Which of the following is not included in the landscape program for exterior water use reduction?

The rationale for this answer lies in the framework of the Estidama Pearl Building Rating System (PBRS) and its approach to landscape water use reduction strategies. The landscape program focuses on practices that directly influence the efficiency and sustainability of exterior water usage.

Plant Selection Guidelines emphasize choosing native or drought-tolerant species that require less water, thereby naturally reducing water demand. A Landscape Irrigation Schedule establishes when and how much water to apply in order to optimize irrigation without wastage, while Soil Moisture Management practices monitor and adapt irrigation based on the actual soil moisture content, ensuring that plants receive only as much water as needed.

Although Annual Water Demand is a crucial aspect of understanding water usage over the year, it does not encompass the proactive measures and design strategies that the program promotes for immediate landscape management. The emphasis is on optimizing the practices surrounding irrigation and plant selection to minimize water usage, rather than simply measuring the demand over time, which is more of a retrospective evaluation rather than a direct landscape management strategy. Therefore, it is not included as a component of the landscape program focused on exterior water use reduction.
