Operable windows throughout the building provide free conditioning, resulting in minimal use of air conditioning. 2002 2004 2006 2008 2010 buiLding enveLoPe Roof Curved portion (70%): Type laminated beams, standing seam aluminum -value 27 r flat portion (30%) r-value 20.5–40.5 overall r-value 27 reflectivity High Walls Type Brick r-value north earth-bermed wall r-12 Auditorium wall r-20 All other brick walls r-19 glazing percentage 43% Foundation Perimeter footings r-21.6 slab floor in atrium r-11.5 first-floor classroom floors r-12 Windows u-value 0.14 on triple pane atrium windows, 0.3 on double panes used in classrooms and offices Location latitude 41.29 orientation elongated on east-west axis; roof and atrium face due south The changing ratio of soil temperature at 5 in. depth to air temperature during the month of July at four locations in the landscape reflects shading provided by maturing vegetation and the increase in soil surface organic matter, which acts as insulation. Although the scale of the technology may be more applicable to a small community than to a single building, the Living Machine has helped challenge people’s perceptions of waste versus resource. The remarkably clean smelling air within the greenhouse, the lush green tropical foliage emerging from the tanks and the periodic profusion of blooms create a stark and welcome contrast to the coldest and darkest days of the Ohio winter. Connecting People and Place The goal of creating a building and landscape that teach lessons about humans’ relationship with the environment has been realized at the Lewis Center in several ways. One approach has been to develop a system for displaying the environmental performance of the building in real time. Over the course of the last 10 years, an increasingly sophisticated website and public lobby display have provided building visitors, occupants and the larger community with a view into the energy flows, cycles of matter and environmental resources necessary to support activities in the built environment. The premise of this work is that real-time performance data can be used to engage, educate, motivate and empower conservation of resources and appreciation of renewable energy. At least as important as computerbased displays are the direct sensory and emotional experiences that people have within buildings and built landscapes, which teach Winter 2011 H i g H P e r f o r m i n g B u i l d i n g s 33
