Safe & Effective Exterior Insulation Retrofits

Spray Foam InsulationCCHRC has summarized our latest findings on wall retrofits in a research snapshot. We studied various retrofit techniques over the last two winters in a trailer outfitted with 9 different test walls--each with unique combinations of interior and exterior insulation, some with vapor barriers and some without. Researchers asked two main questions: is there a minimum thickness of exterior insulation that can be added to prevent moisture problems, and will adding exterior insulation create a double vapor barrier effect by trapping condensation in the wall cavity?

The Alaska Consumer Guide to Home Heating

Consumer Guide to Home HeatingCCHRC researchers recently completed a guide that walks consumers through different types of home heating systems. The in-depth publication, created for the Alaska Housing Finance Corporation, covers heating appliances, distribution systems, and domestic hot water systems that are common in Alaska. It provides information and tools to help homeowners make informed decisions on heating appliances.

Evaluating Window Insulation

Movable Window Insulation ReportCCRHC tested eight types of common window insulation treatments during a Fairbanks winter to see how they handled heat loss and moisture buildup. Each window insulation was evaulated based on six criteria, so homeowners can select insulation based on factors most important to them. Exterior insulation methods, like shutters and storm windows, tended to perform the best and have the fewest condensation problems.

UAF Sustainable Village

CCHRC Research and Testing FacilityCCHRC is partnering with the University of Alaska Fairbanks to develop a sustainable student village that includes a cluster of super energy-efficient homes with shared open space, renewable energy sources, and a community garden. The village will be on University property adjacent to CCHRC’s research center off Fairbanks Street. The first cluster of buildings will be constructed in Summer 2012. It will be as much a research project as a development, where students, faculty, and departments at UAF will work with CCHRC building scientists to improve on each iteration of the Village over the coming years.

Ground Source Heat Pump and Solar Thermal

Weller LoopsCCHRC and the Alaska Center for Energy and Power conducted the first in-depth assessment of ground source heat pumps (GSHP) in Alaska. GSHPs extract heat from the earth (with the help of electricity) and use it for space or water heating. The study found that GSHPs offer an economically viable heating option in Alaska locations with high heating costs and relatively low electric costs, such as Juneau, Seward, and Fairbanks.

CCHRC researchers are also studying the performance and impacts of a hybrid GSHP-solar thermal system at Weller Elementary School in Fairbanks. CCHRC also plans to install a GSHP at its facility in Fairbanks in 2012 to offset oil consumption.
