Which feature is linked to water efficiency in the material?

• A. Use of local vegetation that may require minimal maintenance and water usage
• B. Use of high energy-consuming equipment
• C. Flat roof without insulation
• D. Overuse of non-renewable materials

Answer: (A)

Water efficiency in building with landscape practices is most directly improved when the plan uses local vegetation that naturally requires little irrigation. Native or drought-tolerant plants are adapted to the local climate and soils, so they need less supplemental water, fewer frequent watering events, and generally lower maintenance. This reduces outdoor water demand and the overall freshwater impact of the project, which is exactly what water efficiency aims to achieve. The other choices don’t target water use: high-energy-consuming equipment relates to energy efficiency, not water; a flat roof without insulation worsens thermal performance and increases cooling needs (which can indirectly affect overall resource use, but not specifically water efficiency); and overusing non-renewable materials concerns material sustainability rather than water use.
