Abstract

This thesis focuses on an optimal design for a Net-Zero Energy house in the hot environment of Libya. Such work involves two main design steps. First is the design of the house body and direction based on seasonal sun height and sun East-West track (E-W Track). Second is the design of system for house heating and cooling by implementing multi- renewable energy. The first step of the design uses the sun’s heat based on summer-winter seasons. In summer, the design prevents high sun heat from entering the house by improving the house’s insulation, thus reducing cooling energy demand. In winter, the design utilizes the sun’s heat and E-W track in heating the house by allowing optimal sunlight to enter the house from the south façade by increasing the number of windows and reducing the ultimate energy required for heating. The second step of the design uses clean energy resources as the only house energy source. Several types of software are used in the house design and energy analysis including BEopt, Energy 3D, Homer, and Mat-Lab/Simulink. Safety precautions and requirements of installing the hybrid power system are carefully followed and implemented. The selected house for the design is a concrete house located in the hot environment of Tripoli, Libya. This new house design provides comfortable indoor conditions associated with a low energy consumption of ≤ 50% of a regular home, cost reduction, and environmental protection. The layout of the chapters of this thesis is chapter one: introduction, literature review, and design criteria and specifications; chapter two: house design, thermal simulation and analysis; chapter three: sizing of the hybrid power system; chapter four: electrical details and dynamic simulation of the hybrid power system; chapter five: safety issues, bus voltages, and suggestions; and chapter six: conclusions.
