Summary.
There is a need for a suitable house design in a new desert settlements, to deal with a bad external climatic conditions which characterizes a hot dry region for achieving sustainable development of desert settlements in Egypt. So, the research attempts to apply the concept of energy efficiency to achieve the thermal comfort by using passive design methods and decreasing the use of active design methods such as air condition which increases the economical cost, in order that we depend on evaluating the elements of envelope’s parts to upgrade the house thermal performance to bound the gain of heat through the external environment. The research takes Toshky as a case study, because of its importance as the one of a great national projects which have been planned to build several residential settlements in Toshka. Aim of the Research.
The main objective of this study, is to evaluate the relative effectiveness of the elements of house’s envelope for increasing the elements` role in treat the climatic conditions. Therefore, the research is based on a calculating approach for finding the overall thermal transfer value through the wall as a applicable model to other parts of desert house envelope in Toshka. Research Structure.
The research is divided into three-parts; these are sub-divided into five chapters in addition to the lists of bibliographical material and appendices. Chapter One: Introduction. It contains the main issues that are to be dealt with in this study and its objectives, in addition to the systematic approach towards its handling. Part One: The Literature Review. It deals with the theoretical part of the research, which presents in chapter two. Chapter Two: Environmental Design of the Desert Region House. It defines the meaning of Environmental Design and its relation with conserving the Energy in desert settlements, by discussing the climatic design for house through clarifying the methods of climatic treatments to identify the role of house envelope in achieving the compatibility with climate.
Part Two: The Analytical Studies. It deals with the a calculating approach of the elements envelope role, which clarify in chapter three. Chapter Three: Thermal Design of the Envelope.
1 -ح
It studies the thermal characteristics which control the thermal transmission through theenvelope, and clarify the relation between the thermal characteristic and the architectural elements of envelope’s parts, At last this chapter presents a evaluating tool to develop the role of the elements in correcting the amount of heat aiming to achieve the concept of energy efficiency for envelope’s elements. Part Three: The Application and Results. It presents the concluding approach from the previous parts of research to identify the requisite steps which help in achieving the energy efficiency concept, and in this part we extract the conclusion and the recommendations that contact with the research. This part presents in chapter four, chapter five. Chapter Four: The Thermal Evaluating of the Wall Elements in Toshka. It identifies the Toshka region and, provides the according date with Toshka to achieving the subordinating approach in finding the overall thermal transfer value through the assuming wall. Finally, It shows the results of the relative effectiveness of the wall elements. Chapter Five: Conclusion and Recommendations.
It extracts the importance of the wall elements arrangement which belongs a high thermal performance of the wall through decreasing the heat gain from the external environment. On the other hand, It emphasizes that orientation of the wall, the area of windows, and the shading coefficient are the main wall’s elements which decrease the amount of a receiving heat from the external environment, as a example if we exchange the orientation of the wall from the east to south east, the overall thermal transfer value will decrease one hundred thousand more than the decreasing the chrome of color one degree through ten degrees from white to black. The Research recommends the following - Increasing in researches which deal the numerical evaluation for all architectural climatic methods in desert house. - Evaluating the house to know how its compatibly with the energy code, and give license to the house which achieves this compatibility by using a high-tech numerical tools for applying the codes and the standards that belongs a especial climatic region. - Providing serviceable programmers for perceiving the inhabitants with the importance of the concept energy efficiency and how to achieve this concept by non-payable consultations may be use a computer tool. Appendices.
The research contains six appendices clarify the mathematics steps of finding the relative effectiveness of the wall elements which modify the overall thermal transfer value through the wall in Toshka.
