Building Envelope Systems for LEED® Certified Building Designs

A-14s

DuPont™ Tyvek® weather barriers and other products help support LEED® certified* building designs.

DuPont is a proud participant in leading sustainability initiatives, and has been a member of the U.S. Green Building Council (USGBC) for many years.  This nonprofit coalition of leaders from across the building industry is dedicated to promoting sustainable buildings that are also profitable, and healthy places to live and work. 

USGBC developed LEED® (Leadership in Energy and Environmental Design) to establish a common standard of measurement, and promote integrated, whole-building design practices.

How DuPont™ Building Envelope System Products Can Contribute

DuPont™ Building Envelope System products help you create more sustainable buildings.  They work together to seal the building envelope, which can help increase energy efficiency, protect against water damage, and provide improved comfort and indoor air quality for occupants.

By preventing bulk water intrusion and allowing water that does get in to evaporate and escape as vapor, these innovative building products also help to reduce the possibility of the formation of mold within the wall assembly, which aids in for a healthier building environment.  In addition, the full system includes low-VOC materials, which can help in maintaining better indoor air quality.

Although no single product can create a LEED® certified building design, using DuPont™ Building Envelope System products for your residential or commercial structures can help contribute toward LEED® points in several credit categories.

LEED® NC  (New Construction and Major Renovations)

A continuous air barrier is a mandatory requirement in ASHRAE 90.1 2010, the model energy code for commercial buildings.  The latest LEED version (LEED v4, just approved July 3, 2013) lists ASHRAE 90.1 2010 as a prerequisite (ASHRAE 90.1 2007 was the prerequisite for LEED v3).

The implications are that a building cannot apply for LEED certification under LEED v4, unless it meets the mandatory requirements of ASHRAE 90.1 2010 (which includes a continuous air barrier).

In addition to being a prerequisite, a continuous air barrier could contribute to additional LEED points in the following categories:

* Energy & Atmosphere (EA)

DuPont™ Building Envelope System products can help achieve an airtight building envelope, which can help reduce HVAC energy use, contributing toward LEED® points in the EA- Optimize Energy Performance category.

* Indoor Environmental Quality (EQ)

DuPont™ Tyvek® weather barriers protect installed absorptive materials, such as insulation and exterior sheathing, from moisture damage during construction, while also allowing the drying of incidental and construction moisture.  This helps to reduce the potential for the growth of mold in the wall system, which could negatively impact indoor air quality.   This may help contribute toward LEED® points in the EQ -Construction IAQ Management Plan category.

The complete system of DuPont™ Building Envelope System products includes adhesives and sealants that are low-VOC materials, which helps in maintaining better indoor air quality.  This may help contribute toward LEED® points in the EQ - Low Emitting Materials category.

LEED® for Homes

* Energy & Atmosphere (EA)

DuPont™ Building Envelope System products can help achieve an airtight building envelope, which can help reduce HVAC energy use. This can help contribute toward LEED® points in this category.

* Indoor Environmental Quality (EQ)

Installing a DuPont Building Envelope System between the garage and the living space helps prevent air contaminants in the garage from entering the living space.  This can help meet garage separation recommendations, and may contribute toward LEED® points in this category.

* Materials & Resources (MR)

All adhesives and sealants that are part of the DuPont™ Building Envelope System product line meet emission specifications as low-VOC materials, as outlined by LEED®.  This can help contribute toward LEED® points in this category.
