Reference
Description
Article describing the importance of air sealing, insulation, and roof ventilation in reducing the likelihood of ice dam formation on roofs in cold snowy climates.
Case Study
Description
Case study describing an experiment to build and instrument unvented test roofs using air-permeable insulation in a cold climate and to analyze the moisture effects over time.
Reference
Description
Article from Montana State University Extension explaining how proper insulation techniques can greatly reduce the risks of ice dams on roofs in cold climate zones.
Case Study
Description
Case study describing a DOE Zero Energy Ready Home 2017 Housing Innovation Award winner that scored HERS 41 without PV and 8 with PV.
Reference
Description
A structural insulated panel (SIP) roof has no embedded lumber in the structure, and therefore nothing substantial for attaching PV array and solar hot water mounts. Single or double lumber splines could be put into the panels, or I-joists at 4-foot intervals could be added.
