It is still common practice to evaluate investment projects in air treatment systems, such as extraction systems, filter systems and ventilation systems, primarily based on their acquisition costs. With such an approach, only the immediately evident investment costs are considered, while the continued operating costs are not taken into account.
Our experience has shown that the investment costs only account for 25% of the cost of an air treatment system over its working life. The remainder is largely accounted for by operating costs. And of these, three-quarters are accounted for by energy costs. These are costs that often remain hidden.
That is why we are talking about the iceberg principle here.
