(#8496) SHGC compliance for all building facades.


A project located in Mumbai has 4 towers, out of which the North façade of only one tower does not meet the SHGC requirement. Can this be ignored and the project still meet the mandatory requirement?


As a mandatory requirement, the building envelope should be compliant with SHGC requirements. Project team can demonstrate compliance by Weighted Façade average SHGC method (for each orientation) OR demonstrate compliance with Tables 9 and 10 of SP 41 to design the shading device for all the windows OR Conduct a solar path analysis for windows of AC as well as non-AC spaces, to ensure that they are completely shaded for the duration between 10:00 am on 1st April to 03:00 pm on 30th September.
