Is There An Official Definition Of Green?

No. Many different measures or standards can be applied to designate a practice or a product as “green”. For construction, remodeling, or DIY projects, “Green” currently references the incorporation of practices that decrease impact on the environment. This can include, but is not limited to, the use of low VOC content paint products that have reduced VOC emissions.

What Are The Standards Used To Determine "Green"?

While there is no single authority on what makes a product green, three different types of standards are often used. They include governmental regulations, the widely accepted United States Green Building Councils’ Leadership in Energy and Environmental Design (LEED®) Green Building Rating System™ and independent certifying bodies, such as the Collaborative for High Performance Schools (CHPS).

What Is A VOC?

Volatile Organic Compounds (VOCs) are carbon-containing chemicals which are released into the atmosphere from both man-made and naturally occurring materials. Because of their impact on air quality, they are subject to a variety of regulatory definitions depending on jurisdiction and product type. For architectural coatings, VOCs result from the use of solvents and thinners which evaporate into the air as the paint dries. Outdoors, they can contribute to ground-level ozone, forming smog. Indoors, they can affect air quality both in the short term during the painting process and in the long term through continued off-gassing.

What Is LEED?

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. The LEED rating systems are developed by the US Breen Building Council (USGBC) committees, in adherence with USGBC policies and procedures guiding the development and maintenance of rating systems. The LEED Rating System was created to transform the built environment to sustainability by providing the building industry with consistent, credible standards for what constitutes a green building.

What Are The Benefits Of LEED Certification?

LEED certification is third-party validation of a building’s performance. LEED-certified projects blend environmental, economic, and occupant-oriented performance. They cost less to operate and maintain, are energy- and water-efficient, have higher lease-up rates than conventional buildings in their markets, and are a physical demonstration of the values of the organizations that own and occupy them.

Can Products Be Certified Under LEED?

No. LEED applies to green building projects. Individual products can contribute to points under the rating system; LEED criteria are performance-based. In attempting to meet these requirements, LEED practitioners identify products that have desired attributes. However, some LEED criteria do require specific product data as a part of a successful submittal.
