When the SLC was in its initial design stages, the architect's goal was to have the building reach
LEED Silver. Once completed, they implemented various different design strategies to achieve this and when the building finished its construction, it was awarded LEED gold. The building features three
green roofs, water conserving
plumbing fixtures, roof and ground water collection systems that harvest
storm water, concrete structure, mechanical features, automated lighting controls and a strategically designed glass
facade. The three green roofs are located on the top of the building, on a low sitting roof at the entrance of the building, and one on the roof of an attached bridge. The green roof located on the main roof of the building covers 50% of the surface. The SLCs roof and ground water collection systems as well as select plumbing fixtures help the building achieve LEED gold status. The building's storm water collection system stores water in concrete tanks located in the basement and are used throughout the building.
Greywater from the building is used to irrigate the green roofs and is also used in urinals and
water closets, the plumbing fixtures in the building were selected with the purpose of using the least amount of water possible. The main material used in construction of the SLC is concrete, it was chosen because it provides good
acoustic absorption and works well with the buildings in floor heating and cooling pipes. Concrete that can be seen on the inside of the building incorporates
fly ash which helped the building achieve LEED gold. The buildings mechanical features were chosen for their efficiency and sustainability, the central heating system distributes air using two condensing hot water boilers designed to operate at 94% efficiency and is based on a low temperature hot water heat distribution system. The cool water system the building runs off is supplied directly from the universities central plan, during the cooler months of the year outside air is brought into the building through air handlers to regulate temperatures. Outdoor air is constantly recirculating through the building and is measured by units that take readings of
carbon dioxide from various zones in the building. The glass façade of the SLC is lightweight and transparent, it is an excellent design element that provides privacy and contributes to the sustainability of the overall building. The glass around the building is
three-paned glass and is fritted with random geometric shapes that we specially designed for the project. The triple glazed glass and fritting reduces the weight of the material and lowers
energy consumption, they also reduce glare and reflect heat which helps keep the building cooler during summer months. == References ==
