Another way to achieve LEED certification points is to reuse building material and recycled material. For the Wister Education Center and Greenhouse this idea has been employed in several avenues but none as uniquely as in the use of Metasequoia shingles.
In order to build the Alice Paul Hall (opened in 2005), a grove of Metasequoia glyptostroboides, dawn redwood, was removed from the area beside the south end of Mertz Hall. These twelve trees were harvested by Citilog and milled into shingles.
Citilog takes trees that have fallen down, are being removed as part of a construction project, or are saved from a demolition project and creates finished wood products such as furniture, flooring, and architectural millwork. Their mission is to “save trees from being dumped into landfills, cut for firewood, or ground up for mulch. In the process, they provide a valuable source of quality lumber, cabinetry, millwork and a wide variety of finished wood products.”
For the Wister Center, we were able to use 381sq. ft. of the Metasequoia shingles and used a 100 sq. ft. of cedar shingles to complete the job. We are amused to think outside of China, we may be the only place to have used Metasequoia in this way.
