GREEN GLOBES #4.8.1.1.1 - ANSI #9.8.1.1 Is there a 30% reduction in water demand compared to the baseline as determined by the EPA WaterSense Water Budget Tool?

• Yes (6 points)
• No (0 points)

Note: Criterion only visible if 4.8.1.1 is answered with "No"

Assessment Guidance

Use the EPA WaterSense Water Budget Tool to determine landscape water allowance (LWA) and the landscape irrigation design and installation aligns with the allowance.

Exclusion: The area of the landscape used to grow food for human consumption is not included in the calculations.
