LEED Green Building Program

LEED = The Leadership in Energy and Environmental Design “Aims to improve occupant well-being, environmental

performance and economic returns of buildings” A rating system Projects earn one or more points toward

certification by meeting or exceeding each credit’s technical requirements.

Points add up to a final score Score relates to one of four

possible levels of certification

Sustainable Sites – 14 pts.– Heat Island Effect

Water Efficiency – 5 pts.

Energy & Atmosphere – 17 pts.– Optimize Energy Performance

• Up to 10 points

Materials & Resources – 13 pts.

- Points from Metal Buildings

Indoor Environmental Quality – 15 pts.

Innovation & Design Process – 5 pts.– LEED Accredited Professional

LEED Rating System – ABC BuildingsThe LEED Rating System rates the aggregate system of a building. The individual components of a building do not, by themselves earn points. However, this chartshows how products provided by American Building Company can contribute toearning LEED points.

PotentialLEED Section * Subject Points ABC Contribution

SS Credit 7.2 Heat Island Effect 1 ABC's Regal White has a Solar - Roof Reflectance Index (SRI) over 78

MR Credit 3.1 & 3.2 Materials Reuse 2 All ABC steel materials are 100%recyclable in the future.

MR Credit 4.1 & 4.2 Recycled Content 2 ABC recycled steel content over 70%

MR Credit 5.1 & 5.2 Use of Regional 2 ABC multiple plant locations and Materials Nucor domestic steel mills can often

contribute to the use of regional materials. This varies with the job sitelocation.
