Abstract
Adoption of new innovations in building development is something common nowadays. The aim behind these innovations is to reach increase the sustainability of the buildings by increasing their energy efficiency. Installing an external shade system in the building is considered one of these innovations. The objective of this study is to evaluate the adoption of kinetic façades that react to the external environmental conditions from some perspectives which are the daylight
performance analysis, energy efficiency, and lifecycle cost analysis. The thesis reviews the kinetic façade state-of-art as it provides a literature review about kinetic façade history, advantages, types, materials, evaluation, and implementation strategies. Also, it previews the energy consumption problem in office buildings in Egypt and the factors affecting it. The literature ends with some previous studies which investigate the development of kinetic façade, and this leads to some research gaps which needed to be covered in this thesis. The methodology that will be used in this study is parametric design method. The geometric facade design was
done using Grasshopper, while the lighting and energy analysis were done using Climate Studio. The study conducts a simulation of implementing fixed and kinetic façades into a nine-story
office building that is currently under construction in New Administrative Capital in Egypt in order to show the impact of adding these architectural innovations on responding to external
environmental factors. The study highlights the weather details and construction materials used in the case study. The design process is divided into four stages: Determining Kinetic Typology, selecting the Kinetic Mechanism, Design Kinetic Façade Control System, and Kinetic Façade Simulation. The design considerations of the kinetic façade choose Origami inspired metal type facade. The simulation consisted of three case studies: base case, fixed shade case, and kinetic façade case. The daylight and energy analysis are conducted over an annual scale and an hourly scale in August 21 and January 13 from 8.30 a.m. to 5.30 p.m. The average daylighting results show that the kinetic façade reduced the mean illuminance with respect to annual and hourly analysis. The results show that energy consumption is also reduced with a higher value in the case of kinetic facade than fixed shades. In terms of the annual cost of energy consumption,
kinetic facades are the most economical solution of the three cases. To be concluded, adoption of kinetic façades will improve energy efficiency, which will help to mitigate the effects of
global warming. Research contributes to the development of several topics for future research, the most important of which is the exploration of new formative patterns for the design of kinetic facades that allow higher energy savings through collaborative work between both energy engineers and mechanical engineers and architectural researchers. The thesis consists of six chapters as follows: Chapter1: Introduction Chapter 1 consists of a historical outlook and introduction to a research problem, scope of research, research questions, research hypotheses, research problem, research objectives,
research methodology, research determinants, and thesis structure.
Chapter 2: Literature Review In Chapter 2, the researcher addressed the common definitions of kinetic facades, the historical sequence of the use of kinetic facades, the comparison of the advantages and disadvantages of
both kinetic facades and fixed shading systems, and the environmental impact of their use on buildings, their materials and the mechanism of installation and maintenance, as well as a summary of earlier similar studies. In addition, Chapter 2 also addresses the importance of energy in Egypt and the factors affecting it. energy consumption in ASHARE office buildings. Chapter 3: Case Studies This chapter presents 18 buildings that use kinetic facades in their buildings and shows the history of their origins, kinetic system, materials used in them, movement mechanism, and
environmental performance of those facades. Chapter 4: Environmental Analysis Simulation Of 2B-3 Office Building This chapter explains the simulation tools used and compares simulation software from the oldest to the most recent. The chapter also discusses the environmental analysis stages employed, as well as the scientific approach that Diagram Illustrative used to describe the
fundamental steps of practical experimentation. In addition to showing the study’s case (office building) by offering fundamental information, site analysis, horizontal projections,
geographical position, and climatic data. Then, by comparing the findings, go over the scenarios that will be performed. The chapter also discusses the design steps of a kinetic facade, such as choosing its mechanical system and applying it to the building to begin conducting studies. Chapter 5: Results and Discussion This chapter demonstrates the results of environmental performance in terms of the availability of natural lighting throughout the year and over a daily period through a hotter and cooler day
in the year analysis to compare the actual performance of the movement facade around the time as well as the study of annual and daily energy consumption, as well as the analysis of the thermal comfort of the building through the work of the three scenarios for the building, namely: The first scenario is that no shading system is used for the building’s exterior facades - the second
is the use of fixed solar louvers, and the third is the use of a kinetic shading system. The chapter also deals with the economic aspect of the building and the life cycle of the building for ten years if a fixed shading or kinetic shading system is used. Chapter 6: Conclusions and Recommendations The last chapter presents a summary of the results that were reached during the dissertation, as well as explains the most important recommendations for each of the competent authorities, in addition to clarifying the future research that can be carried out.
