Help Increase Energy Efficiency with DuPont Weatherization System Products
When it comes to designing and building homes and commercial spaces that are more energy efficient, you can count on DuPont Weatherization System products to help you meet your goals. By working together to seal the building envelope, these innovative building products can have a positive impact on energy efficiency in three key ways: reducing air leakage; reducing air infiltration through wall cavities; and protecting against bulk water intrusion and air-transported moisture.
HVAC Systems Use Most Energy
According to data from the U.S. Department of Energy, HVAC represents the largest share of energy use – on average 37% -- by all building types. Air leakage can have a significant impact on the sizing and effectiveness of HVAC systems.
Advantages of Sealing the Building Envelope
DuPont Weatherization System products are designed to work together as a complete system to help seal the building envelope. This creates an air barrier system that not only improves the building envelope by reducing air infiltration and exfiltration, but also reduces unwanted air leakage through the wall cavities helping to maintain the installed R-values of insulation [.pdf]. A well designed building envelope helps to reduce the load requirement on the HVAC system, allowing for proper HVAC sizing and potentially lowering the initial equipment cost. In addition, the lower base loading on the HVAC system due to infiltration migration makes its use more effective, helping owners to save energy and lower operating costs while keeping occupants comfortable year round.
Sealing the building envelope with DuPont Weatherization System products also helps protect structures against bulk water intrusion and air-transported moisture, two factors that can dramatically reduce the effectiveness of fibrous insulation, as well as lead to wood or metal degradation.
Recognition for Sustainable Buildings
Choosing DuPont Weatherization Systems products can help your residential and commercial projects be officially recognized as sustainable buildings. For example, DuPont Weatherization System products help meet the requirements for multiple Energy Star® [.pdf] programs and the National Green Building Standard™, and may contribute toward U.S. Green Building Council LEED® (Leadership in Energy and Environmental Design) points. DuPont Weatherization Systems also appear in the CSI GreenFormat™ database, a listing of products that help contribute toward sustainable design and building.
