About Us

We are a building energy technology and financing company that resolves the persistent barriers to meaningful energy and environmental performance in buildings


We believe that buildings are the game-changers in the fight against climate change – they offer the greatest opportunity to reduce carbon emissions for least cost.


We each have decades of experience in our respective fields.  Collectively, we:

  • Have analyzed and managed energy flows in hundreds of buildings
  • Are familiar the latest energy saving technologies and solutions
  • Have a deep understanding of the construction industry
  • Understand real estate and construction finance; and
  • Are experts in sustainability and local government requirements

In short, we have the knowledge and desire to create profitable and long lasting partnerships that will transform that way we generate, sell, and use energy.

Nick Farina

Director, Business Development


Nick Farina thrives at the leading edge of the rapidly evolving building energy technology space. With over 40 years in the field, he brings to eStresm his deep industry knowledge combined with a fascination for innovation and a strong entrepreneurial instinct. Prior to eStream, Nick was the President and Chief Operating Officer of Enerpro, which he founded in 1996 as a full service provider of intelligent, energy management programs for new construction and infrastructure upgrades in retrofitted buildings.

During his tenure with Enerpro, Nick pushed the envelope with existing buildings and new construction, directing the design of control and measurement systems in over 100 buildings. This work resulted in saving businesses and strata councils millions of dollars by delivering substantial energy savings (many by more than 50%). A highlight was Nick’s leadership in introducing measurement and optimization technology to the award-winning Vancouver Olympic Village, helping the project become the first LEED Platinum neighbourhood in Canada.

Despite so many technical accomplishments, Nick understands that the barriers to energy management and the reduction of consumption are not simply technical — in fact, they are mostly human and economic. His role at eStream encompasses both business leadership and working hand-in-hand with building owners and developers to eliminate the financial hurdles to energy efficiency within the constraints of a competitive construction market.
