A Product Solution for Green Architecture and Sustainable Building Design

In today’s world, an awareness and demand for energy efficient, environmentally friendly products is rapidly growing. Manufacturers have been challenged to meet the demand for products that are “greener” and longer lasting, particularly in products such as insulation and roofing materials.

MCA clay tiles meet many standards defined by the U.S. Green Building Counsel’s Leadership in Energy and Environmental Design (LEED) program, which, among other things, promotes integrated, whole-building design practices, and recognizes environmental leadership in the building industry. Creating a “green” building, in effect, means matching the products and materials to the specific project design and site in order to minimize the overall environmental impact. In the past, building green was often associated with higher “first costs” versus savings on the “life cycle” maintenance costs. But, today, building green is a good long-term investment that doesn’t have to cost more than a building with traditional materials. Saving energy not only benefits the environment and saves money by lowering energy costs, but also, MCA’s “Cool Roof” tile comes at no additional cost.

 MCA Clay Roof Tile can also contribute to earning LEED v4 rating points. Below is a list of LEED v4 Credits that can be earned by using MCA Clay Roof Tile.

Sustainable Sites

  • Heat Island Effect Reduction (1 possible point)
    • To minimize effects on microclimates and human and wildlife habitats by reducing heat islands.
    • Option 1. Nonroof and Roof (2 points except healthcare, 1 point healthcare)
  • Rainwater Management(Homes category only, 1-3 possible points)
    • To reduce rainwater runoff volume from site.
      • Ensure that at least 50% of total lot area is permeable or can direct water to an onsite catchment or infiltration feature.
      • 50-64% =1 point, 65-79% =2 points, 80% and above =3 points
  • Case 1. Low Impact Development
    • Clay roof tiles can assist with a rainwater management system and earn points when combined with other techniques. Clay Roof Tiles are smooth, hard, and do not shed contaminants.

Energy & Atmosphere

  • Optimize Energy Performance
    • Achieve increasing levels of energy performance beyond prerequisite standard to reduce environmental and economic harms associated with excessive energy use.
    • Option 1. Whole-building Energy Simulation
      • Analyze efficiency measures
      • Use energy simulation of efficiency opportunities
      • Many of MCA’s colors would assist in reaching the specified reduction of design energy cost. This credit recognizes the environmental benefits of reduced power consumption.

Materials & Resources

  • Sourcing Raw Materials
    • To reward project teams for selecting products verified to have been extracted or sourced in a responsible manner.
    • Option 2.Leadership Extraction Practices (1 point)
      • Use products that meet responsible extraction criteria such as Recycled Content for at least 25%, by cost of total value of permanently installed building products in the project.
      • Products sourced (extracted, manufactured, and purchased) within 100 miles of project site are valued at 200% of base contributing cost.
      • 60% of MCA’s clay content is pre-consumer recycled material.
      • MCA plant is located in Corona, California. For projects in Southern California, MCA tile can be valued at 200% of the base cost if project site is within 100 miles of the manufacturing plant.
      • Equation 1 Recycled content Value ($)=(% post-consumer recycled content x material cost) +(0.5 (% pre-consumer recycled content x material cost))

        Equation 2 Recycled Content % for project = Total Recycled content Value ($)/Total Materials Cost ($)

        Environmentally Preferable Products (homes category only) 

        • To increase demand for products that minimize material consumption through recycled and recyclable content, reclamation, or overall reduced life-cycle impacts.
        • Option 2. Environmentally Preferable Products (1 point for roofing)
          • Products sourced (extracted, manufactured, and purchased) within 100 miles of project site are valued at 200% of base contributing cost.
          • At least 90% of building component, by weight or volume, must contain at least 25% postconsumer or 50% pre-consumer content
          • 60% of MCA’s clay content is pre-consumer recycled material.
