Built

Different

Boston Medical Center’s Brockton Behavioral Health Center is more than a renovation project—it’s a national first. By transforming a 1970s-era nursing home into a state-of-the-art, Zero Energy Ready / Zero Carbon Ready behavioral health facility, CMTA helped redefine what healthcare infrastructure can be: energy-efficient, resilient, and patient-centered.

Our Success

Through adaptive reuse, CMTA transformed a 1970s nursing home into a resilient, all-electric facility centered around patient care.

Built Different

"From outdated nursing home to zero-energy healthcare."

Adaptive Reuse Challenge

Converted a 1970s-built former nursing home—originally operating at an EUI of 95 kBtu/ft²/yr with inefficient masonry walls and natural gas steam heating—into a leading-edge behavioral health facility.

Low Ceiling Heights, High Complexity

Engineered flexible HVAC systems within tight floor-to-ceiling constraints, overcoming the absence of centralized AC, ductwork, and ventilation.

Optimized Envelope

Delivered a new R40 roof, triple-pane glazing, and an R19 composite wall system with continuous insulation—dramatically reducing heat transfer and air infiltration.

Electrification at Scale

Designed and installed an 88-well geothermal HVAC system to provide efficient, all-electric heating and cooling for the 80-bed inpatient treatment center.

Solar Integration

Coupled the geothermal system with a 700 kW PV array across the roof and parking canopy to offset 100% of annual energy consumption. PV is expected to be completed in 2025 and the NZE verification process will begin.

Built Better

“Engineering zero energy. Delivering better outcomes.”

Building Performance Milestone

Achieved the first operational zero-energy-ready / zero-carbon-ready behavioral health center in the U.S., setting a new national precedent.

Envelope + Systems Synergy

Integrated high-performance walls, roof, and windows with advanced geothermal and solar systems to maximize efficiency.

Continuous Operations

Designed to maintain patient care without interruption, even in extreme weather or grid disruptions.

Better Spaces for Healing

Created a patient-centered environment that combines energy efficiency with healthy indoor air quality, lighting, and comfort—directly supporting recovery.

Built for What's Next

“Healthcare that prioritizes people and the planet”

Resiliency First

Fully electrified systems prepare the facility for grid challenges while ensuring critical healthcare uptime.

Scalable Template

Provides a repeatable model for healthcare campuses nationwide seeking to decarbonize without compromising performance.

Aligned with Climate Goals

Supports state and federal targets for zero energy ready / zero carbon ready buildings while reducing operational costs for the long-term.

Future-Proof Infrastructure

Positions Boston Medical Center as a leader in sustainable healthcare, integrating flexibility for future technologies and system upgrades.
