Land is precious and it is ‘super’ precious in metro cities like Mumbai. For example, the micro space glass between façade and the wall behind it in a building is virtually a waste and cannot be used for any other purposes. Also, often you see birds getting trapped in this space which ultimately die or have to be removed after lot of efforts. However, for builders in Mumbai it is an additional opportunity to rake in some more moolah as they use glass façade material as the FSI area.
However, the new development control regulations (DCR) under Mumbai’s development plan (DP) will ensure that glass façades in city’s buildings will be a thing of past. Or at least it will discourage rampant use of glass facades in buildings in the city. According to the new DCR if builders continue to use the glass façade material, which they are barred from using, then the area between the glass façade and the wall behind it will be counted under floor space index (FSI).
The rule is primarily aimed at discouraging the builders from using glass as façade material. For example, many environmentalists and city planners have been raising their voice against rampant use of glass façade in Mumbai which has tropical climate. Glass façade are known to trap heat which will keep temperature within the building warm which in a region like Mumbai where at least 8 months in a year has warm to hot climate will result in additional energy consumption on air conditioners.
