The Big Problem We Solve

Seven percent of the coal, oil and natural gas burned in the U.S. are used to heat, cool and ventilate commercial buildings. Nearly all commercial heating and cooling systems are combined with ventilation (HVAC), but, sadly, these systems have inefficiencies built in and so use much more energy than necessary.

We think energy efficiency is of paramount importance. Carbon dioxide from burning fossil fuels is a leading contributor to global warming and that’s not okay with us. At Ventacity Systems, we’ve engineered a cleaner, more efficient solution to your ventilation needs.

Your Building with DOAS/HRV = Efficient, Comfortable, Healthy

People need fresh, clean air inside where they live and work. Ventacity produces dedicated outdoor air systems (DOAS) with heat recovery ventilation (HRV) – the most efficient way to keep a building, and the people in it, healthy and comfortable.

Ventacity’s products enable  HVAC engineers to design buildings that reduce energy use by 50% by separating ventilation from air conditioning and applying heat recovery technology along with heat pumps to a building. If fully deployed, commercial heat recovery systems could reduce US carbon dioxide emissions by 220 million metric tons each year. That’s the same global warming impact as removing 19% (49 million) of US passenger cars from the road.

The Solution: VS1000RT. The first UL, CSA and Passive House Certified counterflow HRV in North America

Our flagship VS1000RT is an intelligent dedicated outdoor air system that combines ventilation and heat recovery with a level of efficiency that puts it in a class of its own. Suitable for offices, schools, restaurants, multi-family and assembly spaces, it is ruggedly engineered for commercial rooftop application and provides up to 1000 cfm of fresh air to the building.

How We're Different

The VS1000RT is distinguished from all other similar products by its:

High performance heat recovery – utilizes high performance counterflow heat exchanger, motor and fan technology.

Intelligent controls—When connected to carbon dioxide, temperature, humidity, VOC and occupancy sensors optimize ventilation, providing just the right amount of fresh air when and where needed for maximum health and comfort.

Rooftop Ready Rugged Design – Engineered for the harsh environment of rooftops but also can be located next to or within the building.
