The significance of ventilation systems becomes particularly evident in tightly sealed buildings where natural ventilation is limited. In these environments, mechanical ventilation ensures that air quality is maintained at a healthy level, safeguarding the well-being of occupants by preventing the build-up of harmful substances that can arise from everyday activities such as cooking, cleaning, and even breathing.

By prioritising the removal of indoor air pollutants and controlling the air exchange rate, mechanical ventilation supports a healthier and more comfortable living and working environment, underlining its indispensable role in modern building design and habitation.

The Different Types of Mechanical Ventilation Systems

Within the realm of mechanical ventilation, an array of systems are available, each tailored to meet specific requirements of building environments. The most common types encompass:

·         Exhaust-Only Ventilation

This system primarily operates by expelling indoor air to the outside, creating a negative pressure that draws in fresh air through vents or cracks in the building’s fabric. This system effectively removes pollutants and moisture from specific areas like bathrooms and kitchens.

·         Supply-Only Ventilation

In contrast to exhaust-only systems, supply-only ventilation introduces fresh outdoor air into a building, creating positive pressure. This pressure forces stale indoor air out through vents or building leaks. Supply systems are often equipped with filters to cleanse the incoming air of impurities.

·         Balanced Ventilation

These systems offer a harmonious solution by extracting indoor air and drawing in an equal amount of fresh outdoor air. This balance ensures the building maintains a neutral pressure, optimising air quality without creating drafts or unnecessary energy losses.

·         Energy Recovery Ventilation (ERV)

Sophisticated and efficient, ERV systems not only balance the intake of fresh air and the expulsion of stale air but also conserve energy by capturing heat or coolness from the outgoing air and transferring it to the incoming air, reducing the energy required to heat or cool the building.

Each system presents distinct advantages, and the choice is largely influenced by the building’s design, usage, and geographical location. This underscores the necessity of a tailored approach to mechanical ventilation.
