    Design Tool for a Ground-Coupled Ventilation System
    Alfadil, Mohammad Omar (Virginia Tech, 2019-04-26)
    Ground-coupled ventilation (GCV) is a system that exchanges heat with the soil. Because ground temperatures are relatively higher during the cold season and lower during the hot season, the system takes advantage of this natural phenomenon. This research focused on designing a ground-coupled ventilation system evaluation tool of many factors that affect system performance. The tool predicts the performance of GCV system design based on the GCV system design parameters including the location of the system, pipe length, pipe depth, pipe diameter, soil type, number of pipes, volume flow rate, and bypass system. The tool uses regression equations created from many GCV system design simulation data using Autodesk Computational Fluid Dynamics software. As a result, this tool helps users choose the most suitable GCV system design by comparing multiple GCV systems' design performances and allows them to save time, money, and effort.

    A Villa in Shaqra City, Saudi Arabia
    Alfadil, Mohammad Omar (Virginia Tech, 2013-06-13)
    This thesis aims to establish a context of the relationship between internal and external elements of a villa in Shaqra, Saudi Arabia. The study tends to represent the surrounding environment through the use of local and readily available building materials, rammed earth, in constructing the structural building walls. The walls of the villa designed to be built with the rammed earth, as they seem they grow out of the ground and belong to the ground, in which it has the same soul and character of the surrounding area.
