Projects

DOE Energy Efficiency and Renewable Energy Projects These projects seek to reduce and stabilize energy costs of tribal buildings in four different communities in Southwest Alaska.
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.
Three-Stage HRV Evaluation This project looked at the effectiveness of various frost protection strategies and their effect on energy efficiency and indoor air quality.
Frost-Protected Shallow Foundation Study Frost-protected shallow foundations rely on placing enough insulation outside of a shallow foundation to protect it from heaving due to seasonal freezing. Temperature sensors were installed at two houses with these foundations to measure the thermal regime of the soil.
Ground Source Heat Pump & Solar Thermal at Weller School CCHRC and the Alaska Center for Energy and Power conducted the first in-depth assessment of ground source heat pumps in Alaska. We studied a system at a local elementary school that uses warmth from the ground to heat the building, and recharges the soil with solar energy in the summer.
