https://www.journalmtc.com/index.php/mtcj <p>The Mass Timber Construction Journal is a peer-reviewed international online journal, dedicated to high quality research in Mass Timber Construction (MTC). The journal was created to fill an identified gap in the research publishing market. The editors found it difficult to publish MTC research in other journal publications due to a lack of concentrated peer-reviewers, editorial staff and researchers who are the leaders in the MTC field.</p> Mass Timber Construction Journal en-US Mass Timber Construction Journal 2209-2579 <p>The Author (on behalf of any and all co-authors) hereby assigns to MTCJ (hereafter known as the Publisher) the copyright to the Contribution named above; whereby the Publisher shall have the exclusive international rights to publish in any and all media the said Contribution and translations of it wholly or in part throughout the World under the provisions of this agreement.

Various studies have shown that optimizing the building envelope can significantly improve energy efficiency and provide cost savings. In the U.S., residential housing accounts for about 21% of the total energy use, presenting a substantial opportunity for energy reduction through retrofitting solutions. This research focuses on evaluating the life cycle assessment (LCA), hygrothermal performance using WUFI simulations, and thermal resilience of three distinct residential building envelope systems: Structural Insulated Panels (SIPs), a bio-based Cross-Laminated Timber (CLT) system, and a conventional stick-built system with continuous insulation. These systems are chosen based on their common applicability to the climate conditions and the sustainability demand of the materials. The benefits and limitations in terms of carbon emission, and energy efficiency of each system are evaluated to aid further development of sustainable and energy-efficient building envelope.</p> <p><br><strong>Keywords:</strong> Life-cycle Analysis (LCA), Building Envelope System, Energy efficiency, Thermal Resilience.</p> Shaghayegh Kurzinski Shayan Mirzabeigi Bryce Riccitelli ##submission.copyrightStatement## 2025-05-02 2025-05-02 8 1 1 11
