Focus on Durability, PATH Research at the National Institute of Standards and Technology



Christopher C. White


Researchers at NIST in collaboration with the PATH-D program have been working to improve the durability of residential home construction. These efforts have been in two focus areas: working with industrial consortia to implement greatly improved methodology for the determination of service life of products. This effort has involved the implementation of a reliability-based approach, which integrates both controlled indoor and monitored outdoor exposures into a database that is used to modify and improve a model of the dose-damage relationship. This model is then used to predict the service life of the materials all achieved in greatly reduced time frame compared with traditional outdoor exposure. The second focus is to develop a web-based integrated decision support system that combines the service life predictions from the first effort with robust economic models to show homeowners the added value they can achieve by selecting more durable products.
