This project underscores NERVA's credo of "Unlocking Your Building's Full Potential, "backed by their GUARANTEED ENERGY PERFORMANCE SOLUTIONS.

"In the ever-evolving landscape of building optimization, owners often find themselves navigating the intricate maze of multiple subject matter experts. This fragmented approach often leads to unnecessary conflicts, adding layers of complexity that can be overwhelming. One of the major challenges in this industry is the noticeable gap in performance certainty and accountability. It's this very lack of clarity that erodes client confidence, sometimes halting action entirely.

At NERVA, we've always believed in streamlining this process, implementing practical and measurable solutions that offer clarity and, above all, results. Our mission is to restore that lost confidence and to be the beacon of reliability in an otherwise convoluted industry. " Says Rob Hallewick, CEO, NERVA Energy Group.


In Ontario, large buildings rank as the second-highest source of green house gas emissions and significantly strain our electrical grid. With the challenges of regulatory mandates, rising utility rates, and the Federal Carbon Tax, building owners are under increasing pressure to act. However, the scarcity of practical and established solutions has become a major obstacle for the industry, complicating efforts to manage operating expenses and capital investments.

"After years in the industry, we've come to understand the intricate nature of mechanical systems and the pressing need for specialized expertise. Without the right partner, a lack of internal resources and expertise can lead to a fragmented strategy and ultimately,  disappointing results. Partnering with NERVA Energy transformed this narrative for us.


Their turn-key project delivery model meant that we could concentrate our energies on defining clear goals and expectations. In turn, NERVA took the reins, implementing tailored solutions that catered to the unique needs of each building. The outcome? Not only did they meet our expectations, but in many instances, they exceeded them. It underscores the immense value of having a trusted partner like NERVA when charting the course for energy conservation solutions. " says Allan Drewlo, CEO, Drewlo Holdings

In an industry where building owner soften grapple with maximizing their investments, the journey towards meeting our nation's carbon reduction  goals is illuminated by visionary leaders like Drewlo Holdings. Partnered with the seasoned expertise of NERVA Energy, they pave the way in decoding the challenge, championing practical solutions that promise measurable and guaranteed outcomes.
