C o N t e N t s 18 Bosarge Family Education Center at the Coastal Maine Botanical Gardens Inspired By Nature 6 DPR Construction Phoenix Regional Office Phoenix Rising Some might say that the DPR Construction Phoenix Regional Office is a high performing building overachiever. It accomplishes goals of urban revitalization, adaptive reuse and net zero energy in a desert climate. When conditions permit, a passive cooling and ventilation system draws air in through operable windows and "shower towers," exhausting it via a passively heated solar chimney. Occupants also contribute to the buildings' low annual energy use intensity of 26.8 kBtu/ft2 by accepting a wider temperature range and making other adjustments. Operational savings from the building's sustainable design are expected to result in an eightyear payback. 4 HIGH Visitors come to the Maine Coastal Botanical Gardens' Bosarge Family Education Center to improve their green thumbs, hear a concert or to celebrate a wedding. But, designers hope visitors will walk away realizing that net zero energy buildings are possible today even in cold climates. A super efficient envelope includes 1 ft thick walls and triple-glazed windows, which keep out the cold while providing views of the surrounding gardens.

Elementary, the nation's first net zero energy school? Hint: It would involve a lot more than changing out the lightbulbs. The hypothetical redesign of Richardsville, which opened in 2010, eliminates parts of the original daylighting design and involves architectural changes. The revised design also replaces the somewhat problematic lighting dimming control system with manual controls. The result: a building that would maintain net zero energy status and cost $90,000 less to build. PERFORMING BUILDINGS 30 LED Lighting Spring 2014
