Thermal Mass Study

Thermal Mass Study Thermal mass is the ability of a material to absorb and store heat energy, which can be useful when it comes to cold climate housing. This project clarifies the role of thermal mass in housing and includes a literature review and energy modeling with IDA Indoor Climate and Energy (ICE) software. The goal…

Combined Heat & Ventilation

BrHEAThe Development & Evaluation BrHEAThe is a combined heating and ventilation system designed at CCHRC for providing space heating, domestic hot water, and fresh air for small, airtight, and energy efficient homes. The main goal of BrHEAThe is to ensure adequate indoor air quality – by tying ventilation to the heating system, BrHEAThe ensures that…

Garage Wall Analysis

Garage Wall Analysis Roughly half the homes in Fairbanks and Anchorage have an attached garage. Many garages are filled with exhaust from vehicles and heating appliances as well as VOCs. The current building technique in Alaska is to build an exterior wall between the home and garage sealed with an air/vapor barrier, such as 6…

Little Ventilation Project

Little Ventilation Project This project looks at ventilation systems that can improve indoor air quality in small homes while limiting energy use. While the average home in much of rural Alaska is smaller than 1,500 square feet, current ventilation systems are not always well-suited for thise size homes. Because they sometimes deliver too much cold…

Slab-on-Grade Foundation Best Practices

Slab-on-Grade Foundation Best Practices On-grade foundations are a popular design in Interior Alaska. This project uses modeling software to address these questions: A shallow frost-protected foundation  relies on heat loss to the ground to keep the soils beneath the footing above freezing. What’s the optimal amount of subslab insulation to use to achieve this goal while…
