Energy conservation is a major concern today around the world and there has been an increasing focus on energy efficiency over the last few decades. Making buildings energy efficient for the promotion of sustainable growth and development is something that the entire world is harping on. By making slight adjustments and improvements in the insulation and temperature controls, buildings can be made for environment friendly. It is reported that about 60% of the energy used is due to the heating and ventilation of buildings.
There are two types of ventilation systems that work in order to remove unwanted polluted particles from inside the building and replace it with fresh air – natural and mechanical. In order to reduce the carbon footprint, it is expected that natural ventilation is going to play a major role in the coming years but before coming to any conclusion, let us take a look a closer look at both the ventilation systems.
Natural Ventilation VS Mechanical Ventilation
a. Natural ventilation can occur through air infiltration from doors, windows or cracks and it lacks a controlled, mechanical process that ensures that a building is properly ventilated. Whereas, mechanical ventilation allows you to control the airflow and ensure that a space receives the needed amount of ventilation. Modern systems in fact are engineered to automatically control the airflow and maintain a balance. For instance, in car parking spaces, it is not possible to have windows and doors because these are usually below the basement level. Natural ventilation is not an option!
b. For various security and privacy reasons, natural ventilation ceases to even be an option. But with advances in mechanical ventilation systems such as ductless systems, it does not take up a lot of space and can properly ventilate a space while adhering to the highest standards of quality and does not harm the environment in any way as well.
c. No energy is consumed when a space is naturally ventilated. On the other hand, mechanical ventilation does make use of certain amount of energy but due to technological advances, even ductless ventilation systems have become energy efficient and it does not add to the carbon footprint but work towards reducing it.
d. In case of fire, natural ventilation is not going to do much good since it will not be able to eradicate the smoke fast enough for people to evacuate the space. But as for mechanical ventilation systems, they are built and designed to function is distress situations and increase airflow to get rid of the smoke.
e. Natural ventilation cannot regulate the thermal comfort of a space based on real-time measurement of internal and external temperature and pollutants but mechanical ventilation systems can. They can detect when the pollutant level is high and balance it out evenly.
To sum it up, natural ventilation is not really predictable whereas mechanical ventilation is in your hands and you can control the environment according to your requirements. By opting for advanced ductless ventilation systems, you can not only find the perfect ventilation solution for your space but you can also contribute towards a sustainable growth.
