Summary: Indoor thermal comfort is an important aspect of building design. The existing standards fail to consider the thermal adaptability of the human body, leading to misleading energy consumption and system sizing. To address these issues, a physiological thermal comfort model is developed to evaluate the dynamic variation of physiological parameters and occupants' thermal sensation. This model is implemented in a building energy simulation tool to propose dynamic control strategies for thermo-hygrometric parameters and heating/cooling demands, resulting in higher energy consumption but improved comfort for occupants compared to traditional set-point values.

Summary: This study compares the impact of cavity depth on the performance of a conventional double facade (DF), building-integrated photovoltaic double facade (BIPV DF), and building-integrated photovoltaic thermal double facade (BIPVT DF). The aim is to enhance the functionality of the interstitial space between the building envelope and programmed space in terms of spatial expansion and energy production. Three systems were analyzed using simulation software, and a parametric analysis was conducted by varying the cavity depth. The results showed that the conventional DF system had lower heating demands but higher cooling needs compared to the other systems, and increasing the cavity depth led to increased heating loads and decreased cooling loads.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
