“…The outcomes demonstrated that wind flow has numerous favourable circumstances, including an agreeable and healthy indoor condition and sparing energy by methods of passive cooling or natural ventilation. Likewise, an examination utilizing Fluent CFD programming was directed by Song and Meng [5] to improve ventilation execution in a study hall. In light of the simulation data, it is discovered that double rows windows can improve the thermal comfort conditions most effectively, thus exhaust fans and ceiling fans, however, ceiling fans could improve the environment of occupied zones better.…”

“…For all the explored cases, the distributions of Cp on all walls of the mosque model, alluding to Figure 9, are appeared in Table 3, which incorporates the distributions of the Cp just as well as velocity vectors for various inlet air velocities (3,5,10,15, and 20 m/s). Likewise, the comparison with experimental results, at the available velocity of 20 m/s, is shown in Table 3.…”

Sultan Al-Ashraf Qaytbay mosque is viewed as one of the most beautiful achieved landmarks of late Egyptian Mamluk architecture. The mosque architectural design is considered exceptional for its refined extents and the subdued yet exquisite decorations. In this paper, Computational fluid dynamics (CFD) simulation joined with wind tunnel experiments are performed to investigate the airflow characteristics inside the mosque of Sultan Al-Ashraf Qaytbay due to natural ventilation brought about by window openings. Wind tunnel experiments are performed to provide the boundary conditions for the subsequent CFD simulations. The results of CFD simulation are contrasted with that of the wind tunnel experiments. The comparison demonstrates great agreement between the computational and experimental results, which confirms the legitimacy of the present computational procedure. Interesting outcomes and productive conclusions are inferred from the obtained results.

The aim of the paper was to verify whether it is possible to predict thermal indoor environment in an industrial facility, characterized by large cubature and significant heat sources using a computational fluid dynamics (CFD) technique. For this purpose, thermal imaging measurements were carried out to obtain boundary conditions, followed by numerical simulations of the airflow using the Ansys CFX software. Direct results of temperature and velocity distribution of air were analyzed for two different cases. The possibility of reducing the supply airflow rate without affecting either technology safety or thermal comfort was examined. The results of calculations can be helpful for improving the energy efficiency of the tested object by indicating the optimal operating modes for given operating conditions of the production hall.

Any operation addressing historical buildings refurbishment and plant system retrofitting is a complex task. Here we propose a methodological approach for achieving efficient, sustainable energy solutions guarantying objectives of conservation and preventive protection of the Cultural Heritage as well as Indoor Air Quality (IAQ) and thermal comfort for the users. As a consequence, all the related operations should be efficient and effective, in compliance with required indoor thermo-hygrometric conditions, ventilation, air quality and user wellbeing. La Montagnola primary school in Florence, designed by the architect Francesco Tiezzi and built between 1958 and 1963 is the case study. Dynamic simulations specifically addressed to control and adaptive proportional regulation of the building-plant system. Results showed that refurbishment and retrofitting operations on the plant system led to more significant energy saving in comparison with that obtained only with interventions on building envelope, mainly under constraints imposed by the National Heritage Protection Offices (Soprintendenza). Results assessment highlighted the fact that the use of dynamic simulation and CFD techniques, and consideration of thermal comfort at an early design stage, allowed the identification of design solutions combining energy saving with internal comfort, health and safety during throughout the school year.
