The School Sisters of Notre Dame (SSND) are members of an international congregation of religious women with campuses in 31 countries. Acting on their commitment to environmental stewardship, SSND completed a comprehensive energy efficiency project on their 38-acre campus in Wilton, Connecticut.
The complex includes 200 dormitory-style rooms, a commercial kitchen, a 40- bed licensed nursing facility, a Montessori School, a chapel, offices, and three additional residences.
MHR facilitated this retrofit, providing project development, technical and implementation services. The scope included envelope improvements, high-efficiency LED lighting, modulating steam boilers, water conservation measures, heat destratification, and two planned solar installations. For these energy efficiency upgrades, MHR secured received $141,240 in utility incentives.
In addition to a comprehensive energy efficiency upgrade, MHR managed the installation of two solar systems. The Solar Garden, Wilton’s first ground-mounted system, will provide 122 kW of power. The second system will be a 37 kW system mounted on the roof of Lourde’s Health Care Center. Cumulatively the systems are expected to generate 200,000 kWhs annually.
PRINTABLE CASE STUDIES
The properties at the School Sisters of Notre Dame in Wilton were in desperate need of sustainability upgrades. Mark Robbins and his team at MHR Development were with us through every step. From water conservation, LED lighting upgrades, energy efficient boiler plant to solar, we could not have done this scope of a project without MHR.
