accepted: January 23, 2017; Published online: April 20, 2017Original scholarly paperHow to cite this article: Cvetić, Mariela, and Slađana Marković.

Optimal Set

Abstract Engineering decision making involving multiple competing objectives relies on choosing a design solution from an optimal set of solutions. This optimal set of solutions, referred to as the Pareto set, represents the tradeoffs that exist between the competing objectives for different design solutions. Generation of this Pareto set is the main focus of multiple objective optimization. There are many methods to solve this type of problem. Some of these methods generate solutions that cannot be applied to problems with a combination of discrete and continuous variables. Often such solutions are obtained by an optimization technique that can only guarantee local Pareto solutions or is applied to convex problems. The main focus of this paper is to demonstrate two methods of using genetic algorithms to overcome these problems. The first method uses a genetic algorithm with some external modifications to handle multiple objective optimization, while the second method operates within the genetic algorithm with some significant internal modifications. The fact that the first method operates with the genetic algorithm and the second method within the genetic algorithm is the main difference between these two techniques. Each method has its strengths and weaknesses, and it is the objective of this paper to compare and contrast the two methods quantitatively as well as qualitatively. Two multiobjective design optimization examples are used for the purpose of this comparison.

This paper presents and discusses an optimisation approach applied to spatial layouts in care home building design. With this study, we introduce a method for increasing the floor plan efficiency using a self-organising genetic algorithm, thus reducing energy consumption, improving the wellbeing of residents and having an implicit impact on the costs of energy and health care. In order to find an optimal spatial configuration, we elaborated and tested a number of design criteria based on existing literature reviews and interpreted through initial considerations of care home layouts. These are used as objectives in a Genetic Algorithm (GA) to evaluate the best design solution. The self-organised floor plan is then used to run a final simulation to observe how residents could use the optimised spaces and to measure the improved efficiency of the new plans. The paper concludes with the discussion of the results and some considerations for future studies and experiments using emergence behaviour models to improve sustainable development in design.
