Where are the ventilation buildings on the Battery Tunnel?

There are four ventilation buildings on the Brooklyn-Battery Tunnel: two in Manhattan, one in Brooklyn, and one on Governors Island. Due to objections to the building's design throughout the construction process, one of the Manhattan ventilation structures is granite-faced and fashioned like a memorial. The other has been called New York City's first "green" building because it uses solar power and natural air flow to control its temperature.

The Brooklyn structure is an 8-story brick building with a steel frame that was constructed in 1872. It was originally used for storing grain but now houses offices and storage space. The Governors Island building is a 7-story brick structure built in 1917 to replace an earlier wooden building. It provides relief for workers on the tunnel project by allowing them to escape from the heat and humidity of underground construction sites.

Both the Manhattan and Brooklyn structures have roof gardens that provide fresh air to the buildings during hot summers. The roofs of both structures host hundreds of species of plants, including trees, flowers, and shrubs. They are also home to animals such as birds, insects, and small mammals.

The ventilation buildings were important additions to urban life in the Gilded Age when cities were struggling with pollution issues. At the time, factories produced much of the city's smoke and gas emissions illegally through open windows or doors, so citizens needed places where they could get some fresh air.

What is the Metro ventilation shaft?

The ventilation shaft, which is 43.5m deep, was built in collaboration between the Kolkata Metro Rail Corporation (KMRC) and Afcons, a private engineering firm. Such shafts are utilized not just to give ventilation to the tunnels, but also for emergency escape. These shafts were originally used by the Indian Army for underground warfare.

In addition to this, there are several other ventilation shafts under construction or already operational on various parts of the Metro system. Some of these include: one at Jaydev Park station for use as an evacuation route in case of fire; another at Burrabazar station for the same purpose; and the third at BNR South Station for use as an air-raid shelter. There is also a ventilation shaft at Sealdah North station, but it is only accessible from the outside of the building through a manhole cover.

Ventilation shafts can be seen across India in many cities including Delhi, Mumbai, Chennai, Bangalore, and Hyderabad. They provide essential fresh air into buildings and help remove noxious gases such as ammonia from factories.

Why do buildings have air shafts?

Ventilation shafts, also known as airshafts or vent shafts in subterranean civil engineering, are vertical channels used in mines and tunnels to convey fresh air below and remove stale air. A building's floor plan with an airshaft is sometimes described as a "square doughnut" form. The airshaft allows the ventilation of one room while keeping other rooms closed off from it.

As well as being useful for ventilation, airshafts can also be used for plumbing or heating if suitable pipes or ducts are laid inside them. These are often called "hidden" or "internal" airshafts.

The word "airshaft" comes from the Latin airius, meaning "fresh."

In architecture, an airshaft is a passage that provides ventilation to lower-level rooms where there is no access to natural light or fresh air. It may be above ground, under the floor, or within a wall. In buildings with many floors, airshafts are usually located on each floor between that floor and the floor below it. They provide emergency escape routes in the event of fire or other emergencies.

People living in high-rise apartments often complain about the noise coming from the airshafts next door. But this is just part of the sound barrier that separates adjacent apartments. There is nothing that can be done about these noises except by moving into another apartment.
