C o n t E n t s 36 Earth Rangers Centre Earthly Education 6 Chandler City Hall Chandler’s Catalyst A splashing outdoor water feature might seem like a frivolous luxury in a desert community like the Phoenix suburb of Chandler, Ariz. But Chandler City Hall’s courtyard waterfall, part of a condenser graywater reuse system, is just one example of the project’s sustainable strategies that harness natural resources while conserving water and energy. The City Hall complex, which opened in 2010, is part of a project designed to spur development in the deteriorating downtown district and create an urban environment that attracts pedestrians. Passive shading strategies, a high performance envelope, daylighting and an underfloor air distribution system all contribute to the annual energy use intensity of 57 kBtu/ft2. 4 HIGH 20 Twelve | West Urban Connections How do you foster vitality and development in an emerging urban neighborhood? The developers of Twelve | West, located in the West End area of Portland, Ore., sought to accomplish these goals with a sustainably focused mixed-use high-rise that offers shopping, dining, office space and apartments in one location. Major contributors to the project’s sustainability include extensive daylighting, efficient underfloor air ventilation with perimeter baseboard heating and passive chilled beams, natural ventilation via operable windows and rainwater reuse. The double LEED Platinum building, which opened in 2009, recorded an annual energy use intensity of 44.9 kBtu/ft2 during its first year of operation. PERFORMING BUILDINGS Spring 2013 The design team for the Earth Rangers Centre outside of Toronto approached the project with some lofty goals: to make the facility one of the most efficient buildings of its size in North America and to create a building that furthers the nonprofit organization’s efforts to educate children about biodiversity and adopting sustainable behaviors. The 63,000 ft2 building includes an animal habitat area and was toured by approximately 8,600 students and others in 2012. Thermal mass, a geothermal system coupled to radiant heating and cooling, building automation system and a reduced-size data center contribute to the building’s annual energy use intensity of 31.8 kBtu/ft2 · yr and 95 ENERGY STAR rating.
