    Fenestration guideline for energy and daylight efficiency: Evaluation and prediction of performance in office buildings
    By Ko, Dong Hwan, PhD, 2009
    Abstract (Summary)
    The primary significance of this paper is the development of guidelines that can help in defining fenestration properties and design factors to increase building performances. Since the influence of fenestration on energy consumption is well known and proved, in order to encourage the development of appropriate designs to ensure high performance office buildings, fenestration guidelines have been developed. The main results of this research provide the necessary criteria with respect to fenestration in order to meet daylight requirements and conserve energy. These fenestration criteria are targeted at architects and designers to facilitate them in the selection of the U-factor, SHGC, VT, and window-to-wall ratio (WWR). Further, the application of the abovementioned method can result in more energy-efficient buildings, which, in turn, can assist in attaining an LEED green building rating system certification.

    Investigating Laminated Bamboo Lumber as a viable structural material in architectural applications
    By Rittironk, Supreedee, PhD, 2009
    Abstract (Summary)
    Laminated Bamboo Lumber, or LBL, has been used in many architectural products; however, it is still new as a structural material in building construction. Bamboo, as a renewable material, is used to produce LBL, so that it can gain sustainable benefit. Many experiments using LBL as a building and construction material have been demonstrated globally however, there is no strong evidence of the commercial use of LBL as structural material. This research investigates the viability of LBL in three major parameters; structural, architectural, and sustainable parameter. The methodology used consisted of a thorough literature review and the physical testing of LBL beams analyzed with parallel calculations. In physical tests, other wood engineered products, other than LBL beam specimens, were used as controls for comparison. They are Laminated Veneer Lumber (LVL), Glue-laminated Timber (Glulam), Parallel Strand Lumber (PSL), and Oriented Strand Lumber (OSL). The final aim is to endorse the use of LBL as a viable structural material, and furthermore, to aid in the adoption of LBL as a widely used structural material in architectural design.

    An Architectural Score: Recording and orchestrating an architectural experience
    By Barragan, Rodolfo, PhD, 2008
    Abstract (Summary)
    An architectural experience is by essence an indivisible entity; in order to be recorded it needs to be fragmented, losing its condition of a Unitarian whole. In this study, I intend to solve this contradiction by developing the conceptual and instrumental frameworks for a correlated system whose output I have called "Architectural Score".

    I_Prefab Home: Using internet & query approach of customizing prefabricated houses
    By Chuen-huei Huang,Joseph , PhD 2008
    Abstract (Summary)
    This research identifies the methods of applying mass customization concept into today's prefabricated modular housing industry. Although the concept has already been implemented in the computer, clothing, and automobile industries, it has not been fully integrated in architecture, especially in the housing industry which is more directly related to personal life style. One of the arguments in this thesis focuses on the current implementation that is not fully functional to address the consumer's needs by selecting the product's appearance only.

    Integrating space planning technology with form generation
    By Hsu, Ying-Chun, Ph.D., 2007
    Abstract (Summary)
    Throughout the history of computer-aided design, digital tools have been developed in variety to assist a designer during the design process. With the tremendous improvement in computer technology, CAD systems as well enhanced their functions and capabilities for designers to extend their imagination and creativity through different ways. However, most recent commercial software is developed for designers to quickly reproduce their design result, or analyze elements of their developing projects. Designers still spend a great amount of time solving design problems, which include site analysis, space planning, and architectural form study, known as "schematic design".

This study is aimed at providing architects/urban designers more informed choices for building design in a changing urban climate

    Post occupancy evaluation of assisted living facility
    By Lee, Jeoi Hun, Ph.D., 2006
    Abstract (Summary)
    Many elderly people who move into assisted living facilities do not feel comfortable and do not feel the physical setting of the facilities adequately fit with their physical profiles. Frequently, the cause is the gap between the physical environment of the facilities and elderly people's previous homes as well as their physical profiles. The purpose of this study was to examine the relationship between the physical and social characteristics of assisted living facilities (ALFs) and users' satisfaction/dissatisfaction, to explore the potential usefulness of the concepts of universal design in the design of ALFs and suggest further policy and design guidelines to produce quality improved environments.

