“…Their output depends heavily on factors like temperature, solar radiation, and wind speed. In this scenario, while balancing renewable energy sources at building scale with micro-gird and energy grid is a well-established scenario [18][19][20], the smart component with IoT embedded in building' products address self-powered solutions adopting energy harvesting [21][22][23]. In this context, the role of active module to provide building envelopes with copiabilities is a path of research widely researched within smart building component [24][25][26][27] and the role of energy harvesting can boost their adoption.…”

This paper presents a study about the integration of Piezoelectric Energy Harvesting Systems (PE-EHS) in building envelopes for powering Fiber Bragg Grating (FBG) sensors, enabling efficient and low-consumption monitoring with the objective to leverage Structural Health Monitoring (SHM). The research includes preliminary tests conducted in a real environment to validate the PE-EHS when fully integrated into the façade, capturing mechanical vibrations generated mainly by wind loads. Based on these activities, the final configuration of PE-EHS is defined to provide a complete system for façade monitoring. This integrated system includes the Piezoelectric Generator (PEG), Supercapacitor (SC), Power Conditioner Circuit (PCC), Fibre Optic Sensing (FOS) Interrogator, and the IoT Gateway trans-mitting measurement data within an Internet of Things (IoT) monitoring platform. This configuration is tailored to address the challenges related to the structural integrity of building envelopes. Results demonstrate a potential for a stand-alone solution in the façade sector, but, raising issues for certain limitations, requiring further investigation. In particular, the study emphasizes constraints related to the energy production of PE-EHS for façade integration. It highlights the necessity to carefully consider these limitations within the broader context of their applicability, providing insights for the informed deployment of Piezoelectric Energy Harvesting technology in building envelope monitoring.

One of the key approaches to achieving an optimal balance between energy consumption and overall comfort in existing buildings lies in the use of sophisticated simulations for efficient management of HVAC systems. Modeling and simulating the energy performance of buildings represent a highly advanced technique that enables the predic-tion of complex system behaviors based on physical laws and principles. These simulations allow for precise solving of thermal equilibrium equations, taking into account all essential physical characteristics of the building, the com-plexity of the mechanical systems serving it, as well as a wide range of dynamic input variables throughout the entire calendar cycle. Critical factors significantly influencing energy consumption in buildings are region-specific climatic condi-tions, as well as individual user expectations regarding indoor temperature, humidity, and air quality. The methodology of this advanced research is based on the use of the state-of-the-art simulation tool Ener-gyPlus, which enables a detailed analysis of the building's energy performance. This holistic approach enables the enhancement of energy efficiency in existing buildings and optimization of HVAC system operation, resulting in significant energy savings and improved overall user comfort. Furthermore, this study aims to demonstrate the improvement of building systems themselves to achieve nZEB buildings and the utiliza-tion of renewable energy sources. The work is expected to use simulations of the model, along with additional systems, to minimize the net site en-ergy through PV panel-integrated systems compared to the model without such systems. The results obtained from the baseline model already demonstrate low energy requirements, while the use of PV panels is expected to result in even lower consumption. The total energy required to meet the building's energy needs is 41,109.67 kWh, which translates to 36.41 kWh/m² of the total building area. The paper will also demonstrate a reduction in CO2 emissions compared to the model without PV panel-integrated systems.
