ped students can gain firsthand knowledge of the salt marsh habitat. As the project moved through the design phase, both one and two story schemes were analyzed to address the trade offs between creating a building with dispersed weight distribution versus one that minimized the exterior volume. Ultimately, the landform and soil bearing capacity mandated a onestory building. The bination of that layout, however, with the revetment, allowed for the creation of a barrier free facility with a strong connection to the site. This connection was further augmented by the creation of 14 exits at grade. The building has a 20 kW photovoltaic array on the south roof that produces an equal percent of electricity annually as is consumed by the building’s lighting system for the entire year. In addition, Save The Bay is working to partner with others to construct a wind turbine on the site. With an eye toward the future, the gasfired mechanical system is able to shift to biofuel or other renewable fuels. 4 Utilizing Power DOE 2 modeling in an iterative process, the building’s envelope and systems were optimized for energy efficiency and minimization of pollution contributions. The upgraded building envelope, high pe
