We investigate and test the effectiveness of a novel window windcatcher device (WWC), as means improving natural ventilation in buildings. Using ANSYS CFX, performance window-windcatcher is compared to control case (no window-windcatcher), three different geographic locations (Cardiff, Doha Amman) which are representative types atmospheric conditions. The proposed has been shown improve both th...

background and objective : a considerable amount of sulfur hexafluoride is applied to evaluate the performance of each laboratory hood according to ashrae–110-95 method. sf 6 is extremely hostile to environment and expensive. in present work, the possibility of conducting this method of hood performance test with less volume of sf 6 was investigated. material and methods : the performance of a ...

Among the many technical and tactical aspects of the behavior of players, the goals are the most studied. The goal is the key to success for teams and its analysis in all matches of a major futsal tournament (World Cup) that allows multiple assessments. The aim of this study was to analyze the impact of the first goal for the final result in the futsal match, identifying the team that scored th...

Temperatures in Mediterranean cities are rising due to the effects of climate change, with a consequent increase heat waves frequency. Recent research has shown tempering potential semi-outdoor spaces such as courtyards, which semi-enclosed that widely used by users buildings cities. International standards addressing thermal comfort parameters provide technical guidelines for indoor only. Expa...

Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win.

Heating, ventilation, and air-conditioning (HVAC) systems use the most electricity of any household appliance in residential communities. HVAC system modeling facilitates study demand response (DR) at both power levels. In this article, equivalent thermal model a reference house is proposed. Parameters for were determined based on systematic experimental data obtained from fully instrumented fi...

Occupants' thermal sensitivity influences comfort temperature, models, and building energy simulation. To date, a universal estimate (i.e. 0.5/°C), the so-called Griffiths Constant, has been widely used to temperatures. However, recent field evidence indicates that constant is actually variable changes according context. The objective of this study explore impact different values on adaptive mo...

Children differ from adults in their physiology and cognitive ability. Thus, they are extremely vulnerable to classroom thermal comfort. However, very few reviews on the comfort of primary school students available. Further, children-focused surveys have not reviewed state-of-the-art prediction using machine learning (AI/ML). Consequently, there is a need for discussion children-specific challe...
