Sustainable Mega Buildings

The study aims to develop a critical position on current research and practices in sustainable design for mega-buildings. It also proposes innovative hypotheses when appropriate. An appropriate architectural approach is formulated and articulated through a thorough analysis of theoretical and methodological perspectives in sustainable mega-building design. The study critically evaluates and interprets its own ideas as well as the work of others, generating modified conceptions. It incorporates a coherent understanding of interrelated issues in design proposals, considering climatic and sociocultural contexts, occupancy, material usage, façade tectonics, structure, construction techniques, building services, and performance of mega-buildings. Personal learning needs are identified and managed, with a focus on advancing knowledge and understanding through independent learning approaches.

The design proposal is presented in an effective and professional manner, utilizing both visual and verbal communication techniques. The study also focuses on delivering high levels of occupant comfort while minimizing energy consumption for heating and cooling. A primary energy load optimization of 44% has been implemented in the building, demonstrating the improvements made during the structure fabric optimization phase. HVAC systems, renewable heat pumps, mix mode ventilation, lighting strategies, and renewable energy sources have been incorporated, resulting in a significant impact on reducing carbon emissions. The achieved energy performance falls below the Passivhaus primary energy standard of 120 kWh/sq m. The optimal energy use and other parameters that contribute to carbon emission reduction represent important milestones toward achieving net-zero buildings. This research and its findings contribute to the advancement of sustainable design practices for mega-buildings, offering insights into improved energy efficiency and occupant comfort.
