Waterloo delivers ‘VAV-VAV-VOOM’ through variable air volume


These days, buildings are more intelligent. Today we expect automatic lighting to turn on and off to reduce wastage when nobody is in a room. We offer the ability to control air flow in the same way using Variable Air Volume (VAV) for long-term energy efficiency benefits.

VAV monitors temperature and humidity and adjusts the air volume automatically to maintain a environment suited to the needs of the specific room. That means keeping a room comfortable however many people are in it, or preserving the conditions vital to protect materials in server rooms, hospitals or laboratories.

This also makes running the building more efficient, because changes in volume are made quickly to maintain the desired temperature, helping large buildings such as offices, factories, schools, hospitals or high-rise developments.


The care-free system is growing in popularity, as architects and building engineers tap into VAV to save time, reduce costs and hit energy efficiency targets to get the best from buildings.

Today’s air flow systems are cleverly engineered to direct the right volume of air within any room in a building. Variable Air Volume adds the ability to control the when as well as the where.

The industry is really embracing VAV because there’s the recognition of how convenient it is. We’re seeing particular interest from architects and developers seeking systems that add value and reduce costs to the building’s long-term performance, as well as for rooms with precise requirements such as server rooms or scientific and medical facilities.


Waterloo supplies VAV alongside our range of air terminal devices for a complete air movement system tailored to the specific needs of the building.

Getting VAV right means understanding how a building will be used, on a room-by-room basis. At Waterloo, we engineer the products needed, test them in our in-house lab and provide technical back-up so that architects, builders and engineers get the most effective performance from a VAV system.

The range of volume controllers also includes Constant Air Volume (CAV), volume flow rate controllers, sensor-activated dampers and secondary attenuators. Options include acoustically lined versions for reduced sound.
