Abstract
Digital architecture, as a proceeding architectural style, has caused fundamental evolutions in architectural design and building appearance via applying complex geometries and topologies. Computers and digital tools have truly altered the design process and architectural conception facilitating production of new eye catching forms. Avant-garde architectural forms have emerged from these changes in architectural design geometry which have influenced visual, physical and morphological features of cities. In this article, the impact of digital architecture and various architectural types (topological, isomorphic, motion kinematics, metamorphic architecture, parametric, genetic) on cityscapes of different periods (ancient, contemporary and future cities) is explored. Through these digital tools, the cityscape of ancient cities, which are not available to us today, can be revitalized. Digitally designed urban spaces and forms can influence contemporary cityscapes and urban landscape due to their complex geometry and free forms, assisting cities to become museums of avant-garde architectural elements and attractive magnets for capital and tourism in globalizing world. These digital tools will have a profound influence on future cities with their parametric design, morphological patterns, digital façade fabrication systems and other methods. This paper is mostly focused on digital production of forms and urban landscape by elite groups (designers, planners, digital experts etc) and thus the effects of other economic, policy-making and more procedural aspects of urban design on the final product (city scape, urban morphology etc) are not applied here.

Abstract
Urban morphology, including buildings’ typology and their configuration, affects sky view factor and insolation, which are two of the most influential parameters in urban microclimate. These become even more important in extreme environmental conditions. In this research, challenge was to generate various rule based urban morphologies in a parametric environment. Then, to evaluate them based on mentioned parameters to find the fittest climate responsive morphology. The evaluations are done using grasshopper definitions connected to Ecotect and genetic algorithms in grasshopper in a relatively short computing time. Introducing a high speed and user-friendly environment for designers to introduce forms and evaluate them in several iterations was a main consideration. The tool consists of two parts. First, the generative algorithms to create various rule based morphologies. Second, the analysing algorithms, which find the fittest climate responsive urban morphology based on insolation and sky view factor. As a case study, the program is used on different urban morphologies in Yazd to find the fittest solution. Gaining the maximum sky view factor while having minimum insolation on building surfaces is ideal in hot and arid climate. Anyhow, these two suggest contradicting solutions for urban form. Based on the existing urban fabric in Yazd, various block typologies and their arrangements are generated parametrically. In each scenario, iterations of evaluation find the most suitable ones. After comparing the fittest versions of different types, the most proper building typology, collective arrangement of them and the best orientation are provided as result.

Abstract
For years, research on daylight in work environments with different climates has been important for researchers to distribute light evenly in the indoor space in order to create a healthy work environment and visual comfort. This study examines the effect of horizontal and vertical shading devices, the depth and distance of louvres on daylight with the aim of increasing DLA (daylight autonomy) for Abrisham tower in Tabriz, Iran. As input parameters the depth of louvres was considered 5 and 15 cm and their distance were considered 150 and 200 cm. Modeling was performed in Rhinoceros software and the Simulation was done in Grasshopper plugin to control the geometric parameters and with the help of ladybug and honeybee plugins. The multi-objective simulation tool, octopus was used to optimizing. Results show that vertical louvers caused more light reduction. Furthermore, the simulation effects of shaders parameter's include depth and distance being examined and analyzed, it seemed that the distance between louvers in this case and in Tabriz is more important variable and moreover, using reflective material or coating on louver’s surface as there are many weeks are overcasting theirs in Tabriz can help and improve internal light autonomy. The optimal cases that were obtained for north façade windows are horizontal louvres with a depth of 5 and a distance of 190 cm and vertical louvres with a depth of 15 cm and a distance 200 cm. In south facade are horizontal louvres with a depth of 13 and a distance of 161 cm and vertical louvres with a depth of 14 cm and a distance of 153 cm.
