For a new office project, what is the minimum outdoor water reduction from a baseline required if the owner wants to create a landscape with plants that need watering?

The requirement for outdoor water reduction in the context of landscape design is crucial for promoting sustainability and efficient resource use. According to LEED standards, projects aiming for a sustainable landscape must achieve a minimum reduction in outdoor water usage. In this case, a reduction of 30% from a baseline water use—typically based on the historical watering requirements of the plants being used—strikes a balance between practicality and sustainability.

This percentage encourages the use of drought-tolerant plants, improved irrigation techniques, and smart water management practices. By committing to a 30% reduction, the landscape can still be lush and functional while significantly lowering water consumption, which is beneficial for conservation efforts and aligns well with the broader goals of green building practices.

Choosing to aim for a 30% reduction aligns with LEED's objective to foster a more sustainable built environment while considering the maintenance needs of the landscape. Higher percentages, while more ambitious, may not always be practical for all types of projects, especially ones that include specific plants requiring regular watering.
