How are required credits designated in the Pearl Building Rating System?

In the Pearl Building Rating System, required credits are designated by an 'R'. This designation signifies that a specific credit must be achieved in order for a project to meet the necessary standards set by the Estidama framework. The 'R' indicator distinguishes these essential credits from optional ones, ensuring that project teams focus on key aspects that contribute to the overall sustainability and performance of the building. This clarity helps facilitate compliance with the rating system while promoting environmental stewardship and resource efficiency in construction and design practices.
