Energy Efficient Configuration Or Perforated Solar Screens For Residential Desert Buildings, Rasha Arafa

Archived Theses and Dissertations

In hot arid desert environments, the solar radiation passing through windows increases the cooling loads and energy consumption of buildings. Shading of windows can reduce these loads. External perforated wooden solar screens were traditionally used for windowsâ shading. However, there is a lack in understanding their performance in a quantitative manner and unavailability of scientific means that could be used for developing new efficient designs that suit the harsh desert conditions. This thesis investigates the impact of changing screen configurations such as perforation percentage, depth, perforation openings aspect ratio and reflectivity on the energy loads, hence defining the most efficient …

Assessment Of Carbon Dioxide Emission And Its Impact On High-Rise Mixed-Use Buildings In Egypt, Ahmed Salah Hamza

Theses and Dissertations

With Egypt's vision of 2030 focusing on sustainable development with a true emphasis on Carbon Dioxide (CO₂) emission reduction in the newly built cities and high-rise buildings, efforts are exerted on various levels towards accomplishing the vision’s goals. This is achieved through multiple tools and models associated with aiding the reduction of carbon emissions, yet not a clear one was introduced for the mixed-use buildings in Egypt.

Through this work, a significant gap was identified with respect to high-rise buildings carbon emission assessment in Egypt. This was a main driving force for this work in an attempt to …

Nanoengineered Materials For Energy Conversion & Storage Applications: A Density Functional Theory Study, Ahmed Biby

Theses and Dissertations

The conventional approach for the development of novel materials has become long relative to the desired product development cycle. Thus, the sluggish pace of the development of materials within the conventional approach hinders the rapid transformation of the scientific outcomes into useful technological products. To this end, the field of hierarchical materials informatics evolved to bridge this gap. In this field, the multiscale material internal structure is considered the starting point and the core of this approach. This being said, the density functional theory (DFT) was used to generate useful materials data for the advancement of the hierarchical materials data-bases …
