Window Design for Natural Ventilation – Tropical Region

Natural ventilation considerations for radon prone areas of Ramsar

Background: In Iran, architectures are often unaware of the risk of radon inhalation and how to reduce radon levels. Furthermore, radon considerations are not implemented in construction methods, construction materials and building utilization by regulatory authorities. Materials and Methods: In this study after reviewing the meteorological changes of Ramsar over the past 50 years (1955-2005), ...

Window Design in Ardabil Traditional Houses for Conservation of Energy

Providing Design Strategies for Ventilation System in Treatment Environments (Proposed Sample: Hybrid Ventilation System in Hospitals)

One of basic principles in designing treatment environments is to design air conditioning/ventilation system proportionate to environment. Essentially, appropriate air conditioner in treatment spaces must bear the following capabilities: providing healthy and clean air, reducing the concentration of pollutants produced in the atmosphere, emission of pollutants and impeding their spread in exter...

Design an optimized model to improve natural ventilation thorough the roof orientation

Natural ventilation is among those effective methods that is useful in hot dry climates. One of its important uses is in the atrium spaces in the office buildings. Although, as a passive solution, it has a significant impact on the reduction of energy consumption, the control of inlet and outflow of air as well as the control of air current temperature has always been a challenge for architects...

A Ventilation Index for Tropical Cyclones

A number of environmental factors control both tropical cyclogenesis and tropical cyclone (TC) intensity, contributing to the challenge of TC prediction. Among these environmental controls is the interaction of TCs with environmental vertical wind shear. Since environmental vertical wind shear is always present in varying amounts during the life of any TC, it is important to understand how wind...
