Insulation Monitoring in Tununak

Insulation Monitoring in Tununak This project looks at the moisture performance of a thick truss wall with blown-in fiberglass insulation over 2 years in a wet, windy climate. With cold winters and wind-driven rain and snow, the climate of southwest Alaska is harsh on houses. The most likely point of building failure is moisture-driven, as…

Engineering Research Center Planning

Engineering Research Center Planning The Alaska Center for Energy and Power is initiating an effort to develop an Arctic Engineering Research Center (ERC) in Alaska that would work with communities facing challenges of a warming climate. The ERC would provide tools and resources to help communities decide whether or not to relocate. CCHRC is advising…

Secure and Resilient Power Generation in Cold Regions

Secure and Resilient Power Generation in Cold Regions Working in collaboration with Construction Engineering Research Laboratory and Cold Regions Research and Engineering Laboratory (CRREL) staff, researchers with the University of Alaska Fairbanks (UAF) and the Cold Climate Housing Research Center will carry out a techno-economic assessment of new energy options at Fort Wainwright. Researchers will…

Designs for Rural Alaska Walls

Designs for Rural Alaska Walls CCHRC has used spray polyurethane foam insulation to build affordable demonstration homes in rural Alaska since 2009. While spray foam has a high insulation value and competitive shipping cost, it requires skill to install and any errors can result in a drastic drop in energy efficiency of the building. This…

Evaluating Window Insulation

Evaluating Window Insulation CCHRC evaluated eight types of common window insulation methods, including interior and exterior types of moveable insulation. Windows are an expensive part of the building envelope to replace, so people in cold climates often resort to cheaper methods, such as shutters or curtains, to reduce heat loss. Others may already have high…

Wood Storage Best Practices

Wood Storage Best Practices Burning wet wood contributes to harmful PM2.5 pollution, a problem that has plagued the Fairbanks airshed over the past few winters. Burning dry wood produces fewer emissions and more heat energy, a benefit to both homeowners and all borough residents. CCHRC completed a study on multiple wood storage methods to see…

Geopolymer Cements

Geopolymer Cements CCHRC is performing a high level analysis of the local market potential for geopolymer cements. The analysis includes an assessment of available local materials, potential of local product manufacturing, and potential economic feasibility. This is a sister project to the Magnesium Phosphate Cement Testing and Application project funded by Alaska Housing Finance Corporation…

Interior Shutter Evaluation

Interior Shutter Evalution CCHRC worked with Fairbanks builder Thorsten Chlupp to evaluate an interior window shutter system that was designed to reduce heat loss through window while preventing moisture to condensate between the window and the shutter. The scope of work involved the instrumentation of the new interior window shutter design and monitoring performance over…
