This building boasts an extensive green roof along with a deck layered with various shades and textures. In September 2005, the rooftop garden was extended by 2600 square feet using green roof technology. A carpet made up of different types of sedums was installed directly on to the roof just east of the existing deck. Like cacti, sedums are succulent plants that have fleshy leaves and stems for storing water and a waxy coating to reduce evaporation. These adaptations make them ideal candidates for green roofs. The Xero-Flor light-weight, vegetated mat is similar to sod and can be cut to fit any size of roof. It is laid on top of a fleece mat that holds the planting media and roots. Not only does this green roof provide added energy savings, it also cools the surrounding space and holds much of the rainwater that falls on it.
Its grand scale lends a natural aspect to the rooftop space and even two of the 100 square foot heritage skylights have been included in the greening.
