Non Technical Summary
Information on new wood building systems and products will be generated by our work in their problem area. Considerable effort will focus on energy efficiency in construction.

Objectives Summary
The objective of research conducted in this problem area will be to: (a) develop analytical models of wood structural systems performance, and (b) develop accurate methods to determine performance under a range of service conditions to support improvements in design and management decisions regarding maintenance, retrofit, and repair methods.

Approach Summary
Planned attainments: 1) Investigate the potential of utilizing various energy harvesting technologies in wood structures; 2) Development of informaton on use of green building strategies with wood structures; 3) Develop design concepts for wood structures that include emphasis on disaster mitigation/design for extreme events; 4) Develop design concepts that focus on energy efficiency.