    Comparative analysis of energy performance between courtyard and atrium in buildings
    By Al-Dawoud, Abdel-Salam, Ph.D., 2006
    Abstract (Summary)
    In this analysis, the energy performance of a central atrium is investigated and compared with the energy performance of a space with the same geometric proportions but open to the sky at the top (courtyard). The atrium design used for the analysis is square in plan and surrounded by the building on all four sides. It is covered at the top with a skylight. The glazing type and percentage for the courtyard walls and atrium skylight are varied in the analysis. Weather data from four cities representative of climatic conditions of cold, temperate, hot-humid and hot-arid were used. The main variable under study was the building height (number of floors), particularly to investigate under what conditions of climate, glazing type, glazing percentage, and number of stories it would be beneficial, from an energy performance aspect, to cover an open courtyard with a skylight to create a conditioned atrium. The computer energy simulation program DOE2.1E was used in this study as a tool to evaluate the impact of these factors on the energy consumption of both building types and their alternatives.

    Integrating building code analysis within the architectural design process into the building information model
    By Satti, Hassan Mahmoud, Ph.D., 2006
    Abstract (Summary)
    Architects are obligated to develop building designs that conform to locally adopted Building Code. To visualize any building code related problems in their design, architects go through a manually tedious search process for relevant building code sections which have no consideration to the architectural design process.

    Development of form finding of tensile structures: An architectural approach
    By Tamai, Hiroki, Ph.D., 2005
    Abstract (Summary)
    Due to the advancements in new building and material technologies, a great number of tensile structures have been developed to be incorporated with various types of architectural projects for the last three decades. Today, tensile structures are widely recognized as a potential design vocabulary in contemporary architecture. One major obstacle in the design process, however, is that tensile structures have no rigid form of their own; they have to be shaped to the desired form. The creation of such a form requires in depth knowledge and understanding of the stability and behavior of tensile structures. The form must be designed in such a way that all the tensile structural members are in equilibrium. The procedure to determine such equilibrium forms, which are adequate structurally as well as aesthetically, is referred to as form finding. Existing computational form finding methods can generate prestressed double-curved surface geometry, but architects are not well prepared to make the best use of these methods.

    Tall building form generation by parametric design process
    By Park, Sang Min, Ph.D., 2005
    Abstract (Summary)
    Historically, the development of the tall building has been dependent on technological advancements. As the continuous advancements of technology impacted tall building design and planning, the architectural profession also changed to keep up with the rapid technological progress. One of the recent remarkable technologies is the use of the computer to analyze complex structural systems and its ability to produce construction documents. However, digital tools to assist in architectural design to generate innovative tall building forms have not progressed at a comparable rate.

    An XML initiative of transferring architectural information to the construction site based on the BIM object concept
    By Ibrahim Mahmoud, Magdy Mohamed, Ph.D., 2005
    Abstract (Summary)
    The primary communication method between the construction site and the architectural information had mainly been the highly symbolic two-dimensional manually drafted drawings which were interpreted by architects and the construction personnel for the purpose of constructing the building. When computers and affordable Computer Aided Drafting (CAD) software were introduced to the Architecture, Engineering, and Construction practice the same drawing legacy continued.

This energy-based interfacing program is intended to help architects, engineers, educators, students, building designers, major consumers of architectural services, and other professionals, whose work interfaces with that of architects, perceive, quickly visualize, and compare energy performance and savings of different design schemes.

    Space efficiency in mixed-use high-rise building
    By Kim, Hyeong-Ill, PhD, 2004
    Abstract (Summary)
    Mixed-use high-rise buildings first appeared in the mid 1960s. They now play an important role in urban commercial business districts. This building type must be an effective solution to solve the space problems generated when dealing with mass amounts of commercial, office, hotel, and residential space. The space efficiency is simply referred as ratio of rentable area over the gross area and it depends on the core area of the building. In mixed-use building, since the core is generally more complex than these necessary for single-use buildings, rational combination of functional distribution is very important. Distribution of each function will affect the core planning accordingly. Because space efficiency is closely related to the ratio of functional distribution, which means percentage of functions in a building, combination of function components has to be very carefully analyzed.

