LEED® (Leadership in Energy and Environmental Design) Green Building Rating System™

Following the formation of the U.S. Green Building Council (USGBC) in 1993, the organization’s members quickly realized that the sustainable building industry needed a system to define and measure ‘green buildings’. Since the first pilot program was introduced in 1998, the LEED® (Leadership in Energy and Environmental Design) Green Building Rating System™ has evolved and reacted to the changing green building landscape around it.

The LEED® Green Building Rating System is a set of performance standards based on existing and proven technology, to evaluate environmental performance from a whole building perspective over a building’s lifecycle. They provide a definitive standard for what constitutes a green building in design, construction and operation.

LEED® version 3 prerequisites and credits address seven topics; sustainable site development, water efficiency, energy and atmosphere, material and resources, indoor environmental quality, innovation in design, and regional priority. Armourcoat products qualify for LEED® points in two key areas; materials and resources and indoor environmental quality. However, it is worth noting that LEED® guidelines vary from one LEED® program to another. Not all LEED® programs are the same. Categories may change; therefore it is always recommended that you consult with the GBCI (Green Building Certification Institute) prior to making final selections.

Materials & Resources – credit 4: ‘recycled content’

1 to 2 points

During both the construction and operations phases, buildings generate a lot of waste and use a lot of materials and resources. This credit category encourages the selection of sustainably produced products and materials. Requirement is to use materials with recycled content such that the sum of post-consumer recycled content plus ½ of the pre-consumer content constitutes at least 10% (1 point) or 20% (2 points) based on cost, of the total value of materials in the project.

Indoor Environmental Quality – credit 4.2: ‘low-emitting materials – paints and coatings’

1 point

The U.S. Environmental Protection Agency estimates that Americans spend about 90% of their day indoors, where the air quality can be significantly worse than outside. The Indoor Environmental Quality credit category promotes strategies that can improve indoor air as well as providing access to natural daylight and views and improving acoustics.

Requirement is to use architectural paints and coatings applied to interior walls and ceilings which do not exceed the VOC (Volatile Organic Compound) content limits established in Green Seal Standard GS-11 (<50g/l).
