National Grid plc has unveiled plans for the future home of its Sustainability Hub, a 2,200 square-foot facility centrally located within the company's smart grid pilot area in Worcester, Mass. The space, located at 912 Main Street, has been donated by Clark University and will connect the community and customers under one roof to provide interactive education about energy efficiency and emerging technologies. It is an integral part of the company's smart grid pilot -- now known as the Smart Energy Solutions Program -- for 15,000 customers who choose to participate. National Grid's program, which was developed in partnership with customers, the city of Worcester and other key parties, provides participating customers with a new level of choice and control over their energy use through advanced technology, with the goal of empowering customers to save energy, potentially increasing electric service reliability and improving response to power outages. Sustainability Hub Features: National Grid's Sustainability Hub will house interactive exhibits and educational materials to demonstrate the advanced technology offered as part of the program that will help customers maximize energy savings. This includes helping customers "try-on" in-home energy use displays, programmable thermostats, and dynamic pricing options. Local university student ambassadors from Clark University, Holy Cross and Worcester Polytechnic Institute will help staff the Hub, creating cooperative learning opportunities for both local customers and students. Students also will participate in various internship opportunities under the pilot. Six students from the Claremont Academy's Art Studio have designed an abstract mural for one of the Hub's outside walls that incorporates a conceptual map of the local geography and combines a community, energy and sustainability message. Local artist Jen Swan will transfer the concept onto the outer wall. Demonstrations offered in the Hub will include energy efficiency treatments such as windows, spray-in insulation and tankless water heaters. Displays on controllable and programmable appliances will be available. Exhibits on advanced meters, smart grid electricity system devices and renewables will be on-hand, and an interactive energy management tool will be made available to Hub visitors so they can learn more about energy choice. The Sustainability Hub will feature a community exhibit area that will showcase the many efforts by local organizations that under way throughout the city. When completed during the fall of 2013, the Sustainability Hub will be fully renovated with sustainable materials and energy-efficient equipment donated from vendors including Mitsubishi, GE/Phillips, Blue Hive and Verizon. An electric vehicle charging station will be installed just outside of the facility, which was provided through ChargePoint, through a grant from the U.S. Department of Energy, and is the first street-side electric vehicle charging station to be installed in Worcester.
