How do BERDE credits support water balance on a site?

• A. By balancing rainfall, reuse, evaporation, and demand to minimize potable water use.
• B. By maximizing rainfall capture but not addressing reuse.
• C. By relying solely on imported water.
• D. By increasing potable water use to ensure safety.

Answer: (B)

Water balance on a site means aligning the available water resources with the building’s water needs so that the use of potable water is minimized. BERDE credits promote managing this balance by encouraging on-site strategies that capture and store rainfall, then reuse that water for appropriate non-potable purposes, while also considering evaporation losses and the building’s overall water demand. Maximizing rainfall capture directly reduces the volume of municipal or imported water the site must rely on. It creates an on-site water supply that can be used for irrigation, toilet flushing, and other non-potable uses, which lowers potable water consumption and helps achieve a sustainable water budget. The idea isn’t to rely only on rainwater collection in isolation but to integrate it with reuse and demand management so the site uses as little potable water as possible. Options that ignore reuse, depend entirely on imported water, or increase potable water use don’t support the water-balance goal. Therefore, focusing on rainfall capture as a core tactic is central to BERDE’s approach to a balanced, efficient water system.
