“My motivation for inventing Artus was to solve one of society’s greatest challenges: to reduce the amount of energy we all consume.”

Significant Energy Savings

can deliver a 63% reduction in energy for air conditioning when compared to a conventional fan coil unit. This is a reduction of 21% of a building’s regulated energy.

Annual operational energy for Air Conditioning

achieves a fan energy reduction of 89% when compared to FCU systems. The unique design of the unit and variable nature of the fan speed make this possible.

Fan energy is measured as specific fan power (SFP) in watts per litre per second. To be just compliant with the building regulations, Part L, you need 0.30. A good standard fan coil unit is 0.25. The best we could find was 0.19. The seasonal average for is 0.055.

The operational energy use with is comparable to or lower than an active chilled beam system. Both use elevated chilled water temperatures and Artus uses fans with a very low SFP instead of the additional primary air required by active chilled beams.

Energy modelling shows that just changing from a compliant FCU system to , without taking advantage of elevated chilled water temperatures and low grade heating, would reduce annual regulated energy by 10%. Under the current BREEAM for Refurbishment and fit out this would give an additional 3 BREEAM points.

Artus Optima, is a demand-based control design methodology that maximises energy savings in operation. Using this with and elevated chilled water temperatures with low grade heat, would give a 63% reduction in energy for cooling and heating. Under the current BREEAM for Refurbishment and fit out this would give an additional 7 BREEAM points.