    Solar Effective Envelope Design Advisor (SEEDA)
    By Mahaek, Ekkachai, Ph.D., 2003
    Abstract (Summary)
    The lack of effort by mainstream architects in integrating energy-efficient strategies in architectural designing is due to the complexity in a building's energy conscious concepts and theories, the difficulties to visualize and quantify energy consumption, and the late implementing of energy consumption analysis in the conventional design process. This task would be accomplishing by a building system's engineer where results might be determined only after the basic architectural design has been completed. An effective simple tool and method should then be available to assist architects in building's energy-efficient designing at the beginning of the design.

    Ends of Imperium: Rethinking the Architecture of the Modernity at the Limits of Modern Architecture,
    By Sam El Khar Baweyi, Ph.D., 2003

    A parametric study of the interlocking stack effect ventilation with building thermal mass in commercial buildings
    By Boonyaputthipong, Chumnan, Ph.D., 2002
    Abstract (Summary)
    The interlocking stack effect ventilation with building thermal mass is the strategy that takes advantage of natural phenomenon and building structure in purpose of providing passive heating and cooling benefits. It has been successfully used in many buildings, particularly for residential-scale buildings. However, for the diverse loads of larger scale commercial buildings, the benefits of interlocking naturally derived convective heat transfer with building mass needs more in-depth study.

    Discovering architecture within a seashell
    By Jirapong, Kamon, Ph.D., 2002
    Abstract (Summary)
    The structures in nature are great lessons for human study. Having been in development for several billion years, only the most successful structural forms have survived. The resourcefulness of material, the underlying structural systems and the profound capacity to respond to a variety of climatic and environmental forces make natural structures tremendous exemplars to man-made structures. Their superior design is worthy of study.

    Integrated resource-conscious planning toward sustainable communities
    By Lee, Byeong-Ho, Ph.D., 2002
    Abstract (Summary)
    For planner/architects, the concept of sustainability offers a balanced methodological framework between the concept of environmental protection and the high resource consumption of current development.

    Integrating the geographical and cultural phenomena of the Mississippi River, New Orleans and the Chao Phya River, Bangkok
    By Petavanich, Pollawat, Ph.D., 2002
    Abstract (Summary)
    Rivers are sources of life. They connect people spiritually and culturally and have supported human life from its inception. Misunderstanding, neglect, and rapid industrialization of rivers have created a loss of connection with the daily activities of people. The purpose of this dissertation, Integrating the Geographical and Cultural Phenomena of the Rivers, is to present a fundamental approach upon which architecture and planning could bring life back to the river and to create pleasant riverine communities for the future. It is important for architects and city planners to create an environment that will encourage people to care for the rivers. This includes maintaining the memory of the rivers.

    Identification of barriers to the building integrated photovoltaic design process as applied to curtain-wall
    By Sozer, Hatice, Ph.D., 2002
    Abstract (Summary)
    The use of renewable energy sources, such as photovoltaic (PV) modules, is increasing all around the world mainly for two reasons: the negative environmental impacts of the use of fossil fuels in energy conversion, and the increasing costs of non renewable energy consumption. Also, there is an increasing interest in sustainable or environmentally-compatible building design. Renewable energy resources, particularly Building Integrated Photovoltaic (BIPV) technology, are very popular components of sustainable design. Even though there are many examples of BIPV in the world, integration within the building processes has not been clearly defined at this point. This lack of definition makes this technology application more expensive and complicated than it is supposed to be. The challenge is how to make this new technology easily applicable to a large variety of building types and spread this promising technology for users.

    From CAD toiAD: An Internet application of steel construction consulting for architects
    By Zhou, Qi, Ph.D, 2002
    Abstract (Summary)
    Information technology has become so powerful and interactive that what is conventionally called CAD might evolve into iAD (Internet Aided Design). For Internet applications in the AEC (Architecture, Engineering and Construction) industry, most of the efforts and applications have been concentrated on project management and collaboration, while in the area of design and engineering consulting, limited progress has been made. Even with some of this success, contemporary development has not changed the nature of the fragmentation of the AEC industry. Based on previous research surveys of the development of Internet applications in the AEC industry and the proposal of a conceptual model of Internet-based engineering consulting in architecture, this thesis will apply these theories and concepts into a specified area of steel construction consulting for architects. The first phase of this research will define the content and scope of steel construction consulting and the potential Internet application. Second, a proposed solid working model is developed covering organizational structure, user network, services provided and technology. In the third phase, a prototype simulation is used to apply the concepts and methodology in a preliminary design application to demonstrate how this Internet-based consulting model would work.

