Question

All habitable rooms shall be provided with aggregate glazing area of not less than ___ percent of the floor area of such rooms.

1) 10%
2) 20%
3) 30%
4) 40%

Answer 1

The common building code requirement is for the aggregate glazing area to be not less than 8% of the floor area for natural light, but given the options, the closest standard requirement is 10% of the floor area.

Step-by-step explanation:

The question you've asked pertains to building codes and requirements for the amount of glazing (windows) in habitable rooms. In many building codes, there is a requirement that each habitable room must have a certain percentage of its floor area made up of glazing to allow for natural light and ensure the health and comfort of the occupants. While the exact percentage can vary by location and specific code, a common requirement is that the aggregate glazing area must be not less than 8% of the floor area for natural light, and sometimes an additional 4% for ventilation if not provided by mechanical means, totaling 12%. However, in the absence of a specified figure in your question, the general answer among the options provided would be 10%, which is closest to the common standard for natural light alone. Remember, always refer to your local building codes for the most accurate and legally binding requirements.
