Ventilation Of PEB Building

Natural Ventilation:
Natural ventilation utilizes openings such as windows, louvers, or vents to allow fresh air to enter and stale air to exit the building. It relies on wind and buoyancy forces for airflow, making it energy-efficient and cost-effective.

Mechanical Ventilation:
Mechanical ventilation involves the use of fans, blowers, or ducts to control airflow within the PEB. It provides consistent air distribution and can be integrated with HVAC (Heating, Ventilation, and Air Conditioning) systems for precise temperature and humidity control.


Mixed-Mode Ventilation:
Mixed-mode ventilation combines natural and mechanical systems to optimize airflow based on external conditions and indoor air quality requirements. This approach provides flexibility and efficiency by utilizing natural ventilation when conditions permit and switching to mechanical ventilation as needed.

Exhaust Ventilation:
Exhaust ventilation systems use fans to expel stale air from the building, improving indoor air quality by removing pollutants and excess moisture. This type of ventilation is essential in industrial settings where contaminants may be present.

Cross-Ventilation:
Cross-ventilation involves creating openings on opposite sides of the building to allow air to flow through, promoting natural cooling and ventilation. It is effective in reducing indoor temperatures and enhancing comfort in large spaces like warehouses or manufacturing facilities.

Supply Ventilation:
Supply ventilation systems introduce fresh air into the building using fans or ducts. This method ensures a constant supply of outdoor air, which is particularly beneficial in tightly sealed buildings to prevent stale air buildup.

Stack Ventilation:
Stack ventilation, also known as buoyancy-driven ventilation, relies on the principle that warm air rises. It utilizes vertical shafts or chimneys to create a natural airflow, with warm air exiting at the top and cooler air drawn in at lower levels.

Heat Recovery Ventilation (HRV) / Energy Recovery Ventilation (ERV):
HRV and ERV systems recover heat or energy from outgoing air to precondition incoming air. They are efficient solutions for reducing heating and cooling loads while maintaining indoor air quality by exchanging heat and moisture between the incoming and outgoing air streams.

Spot Ventilation:
Spot ventilation systems target specific areas or rooms within the building, such as bathrooms, kitchens, or workshops. They use localized exhaust fans to remove pollutants, odors, and moisture directly from these spaces.

Wind-Driven Ventilation:
Wind-driven ventilation harnesses natural wind forces to create airflow within the building. It utilizes strategically placed openings, such as wind scoops or vents, to capture and channel prevailing winds into the building interior.
