About Us
Sustainability is rapidly evolving.
So are we.
Sustainability is the future of our built environment but often it can be made to be over-complicated, expensive, and onerous to integrate into projects of all scales. Our dedicated professionals focus on ensuring that we are fully integrated with your team - reducing project complexity and stress while obtaining the best possible option.
Drawing on nearly 40 years of combined experience leading projects in the healthcare, transit, commercial, industrial, institutional, and residential sectors we guide our clients to achieve their goals through unparalleled service, project leadership, and hands-on attention to detail. Our approach is one that focuses on customization for each client and each project, no matter the size.
We see ourselves as your partner, heavily invested in exploring all possibilities from conventional practices to completely outside-the-box thinking. Our passion is our drive, and we think our service delivery is one that you will find refreshing.
In August 2021, Quasar Consulting Group and Pratus Group announced a partnership combining Quasar’s consulting with Pratus’ sustainability and energy management consulting.
The goal remains the same; to drive high-performance building design that meets the needs of clients while simultaneously reducing the impacts of climate change.
