Commercial Glass Greenhouse
Venlo Glass Greenhouse
Under gutter height: 21′ 3″ to 26′ 3″ (6,5m to 8m)
A true concentrate of innovation, the Vermax Commercial Glass Greenhouse incorporates patented energy-efficient climate management technology, designed to achieve carbon neutrality. Designed for tomorrow’s agriculture, it is fully compatible with automated processes to overcome labor shortages. Its Canadian-engineered structure ensures maximum weather resistance, while its advanced design makes it a preferred choice for research projects, specialized production and demanding environments. Vermax is the avant-garde greenhouse of the future.
Semi-closed Glass Greenhouse
Greenhouse Gas Reduction Up to 70%
Coefficient of Performance 7,5
Its advanced energy storage system can achieve a peak coefficient of performance (COP) of up to 7.5 due to its plug-and-play designs that connect to thermal recovery projects. This allows for efficient thermal recovery, which boosts energy efficiency and cost savings.
Aiming for Nearly Zero Energy Building (NZEB)
The Vermax is designed with Nearly Zero Energy Building (NZEB) principles, combining passive design strategies and ground-breaking energy technologies to reduce consumption and maximize efficiency.
Water Management
A revolutionary circular water treatment system. This ensures zero wastewater and eliminates the need for additional water intake after the initial launch—an essential step toward sustainable agriculture.
Circular co2 Supply
From this air to flourishing production, Vermax recycles captured CO2 on-site from ambient air. This technology leaves the grower with a clean,
concentrated stream of C02 and helps avoid new emissions.

Case Study: Building to Face Climate Change
The new Vegpro greenhouse represents a significant advancement for the company. Equipped with the latest technologies and designed with sustainability in mind, this greenhouse addresses the current challenges of agriculture, particularly climate change, while providing high-quality products to our customers year-round. Through innovation, automation, and environmental stewardship, Vegpro is positioned at the forefront of sustainable vegetable production in Canada.
Vegpro aims to increase its productivity, reduce its ecological footprint, and continually improve the quality of its products. The greenhouse, covering 5.2 hectares, is designed to produce up to 3.5 million kilograms of lettuce per year, which is 68,000 kg per week, representing about 62 million
2-ounce salad portions annually.

Sustainability at the Core.
At Harnois Greenhouse, sustainability is at the core of our mission as we strive to shape the future of high-tech greenhouses. Our commitment to carbon neutrality, energy efficiency, and resource optimization drives every innovation we develop. By integrating cutting-edge, patented environmental technologies into our proprietary structures, we are paving the way for a more sustainable agricultural industry.
At Harnois, we are committed to reducing our carbon footprint while optimizing the energy efficiency of our commercial glass greenhouses. Our commercial glass greenhouse maximizes natural light use and integrates advanced technologies, such as high-efficiency heating and cooling systems, to minimize energy consumption. We create sustainable agricultural solutions with our partners and clients and aim for ambitious carbon neutrality goals. Discover how we are shaping the future of agriculture with eco-friendly and energy-efficient solutions.
Harnois designs and manufactures commercial glass greenhouses adapted to any climates, where temperatures can drop significantly. These commercial glass greenhouses are ideal for growing highly demanded soft fruits, (strawberries), vegetables and flowers. Our design also allows for the integration of all climate control and automation equipment directly within the greenhouse.
The roof and structure are made from high-quality materials to support the weight of the glass.
Carbon-neutral, energy-efficient and sustainable commercial glass greenhouses
Precision in every component we utilize, especially in the construction of roofing and ventilation systems, enables exact climate control for superior growing outcomes. Each commercial glass greenhouse we create is uniquely designed and meticulously calculated, ensuring a custom fit tailored to your business’s requirements.
A testament to this vision is our latest project with VegPro International in Sherrington, QC—a 5.2-hectare commercial glass greenhouse designed for year-round lettuce production. This facility will produce 3.5 million kg of lettuce annually, demonstrating how advanced greenhouse technology can revolutionize food production while minimizing environmental impact. With every project, we push the boundaries of sustainability, ensuring a greener future for generations to come.
