Clanton & Associates designed the exterior lighting for Vermont Southern State Correctional Facility in Springfield, Vermont.
This project was unique because the State of Vermont was building a new state correctional facility, within 6.5 miles of the historic Stellafane Observatory. Both entities initially had separate goals, but developed an agreement whereas the dark skies above Stellafane were preserved, yet the correctional facility had quality security lighting.
A unique design was constructed where only the building facades and interior surface of the perimeter fence were lighted all with fully shielded downlights. Visibility for security guards is excellent, giving them the benefit of detecting movement via silhouette against the lighted facades. This type of security lighting had never been performed successfully until this project.
Since any additional lighting increases sky glow, the State of Vermont signed an agreement with the Springfield Telescope Makers, Inc. guaranteeing no increase in sky glow, through the mitigation of light pollution from three private sites selected by Stellafane. Clanton & Associates performed the mitigation report which reduced the sky glow above Stellaphane to below pre-correctional facility construction.
As stated in an article by the International Dark Sky Association: "Construction of this 350 bed facility was controversial, but for an unconventional reason: A person's 24 hour high intensity security lighting could cause massive light pollution, with harmful effects on the dark skies of nearby Stellafane Observatory, a National Historic Site and host of the annual Stallafane Convention, whose visitors provide a major economic boost to the town of Springfield. Faced with petitions signed by Stellafane supporters from across the world, Vermont governor Howard Dean agreed to a compromise, and had the prison lighting designed by experts recommended by the International Dark Sky Association. Springfield prison is now a model for low impact (and energy efficient!) outdoor lighting."
