Summary: The study evaluated a two-sided windcatcher incorporated with an upper wing wall through wind tunnel testing and CFD modeling, finding that increasing the upper wing wall length can slightly increase ventilation rates, with the best performance seen in the 50 cm configuration. Results showed that even at lower wind speeds, the windcatcher can still meet IAQ parameters, and wind speeds from 2.5-4 m/s can achieve 50%-80% thermal comfort.

Summary: Students' performance in Sudan is negatively affected by poor indoor environments. To improve the education system with limited budgets, the local government in Khartoum and the Ministry of Education have launched a joint project to construct new school buildings with unified prototype models. The new passive wall system evaluated in this paper effectively reduces indoor air temperatures and is environmentally friendly, making it attractive for the education sector in Sudan.

Summary: This paper examines the effectiveness of selective passive measures in church buildings, aiming to protect the macroclimate and achieve a sustainable and comfortable indoor environment. The results show that certain passive measures can alleviate severe indoor temperature fluctuations, creating a more comfortable environment. However, environmental control presents conservation challenges. Historic church buildings, designed with passive features for internal comfort, outperform expectations and more contemporary structures overall.

Summary: The global debate on immense energy consumption, natural resources depletion, and high levels of Green House Emissions (GHG) increasingly emphasizes the need to derive sustainable building solutions from local vernacular architecture. However, limited research has been conducted on this issue in arid hot regions, especially in the Arabian Peninsula. This study contributes to the debate by evaluating the sustainable features and thermal comfort and energy performance of Omani vernacular houses. The study combines on-site measurements and modelling simulations using DesignBuilder software to achieve the objectives of characterizing vernacular architecture in Oman, evaluating the thermal and energy performance of a selected vernacular house, and comparing it with a contemporary Omani house. The numerical simulation confirms that the vernacular construction system provides enhanced thermal performance and requires significantly less cooling energy compared to the modern counterpart.

Summary: Increasing thermal mass and activating night ventilation can effectively reduce peak temperatures during a heat wave, while closing external blinds can help stabilize indoor temperatures. However, the activation of night ventilation may increase diurnal temperature variations, especially in lightweight construction.

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.

Summary: This research introduces an innovative resilient design framework that optimizes building performance by considering a holistic life cycle perspective and accounting for climate projection uncertainties. The study finds that future climate scenarios significantly impact building life cycle performance, with wall U-value, windows U-value, and wall density being major factors. By using ensemble learning and optimization algorithms, predictions for carbon emissions, cost, and indoor discomfort hours can be made, and the best resilient design scheme can be selected. Applying this framework leads to significant improvements in building life cycle performance.
