Weatherization of a building is implemented in a variety of ways, but focuses on tightening the building envelope such that less air and heat are able to transfer between the inside and outside. A leaky building can feel uncomfortable, and the effort to maintain a stable indoor climate can drive up energy costs. By improving building insulation, upgrading doors, windows, and other exit points, providing ventilation, and controlling energy transfer across the building envelope, weatherization can improve temperature and humidity control, thus improving occupant comfort while managing energy expenditure.
In an ongoing project with funding from the U.S. Environmental Protection Agency, Energy Studies and Buildings Laboratory and the Biology and the Built Environment Center, along with Oregon Research Institute collaborators, are investigating the effect of home weatherization on microbial ecology, indoor air quality, homeowner behavior, and ultimately occupant health. We are nearing the completion of the project and expect to publish soon – stay tuned for an update with our findings.
