What should the minimum net glazed area not be less than as a percentage of the floor area of the room served?

8 percent
10 percent
15 percent
25 percent

The correct answer is: 10 percent

The correct percentage for the minimum net glazed area in relation to the floor area of the room served is 10 percent. This standard is established to ensure adequate natural light and ventilation within a space. Proper daylighting can enhance the comfort and well-being of occupants, thereby improving productivity and mood. The minimum requirement of 10 percent allows for enough natural light to enter the room, which is particularly essential in living and working spaces. Without sufficient daylight, rooms can feel cramped and uninviting, potentially leading to higher energy consumption as artificial lighting is used more frequently. Additionally, adequate ventilation that can be aided by glazed areas contributes to a healthier indoor air quality, which is vital for overall health. Other percentage options, while they may reflect different building codes or preferences, do not adhere to the balanced approach of promoting both light and ventilation within standard building practices. These percentages would either provide insufficient light, thereby affecting usability and livability, or create unnecessary glare or heat gain, leading to discomfort and potential energy inefficiencies.
