Case Studies
This library contains research reports produced by the Building America program and other building science resources used to support this Solution Center. The materials cover both new construction and existing homes. Use the search box and/or the filters to explore hundreds of residential building resources. Access to some references not produced by Building America may require purchase from the publisher. Documents are listed alphabetically. While we continually update our database, links may have changed since posting. Please contact our webmaster if you find broken links.
