|Air Source Heat Pumps for Residential Baseboard Heating||CCHRC is working with utilities in Southeast Alaska to identify air source heat pumps that work for homes with baseboard hydronic heating. CCHRC is investigating the stats and availability of compatible technologies for residential applications in the U.S. and foreign markets.|
|Air Source Heat Pumps in Southeast Alaska||
ASHPs take heat from the outdoor air and use electricity to raise the temperature. Because they require less electricity than electric heating appliances, heat pumps could reduce heating costs for Southeast residents.
|ARIS Development||CCHRC manages the Alaska Retrofit Information System (ARIS) for AHFC. ARIS is a database of information on housing size, cost, energy use, and more for over 75,000 housing units in Alaska. It can be used as a tool for planning housing and energy policies and programs.|
|AVCP Bethel Housing||CCHRC is working with the The Association of Village Council Presidents (AVCP) to design two duplexes for flight school students in Bethel. The duplexes will highlight the integrated truss technology and energy efficient building strategies in a visible hub community, helping to publicly vet these approaches and serve as model homes in the region.|
|Combustion Safety Test Failure Analysis||This project investigates why buildings fail the combustion safety test and how to avoid these failures, in both new construction and retrofits. It includes a literature review, preliminary data analysis, education video, project planning, and test protocol prove-out.|
|Durable Envelopes for Cold Climates||
CCHRC is developing and testing building envelope designs that can withstand cold climates and healthy indoor humidity levels. The Mobile Test Lab has nine test wall bays, each with a different configuration of studs and insulation—including a control wall with fiberglass batt insulation.
|Fairbanks Nonprofit Retrofit Pilot||This pilot project helps Alaska nonprofits save money by making their buildings more energy efficient. The goal is to help the nonprofit sector substantially reduce its energy costs so organizations can spend more on their mission.|
|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.
|Ground Source Heat Pump Demonstration at CCHRC||CCHRC is testing a ground source heat pump at its facility in Fairbanks, part of a goal to shift to all renewable sources of energy and test the long-term performance of heat pumps in a subarctic climate.|
|HERS Software Development||CCHRC is researching and developing guidelines for AHFC staff to use when reviewing software for compliance with the Home Energy Rating System (HERS) standard.|
|North Slope Housing Prototypes||CCHRC is working with Tagiugiullu Nunamiullu Housing Authority to design homes in six North Slope villages. The homes feature a unique foundation system designed for the permafrost conditions in the high arctic.|
|Permafrost Foundations||CCHRC is working with the U.S. Army Cold Regions Research and Engineering Laboratory to study ways of pairing information on permafrost soils with optimal foundation designs.|
|Residential Indoor Air Quality Study||This project looks at new ventilation standards and recent IAQ research findings in ventilation to help inform homebuilders, architects, engineers, and other housing professionals.|
|Sustainable Northern Communities Monitoring||
The Sustainable Northern Communities program aims to develop energy efficient, affordable, healthy housing that fits the climate and culture of Alaska communities. SNC brings together local residents, tribal governments, state and federal agencies, housing authorities, and other partners. CCHRC monitors the prototype homes to troubleshoot and improve designs.
|Three-Stage HRV Evaluation||CCHRC is working with Fairbanks builder Thorsten Chlupp to study a heat recovery ventilator (HRV) with a ground-loop to preheat ventilation air.|
|Vapor Diffusion-Open Walls Study||
CCHRC monitored builder Thorsten Chlupp’s super low-energy home to see how the innovative systems performed in the Fairbanks climate. The house has super-insulated walls and foundation, an integrated heat storage system, and an open wall design that allows vapor to diffuse through.
