"This building surpasses expectations and dreams, not only becauseof the sustainability and Platinum design, but also the potential forprogramming and sharing the wonders of nature with generations to come at HiddenOaks is limitless." Programming at Hidden Oaks will provide creative interpretive learningexperiences which awaken a sense of wonder and encourage responsibleenvironmental behavior. Taking its cue from the wooded site, the new 7,000 square-foot building sitsbetween two large oak trees to create a "tree house" feeling. Decks around theoak trees give visitors a chance to be immersed in the restored woodlandecosystem. "When I first saw the project site, I immediately recognized one of the mostendangered ecosystems of the Midwest-an oak/hickory woodland," said Jay Womack,ASLA, LEED AP, Wight`s director of sustainable design.

"The restoration of thenative flora that once flourished below these massive oak trees, some of whichmeasure sixty feet across, will bring back an Illinois ecosystem that mostpeople have never seen before. When visitors stand within the woodlands, theywill truly be standing in Illinois." Housed within the center will be two early-education classrooms specificallydesigned for Seedlings Preschool, two multi-use rooms, staff offices, andinterpretive displays. Sustainably designed and built, it has been registeredwith the US Green Building Council to meet Leadership in Energy andEnvironmental Design (LEED-NC) Platinum standards. The building incorporated site-harvested timber; recycled and locally availablematerials; light shelves for daylight harvesting; low flush toilet fixtures andurinals; and solar-powered faucets that use motion sensors to turn the faucet onand off. Sunshades have been strategically placed to minimize glare and solarheat gain. Paints and varnishes which contain low VOC levels, and wood productsthat do not contain added urea-formaldehyde heighten the quality of indoor air.Regarding electricity, Photovoltaic panels, connected in parallel to theelectrical service, supply the building with energy while excess output returnsback to the grid.

In addition, occupancy sensors shut off interior lights whenstaff or visitors are not present. The list of sustainable features continues outside the building: integratedphotocell and time clock devices control site lighting. The green roof featuresnative plants that do not require irrigation. Permeable pavers in the entrydrive will reduce stormwater run-off while also reducing urban heat islandeffect. A geothermal system will provide an efficient way to heat the buildingduring winter and cool it during summer, while Energy Recovery Ventilatorsreduce energy by reusing pre-conditioned air.
