LEED - Leadership in Energy and Environmental Design

To provide a national standard of what constitutes a "green building," the Leadership in Energy and Environmental Design (LEED) Green Building Rating System was developed by the USGBC. Through its use as a design guideline and third-party certification tool, LEED aims to improve occupant well-being, environmental performance, and economic returns of buildings using established and innovative practices, standards and technologies.

LEED for New Construction serves as a guide for the design of high performance sustainable commercial and institutional buildings. LEED for New Construction guidelines and requirements are divided among five main categories:

  • Sustainable Sites
  • Water Efficiency
  • Energy and Atmosphere
  • Materials and Resources
  • Indoor Environmental Quality

Two additional categories are Innovation in Design and Regional Priority.

The Certification Process

LEED certification distinguishes building projects that have demonstrated a commitment to sustainability by meeting the highest performance standards.

Why Certify?

  • Establish recognized leadership in the green-building sector.
  • Validate achievement through third-party review.
  • Qualify for a growing array of state and local government incentives.
  • Contribute to a growing green-building knowledge base.
  • Earn LEED certification plaque and certificate.

Eligibility

LEED certification is available for all building types including new construction and major renovation; existing buildings; commercial interiors; core and shell; schools and homes, neighborhood development, retail and healthcare. New building types are being considered and added for LEED certification.

Certification Requirements

LEED is a point-based rating system, and the number of points a project earns determines the level of LEED certification a building project receives.

The levels are based on the total number of points available in that rating system, which are awarded for the design, construction, and operation of a building.

In order to become LEED certified, a building project must satisfy all LEED prerequisites and earn a minimum number of points (40 points out of 100 base points and 10 bonus points) to be certified. Projects are classified as certified, silver, gold, or platinum depending on the total points accumulated.

LEED for New Construction
100 base points: 10 additional points available
Certified Level Minimum 40 points
Silver Level 50-59 points
Gold Level 60-79 points
Platinum Level 80 points and above

LEED for New Construction awards 100 base points in the following five major
categories, with an additional 10 points in two other categories, as identified below:

  • Sustainable Sites (SS) – 26 points available
  • Water Efficiency (WE) – 10 points available
  • Energy and Atmosphere (EA) – 35 points available
  • Materials and Resources (MR) – 14 points available
  • Indoor Environmental Quality (IEQ) – 15 points available
  • Innovation in Design (ID) – up to 6 additional points available
  • Regional Priority (RP) – up to 4 additional points available

LEED credit requirements cover the performance of materials in aggregate, not the performance of individual products or brands. Therefore, products that meet the LEED performance criteria can only contribute toward earning points needed for LEED certification; they cannot earn points individually toward LEED certification.

LEED Credit Areas Impacted by the Use of a ButlerŪ Building

These are the areas in which Butler building systems may contribute to LEED credits on a project:

Sustainable Sites - (SS Credit)

Under the sustainable sites section, the use of reflective and emissive cool metal roofing can contribute one point toward LEED certification.

To qualify, projects must use ENERGY STAR® compliant high-reflectivity and high-emissivity (0.9) roofing, with a minimum solar reflectance index (SRI) of 78, over a minimum of 75% of the roof surface. The Solar Reflectance Index (SRI) is a measure of the roof's ability to reflect solar heat.

Butler offers several sustainable 25-year fluoropolymer paint finishes that meet reflectance and emittance standards for “cool roofs” as set by the Cool Roof Rating Council (CRRC). Butler roof systems that feature the ENERGY STAR label keep buildings cooler by increasing reflectivity, thereby reducing energy use, utility costs and air pollution.

Energy & Atmosphere (EA Credit)

This section requires buildings to comply with ANSI/ASHRAE/IESNA Standard 90.1 2007 or the local energy code, whichever is more stringent.

  • Up to 19 additional points may be awarded for achieving energy performance levels above the prerequisite standard.
  • Increased energy performance may be achieved through the use of metal roof and wall systems designed to provide R-values of up to R-40. Butler offers a variety of energy efficient roof and wall systems that can achieve an R-40 or better.

Materials & Resources---- Recycled Content (MR Credit)

Under this section, the use of steel building systems qualifies projects for one point for the use of material that contains at least 5% recycled content.

Steel is the primary material used to manufacture Butler building systems. In fact, all Butler buildings contain from 20%-70% of recycled steel. In addition to being 100% recyclable and reusable, steel can reduce utility costs, lifetime maintenance and the amount of waste material created.

Regional Manufacturing

Up to two additional points may be awarded for the use of regionally- or locally-available building materials. The intent is to encourage projects to support the regional economy as well as reduce the environmental impacts resulting from transportation.

Butler has 10 regional manufacturing facilities throughout North America (shown in the map below) to help contribute to this credit:
