The National Green Building Standardâ„¢ (NGBS) is the preeminent residential green building rating system. It sets green baselines for all new residential construction, development, and remodeling projects. ANSI-approved and consensus-based, the NGBS provides a menu of green building practices for builders, remodelers, and developers to plan their green projects. Home Innovation Research Labs, an independent, third-party research and testing organization, certifies homes, buildings, subdivisions, and remodel projects as in compliance with the NGBS.


For builders and remodelers, green building means making intentional decisions about:


Energy Efficiency

Improvements such as high levels of insulation, efficient HVAC systems, high-performance windows and energy-efficient appliances or lighting.

Water Conservation
Measures such as water-efficient appliances, water-conserving fixtures, water filtration systems, and water-efficient or low-maintenance landscaping.

Resource Conservation
Using materialsand techniques such as high-performance engineered wood, wood alternatives, allergen-free materials, recycled building materials, sustainably harvested lumber and more durable products.

Indoor Environmental Quality
Considerations such as effective HVAC equipment, use of formaldehyde-free finishes, and use of products with minimum off-gassing or low volatile organic compounds (VOCs).

Site Design
Planning such as minimizing disruption and preserving open space.

Home Owner
Education through manuals and operating guides.

As well as,
Green Business Practices that adopt ideas from other industries for saving resources and money in the home office.

Market research indicates that home buyers are looking for the efficiency, durability, and low-maintenance features of green homes. Third-party certification, like NGBS Green certification through Home Innovation Research Labs, provides a consistent standard in the marketplace and offers a way for builders to differentiate themselves from their competition.

HBA of Delaware encourages this growth to continue and assure that green practices remain flexible, voluntary and cost-effective.
