I am working on a basement plan, and my village stated I will need to provide a light vent schedule. As this is a basement there are limited windows.
We will have a 600 sq ft open space (play area and game room) and then a 45 sq ft bathroom, and a 157 sq ft bedroom.
Bedroom will have a 48"x48" egress window.
Bathroom no window but we will be installing an exhaust fan with a light.
Play room has 2 existing egress windows sized at 38.5" x 44"
I saw the code we need to meet 8% ratio of sq ft for natural light, and 4% for ventilation. Bathroom and play area do not meet the requirements for natural ventilation/light.
The sample schedules I found online (tables with Room, sq ft, light required, light provided, etc.) show some rooms not meeting the requirements like mine. However they do not show what I need to do to show artificial light supplements this and meets the requirements? Is there something I need to provide for that, or I just need to provide a light vent schedule table showing the rooms failing and with my electrical plans they will see all the recessed cans and exhaust fan for my bathroom?
I could not find the artificial light requirements for a room in the IRC (Just this part:401.3).
Additionally this area will not meet the natural ventilation requirements so if I fill out one of the sample tables I saw, what do I need to meet the mechanical ventilation requirements of this? We have a forced air system with Trane furnace and A/C that has a fresh air duct tied to it with a damper that opens for X minutes per hour.
Appreciate any guidance you can provide
