Mechanical Engineering
Engineering Healthier Environments
In healthcare, the mechanical environment is part of the care environment.
Temperature, humidity, airflow, pressure relationships, filtration, ventilation, noise, and system reliability can influence patient safety, comfort, and recovery, infection prevention, clinical workflows, staff performance, energy use, and the ability to respond when conditions change.
For more than 60 years, Mazzetti has designed mechanical systems for hospitals, healthcare campuses, laboratories, and other complex facilities across the country and internationally. Our engineers understand both the science of building performance and the operational realities of the people who maintain and depend on it.
Our Projects
60+ years of experience – Hundreds of healthcare clients – National and international reach
Designed Around Care Delivery
Mechanical systems that respond to how healthcare actually works.
Healthcare mechanical engineering requires understanding how care is delivered and how the building must respond. We work closely with clinicians, infection preventionists, facility teams, architects, contractors, and owners to balance clinical requirements, resilience, maintainability, energy performance, flexibility, first cost, and long-term operating cost.
Built for Every Healthcare Environment
Our teams support highly controlled clinical spaces, complex infrastructure, and renovations within continuously operating facilities.
- Operating and procedure rooms
- Patient rooms and critical care units
- Isolation and protective environments
- Emergency and trauma departments
- Sterile processing and high-level disinfection
- Imaging and radiation treatment
- Pharmacies, laboratories, and specialty care, including Behavioral Health
- Central utility plants and campus distribution systems
- Renovations within continuously operating facilities
Our designs balance clinical requirements, resilience, maintainability, energy performance, flexibility, first cost, and long-term operating cost.
Advancing Healthcare Ventilation
Our professionals are active in the committees, research, and industry collaborations that shape them, including work associated with ASHRAE Standard 170, ASHRAE Standard 90.1, the Facility Guidelines Institute, and guidance addressing infectious aerosols.
We’ve spearheaded industry progress by advancing displacement ventilation in healthcare settings. Our research examining energy consumption and heat gain from medical equipment has informed “right-sizing” HVAC loads in associated clinical spaces and integration into the layout with the architect.

Performance That Endures
Through our collaborative process with the end users taking their input into account, we design mechanical infrastructure to perform not only on opening day, but throughout decades of changing care models, equipment, climate conditions, regulations, and operational demands.
The result is a healthier, more resilient environment for patients, caregivers, communities, and the planet—and another opportunity to bend the climate curve™.
