For maximum points under WE 1.1 Rainwater harvesting, what applications should the storage system primarily serve?

For maximum points under WE 1.1, the storage system for rainwater harvesting should primarily serve applications related to irrigation and toilets. This is because these uses are typically the most sustainable and resource-efficient applications of harvested rainwater.

Using harvested rainwater for irrigation helps conserve potable water resources and reduces the demand on municipal water supplies, especially in regions susceptible to drought. Additionally, using rainwater in toilets significantly reduces the use of drinking water for sanitary purposes, which is a substantial water-saving strategy in buildings.

While other applications like building cooling systems or swimming pools can utilize harvested rainwater, they may not contribute as directly to water conservation goals associated with LEED. Swimming pools often require extensive treatment and maintenance, which can offset some of the benefits of using harvested water. Therefore, the emphasis on irrigation and toilets aligns with the LEED objectives of enhancing water efficiency and sustainability practices.
