Objective:

The primary objectives in Phase II are:

  • To develop, detail, and construct a full-scale building using green oak pallet cants as structural members.
  • To monitor, record, and analyze the demonstration project for structural, acoustic, and thermal performance over a two-year period as the green oak members dry.
  • To disseminate our findings widely through multiple digital media platforms, peer reviewed publications, design award programs, and programs recognizing the integration of pedagogy and practice.

Approach:

The objectives of Phase II will be explored through the design and construction of a full-scale demonstration project using green oak pallet cants as structural members. The demonstration project will be monitored for a period of two years during which time the green oak frame will fully dry. Monitoring will include frequent examination of joints for structural integrity, examination of interior details for acoustical performance, and examination of exterior details for thermal performance – all of which are challenged by the shrinking of the green oak structural members as they dry. Of secondary interest will be the performance of the untreated green oak siding cut from the cants. Weathering of the siding will be monitored visually and with moisture meters.

Expected Results:

The full-scale demonstration project will serve both to validate the findings in Phase I and as a critical built example that will facilitate adoption of green oak pallet cant technology by design professionals and building code officials.
