Today's homes are constructed to be energy-efficient but many of them experience poor indoor air quality. Efficient ventilation is necessary to keep clean healthy air. Ventilation is the circulation of air by which fresh air or outdoor air gets into space in that way keeps the room comfortable with clean by removing pollutants.
Proper ventilation provides a refreshingly healthy and safe working environment by removing air contaminants and it works best for reducing heat buildup in the home. Ventilation is an energy-efficient and low-cost way to cool the home. There are two options for removing polluted hot air and allowing fresh air from the outside: mechanical ventilation and passive ventilation. Unlike mechanical ventilation, passive ventilation doesn’t need electricity. Thus it is an inexpensive and energy-efficient method of ventilation. Fresh air is drawn into the house because of the temperature differences in indoor and outdoor air. Low-temperature fresh air forces warm polluted air towards the outside. Two types of passive ventilations are cross and stack.
Stack ventilation
Because of the low density of warm air, an opening at the top will allow warm air to escape, while an opening at the bottom allows cold, dense air to enter. When raising warm air is not allowed to escape it could be diverted all around the house. In that way, the stack effect can also be used to heat a space.
Cross ventilation
It is also called wind-induced ventilation. Because cross ventilation depends on the wind. Cross ventilation is a type of horizontal ventilation that allows air to enter a building by one side and exit through the other. Windows are the most common openings that allow cross ventilation. This type of ventilation works well practically anywhere in any climate. It is an energy-efficient, inexpensive method of cooling. There aren’t any operating costs and air pollution by the emission of carbon as mechanical ventilation systems. The less we rely on mechanical systems, the more energy savings we may achieve.
Importance of Landscaping for energy-efficient building
Trees and shrubs around your home can create 9°F cooler than the surrounding air temperature through a process known as evaporative cooling. Because they release significant quantities of water from the pores in their leaves. Around your home, grow some large, shade-casting plants.
Energy-efficient housekeeping will lead the home more comfortable and less expensive. It will also add environmental advantages over the financial benefits
