LEED Certification: Building for the Future

Energy & Atmosphere

EA Prerequisite 2 – Minimum Energy Performance

Intent
Establish the minimum level of energy efficiency for the proposed building and systems.

Marvin products meet or exceed current ASHRAE 90.1 provisions which assists projects in achieving this Energy Performance criteria.

EA Credit 1 – Optimize Energy Performance – 1 to 19 Points
Note: 2 Points are mandatory

Intent
Achieve increasing levels of energy performance above the baseline in the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use.

Marvin can help achieve increased levels of energy performance in the following ways:

• High performance glazing: Marvin offers a High-R glazing option in some product types with wood windows that includes triple glazing with two low-e coatings and argon gas-fill. U-factors as low as 0.18 for Marvin wood windows are found in the NFRC Certified Products Directory, with many products having U-factors below 0.25. See NFRC values for specific products.
• Low infiltration rates: High levels of performance (DP ratings) on all Marvin products translate into low air infiltration rates.
• Solar heat gain: Marvin offers options that can maximize or reduce solar heat gain, especially when used in conjunction with overhangs and other  design strategies.
• Electric operators: Remote electric operation of casement and awning windows can be triggered by sensor inputs from the facility's Building Autmation System and/or the HVAC system.

Materials & Resources

MR Credit 2:  Construction Waste Management 1 to 2 Points

Intent
Divert construction, demolition and land-clearing debris from disposal in landfills and incinerators. Redirect recyclable recovered resources back to the manufacturing process. Redirect reusable materials to appropriate sites.

Marvin ships all products wrapped and cornered, rather than fully cartoned, to reduce packaging waste, most of which, including cardboard and plastic wrap, is fully recyclable. Marvin products are also available with a factory-applied prime coat to minimize on-site painting waste.

MR Credit 4:  Recycled Content 1 to 2 Points

Intent
Increase demand for building products that incorporate recycled content materials, thereby reducing impacts resulting from extraction and processing of virgin materials.

Marvin products incorporate recycled materials extensively. Our glass contains 20% pre-consumer recycled content. Our major aluminum supplier currently uses 30-35% purchased  (post-consumer) scrap/recycled aluminum and 40% in-house (pre-consumer) scrap. Our fiberglass contains 10% recycled content. Average window composition is 30-60% glass, 30-60% wood and 0-15% aluminum.

To obtain calculations for recycled content of Marvin products used in your project, contact your Marvin representative.

MR Credit 5:  Regional Materials 1 to 2 Points

Intent
Increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation.

Projects within 500 miles of Warroad, Minnesota (windows) or Ripley, Tennessee (doors) may be able to claim glass and Ultrex values under the Regional Materials credit.

If your project meets these geographic requirements, please contact your Marvin representative for further information.

IEQ Credit 6.2:  Controllability of Systems -- Thermal Comfort 1 Point

Intent
To provide a high level of thermal comfort system control by individual occupants or groups in multi-occupant spaces (e.g., classrooms or conference areas) and promote their productivity, comfort and well-being.

Natural ventilation, using operable Marvin windows and mechanical window systems that meet or exceed requirements of ASHRAE Standard 62.1-2007 paragraph 5.1, Natural Ventilation, can be integrated into HVAC system planning.

Indoor Environmental Quality

EQ Credit 8.1 – Daylight and Views - Daylight 1 Point 

EQ Credit 8.2 – Daylight and Views - Views 1 Point

Intent
To provide for the building occupants a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.

Marvin windows and doors offer countless options for enhancing daylight and views throughout a structure. Our products’ high thermal efficiency provides added value when designing openings to meet 75% daylight and 90% view requirements for all regularly occupied spaces. See Daylight Opening Conversions for specific products.

Regional Priority 

RP Credit 1 – Regional Priorities – 1 to 4 Points

If you can claim credit for any of the Marvin-applicable  LEED categories listed above, they may be eligible for Regional Priorities bonus points. See the LEED list of state regions for Regional Priorities requirements in your area.
