Design turnkey decarbonization projects for industrial, commercial and multi-family homes. Krome takes care of everything from diagnosis to finding subsidies, including the work, with a guarantee of the costs and the savings achieved.

Who ?

Sandrine Tremblay was born in Saguenay, where her father, an entrepreneur and mechanical engineer, allowed her to go to construction sites from an early age. “I saw myself as an engineer at the age of 5 on the construction sites where my father took me; The future has proven me right,” she says on her LinkedIn page.

She followed in her father’s footsteps and graduated in 2003 with a bachelor’s degree in mechanical engineering. After that she worked for different companies, in particular for the American company Ecosystem Énergie Services for 11 years, where she implemented several energy efficiency projects. “I saw a market for medium-sized industrial, commercial and multi-family homes, but there was no expertise,” she says. It’s a good niche when no one is in a market. »

In 2016 she founded Krome in Montreal. The company currently employs around twenty people and oversees an average of eight projects per year.

The product

Krome’s specialty is retrofitting the central heating, air conditioning and ventilation systems of medium-sized buildings to reduce energy costs, recover and properly redistribute heat, while reusing as much as possible of the materials already installed. For example, you can switch from natural gas heating to electricity and install heat pumps. Krome does not interfere with the insulation and does not redesign the buildings. All work is carried out by subcontractors, “installers, electricians, ventilation specialists, control companies”: “In the environment in which I work, they know their customers, their market”, explains Tremble. As a conductor, I come into an already established ecosystem. »

Krome also lays out the ultimate cost of the project, with government grants averaging 45%, and promises energy savings of around 30%, sometimes more. The small company boasts that it has avoided 35,000 tons of greenhouse gas emissions and achieved savings of almost 3 million for its customers.

It really is turnkey. I guarantee the costs, the contractors, the subsidies, the funding. In the end, if the customer doesn’t have operational losses, it’s up to me to reimburse them.

If it is desirable to construct new green buildings, reducing greenhouse gas emissions must be done by redesigning older buildings, she explains. “Sustainable development also means restoring existing infrastructure and making it consume less with highly innovative projects and technologies. »


Finding workers in this sector, workers, engineers and other sought-after professionals, is a constant challenge. “It’s a growing segment,” says Tremble.

The other challenge affects virtually every industry: dealing with strained supply chains. “If we don’t have the machines to build our projects, we can’t do them. There are many needs. »

The future

Rather than focusing on one project at a time, we would like to be able to propose more ambitious plans to large building owners who could, for example, set a target for 2030. The exercise would also have the advantage of greater predictability, which makes it possible to address the various bottlenecks in the industry overcome.

Rare precision for a young growing SME, we are not yet targeting the market in the United States let alone anywhere else in the world. ” There is work in Canada, notes the CEO. We are good at what we do, we want to do more. »

One of the developments Krome’s founder sees is that financial institutions are becoming increasingly demanding when it comes to decarbonization. “It is an extremely profitable investment to decarbonize a building. The carrot didn’t work enough, but if the banker doesn’t want to roll over your mortgage, then you feel like making a plan. »
