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…

Passive Refrigeration

Passive Refrigeration This project looked at ways to use the cold temperatures during Alaska winters to lower the electrical demands of residential refrigerators and freezers. CCHRC worked with industry partners to test a prototype of a passive refrigerator/freezer that used electricity only when the outdoor air temperature is too warm to sustain refrigerator temperatures. The…

Mold Survey

Mold Survey In early March, 2003, we were contracted by the HUD Office of Native American Programs (through Magna Systems) to do a rapid survey of mold problems in Alaska Native Housing. We contacted 73 of 88 regional or village housing authorities in Alaska and documented over 1700 apartments or homes that had some level…

Evaluating Residential Heating Systems

Evaluating Residential Heating Systems CCHRC, through a grant from Alaska Housing Finance Corporation, contracted with Arctic Energy Systems (AES) to measure the actual design heat load of houses by monitoring the runtime of the furnace in relation to outdoor temperatures. The study monitored 20 houses in the Anchorage area during the very cold weather. The…

Wall Moisture Studies

Wall Moisture Studies CCHRC studies various building envelope designs in the Mobile Test Lab, a trailer with nine test wall bays that allows us to test multiple insulation strategies under the same conditions. During active studies, we simulate conditions of a “normal” house inside the Mobile Test Lab. Sensors embedded in the walls record temperature,…

thermal storage

Thermal Storage Technology

Thermal Storage Technology Assessment This technology assessment was sparked by a strong interest in using thermal storage to supplement home heating systems. Thermal storage can take many forms: water storage tanks that allow residents to burn wood more efficiently; a storage tank for an electric heating system to enable off-peak power use; storing heat gathered…

Structural Insulated Panels

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.

Fuel Use Monitoring

Fuel Use Monitoring CCHRC researchers are testing several methods of monitoring fuel use at the household level. The study, funded by the Alaska Housing Finance Corporation, is an attempt to identify a cost-effective and accurate method to monitor heating oil consumption across Alaska. That data could then be used to evaluate whether state energy efficiency…

Three-Stage HRV Evaluation

Three-Stage HRV Evaluation In Alaska and Canada, the main defrost strategies for heat recovery ventilators (HRVs) involve recirculating return air across the heat exchanger core and back into the supply air for the house. In cold climates, this type of frost protection system can undermine ventilation standards. To overcome this issue, continuous ventilation systems such…
