DuPont recently announced its 5-story, 220,000 square foot office building at its Chestnut Run Plaza facility has achieved LEED (Leadership in Energy and Environmental Design) Gold certification. The LEED green building rating system -- developed and administered by the U.S. Green Building Council -- promotes design and construction practices that increase profitability, reduces environmental impacts and improves occupant health and well-being.
DuPont Vice President and Chief Sustainability Officer Linda Fisher and DuPont Vice President and Chief Engineer Karen Fletcher joined Delaware DNREC Secretary Collin O’Mara and Executive Director of the Delaware Valley Green Building Council Janet Milkman, in an event to unveil the LEED Gold plaque.
“Receiving the LEED Gold certification symbolizes all the hard work from our employees that create everything from the reception desk made of DuPont™ Corian®, to the components of the solar panels on the roof,” Linda said. “This building represents how DuPont is applying its integrated science to making buildings more sustainable, and how DuPont uses innovation in everything we do.”
Sustainability is a key element of the building’s design, including a green roof complete with a state-of-the-art solar array that offsets energy needs. At least 50% of the wood-based materials used in construction of the building are certified wood from sustainable forests, and 20% of the materials used in construction of the building originated within 500 miles of the facility.
In addition to an extensive use of recycled materials, the building incorporates advanced technology into its function and aesthetics, such as waterless urinals, energy efficient LED lighting and HVAC systems. Over 65% of the building’s glass exterior allows extensive use of natural lighting. The building’s “white roof” is made of DuPont™ Elvaloy® that reflects the sun and reduces the load on cooling systems in the summer months saving on energy bills. The carpeting is made from DuPont™ Sorona® renewably sourced fiber. Its production reduces energy consumption by 30% and carbon dioxide emissions by 63%.
More than 20 DuPont products are incorporated into the building’s structure, electronic systems and décor including:
- DuPont™ Corian® solid surface material used as siding on the building’s exterior, countertops in dining areas and multiple decorative applications;
- Zodiaq® quartz surfaces for interior surfaces, kitchen countertops and vanity tops;
- Tyvek® CommercialWrap® used to help prevent air and water infiltration;
- Solar panels from DuPont Apollo, Ltd.;
- SentryGlas® ionoplast interlayer.
