Who We Are

We are a consulting firm that is passionate about making Canada’s built environment more energy efficient. To do this, we provide planning, energy use quantification, and site support for clients interested in meeting energy efficiency targets. Located in Nelson, British Columbia, we service the Kootenays of interior BC and beyond.

We know that with a little coordination, an energy efficient building has the potential to be healthier and more comfortable than standard construction. That’s why we work with a holistic perspective of the indoor environment. We can support the design to improve indoor air quality and thermal comfort. We can offer building air-tightness mentoring, assess the building envelope’s moisture risk and durability, and size heating and cooling equipment to minimize capital costs.
