SOCIAL ECONOMICAL ENVIRONMENTAL DESIGN

GRADUATE HOUSING PROJECT Located on the west entry to campus on the edge of Lake Hartwell, SEED [social economical environmental design] Housing proposes a new living paradigm for graduate students and faculty. Many come to Clemson for the rural, laid-back atmosphere it provides, but there are few areas in which to enjoy this lifestyle as a residential community. By injecting life into the area with residents, Y Beach could become the missing piece of the “Clemson Experience.” SOCIAL SUSTAINABILITY To take advantage of the unique landscape, clusters of units are spread out to create smaller, close-knit communities distinct to the three site experiences of forest, lake and meadow. The location-specific combinations respond to existing vegetation, topography, views, privacy, and solar orientation. To encourage interaction with the landscape in this mild climate, outdoor spaces are given priority through offering three levels of green space: private terraces, shared courtyards, and public parks.

Y BEACH RECREATIONAL SITE

ECONOMICAL SUSTAINABILITY Scaled down indoor living offers economical benefits as well, which are crucial to the success of campus housing. Additionally, only two unit types – a single and a double – create the diverse combinations, making construction quick, low cost and easy without sacrificing uniqueness. The units consist of four exterior walls with a prefabricated core anchoring the center. The core contains all living functions and organizes the interior space. Passive and active design as well as CLT construction further support economic sustainability. ENVIRONMENTAL SUSTAINABILITY Smaller living spaces are also crucial to environmental sustainability, as they require significantly less energy. The highly insulated units are oriented North/South for optimal daylighting with controlled heat gain. Natural ventilation, a high efficiency geothermal heat pump, recycled materials, and CLT construction [a low-energy, low-waste and renewable method] all further this goal. PV panels and rainwater collection provide energy and water for all units. The entire development thus embraces a zero-energy concept as the future of sustainable campus housing.
