Today, we will discuss another Credit Category of the LEED v4 Certification Program, Water Efficiency. Earning points in this credit category will go toward rating your site with one of the US Green Building Councils’ coveted LEED Certification, ranging from the base level to Platinum.

Below, let’s discuss some of the point categories that fall within the Water Reduction Credit Category:

The goal is to reduce outdoor water demand, which is done through high efficiency fixtures and fittings.

There are two routes that you can take to achieve points in this aspect: 1. You can reduce the percentage of turf grass and increase the native plants in percentage of the total landscape area.

The second route is to have installed a highly efficient irrigation system. Various points are awarded for having proper pressure regulation, smart irrigation control and flow sensing with a master valve.
