Structural Insulated Panels

Structural Insulated Panels (SIPs) are prefabricated building materials used in residential construction in Alaska. This project prepared resources for homeowners who want to learn about SIPs, where they are used in cold climates, and considerations for Alaska.

This video gives an overview of building with SIPs in Alaska.

Designs for Rural Alaska Walls Monitoring CCHRC demonstration homes for efficiency and moisture infiltration several years after construction.
Safe Effective Affordable Retrofits Testing a new batch of wall systems that can provide affordable retrofit options.
Energy Recovery Ventilators (ERVs) in Cold Climates Energy Recovery Ventilators (ERVs) are whole house ventilation systems that exchange stale indoor air with fresh outside air, recovering both heat and moisture from the indoor air to save energy. They have the potential to improve indoor air quality in a cold dry climate like Interior Alaska.
Thermal Mass Study Thermal mass is the ability of a material to absorb and store heat energy, which can be useful when it comes to cold climate housing. This project clarifies the role of thermal mass in housing and includes a literature review and energy modeling with IDA Indoor Climate and Energy (ICE) software.
Permafrost Foundations CCHRC worked with the U.S. Army Cold Regions Research and Engineering Laboratory to pair information on permafrost soils with optimal foundation designs.
