Harvesting Rainwater

Living Buildings must minimize stormwater runoff. The Kendeda Building’s landscape mimics the Piedmont Forest’s hydrology through seepage areas, rain gardens, and permeable pavers, allowing most rainwater to absorb into the ground.

Rainwater is also collected from the solar panels, roof deck, and green roof, then filtered into a 50,000-gallon basement cistern. This system captures about 40% of annual rooftop runoff. When the cistern is full, excess water is directed to on-site stormwater systems.

The solar canopy is also a key design feature that gets The Kendeda Building to net positive energy.

Portions of the solar canopy that overhang the roof have gutters that channel rainwater to the roof, where the water is drained into the cistern.
