Our LEED Platinum Rating

The Duke Smart Home has earned a platinum rating in LEED (Leadership in Energy and Environmental Design) from the United States Green Building Council—the highest possible achievement in green building.

LEED provides an opportunity for all team members to unite around a common goal of sustainablility.

Green Roof

At the Duke Smart Home, our green roof is populated with plants known as sedum—both low-maintenance and drought-resistant. The green roof was donated by American Hydrotech.

Benefits of green roofs include:

  • Preventing heat gain
  • Cooling effect
  • Pre-filtration and buffer of rainwater
  • Aesthetics

Rainwater for Irrigation

Our irrigation system uses 100 percent captured rainwater.

Tap water is never used to water landscaping at the Smart Home. Roof run-off is collected and stored in two 1,000-gallon storage tanks. The collection system was donated by BRAE.
