At Ecosystem, we believe in building meaningful relationships with both our clients and employees. With curiosity and collaboration, we do breakthrough work so our clients achieve environmental, financial, and operational results and reach their ambitious decarbonization goals.

When we sit around the table with our clients, solving problems in their buildings, we work together to align our interests and identify the outcomes important to them. From the outset, we believe that accountability for achieving the outcomes that matter to our clients should completely lie with us. After all, we are engineers with three decades of experience in energy retrofits, and our proven expertise and track record of innovation is why we are invited to the table in the first place. 

To be accountable, we've built a business that re-connects engineering design, construction and commissioning with a total focus on delivering results. This way, we can contractually guarantee the outcomes that mean the most to our clients while acting as a single point of contact throughout each step of the journey. With over 200 specialists and offices in Quebec, Montreal, Toronto, New York City, Boston, Los Angeles, and Columbus, we are the go-to engineering and construction firm for energy projects across multiple industry sectors.
