ARIS Development

Project Page

The Alaska Retrofit Information System (ARIS) is a wealth of data on housing in Alaska, including housing size, cost, energy use, airtightness, and more for over 75,000 homes across the state. ARIS provides CCHRC and AHFC valuable information about the economics of energy efficiency, the state of housing in various communities, and the success of retrofit programs in various regions.

This project builds a web-based user interface for data collection, reporting, and analysis.

Weatherization & Rebate Program Impacts Report An overview of the impacts of the Home Energy Rebate and Weatherization programs and success in accomplishing legislative goals:
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.
