We are assessing the feasibility of GRIHA criterion 11 for Airport building and as per the criterion at least 25% (or more) of total living area of project meets daylight factor requirements of SP 41. So the spaces like VIP lounge, boarding/ check in counters, or arrival lobby are not mentioned in SP 41. Is there any other classification under which these spaces are considered if not airport/ transit spaces?
Please consider DF values as follows from SP-41 for airports
Common lounge areas/waiting areas – will be equivalent to Dwellings – Living room
Arrival lobby – will be equivalent to Offices - Enquiry
Boarding/ check in counters – will be equivalent to Libraries - Counter area
