Earning LEED Credits with Duo-Gard's Collaboration
The credits below show where Duo-Gard's daylighting systems, photovoltaics and specialty structures can help your project earn LEED points across each category.
Sustainable Sites (SS)
Alternative Transportation
Bicycle Storage and Changing Rooms
Duo-Gard provides secure bicycle storage through custom and standard bike shelters, racks and accessories that integrate solar and LED technologies, along with bus shelters and specialized outdoor structures.
Heat Island Effect, Nonroof
Structures must provide a solar reflective index (SRI) of minimum 29. Duo-Gard's translucent canopies, walkways and special structures can meet this requirement, and photovoltaic canopies provide shading over parking and surfaces to reduce heat absorption.
Heat Island Effect, Roof
Use materials with SRI 29 for steep-sloped or SRI 78 for low-sloped roofs covering a minimum of 75% of surface area. Duo-Gard's translucent roof systems can be engineered for compliance.
Light Pollution Reduction
Minimize trespass of interior lighting to the outside. Duo-Gard's translucent skylights, walls, ceilings and accents are engineered to diffuse direct-beam light without additional shielding.
Energy and Atmosphere (EA)
Minimum Energy Performance
Improve building performance by 10% for new construction or 5% for major renovations using ANSI/ASHRAE/IESNA Standard 90.1-2007. Duo-Gard's high-performance daylighting systems achieve high insulating values with maximum diffused light transmission while reducing solar heat gain and winter heat loss, supported by complimentary daylight modeling services and photovoltaic systems.
Optimize Energy Performance
Improve whole-building energy efficiency by 8%–48% beyond the prerequisite standard, depending on construction type. Duo-Gard offers double-glazing, IR coatings, LED strategies and Lumira® insulating aerogel, with daylight modeling and photovoltaic systems to assure success.
On-Site Renewable Energy
Encourage increasing levels of on-site renewable energy from 1%–13% of annual energy costs. Duo-Gard systems provide building-integrated photovoltaics (BIPV) solutions.
Green Power
Encourage grid-source renewable energy technologies on a net-zero pollution basis, with owners contracting for a minimum of 35% renewable electricity. Duo-Gard's on-site solar photovoltaic systems help achieve this goal economically.
Materials and Resources (MR)
Building Reuse
Maintain Existing Walls, Floors & Roof
Maintain existing building structure and envelope. Duo-Gard's overglazing systems cover existing walls, windows and skylights without demolition while increasing energy efficiency and updating appearances.
Recycled Content
Use materials with 10% or 20% post-consumer plus ½ pre-consumer recycled content. Duo-Gard's multiwall polycarbonates contain 20–40% pre-consumer recycled content upon request. Polycarbonates and aluminum are completely recyclable, as is Lumira® insulating aerogel (C2C Certified).
Regional Materials
Use a minimum of 10%–20% of materials extracted, harvested, recovered or manufactured within 500 miles of the site. All systems are manufactured in Canton, Michigan.
Qualifying states within the required radius:
Indoor Environmental Quality (IEQ)
Environmental Tobacco Smoke (ETS) Control
Prevent or eliminate exposure to environmental tobacco smoke. Duo-Gard pioneered the smoking shelter in 1990, offering standard and custom styles compliant with the “25 feet from entrances” requirement.
Increased Ventilation
Include additional ventilation from outdoor air. Duo-Gard's daylighting systems can integrate operable sections providing ventilation.
Controllability of Systems, Thermal Comfort
Provide individual temperature control or operable windows for 50% of occupants. Duo-Gard's translucent daylighting systems can be engineered with operable sections for individual comfort.
Thermal Comfort, Design
Create a comfortable thermal environment for occupants. Duo-Gard's high-performance daylighting integrates polycarbonates for high diffused light transmission without glare or solar heat gain, coupled with proprietary gasketed structural framing for minimal heat loss/gain and the lowest U-values.
Daylight and Views, Daylight
Provide daylighting for 75% of regularly occupied spaces, with another point for 90%. Duo-Gard systems deliver diffused daylight without glare or solar heat gain and without additional shading requirements.
Daylight and Views, Views
Provide outside views for 90% of regularly occupied spaces. Visibility and ventilating sections integrate easily into Duo-Gard's custom systems.
Innovation in Design (ID)
Innovation in Design
Recognize exemplary performance that goes beyond LEED's requirements and/or achieves innovative performance in other green building categories. New options include Lumira® insulating aerogel, IR coatings and BIPV panels. Duo-Gard's Daylight Modeling Service enables designers to explore scenarios for innovative solutions, and their consulting approach with designers, engineers and fabricators contributes to efficiency, aesthetics, performance and LEED certification.
