Opened in 2003, the Kimberlin Nature Education Center is the heart of our Audubon Center in Greenwich. Built with environmentally friendly materials and techniques, it is the main welcome center and an active hub for conservation events, exhibits, classrooms, and the Audubon Greenwich & Audubon Connecticut staff offices.
Also inside is the Hilfiger Children’s Learning Center—an indoor, hands-on area with nature-themed activities, natural history exhibits, puppet theater, story corner, and a wildlife observation window. This play space is not only ideal for families with younger children, but is also enjoyed by visitors of all ages for its views and exhibits.
Other attractions include: 'Audubon At Home' themed exhibits about eco-friendly gardening practices and a well-stocked Nature Store & Gift Shop with a wide selection of toys, guide books, binoculars, bird feeders, seed, and snacks for hungry hikers.
The Kimberlin Nature Education Center is also available for special event rentals and children's birthday parties and serves as a starting location for the many guided hikes and public events throughout the year.
The Kimberlin Nature Education Center's “green” design features include:
- Recycled fiberglass window frames
- Recycled plastic to construct outdoor decks
- Beams made of recycled steel
- Recycled gypsum wallboard
- Insulation made from recycled paper
- 100% wool carpeting
- Flooring, shingles, and other lumber certified to be from sources utilizing conservation forestry practices
- Cement and asphalt paving replaced with gravel or crushed stone, allowing rainwater to infiltrate and recharge groundwater
- Geothermal HVAC system
The biggest payoff is the geothermal heating and cooling system. Conventional systems heat air with electricity or by burning natural gas when outside air is coldest. Conventional summer systems cool air when it is hottest, using electrical refrigeration. These methods of cooling and heating are expensive and contribute to global warming.
At Audubon Greenwich, the earth heats itself and cools the building, taking advantage of the constant year round temperature (about 54 degrees) of the ground 4 feet or more beneath the surface. A liquid—chemically similar to antifreeze—is pumped underground into a grouping of pipes (made from recycled plastic). Liquid colder than 54 degrees is warmed, and liquid hotter than 54 degrees is cooled, both by the surrounding earth. The heated or cooled liquid (depending on the season) passes through the closed loop into the building, which it heats or cools as needed. That precise need is determined by computer-operated controls.
The energy for changing the temperature comes from the sun-warmed earth, and it is free. The only added energy is electricity to circulate the liquid and run the heat pump.
