استخدام مواد وتقنيات النانو لرفع كفاءة التشطيبات الخارجية للمباني لتحقيق جودة بيئتها الداخلية: دراسة تطبيقية على مبنى إداري

الملخص EN

Nanotechnology applications have created a comprehensive change in all lifestyles, which in turn revolutionized the field of construction materials and architectural finishes in general, and facades in particular, because facades are no longer just a secondary outer shell for the building, but rather have become one of the most important tools for the architect to express his ideas.

nanotechnology is to reach a better level of performance inside and outside the building, and despite the widespread application of nanotechnology materials in many developed countries; it has not reached the required level in the Egyptian local market, and herein lies the research problem.

the importance of the research is summarized in highlighting the importance of using Nano materials in finishing facades, especially administrative buildings, coinciding with the establishment of the new administrative capital to include many administrative buildings, as well as the state’s orientation towards sustainability through Egypt's vision 2030 to achieve a balance in the state’s resources between the present and the future, so we can use nanotechnology materials that we avoid the drawbacks of traditional building materials and finishes or improve their performance.

the research aims to use Nano materials because they have a significant impact in the field of external finishes, so they can achieve the highest efficiency in finishing facades, in addition to reducing maintenance costs, rationalizing energy consumption, achieving environmental sustainability, and achieving the quality of the internal environment for users.

to reach the above, the research is divided into two parts.

the first part follows the inductive approach and contains concepts about nanotechnology and materials and their applications in architecture and the extent of the impact and employment of Nano materials in finishing the external facades of buildings, and their capabilities in transforming the function of finishing materials into other functions that serve considerations of cost, maintenance and environmental sustainability, as well as addressing the concepts of internal environmental quality and linking it to materials finishing using nanotechnology.

as for the second part, it follows the analytical and comparative analytical approach and contains an extract of the most important results of the use of Nano materials techniques in the external facades of buildings through monitoring and documenting some modern projects globally in which different Nano materials were used in finishing their facades to determine the impact of their use in the facades of those buildings.

an existing administrative building with traditional finishing materials to make a comparative analysis between the efficiency of the facade elements of this building currently and their efficiency if they were replaced with nanotechnology materials to reach the research result and then the results and recommendations.
