Natural ventilation is one of the most pragmatic and efficient strategies to achieve sustainability and ecological living, especially in a modern context. Natural ventilation is a means of letting fresh outdoor air into interiors without the need for air conditioners or other mechanised devices.
The Orientation Of Windows And Doors
The orientation of a house on a site should take advantage of the favourable breezes, which vary based on region, time of day, weather, and topography. In coastal areas, breezes are onshore and in steep and hilly areas, they usually flow downslope. Whereas some coastal areas are also known for their strong winds. Based on the time of the day the cool breezes are most prevalent in the late afternoon and early evening. Outdoors, fencing and planters can help funnel breezes through a window or door while also filtering heavier winds. Therefore, for the utmost benefit, the doors and windows should be oriented to face the breeze accordingly to let the air travel inside naturally.
Choose Window Styles To Direct Or Divert Ventilation
The form and size of apertures can influence airflow patterns and the direction or diversion of air movement. Casement windows are the most conventional form of a window, having hinged frames that open inwards or outwards much like a door. When fully opened, they provide maximum ventilation and can impede airflow within when partially opened.
A louvre is a simple rectangular glass panel which can pivot open to allow circulation. Louvre windows feature a sequence of these panels, and how much they are opened affects the amount of breeze that may enter a space. Louvre windows too can be fully or partially opened and closed to change ventilation routes and adjust airflow.
Install Apertures For Cross Ventilation
While people may believe that wind passes through a structure, it is actually trapped in low-pressure zones. As a result, openings that allow breezes to pass through should be constructed. Hence, it is necessary to install cross-ventilation openings on at least two sides of a room, either opposite or adjacent walls. Courtyards also allow for cross ventilation through the house. Further to that, while not all houses these days allow for optimal natural ventilation, it is a win-win situation if artificial ventilation systems (AC) can be well integrated alongside natural ventilation.
Install Automatic Natural Ventilation Systems
Automatic ventilation systems can open and close windows in response to indoor temperature changes. This permits ventilation inside while releasing and regulating heat - extremely beneficial if you are away all day. An automatic system can contribute to reducing overheating in homes with wide expanses of northern glazing.
Promote Air Circulation By Convection
Temperature differences are used in convective ventilation, also known as stack ventilation. Warm air is more buoyant, so it rises to exit through higher openings, drawing cooler air in from lower ones. Clerestory windows, operable skylights, roof ventilators, and vented ridges all function on the principle of convective air circulation to potentially maximize cross ventilation.
Reap The Benefits Of The Night Breeze
Houses often cool at night when heated air from a building is replaced by the cooler night air. Keeping windows open at night will assist in purging heated air and ventilating interior spaces for the upcoming day. Double-hung and clerestory windows are appropriate in this case since hot air exits through higher-level apertures.
Add Screen Blocks To The Facade
Screen blocks on the facades are one of the most effective ways of allowing not only ventilation but also natural daylight and some visual permeability. Several prototypes and specific opening systems are necessary for the development of this component. In addition to providing visual insulation and enabling natural light and ventilation, are also implemented as room dividers, lending a different character to the whole project. Additionally, when establishing a new structure, the connections between the facade and the interior can be created from the ground up.
Elements Of Water
Water plays an essential role in many Indian landscapes and housing designs. Transitional spaces such as fountains, pools, and swimming pools can be used to cool the air before it passes through the interiors.
Groundcovers
Cover pavements and adjacent areas with grass or other heat-resistant materials. By utilising grass, the amount of heat absorbed by the ground is reduced significantly. This considerably aids in the distribution of cold air within a home or structure.
Wicker Or Bamboo Furnishings
Because of their lightweight and minimal heat retention, these materials can stimulate good air circulation. Wicker and bamboo perform excellently both indoors and outdoors.
Transitional Elements
Integrate courtyards, balconies, gardens, and other open spaces to enhance air circulation. In this era of strategic planning, creating a suitable transition zone from indoors to outdoors might feel like a piece of heaven for inhabitants with access to fresh air. Additionally, a transitional space can aid with air circulation by providing optimal ventilation.
Natural Ventilation In Homes Following Pandemic
Architects have been concentrating on the necessity for better natural ventilation and concern for indoor air quality as a consequence of increasing attention to healthier interior spaces due to COVID-19. Larger apertures such as windows, doors, and skylights help provide the demand for natural ventilation indoors. Adding a larger window or door tends to be associated with boosting daylighting and wellbeing, and also enhancing the effectiveness of the home, which is now regarded as a retreat.
Natural ventilation has numerous benefits. Chemical substances discharged into the air by air conditioners or other mechanical equipment are reduced, and energy expenses are considerably cut. Ultimately, natural ventilation in homes can benefit the inhabitants, the building, and the environment.
