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 kWh annually.