    A Web-based approach for coordinating architectural drawings with other construction documents
    By Al-Musallam, Abed Abdullah, Ph.D., 2002
    Abstract (Summary)
    In building construction project, the process of searching for information about specific building elements in the entire different documents is a lengthy time-consuming and annoying process. This is because there has been lack of effective integration and coordination in between building elements within construction documents. This research attempts to develop a web-based approach to address this documents coordination utilizing the cutting edge computer technology. The research takes consideration the following three factors as conditions for solving this problem: (1) each member of the construction team may need different information about the same building component or element. (2) The drawings are the important key information source to start the process of searching for information about an element or a component within a building project. (3) The importance of integrating and coordinating the drawings with all other construction documents at the building components level.

    Design methodology for tall office buildings: Design measurement and integration with regional character
    By Cho, Jong-Soo, Ph.D., 2002
    Abstract (Summary)
    Tall office buildings are a rational response to a concentration of urban population growth and high cost of land. Because the usable floor areas are stacked functionally to produce a high-rise, their consequent density has also over burdened the support infrastructure of major business districts. Throughout history, large buildings have been interrelated with certain indigenous characteristics such as regional climate, culture, and religion. In addition, the evolution of technologies to control regional climate in tall office buildings in the modern age have been developed in architecture. Architecturally, this design trend causes a lack of climatic concerns, which directly affects large energy consumption and a negative ecosystem in nature. This study is based on the proposition that a design methodology can be developed to consider regional climate adaptability during the initial design process, which can simultaneously optimize energy efficiency and minimize negative ecosystem in nature. Based on analysis of current design methodology, the eQUEST energy program was used for the comparative analysis that evaluates the significant architectural design variables within several regional climates. From the statistical results, tall office buildings physically need less energy when the architectural design responds to regional climate, so that design with regional climate adaptability produces a more reasonable design and can result in a more aesthetic solution for tall office buildings that is more harmonious with nature.

    Sustainable regionalism, climate responsiveness as a regional character stimulus
    By Mansy, Khaled Abdelmonem, Ph.D., 2001
    Abstract (Summary)
    Bioclimatic design is the tool by which climate responsiveness can be achieved. The benefits associated with bioclimatic design are economic, environmental, and aesthetic; which all comply with the objectives of sustainability. Sustainability is a universal concept, yet requires unique measures when applied in different contexts. That is why sustainability can enhance regionalism. The thesis suggests a hypothesis that is: "responsiveness to local climate can stimulate creating distinct regional architectural and urban character". The approach adopted by the thesis is to explore the potential of the climate responsive architectural and urban form to stimulate a regional character. In the thesis, climate responsiveness is measured by the environmental performance of form. Environmental performance is measured by the energy use index. Can energy efficient forms play a role in creating a regional character? The thesis will try to answer this question based on the obtained sensitivity of the environmental performance of form due to change in a list of geometrical vocabulary elements, in the four world climates. Consistency of the trend in which form affects performance, in each climate, will determine the potential role of energy efficient forms to stimulate a regional character.

    A visual approach for structural analysis for architects
    By Abdelmawla, Samir Zaky, Ph.D., 2000
    Abstract (Summary)
    A major portion of an architect's education is structures. Such study of structures includes engineering concepts presented in mathematical terms and architectural design presented in non-mathematical terms. Visual representation of structural concepts is an appropriate approach to understand engineering and design. Interactive learning technique can be developed to meet the needs of architectural students, who are best suited for such visual approach.

    A study on planning and development of tall building: The exploration of planning considerations
    ByChoi,Yongsun, Ph.D.,2000
    Abstract (Summary)
    The purpose of this study is to furnish aid to persons involved with the execution of tall building by establishing useful data that could be used as criteria for development, planning and design of tall buildings. Development of tall buildings could be determined by design factors; these factors have several parameters such as sitting (site location), user needs (single & multi-function), functional requirements (space needs) and structural demands. These design parameters are dependent upon planning considerations and building systems. Items related to planning considerations are planning modules, lease spans, floor-to-floor heights, building functions, core planning and vertical transportation. Structural systems, mechanical & electrical systems, enclosure systems and building serviceability could be considered as building systems in tall building design. These considerations are interdependent with each other and they affect the overall building design.
