means where permitted by the Uniform Building Code. When the system provides ventilation
through a dedicated opening, such as a window or through -wall vent, these openings must:
• Have controlled and secure openings
• Be sleeved or otherwise designed so as not to compromise the thermal properties of the wall or
window in which they are placed.
• Provide not less than 4 square inches of net free area of opening for each habitable space.
