The uncontrolled air movement through the cracks and small holes of a home is called Natural Ventilation. Previously, it was almost impossible to prevent the air pollutants entering through these holes. Modern technology has made it possible to effectively seal those holes and maintain an energy-efficient and less polluted environment inside a home. However, natural ventilation is necessary in a home and one can have that by opening windows and doors.
It is the method of removing indoor air pollution and/or moisture at its source to improve the effectiveness of natural and whole house ventilation. In this ventilation method, localized exhaust fans are used. The recommended intermittent or continuous ventilation rates for bathrooms of 50 or 20 cubic feet per minuteand kitchens of 100 or 25 cubic feet per minute, respectively.
The objective behind whole-house ventilation is encouraged by the fact that natural ventilation and spot ventilation cannot provide adequate air quality. This ventilation system uses one or more fans and duct systems to exhaust stale air and/or supply fresh air to the house. Hence, it somehow provides controlled, uniform ventilation throughout a house.
The best ways to keep your home cool during hot days are keeping the outdoor heat outside, avoiding heat-generating activities, and using spot ventilation.
Use microwave, cook on the stovetop, and use spot ventilation to avoid the heat of cooking. Also, cook outside to avoid the generation of heat inside your house.
Moreover, avoid any kind of heat generating activity such as running a computer, burning open flames, running a dishwasher, etc.
