A CFD software called VORTEX is used as a tool to simulate air flow and thermal comfort in naturally wind ventilated classrooms of an educational institution, which are at different locations, have different configurations and slightly differing outdoor environmental conditions. Simulations of...

Numerous studies have been conducted to explore the potential usage of natural ventilation in buildings. However, this issue has not yet been effectively resolved due to the inconsistency of air flow patterns and the extent of the parameters involved in the studies. This paper aims to identify...

This study is based on the analysis of the data obtained through a yearlong thermal comfort survey in one of the even naturally ventilated buildings in Oxford. It is concerned with how much the use of available controls contributes to thermal comfort by modifying the indoor thermal environment....

The main aim of the study is to investigate passive cooling performance in traditional urban contexts in the hot humid climate of the city of Dubai. Three cases were simulated for Al-Ras area with laminar and turbulent wind flow depending on Computational Fluid Dynamics (CFD) methodology. The...

The paper discusses the possibility of offering thermal comfort, without inducing mechanical energy cost, in new habitations, built in European style and situated in a hot and humid climate, by means of a construction element: the Roof Solar Collector (RSC), which is made by using concrete...

The main aim of the study is to investigate passive cooling performance in modern urban contexts in the hot humid climate of the city of Dubai. Three cases were simulated for Al-Mankhool area with laminar and turbulent windflow depending on Computational Fluid Dynamics (CFD) methodology. The...

The aim of this paper is to identify which method to assess thermal comfort is the most appropriate to be used in hybrid commercial buildings located in hot and humid summer climate. Three methods to assess thermal comfort were analysed: (1) ASHRAE 55 for determining acceptable thermal...

Two new designs of wind towers were tested side by side with a conventional wind tower in the city of Yazd, Iran. All the towers were of identical dimensions. The two new designs were one with wetted column, consisting of wetted curtains hung in the tower column, and the other one with wetted...

Wind towers for passive evaporative cooling offer real opportunity for improving the ambient comfort conditions in building whilst reducing the energy consumption of air-conditioning systems.

Now a day's refrigerators are very essential parts of human life and cannot sustain our life without these. But these became more commercial so that simple solar power refrigerators working on evaporative cooling principle are essential. These Solar-powered refrigerators are able to keep...
