Sold on Building Science: NAHB Green Certification

Certified Green Homes by Charles Thomas Homes

Certification is important in the process of green homebuilding because it provides proof that what is promised is what will be delivered. There are other green building programs out there, but the NAHB Green certification program is the only national
standard recognized by the American Standards Association.

According to the NAHB Green website, Green building means incorporating
environmental considerations and resource efficiency into every step of the
home building and land development process to minimize environmental impact.
It’s a practical response to a variety of issues that affect all of us – like
increasing energy prices, waning water resources, and changing weather
patterns. It means making intentional decisions about:

  • Energy efficiency improvements such as high levels of
    insulation, efficient HVAC systems, high-performance windows and
    energy-efficient appliances and lighting
  • Water conservation measures such as water-efficient
    appliances and fixtures, filtration systems, and drought resistant or
    low-maintenance landscaping
  • Resource conservation
    using materials and techniques such as engineered wood and wood alternatives,
    recycled building materials, sustainably harvested lumber, and more durable
  • Indoor environmental quality considerations such as effective HVAC equipment,
    formaldehyde-free finishes, low-allergen materials, and products with minimum
    off-gassing or low volatile organic compounds (VOCs)
  • Site design planning such as minimizing disruption and preserving open
  • Homeowner education
    through manuals and operating guides
  • Green business practices
    that adopt ideas from other industries for saving resources and money in the
    home office

To be certified NAHB Green, the home must go through a checklist of 14 pages. One of
the items on the list is ventilation. Ventilation is a key component to a Green
home because it is necessary for comfort and health.
