Green roofs provide a myriad of environmental and financial benefits to a building and its owner. They can provide a pleasing outdoor aesthetic in an urban environment, as well as provide stormwater management and energy savings in an arid climate. California State University San Marcos completed a new University Student Union in 2014 that included a 2,540 square foot Live Roof system on its upper terrace. Supplier, contractor, and facilities team members were interviewed to analyze the success of the project from several viewpoints. The green roof was found to meet the University’s goals on aesthetic design, energy, and stormwater management through its selection of material and local flora. Challenges for the implementation of the green roof included design coordination and installation logistics. A net present value of $946 was calculated based on figures provided by the University, representing a cost-benefit over a standard white roof. This project demonstrates a successful implementation of a green roof in an arid climate.
