LEED AP Building Design and Construction (BD+C) Practice Exam

What percentage of building occupants must have individual comfort controls for thermal comfort?

1. 25%

2. 50%

3. 75%

4. 100%

The correct answer is: 50%

The requirement for thermal comfort in buildings, as outlined in the LEED BD+C Rating System, emphasizes the importance of providing building occupants with individual comfort controls. To achieve the credit related to thermal comfort, the standard stipulates that at least 50% of the occupants must be able to control their own thermal environment. Individual comfort controls can include options such as operable windows, adjustable thermostats, and other means that allow occupants to personalize their thermal comfort. This approach recognizes the diversity in preferences among individuals, as factors such as clothing, activity levels, and personal comfort preferences can vary significantly. By allowing half of the occupants to have this level of control, the building can better meet the needs of its users and enhance their overall comfort. While achieving 100% would provide complete control for every individual, the standard acknowledges that this may not be feasible in all building types or scenarios. Thus, a requirement of 50% strikes a balance between occupant comfort and practical implementation within various building designs and functions.
