Document covering basic moisture control principles in the design of above-grade building enclosures; driving rain as a moisture load on walls; a classification system of the various rain control strategies available for walls; and good design practises for walls.
This report will review, and summarize the current state of understanding and research into enclosures with higher thermal resistance, so-called “High-R Enclosures.” Recommendations are provided for further research.
Case study describing a 2013 DOE Building America Top Innovation for the installation of rigid foam insulation on the exterior of home roofs and walls as a thermal, air, and moisture barrier.
Guide describing how to install flashing that is integrated with air and water control layers around piping, vents, and other wall penetrations as part of an exterior wall retrofit.
Guidebook providing useful examples of high performance retrofit techniques for the building enclosure of wood frame residential construction in a cold and somewhat wet climate.
Report explaining moisture-related concerns for high R-value wall assemblies and discusses past Building America research work that informs this study.
Report exploring four questions to determine the level of risk associated with adding drained exterior insulation to the exterior of an existing home during an energy retrofit.
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.
Report describing steps homeowners can take to improve the indoor air quality in their home, including ventilating, preventing pests, and reducing pollutants in the home.
Document describing a hygrothermal modeling study, including all of the US climate zones, a range of interior humidity levels and numerous arrangements and types of insulation.
Report about the fundamental concepts that must be understood at the planning or initial nspection of existing homes regarding surface and ground water management.
