LEED Rating

The Home Depot Smart Home at Duke University has earned a Platinum rating in LEED (Leadership in Energy and Environmental Design) from the United States Green Building Council USGBC. LEED Platinum is widely considered to be the highest possible acheivement in green building. LEED is an opportunity for all team members on a building project to unite around the common goal of building in a more sustainable way. The Home Depot Smart Home at Duke is a premier example of focusing team effort on sustainable building techniques.

Sustainable Sites

Green Roof - A green roof (also knows as a vegetated roof) is an area of roof surface that is covered with living plant matter. In the case of the Smart Home, the green roof is populated with sedums that are low maintenance and drought resistant. The Green Roof on The Home Depot Smart Home was donated by American Hydrotech. Benefits of Green Roofs include:

  • Preventing Heat Gain (Urban Heat Island Effect)
  • Evaporation creates a cooling effect on building
  • Pre-filters rain water (For re-use later)
  • Buffers rain water so that it doesn't run off-site rapidly carrying pollutants
  • Aesthetically pleasing

Water Efficiency

Rain Water for Irrigation - The irrigation system for The Home Depot Smart Home uses 100% captured rainwater. This guarantees that no public water will ever be used to water vegetation on the Smart Home site. The rainwater is collected from roof run-off and stored in two 1000-gallon storage tanks for later use. The Rainwater collection system was donated by BRAE.

LEED Credits Targeted:

      WEc1.1 - Water Efficient Landscaping, Reduce by 50%


      WEc1.2 - Water Efficient Landscaping, No Potable Use or No Irrigation


      WEc2 - Innovative Wastewater Technologies


      WEc3.1 - Water Use Reduction, 20% Reduction


    WEc3.2 - Water Use Reduction, 30% Reduction

Energy & Atmosphere

Photovoltaic Panels - At the Smart Home, there is an array of 18, 160 watt photovoltaic panels which creates a ~3kW solar power station. The energy generated by the panels is connected to the public power grid and puts energy back onto the grid for use by the neighbors. It also reduces the total energy consumed by the Smart Home by about 30%.

LEED Credits Targeted:

      EAp1 - Fundamental Building System Commissioning


      EAp1 - Minimum Energy Performance


      EAp1 - CFC Reduction in HVAC&R Equipment


      EAc1 - Optimize Energy Performance


      EAc2 - Renewable Energy


      EAc3 - Additional Commissioning


      EAc4 - Ozone Depletion


      EAc5 - Measurement and Verification


    EAc6 - Green Power

Materials & Resources

Construction Waste Management - All waste generated at The Home Depot Smart Home site during construction is placed in a single bin for convenience. When the bin is collected, it is taken to a sorting facility where the waste is separated into disposables and recyclables. Using this process more than half of the total waste is being diverted from landfills.

LEED Credits Targeted:

      MRp1 - Storage and Collection of Recyclables


      MRc2.2 - Construction Waste Management, Divert 50%


      MRc4.1 - Recycled Content - Specify 5%


    MRc5.1 - Local/Regional Materials, 20% Manufactured Locally

Indoor Environmental Quality

Daylight and Views - Research has shown that providing daylight views to building occupants increases productivity. Anecdotal evidence suggests that having access to daylight views creates happier residents. In the Smart Home greater than 90% of locations inside the building have direct daylight views.
