Research Activity 

My primary research focus is to study the performance of wind towers in winter conditions. I have been working in a Wind tower integrated with a solar heating unit to meet building thermal comfort conditions. Many studies have been conducted under natural ventilation to improve Indoor Air Quality (IAQ). Most passive ventilation techniques are limited to the summer season only. The indoor humidity level is not maintained and controlled in the passive approach during winter resulting in the chance of growth of micro-organisms. Some research discusses an evaporative technique in a passive ventilation system, but it will cause some health issues in humans. The proposed project focuses on implementing a year-round capable passive ventilation technology without using any harmful chemicals. It mainly concentrates on the IAQ inside a built environment and humidity control. The system can be implemented for both cold and hot climatic conditions.
