ARIS Development

Project Page

The Alaska Retrofit Information System (ARIS) is a database of information on housing in Alaska owned by the Alaska Housing Finance Corporation (AHFC). It also includes data about housing size, housing cost, energy use, airtightness, and savings from energy retrofits. ARIS provides CCHRC and AHFC valuable information about the economics of energy efficiency, the state of housing in various communities and regions, and the participation by political district.

This project integrates AkWarm, weatherization and energy rebate program data, data processing and reporting. It develops a web-based user interfaces that allow for data collection, reporting and analysis to happen remotely and consistently.

A home in Fairbanks, Alaska, retrofitted in 2008. These photos illustrate the temperature of the exterior walls in winter. On the left, the “before” photo; on the right, the “after” photo.


AkWarm Updates CCHRC is updating AkWarm, the software used to rate the energy efficiency of Alaska homes, to account for renewable energy, heat loss characteristics, and regional variations in climate and energy.
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.
Rebate & Weatherization Program Evaluation Audit Process This project evaluated AHFC's weatherization and rebate programs to determine outcomes and recommend improvements.
PM 2.5 Reduction Policy CCHRC developed a model to estimate PM2.5 emissions from residential heating sources in Fairbanks and evaluated a variety of policy options aimed at reducing emissions, finding that these efforts could cut emissions in half.
4-5 Star Plus Energy Rated Homes Survey & Analysis Ivan Moore Research (IMR) of Anchorage conducted a customer survey of Four Plus and Five-Star Plus homes to determine customer satisfaction and understanding of building components.
