Final answer:
The percent of applicable exterior luminaires that must meet uplight and light trespass requirements depends on the specific requirements set for the project, such as 90%.
Step-by-step explanation:
In order to determine the percent of applicable exterior luminaires that must meet uplight and light trespass requirements for SSc Light Pollution Reduction, we need more information. The percentage would depend on the specific requirements set for the project. However, let's say that the requirement is that at least 90% of applicable exterior luminaires must meet uplight and light trespass requirements.
For example, if there are 100 applicable exterior luminaires, then 90 of them must meet the requirements. This would be equivalent to 90%.
It is important to note that the specific requirements can vary depending on the specific project or guidelines being followed.
