Transform your mechanical systems, energy sources and operating costs, with guaranteed results
From mechanical optimization, to the renewable energies integration, we handle the design and implementation of your projects for commercial, institutional and industrial buildings in Quebec.

Concrete actions to correct sources of energy inefficiency
Many buildings experience declining performance due to aging equipment, poorly controlled systems or too energy-intensive technologies. Costs increase, comfort deteriorates and projects are delayed due to the lack of a partner capable of managing them from A to Z.
We carry out energy efficiency projects to modernize your facilities, reduce losses and support your decarbonization objectives with well-executed projects designed to generate lasting gains.

Integrated implementation capability, from start to finish, of the project
Our Construction offering covers all the work necessary to transform an energy improvement opportunity into concrete results: mechanical systems, energy distribution networks, lighting, heat recovery, aerothermal and geothermal systems.
A key differentiator: we hold an RBQ electrician contractor’s license and have an in-house teams. It allows us to better control execution quality, site coordination and final performance on lighting, control, power supply and electrical optimization projects.
Our expertise in energy efficiency implementation and modernization
Mechanical system optimization and modernization
We improve the performance and reliability of your HVAC and hydronic systems and production equipment by targeting energy losses, control inefficiencies and obsolete equipment. The objective: reduce your operating costs, improve comfort and prepare your facilities to integrate more efficient technologies.
Optimization of energy distribution networks
We work on your steam, hot water, chilled water, compressed air and other fluid networks to reduce losses, improve balancing and modernize critical equipment. By optimizing distribution, you improve operational stability, reduce energy consumption and maximize the overall efficiency of your facilities.
Integration of renewable energy
We support the integration of solutions such as: solar, biomass, geothermal energy and recovered heat, based on your site’s energy profile and objectives. Our approach allows us to design tailored solutions that reduce GHG emissions, improve your energy autonomy and stabilize your long-term costs.
Air-source heat pumps and geothermal systems
We design and implement heating and cooling systems based on heat pumps and energy captured from the air or the ground. These solutions can significantly reduce your energy costs, improve your buildings’ performance and support a sustainable decarbonization pathway.
Heat recovery
We identify sources of wasted heat in your processes or buildings and design solutions to efficiently recover it. By recovering this free energy, you reduce your heating needs, improve your energy performance and often achieve an attractive return on investment.
Lighting modernization
We carry out LED conversion and lighting optimization projects with a turnkey approach: analysis, design, photometric studies, installation and control. Thanks to our in-house electrical expertise and our RBQ license, we deliver high-performance projects that reduce consumption, lower maintenance costs and improve the quality of illuminated environments.
Our implementation approach
Each project is designed to deliver measurable results while fitting into your site’s operational reality.
01
Understand and define the scope
We analyze your needs, technical constraints, operating conditions and your financial objectives to define the project scope and priorities.
02
Design and plan
We design a solution tailored to your reality, prioritizing feasibility, performance and long-term savings, then we plan the work to minimize the impacts on your operations.
03
Execute and coordinate the work
We manage all the work and coordinate all the stakeholders through a single point of contact, ensuring execution quality at every stage of the project.
04
Commission and monitor
We provide full system commissioning, validate the generated savings and monitor performance to confirm the results.
A distinctive advantage: our in-house electrical capability
Our in-house electrical team and electrical contractor’s licence allow us to better control the quality execution on lighting, power supply, controls and facility optimization projects.

Q&A
What types of energy efficiency work do you carry out in buildings across Canada?
We carry out energy efficiency work related to mechanical systems, energy distribution networks, lighting, heat recovery and the integration of renewable solutions such as air-source heat pumps and geothermal systems. Our interventions are adapted to commercial, institutional and industrial buildings.
Do you carry out the work in-house or with subcontractors?
We have an integrated delivery capability, including in-house expertise in electrical projects with an electrical contractor’s licence and dedicated teams. It allows us to better control execution, coordination and quality on several types of projects, particularly lighting and specialized electrical work.
Can you work in an occupied or operational building?
Yes. Our projects are designed to fit into the site’s operational reality, with rigorous planning, adapted coordination and particular attention to operational continuity.
What are the benefits of a building energy modernization?
The benefits vary depending on the project, but generally include reduced operating costs, improved facility reliability, better comfort, decreased of energy losses and a concrete contribution to decarbonization objectives. CTA: Get your free energy assessment to estimate your savings potential
What work is eligible for energy efficiency incentives in Canada?
Work eligible for energy efficiency incentives in Canada often includes audits, recommissioning, building envelope improvements, mechanical system modernization, energy optimization and, more generally, decarbonization projects. As criterias vary from one program to another, it is important to validate the eligibility early to secure available financial incentives.
E’nergys helps you to quickly identify eligible work, structure applications and maximize incentives to make your project simpler, more profitable and easier to launch.
Where to begin an energy modernization project for a building?
The right starting point is generally a building energy audit to identify the most energy-intensive equipment, the sources of los, and actions to prioritize. This first step allows to define a clear roadmap, taking into account potential savings, available subsidies, technical constraints and return on investment.
E’nergys supports you from the outset to structure an energy modernization project that is realistic, profitable and adapted to your building.
