Natural Ventilation System for Passive Cooling in Buildings

Windtower-1.jpg

Our innovative technology (innovated wind tower) for natural ventilation and passive cooling focuses on temperature control and heat reduction in residential and commercial buildings (e.g., school buildings and store retailers) to provide thermal comfort for inhabitants and customers with Zero Grid Electricity.

Optimized energy consumption and thermal comfort for inhabitants are important factors in buildings design. Nowadays, air conditioning systems have a significant share in consuming electrical energy in residential and commercial buildings. Passive cooling systems, such as wind towers, can help to reduce energy use in buildings and at the same time diminish greenhouse gas (GHG) emissions. Wind towers can naturally ventilate buildings as well as create enhanced thermal comfort for inhabitants throughout the warm months.

Our innovative wind tower design is a practical solution to provide natural ventilation and passive cooling in residential and commercial buildings (e.g., school buildings and store retailers) in order to control temperature and decrease heat during the summer months. The innovated wind tower has the following important specifications: simple design and manufacturing; easy installation and usage; high efficiency by capturing maximum available wind; no electricity needed from grid; no-noise; and sustainable technology.

An example for the use of innovated wind tower is store retailers. It is estimated that approximately 20% of energy consumption in store retailers in Ontario, Canada is for HVAC systems. The use of our innovative technology can create a more comfortable shopping experience for customers as well as help to keep food product quality and reduce costs. Due to the large number of these retail stores in North America, by using this innovated wind tower, they can significantly help to reduce GHG emissions and environmental pollution (especially CO2 emissions) associated with conventional air conditioning systems.

Our innovative design can be used as a green architectural component in new residential and commercial buildings.
