Open-grid paving can be just as durable as other types of paving, but it may require additional maintenance to ensure that open cells do not become clogged.
Open-grid paving is different from porous paving—Open grid paving is laid out in a pattern that exposes areas of the ground allowing vegetation to grow in the open cells. Porous paving is continuous paving that allows water to penetrate it minimizing runoff.
Using open-grid paving allows water to infiltrate the ground, which could also help your project team achieve the stormwater management credits SSc6.1 and SSc6.2.
Canopies, terraces, balconies, and other architectural devices are covered by the calculations for this credit if they do not have conditioned space below them. Coverings that have conditioned space below are considered roofs and are covered under SSc7.2: Heat Island Effect—Roof.
