The thesis Defense session of Mr Shokohi Dehkordi,Kaveh with the title of“ Comparative
evaluation of methods for producing architectural sketches in the early stages
of the design process
Abstract :
The
era saw the rise of technology in all areas of life. Digital technology,
information and communication technologies and computers are the themes of
these technologies. Information technology and computers have made many cultural, social
and economic developments on human life. Architecture is also one of
the most effective sequences. Today, architectural design and production
processes, tools, ideas, theories, methods and forms have been affected by
computer and communication technologies extensively.
The
increasing use of computers in architectural design and engineering is one of
the most recent human achievements in promotion and enhancement of the efficiency
of the various stages of construction
design process.
The
early 1960s saw the advent of the
computer has been used in many areas. computers were used in the construction
industry and their application has grown in the field of architectural
processes. Nowadays, the computer have become one of the main tools used by
architects and engineers in the architectural profession and the building
construction.
In
recent years, extensive studies have been done about CAD and CAAD. These
studies suggest that the arrival of the computer to architecture design process
occurs in three steps. The steps are : Early stage of architectural design ,
Drawing and design stages.
This
paper studies the use of computational tools in the early stages of the design
process . and the effects of CAD compared with traditional and manual design
tools. The role and impact of communication technology in the architecture is
studied. Theories about design, architecture and the initial stages of the
design process, the use of computers in the early stages of design and
computerized design tools have been carefully studied. In order to investigate
the applicability of computer tools early in the design process of
architectural evaluation and Sketchup software was selected as the best of
them.
The
main purpose of this thesis reviews the impact of computer applications in the
early stages of the design process. Therefore, the comparison between
architectural design method by various devices is conducted. In this
thesis ,the material and methods are experimental research and survey. In this research, three methods of
architectural schematic drawings (sketching) as main activity is related to the
early stages of the design process, including methods of sketchting with computer tools, traditional tools and
combination methods (both of computer and tradiotional devices) are compared
with each other in the study statistics population.The computer tool is to be
used in the early stages of architectural design is Sketchup which is defined
the most appropriate tool for the early stage of architectural design. In this
thesis, an experimental sketching design was held and a jury group that was of three master of
architectural design course, judge the sketches and evaluate their scores.
Judges' scores were based on the criterias were defined during a survey to
assess the sketches.
For
the analysis of data of this thesis we use judges scores, factor analysis,
multivariate analysis of variance test questionnaire - MANOVA. Statistical
studies show that the architectural sketching method is effective on the grades
and students performance. Also according to the test scores of students in the
three groups of participants, sketching group with traditional tools (paper and
pen and clipboard) achieved the highest scores.
Finally
the comparison between computer and traditional design tools show that computer
tools can not be a substitute for
architectural design in the early stages of design process and traditional
methods contain manual tools are still preferred.
