"In terms of size and complexity, this was not a typical AEI project. In terms of impact, the early integration of repeatable engineered efficiencies is accessible, affordable, and universally applicable."
Combining an effective, intelligent design approach with practical applications of established sustainable technologies, the Village of Plain Green Technology Training and Enterprise Center (G-TTEC) achieved a perfect energy and renewable energy credit score for LEED Gold certification. AEI’s holistic system design of basic, energy-saving features for the 11,000 sf facility was so fully integrated with the preliminary architectural composition that the building design remained virtually unchanged through construction. Energy loads were significantly reduced through optimal building massing, operable windows, a high performance envelope, high-efficiency lighting, and active daylighting. As a result, radiant heating and cooling and a 14-well geoexchange field became feasible to further reduce energy consumption. Other energy-efficient features include: a dedicated outdoor air system for ventilation and humidity control with a total energy wheel; a condensing boiler; low-flow plumbing fixtures; and, a 20+ kW photovoltaic system. Dedicated to training local workers in green technologies, the G-TTEC serves as a practical demonstration of sustainable design for the commercial and residential industries. The facility is anticipated to reduce overall energy usage by an estimated 74 percent versus an ASHRAE 90.1-2007 baseline.
From the client:
"Natural ventilation might not work everywhere, but it definitely works in Plain, Wisconsin. It was 95 degrees in July (2011), and the crews working outside had to stop at ten in the morning, but it was significantly cooler in the building because of the passive design, allowing the crews inside to work full days in the extreme heat and humidity. The natural ventilation provided a great breeze. It saved the schedule, really. Due to the long lead-time of our windows we had to start the drywall work before the building was 100% enclosed. We thought the high humidity would extend the taping and finishing process of the drywall, but the natural ventilation kept a nice breeze going through and kept everything on schedule."
