An elementary school requires a renovation, selective demolition, and a major addition in order to accommodate a growing student population. An architectural firm has prepared schematic design plans incorporating the school's increased programmatic needs, including an enlarged library, cafeteria, and gymnasium; a secure courtyard; and additional space for administrative offices and classrooms. The main entrance was relocated in order to improve the traffic and pedestrian flow at the beginning and end of the school day, and additional parking was provided to comply with current zoning requirements.
The existing single-story masonry building was built in 1950. Two small additions were built later: the north addition will be kept and repurposed, but the south addition will be demolished. The building contains asbestos and lead in roof soffits, floor tiles, pipe insulation, and window paint. All existing mechanical systems need to be replaced; new systems have not been selected.
Considerations for the renovation include:
* The relocated front entrance must be easily recognizable, highly visible, and secure.
* Interior and exterior materials need to be durable and maintainable in order to withstand frequent student abuse, but also economical due to strict budget limitations.
* Good indoor air quality and increased energy efficiency are priorities for the selection of mechanical equipment.
After completion, the entire school should look uniform, without a distinctive difference between the existing building and new addition.
Building information:
* Construction Type is II-B.

An elementary school library has an occupancy load of 150.
What is the minimum clear opening width required?
Comprehensive and Detailed Explanation From Exact Extract:
According to ADA Standards and IBC egress requirements for an occupancy load of 150, the minimum clear opening width for doors must be at least 36 inches to accommodate the expected occupant flow and provide accessible egress.
30' or 32' openings are too narrow for this occupancy load.
Ensuring the minimum door width meets code is essential for safe and accessible design.
