Summary: The main objective of this study is to investigate the airflow patterns in single-sided ventilation of isolated buildings, focusing on buildings with two openings located at the front or back external wall. The study utilized Large Eddy Simulation (LES) with particle tracking technique to validate the airflow patterns. The results showed the influence of pulsation flow and eddy penetration in single-sided ventilation, and there was a difference between the airflow rate and purging flow rate due to the high probability of short indoor travel distance and residence time caused by eddies and pulsation flow.

Summary: The increasing demand for energy in buildings has led to a greater focus on sustainable energy sources and technologies. Wind-catchers, a type of natural ventilation system, have gained significant attention. This study proposed a new design for a wind-catcher with single-stage direct-air evaporative cooling for indoor air conditioning. Through computational fluid dynamics simulations, the effects of inclining the bottom surface and installing a baffle on air temperature drop, water mass fraction, and air velocity distribution were examined. The results showed that the inclined bottom surface improved flow uniformity in the room, while the baffled wind-catcher with different angles exhibited different flow patterns and thermal comforts. The study also proposed a methodology for evaluating the thermal comfort performance of evaporative cooling systems integrated into natural or passive cooling devices.

Summary: This article investigates the effect of turbulent onset flows on building ventilation through wind tunnel experiments and analytical modeling. The results suggest that mean flows can serve as an important indicator for designing ventilation. Unsteady analyses should be considered when building openings face indirect wind streams and when both a windcatcher opening and an opened window are present. Furthermore, the room window plays a crucial role in defining the performance of windcatcher ventilation systems and dominating interior flow behavior.

Summary: This study presents a novel humidity pump that uses metal-organic frameworks as desiccant layers to efficiently transport moisture from a low-humidity space to a high-humidity one. The MIL-100(Fe) based humidity pump showed significantly higher dehumidification rate and moisture removal efficiency compared to the silica gel coating humidity pump, with a maximum dehumidification coefficient of performance reaching approximately 0.46. The localized humidity management ability of the designed humidity pump using MIL-100(Fe) was validated by a small chamber test, showing energy-efficient localized moisture control.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.

Summary: This paper compares two main approaches to consider uncertainties in model predictive control (MPC) for buildings: robust and stochastic MPC. The results show that compared to a deterministic MPC, the robust MPC increases the electricity cost while providing complete temperature constraint satisfaction, while the stochastic MPC slightly increases the electricity cost but fulfills the thermal comfort requirements.
