Designers sought to connect building users and visitors to the pre-agricultural history of the site by restoring forest and wetland ecosystems. Images of the wetlands from 2001 and 2007 illustrate the rapidly developing natural landscape around the Lewis Center.

electricity occur at opposite times of the year (Figure 2). Although electricity production and consumption are nearly balanced on an annual basis, the facility functions as a net importer during the winter season
(and at night) and a net exporter during the summer season (and during sunny periods of the day). In northeast Ohio, peak rates of grid electricity consumption (as well as peak wholesale prices for
electricity) occur in the summer months and coincide with peak export from the Lewis Center. Therefore, although the Center represents a small source of power, the seasonal patterns of photovoltaic

Average gross electricity consumption for each month is depicted as a stacked bar graph of mechanical equipment associated with the Living Machine, lights, plug loads and HVAC. Average electricity production is illustrated as a stacked bar graph of the rooftop PV array and the parking lot PV array (data period for the parking lot array is June 2006–September 2010). Error bars for each month are the standard deviation of interannual variability in total site energy consumption and total photovoltaic production. The inset on the right shows annual averages in production, consumption and net use.
