Wood structures can endure for centuries if they remain sufficiently dry. Many of the challenges of using wood as a structural material (such as mold growth, wood decay, corrosion of fasteners, and dimensional instability) arise from excessive moisture levels or large changes in moisture content.
Dr. Glass leads the Building Moisture and Durability Team within the Building and Fire Sciences Research Work Unit at the Forest Products Laboratory. His research focuses on the relationships between moisture, energy-efficiency, and durability in residential and non-residential wood-based buildings. Primary research objectives include
- Durability of energy-efficient buildings
- Building envelope performance
- Moisture management in buildings
- Heat, air, and moisture transfer
- Wood-moisture relations
- Hygrothermal properties of wood products
- Interior and exterior moisture loads
- Instrumentation for monitoring moisture levels in building assemblies
Dr. Glass conducted his doctoral research in the Department of Chemistry at the University of Wisconsin-Madison. He investigated how surfactant films at the gas-liquid interface control gas uptake and evaporation of water. These studies contributed to understanding chemical reactions that occur in sulfuric acid droplets in the upper troposphere and lower stratosphere, which affect ozone levels.
Why This Research is Important
The sustainability and health of America’s forests depend on sound conservation practices, including utilization. Efficient use of wood as a green building material is important for climate change mitigation because wood products store carbon for as long as the building exists. The longer the service life, the greater the benefit. Wood products require much less energy to process than other building materials such as steel or concrete, and use of wood produces less air pollution, solid wastes, and greenhouse gases. Efficient wood utilization also reduces the risk and impacts of wildfire, provides incentives for private landowners to maintain forest land, and provides a critical source of jobs in rural America. These benefits hinge on efficient and proper use of wood in construction, and moisture control is essential because of wood’s vulnerability to moisture problems. Moisture management is also critical because excessive dampness in buildings has been linked to negative health effects.
