Purchase price
Price is a crucial factor for building developers and architects.
A water mist system will normally have higher material costs due to the requirement for stainless and corrosion-free components, but can still be cost-effective when considering installation costs.
A report from Grønn VVS (12-2024) shows that the cost of a low-pressure water mist system is only approx. 4% higher than for a traditional sprinkler system. With increased use, these costs are expected to be reduced. The same report refers to an office building of approx. 3,400 m², where the difference between conventional sprinkler and low-pressure water mist amounted to a weight difference of 8.5 metric tons. It takes longer to transport, unload, transport into the building, lift and secure an extra 8.5 tons.
By referring to the water mist standard in the tender to the contractor, we are convinced that the purchase price will be competitive in most projects. The larger the project, the more water mist benefits.
Quality, maintenance and life cycle costs
Most building developers are concerned with quality and total investment costs. With low-pressure water mist, you get a fire suppression system for less than half the price when comparing the life cycle costs to a traditional sprinkler system built with carbon steel piping!
Our systems use only stainless steel or approved plastic based pipes and fittings. This means less need for replacements over time with significantly lower maintenance costs. A traditional fire suppression system with carbon steel pipes must be replaced at least once, if not twice, compared to the life of a stainless steel system.
When remodeling or renovating, stainless steel pipes and parts will be reused, which is good for both the environment and your wallet.
Space-saving aesthetics
Low-pressure water mist gives architects greater flexibility in the design phase, thanks to the system's smaller pipe dimensions. It allows for more efficient use of the building's space and can possibly open for higher ceiling heights, improving aesthetics and give a room an open feel.
It is also possible to reduce floor heights and maintain the same interior ceiling height, which can save the project significant construction costs.
Efficiency on the construction site
In a typical office building of around 3,400 m², an installed water mist system will weigh approximately 1.3 metric tons, while a conventional sprinkler system with carbon steel piping will weigh approximately 9.8 tons. The difference in materials and weight will result in less storage space, simplified logistics and faster installation, which will overall help to increase efficiency on site.
Less time spent on site is something the Builder and General Contractor really appreciates!
Water consumption
A low-pressure water mist system uses around 1/3 of the water compared to conventional sprinkler systems. This not only reduces potential water damage in the event of system operation, but also reduces downtime and helps reduce the strain on the building's water supply.
Sustainability and environment
See the Green HVAC report comparing greenhouse gas emissions from fire suppression systems. The savings from a low-pressure water mist system compared to conventional sprinkler system is eye-opening!
By choosing a low-pressure water mist system, builders can reduce greenhouse gas emissions from the fire suppression system by up to 76%. This is significant when you know that HVAC represents a large proportion of emissions from buildings, up to 40%, and that a conventional sprinkler system represents approximately 1/3 of the HVAC delivery.
Anyone who is concerned about the environment and sustainable solutions should read the Green HVAC Report !
Building developer or architect?
As a building developer or architect, choosing an automatic suppression system is a balancing act between cost, quality, efficiency and sustainability.
