Choate Rosemary Hall

Kohler Environmental Center


Choate Rosemary Hall embarked on a plan to create an innovative environmental center on over 260 acres of property adjacent to its existing campus. Made possible by a generous gift of Herbert V. Kohler, Jr. (class of 1957) president and chairman of Kohler Company, the new center combines interdisciplinary academics with a residential program focused on environmental science. Designs incorporate 14 dormitories, dining facilities, seminar rooms, laboratories, faculty/staff housing, and a state-of-the-art greenhouse.

Kohler Ronan is delighted to have designed the sophisticated MEP/FP systems for this unique facility. Sustainable elements were integral to the project since project goals included LEED Platinum certification and net-zero energy usage. To help achieve these goals, Kohler Ronan conducted energy simulations using advanced modeling software. We were able to determine the building’s best performance based on variables like orientation, window & door placement, insulation, equipment, daylighting, and natural ventilation.

One hundred percent of energy needs are provided by a 296 kW photovoltaic array, roof-mounted evacuated solar tubes, and waste oil. Earth ducts were found to reduce heating-related energy use and costs significantly. Today, students are able to track building performance via specialized dashboard monitoring systems.
