    |

I work for a property developer in Vietnam.
Our architect has proposed that we include 4 light/natural ventilation shafts (3.5m x 4m each) in the floor plate which are to run the entire height of the apartment building (i.e. 100m including basement parking). Within the shaft will be windows which are to provide natural ventilation/light to the toilets, kitchens and bathrooms.
I'm concerned that it presents a fire hazard, it will not ventilate adequately without mechanical assistance, natural light will be limited to the upper floors only (except at midday, if we are lucky) and will be a management nightmare to maintain. Our architect assures my company that this system is commonly applied in France.
Does anyone know of a building that has incorporated this type of ventilation/lighting system and it has worked? Any comments on the proposed shaft design would be useful as well.

What is your country's code regarding the natural ventilation shaft? Any? My following may not 100% accurate, just for your reference:
This shaft size 3.5mx4m is rather large, 4x3.5x4= 64 Squre Meter. How big is your building plan? Since It provides light to the bathroom and kitchen too. The big problem is how to maintain this light well clean in the bottom.
This design happened in cities in southern china in 80's. HK also used this strategy, but it is long time ago( I didn't know when it was not permitted again). Generally speaking, it is not a good design, as you said, your company will have alot of hassel to maintain this building. If you could, don't use this plan, otherwise, this building will be out of date in 10 years. China is an example. Why not ask your architect to check some example in china/HK? The climate is pretty similar.

Thanks for the valuable feedback.
There is a Vietnamese Code, however, the British Building Code is generally adopted by default for international standard developments.
The shafts are all separate. The floor plate is approx 1200 m2 and each shaft (3.5 x 4m) is separate from the other. See the attached attached plan.[/img]
