Combustion Air/CO Study

Project Page

Combustion BoilerCCHRC, through a grant from Alaska Housing Finance Corporation, conducted a combustion air evaluation in the Fairbanks area. The purpose of the study was to assess sufficiency of current practices in combustion air supply for atmospherically vented heating appliances, and assess the performance of power-vented appliances. Each house was be measured and evaluated to determine:

  1. house and combustion appliance zone (CAZ) surface area and volume;
  2. common wall surface area and leakage;
  3. air leakage of house and CAZ; and
  4. the amount of combustion air (vented and ambient).

CCHRC staff met with individuals who are reviewing codes for the City of Fairbanks Code Review Board and presented data collected from this study on combustion air requirements for oil-fired boilers. This information was incorporated in new code requirements and adopted as an amendment to the 2000 International Mechanical Code.

BrHEAThe with Air Source Heat Pump CCHRC is testing how an air source heat pump can be integrated into a heating and ventilation system in high efficiency homes.
BrHEAThe Evaluation In an effort to address these issues CCHRC developed the BrHEAThe system in 2011. BrHEAThe is a combined heating and ventilation system which uses one distribution system to provide fresh air and space heating to high-performance homes in cold climates.
Energy Recovery Ventilators (ERVs) in Cold Climates Energy Recovery Ventilators (ERVs) are whole house ventilation systems that exchange stale indoor air with fresh outside air, recovering both heat and moisture from the indoor air to save energy. They have the potential to improve indoor air quality in a cold dry climate like Interior Alaska.
Kenai Indoor Air Quality Study This project examined the most common causes of indoor air quality problems in Southcentral Alaska by monitoring 100 homes for carbon monoxide, carbon dioxide, temperature, relative humidity, and radon.
