Window-Windcatcher for Enhanced Thermal Comfort, Natural Ventilation and Reduced COVID-19 Transmission

Adaptive Thermal Comfort and Ventilation

Thermal Comfort in Offices – Natural Ventilation vs. Air Conditioning

Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-condit...

COVID-19: A Window of Opportunity for Positive Healthcare Reforms

The current coronavirus disease 2019 (COVID-19) pandemic is testing healthcare systems like never before and all efforts are now being put into controlling the COVID-19 crisis. We witness increasing morbidity, delivery systems that sometimes are on the brink of collapse, and some shameless rent seeking. However, besides all the challenges, there are also possibilities t...

Mathematical Model of Novel COVID-19 and Its Transmission Dynamics

In this paper, we formulated a dynamical model of COVID-19 to describe the transmission dynamics of the disease. The well possedness of the formulated model equations was proved. Both local and global stability of the disease free equilibrium and endemic equilibrium point of the model equation was established using basic reproduction number. The results show that, if the basic reproduction numb...

Design with Nature: Windcatcher as a Paradigm of Natural Ventilation Device in Buildings

The traditional architecture of Central Asia and the Middle East is the product of land, the local climate, and people’s culture. The human needs and the environment represented the most essential factors to be considered in their designs. The traditional and vernacular architecture of this region introduced many realistic solutions and devices to the local environmental problems such as the Wi...
