Decarbonizing and electrification of buildings with carbon-free heat pumps

Belinda Gilbey is a woman entrepreneur, green building enthusiast and market leader in heat pump technology. Her graduation from the University of Ottawa with a Bachelor’s degree in mechanical engineering kick started her successful professional journey that was fueled by her passion for clean technologies. For several years, she worked in sales and consulting helping commercial property owners, operators, and developers with their mechanical equipment needs, with a focus on improving efficiencies and reducing building energy consumption and operating expenses. While working in the solar and heating, ventilation, and air conditioning (HVAC) industries, she gradually developed a true passion for creating cost-effective decarbonization solutions for a better tomorrow, which brought her to co-found and become President of Bondi Energy. Since then, she’s been raising awareness on the positive effects that these technologies provide, not only from an environmental point of view but also from a cost reduction angle. Under Belinda’s guidance, Bondi is now aiming to decarbonize as many buildings as possible across North America. Belinda is co-founder of US-based Gigawatt Heat Pump Supply (2021), which sells efficient heat pump and electrification equipment for new-build and retrofit applications.

Shortly after its inauguration in 2019, Bondi became a market leader in energy efficiency retrofits of multifamily and commercial buildings. Aaron, along with his partner Belinda, have accelerated the market uptake of heat pump technology across North America. Aaron’s background in commercial real estate gives him a unique understanding of how energy affects building values and their owner’s decision-making process.

Every Home Has A Story To Tell

David Tiefenbach, Owner, Atta-Boy Property Inspections, grew up in a small town just east of Regina and spent a lot of time at his grandparents’ grain farm. It was an integral part of his life at a young age. After high school he went into the plumbing and gas fitting trade, moved to Edmonton 2005 and started his plumbing business in 2006. In 2017 he was excited to get into the cannabis business but “ended up losing my shirt.” In 2018 he got his home inspector licenses and started Atta Boy Property Inspections early 2019. His intent was always to sell Atta-Boy franchises and help others in the trades to find something different and easier on the body.

“I have a strong belief and I have the determination to make this successful for trades people and any other with a good work ethic who are interested. I know my support system on the business side is what really matters for the franchisees to become and stay successful. This isn’t about home inspections this is about learning the business about home inspections. This is about building relationships for success. That’s why I call it Inspection Success,” he says.

In February 2023, Atta-Boy will start taking applications from any teenagers from 15 to 19 who may think they might be interested in Home Inspecting and seeing other trades in action from framers, electricians, plumbers, HVAC guys and insulators. He has set up a summer school holiday program from July 1 to Aug 31 for teenagers to have an opportunity to shadow these trades in action and to spend the last remaining 2 weeks with him shadowing him doing home inspections. It’s all free and the intent is to spike interest and possibly look at a trade school and possibly maybe a future Atta-Boy franchisee owner after learning their trade of choice.

Tiefenbach also has a goal to build an acreage just east of Sherwood Park with a picture in his head of a couple of Clydesdales roaming around.
