Description In a world increasingly focused on sustainability and energy efficiency, Zero Energy Buildings (ZEBs) have emerged as a prominent concept. However, the definition of a ZEB remains a subject of debate and controversy. This thesis seeks to unravel the complexities surrounding the definition of ZEBs and explore new frameworks that can better guide the design and evaluation of high-energy performing buildings or districts. The research will focus on redefining the physical boundary of analysis, developing a robust weighting system method for assessing different energy flows (primary energy) and refining the timestep of analysis, all within the context of the European Union's urgent call for zero-emission or carbon-neutral buildings.
The primary objectives of this thesis are as follows:
1. Evaluate the Current Definition of ZEBs: A critical examination of the existing definitions of Zero Energy Buildings will be conducted, including their inherent limitations and ambiguities. This evaluation will serve as a foundation for proposing a more comprehensive definition that aligns with the European Union's sustainability goals.
2. Propose an Enhanced Definition and a numerical methodology: Based on the results of the initial assessment, this thesis will propose an updated and comprehensive definition of Zero Energy Buildings aligned with the European Union's call for carbon-neutral buildings, rethinking the physical perimeter of the analysis, the weighting system and the analysis timestep.
3. Case Study Analysis: A real-world case study will be conducted to apply the proposed methodology, demonstrating its practicality and effectiveness in assessing high-energy performing buildings or districts.
4. Results and Discussion: The thesis will present the results of the case study analysis, along with a comprehensive discussion of the findings. It will shed light on the advantages and challenges of the proposed framework.
