Green Building

Neighborhood Builders is a NHAB Certified GREEN Professional and all of our Homes are 5-Star Energy Certified and Built to NHAB Green standards.

Here is a few of the steps taken to ensure efficiency in all of our homes:
  • Interior and Exterior Drain Tile – To prevent moisture build up
  • Low E Windows – Glass coatings are transparent that reflect up to 90% of long wave heat energy
  • Low U Window factors – The U factor refers to the rate of heat loss through the window. Using a lower factor indicates a higher insulating value
  • Roof Overhangs & Covered Entry – Roof overhangs and covered entries are used to help reflect heat from the sun and shed water
  • Engineered Wood Products (EWP) – such as roof trusses, i-joists laminated and glue lam material
  • OSB – Oriented Strand Board plywood is used in place of plywood
  • Alternative Siding Products – Fiber cement siding and masonry products are more sustainable in our geographic area and more energy efficient
  • Composite Materials: Various parts of the home are replaced with composite materials such as decking or Fypon products in replace of wood.
  • Blown Cellulose Insulation – Consisting of recycled news paper; an adhesive agent is added and sprayed in all walls providing an air tight home with a high R value
  • Recycled Gypsum – 15% of construction waste is dry wall and is recycled into new gypsum board
  • RUUD 96% Gas Furnaces – Careful selection and sizing is used on all heating and cooling equipment to increase efficiency and lengthen equipment life. All gas furnaces are 2 stage veritable speed and include a 10 Year Warranty
  • RUUD Thermostats - our WiFi ready touch screen thermostats provide high tech efficiency with convenance such as built-in humidity controls
  • Honeywell Fresh Air Ventilation Systems – This system allows fresh air to be introduced into the home and increase your systems efficiency.
  • LifeBreath - Heat recovery ventilators provided maximum home ventilation
  • AprilAir 500 Humidifiers - optional powered units provided maximum humidity control
  • Sealed Duct work – All aluminum ducts are caulked and sealed from leaking
  • HYDRON MODULE Geo Thermal Systems – Using the earth to transfer heat to and from the soil is a very energy efficient and comfortable way of living. Learn more at
  • Radiant Floor heating - Geo thermal or stand alone power offers comfort and efficiency
  • Tankless Hot Water Heaters – This option allows water to only be heated when needed to save energy and provide comfort
  • Lighting & Lighting Controls – High efficiency florescent bulbs and dimmers are used to increase energy efficiency
  • Appliances – High efficient Energy Star appliances are used to save up to 30% of typical energy costs
  • Shaw Flooring Products – Shaw flooring products including carpeting, carpet pad, wood laminate, cork flooring and ceramic tile are made of recycled materials
  • Recycling Construction and Demolition Waste – All construction waste is shipped directly to Des Moines local recycling plant.
Verifying energy performance of our homes:

To insure that all features and systems of our homes are built and function as intended Heartland Energy Solutions is used as a third party inspector to inspect insulation, duct work, heating and cooling systems and perform a blower door test to meet all 5Star Energy requirements and meet NHAB Green building standards. In addition the following steps are taken to verify the energy performance of our homes:
  • Testing & commissioning of HVAC systems
  • Insulation inspection
  • Blower door testing for house tightness (building envelop and leakage)
  • Home energy ratings
  • Test all components of the home
  • Adjust all systems to maximize efficiency
  • Provide maintenance training and manuals for our homeowners
