About Us

Pratus Group is Quasar Consulting Group’s specialized brand dedicated to sustainability, building performance, and commissioning services. In August 2021, Quasar Consulting Group and Pratus Group announced a partnership combining Quasar’s consulting with Pratus’ sustainability and energy management consulting. Quasar’s consulting engineering expertise is closely coupled and complementary to Pratus’ focus on sustainability, energy management, and commissioning, with the shared objective of creating high-performance building designs that not only meet clients’ needs but also significantly mitigate the impacts of climate change.

Onwards and Upwards.

Our Mission

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.

Client-Focused. Future-Ready. Climate-Responsive.

Sustainability is evolving - so are we

At Pratus, we believe sustainability shouldn’t be complicated, costly, or overwhelming. Our mission is to simplify the path to high-performance, sustainable design by working as a true extension of your team, minimizing complexity while delivering smart, practical solutions tailored to your project goals.

Whether through proven strategies or bold, out-of-the-box thinking, we’re committed to exploring every possibility to help you succeed. Our passion fuels our process, and we think you'll find our service approach refreshingly different.

Sustainability. Simplified.
