Safety, Comfort, and Efficiency

Our Approach

We combine technical expertise with the intangible human elements of effective systems design and operation.

A significant component of user experience is how a person feels in a space, and mechanical systems can influence this perhaps more than any other behind-the-scenes building component. The best mechanical
systems are the ones users don’t notice—achieving this balance is a hallmark of excellent mechanical engineering.

We listen to stakeholder needs and ideas—from end-user occupants to operations and maintenance teams working every day to keep systems running smoothly to the architects designing the space. We focus on optimizing environments for comfort, air quality, humidity, temperature control, and ventilation to support the needs of various spaces and the overall occupant experience. We are problem solvers and just as comfortable troubleshooting challenges as we are crunching the numbers
to determine loads.

We prioritize communication and detailed documentation so clients understand the issues clearly and can make informed choices that achieve their goals and, ultimately, create inspiring and healthy user
