Michigan Nursing Home Administrator (NHA) Practice Exam

What is the minimum total window glass area required for rooms used for living or sleeping?

1. 5% of the floor area

2. 10% of the floor area

3. 15% of the floor area

4. 20% of the floor area

The correct answer is: 10% of the floor area

The minimum total window glass area required for rooms used for living or sleeping is typically established by building codes and standards that ensure adequate natural light and ventilation for the occupants. A requirement of 10% of the floor area strikes a balance between providing sufficient daylight and maintaining a feasible approach to design and construction. This percentage has been widely accepted and adopted in various regulations aimed at promoting the health and well-being of residents in living spaces. When this threshold is met, it contributes to a more pleasant indoor environment, reducing dependency on artificial lighting during the day and fostering a connection with the outside. This is particularly important in nursing homes where the well-being and quality of life for residents are paramount. While other percentages, such as 5%, 15%, or 20%, may also reflect certain design philosophies or historical practices, the 10% standard is more commonly recognized in contemporary residential building codes suited for spaces specifically used for living or sleeping.
