Green Building Considerations

In the construction of the Walnut Hill Townhomes, considerable attention has been given to Green Building methods and materials. These steps are not only environmentally responsible, but increase the efficiencies of utilities which results in lower utility costs for the owners. Listed below are some of the building considerations that were incorporated.


  • Ultra Therm air infiltration package seals all plumbing, electrical, windows, doors, and other penetrations for convective (air) protection.
  • Premium fiberglass insulation used for conductive (heat loss) protection. Exterior walls, party walls, and floors are R-19 fiberglass batts while ceilings with unconditioned spaces above are R-30 fiberglass batts. Insulation installation meets “grade 1” standards of the Energy Star guidelines.
  • All insulation installed with the Ultra Therm air infiltration package exceeds the Energy Star and EARTHCRAFT standards. For more information go to energystar.org
  • TechShield Radiant Barrier Roof Sheathing (used where applicable) prevents up to 97% of the radiant heat in the panel from radiating in the attic reducing attic temperatures as much as 30 degrees. The result is less heat transfer to living space which means less energy use. For more information go to lpcorp.com
  • Exterior of building envelope with house wrap to reduce air infiltration.


  • Kohler Class Five Cimarron Toilets have eco-friendly setting options-1.4 gpf or 1.28 gpf which can reduce water consumption by 2,000 to 3,200 gallons of water per fixture per year. For more information go to kohler.com/conservation
  • Rennia natural gas tankless instant hot water heaters save energy by heating water on demand rather than constantly heating water in a tank like traditional water heaters.


  • KitchenAid Energy Star rated refrigerators and dishwashers.


  • Andersen 200 Series windows with Low-E Glazing are Energy-Star compliant.
  • Andersen 400 Series patio doors are Energy-Star compliant.
  • Andersen is the first window and patio door manufacturer to be certified by Green Seal, the independent, nonprofit organization dedicated to protecting the environment by promoting the manufacture and sale of environmentally preferable consumer products.

  • Energy Star rated front entry doors by Therma-Tru. For more information see thermatru.com


  • Compact florescent light bulbs standard for recess light fixtures.


  • Wood flooring options such as Bamboo floors.
  • Carpeting made from recycled plastic bottles.


  • Save existing streetscape trees for shade to lower temperature and aid in air quality
  • Use of bio retention for storm water management
  • Recycle existing asphalt parking lot
  • Located near public transportation lines


  • Building design with Low E windows placed for maximum lighting andersenwindows.com
  • Operable windows for ventilation and indoor air quality
  • Detached carriage house parking to keep combustibles and fumes isolated from Main house for indoor air quality
  • Use of pre-engineered wood products and trusses to reduce waste
