Case Study

Trinity Health New England

Trinity Health New England - LED Lighting, HVAC/Mechanical, Building Management Systems

Trinity Health of New England contracted with the efficiency solutions group at Mantis Innovation to develop and implement lighting and mechanical efficiency solutions at three of its hospitals:

Saint Francis Hospital – Hartford, CT
Mount Sinai Hospital – Hartford, CT
Johnson Memorial Medical Center – Stafford Springs, CT

The total cost of the efficiency solutions was approximately $6 million with annual electricity savings of over 8 million kWh and gas and oil savings of over 260,000 therms.

We accessed the Connecticut Energy Efficiency Fund through Eversource and CNG for over $3,250,000 of incentives, resulting in a project that pays for itself in just 2 years.
