The Greening of Our Schools

As environmental conservation continues to take center stage in the global context, on a more intimate and local level, the concept of sustainability—the ability to continue to exist—has paramount implications when it comes to economics and energy savings.

When the referendum was passed to replace the 100-year-old building that housed the Post Road Elementary School in 2006, it is doubtful voters at the time realized the full impact of the decision they were making.

Today, the new 87,000 square-foot two-story structure has been referred to as the “greenest school in New York State” and a model for the rest of the country. Every effort was made during design and construction of the building to take maximum advantage of resources offered by the natural environment. The structure of the school and many of its design elements serve as teaching tools on ecology and energy conservation for students learning within its walls.

The doors opened on the first day of school in September and on November 7 a ribbon-cutting ceremony and tours were open to the public. White Plains Times attended a press tour of the facility before the school opened.

Eric Kaeyer, of Kaeyer Garment and Davidson, was the chief architect on the project. The entrance, on Sterling Avenue, leads to a circular courtyard, the central hub of the building, around which instructional space is located. The circular design allows for extensive use of sunlight that not only adds to the aesthetics, but also allows natural light into the corridors and workspaces. The library and art rooms are situated on the south side of the courtyard to receive softer light from the north, which enhances this type of work, according to Kaeyer.

Circular skylights are strategically located at corridor cross points to allow natural light into the hallways from all directions. Stairwells are built on the perimeter walls with large windows to allow natural light in as well. “In the old school there was no natural daylight in the corridors or stairwells, explained Kaeyer. The school’s 340-seat auditorium, 3,300 square-foot cafeteria, and 10,000 square-foot gymnasium, retained from the previous building, also have skylights to allow natural light into the spaces below.

By maximizing the use of daylight, costs for electricity are cut. Classrooms are fitted with light shelves at the windowsills to reflect light further into the room. Each row of interior lights features energy efficient florescent fixtures and has its own switch so teachers can light only those areas needing it. For example, on a sunny day, it might only be necessary to illuminate the interior aisle, keeping the rows near the windows “off.” Light fixtures are also fitted with a reflective shelf to bounce light off the ceiling. According to Kaeyer, not only does this enhance the effectiveness of the light fixtures it also cuts down on glare, creating a pleasant light balance for the students working below.

Solar panels provide hot water and depending on the time of year could produce as much as 100 percent of hot water used. The average over the course of a year is anticipated at somewhere around 50 to 70 percent. Photovoltaic solar panels to generate electricity were not chosen for the school because the pay back timeline for initial and operating expenses would take 25 years, says Kaeyer. Low flow plumbing fixtures are utilized to save water. Building materials from the floor carpets to the ceilings are all high-level recycled materials and selected for easy maintenance and durability. White boards, rather than black boards, have been installed in the classrooms for this reason.  Photo credit: Pat Casey
The flat roof surfaces have green roof plantings to reduce storm water runoff and to protect the roof from UV light, which is absorbed by the plants, keeping the building cooler. The plants are self-sustaining, add to the overall aesthetic of the building (the kindergarten classes look directly onto the green roof), and extend the life of the roof out to about 20 years.

As winter approaches, one of the more interesting “green” features of the new Post Road School—its geothermal convection heating and cooling system—will be put to the test. The school is not heated or cooled by conventional methods. There is no furnace, no boiler, and no air conditioners. Eighty-four wells dug to about 490 feet form a closed loop system using water for temperature exchange. The heat is literally pulled from the Earth.

According to Kaeyer, the economic pay back for the geothermal system will take from eight to ten years to be realized. Overall, the new Post Road School is expected to operate at 70 percent energy efficiency, using only 30 percent of traditional energy sources. “Overall building efficiency is up 40 percent compared to the letter of the code,” says Kaeyer. The original building will be deconstructed in the coming months and the space will be developed for playing fields and parking. More information about the architects who designed the Post Road School can be found by visiting kgdarchitects.com Green Schools Coalition of Westchester On Nov. 14, teams from 25 Westchester public school districts and private schools participated in the inaugural Green Schools Coalition of Westchester Membership Conference. The event, held at the Reckson Metro Center in White Plains, included content developed from feedback from over 60 educational institutions in Westchester that responded to a questionnaire regarding school sustainability issues. The goal was to provide a venue for collaborative efforts and resource sharing for schools within the county to have a support mechanism for their sustainability plans. Coalition co-sponsors include, The Children’s Environmental Literacy Foundation (CELF), Teatown Lake Reservation, and Westchester County.

Conference keynote speaker, Dr. David Hursh, Associate Professor of Education at the Warner School of Education at the University of Rochester, shared his background and experience in sustainability education with the group, including ideas from his upcoming book, “We All Live Downstream: Interdisciplinary Learning Through Environmental Health Science.”

Attendees were organized into teams composed of a student, teacher, administrator, facilities manager, and parent. The teams first heard from speakers, then worked together in breakout sessions. The information and ideas shared are expected to be brought back to their schools and districts for distribution to their larger school communities for the creation of action plans. Superintendents and headmasters may register “teams” to become members of the Coalition. In order to join, schools must pledge support for the ideals of sustainability education and recognition of its importance. GSCW members are expected to attend conference and meetings and agree to collaborate with other Westchester school teams to support their shared vision. Steve Frantz, GSCW Director and Scarsdale Schools Sustainability Coordinator, announced that GSCW will be a co-sponsor of the CELF 2010 “Students for a Sustainable Future EXPO,” hosted annually at Pace University in Pleasantville. The Expo will be held April 20, 2010 from 6 to 9 p.m. Registration for Expo exhibitors and visitors opens Dec. 15 online at celfeducation.org.
