6. Economic and ecological aspects
6.1 Economical and ecological thickness
The cost of operating thermal fluid equipment is proportional to the cost of the energy expended to limit heat loss.
Heat loss decreases with insulation thickness. The investment required for this insulation increases with the thickness. The total cost passes through a minimum for a certain thickness, known as the economic insulation thickness.
If we add GHG constraints (market and carbon tax), we increase operating costs, which makes it possible to determine an ecological insulation thickness.
Given the number of parameters to be taken into account, such studies are rare, and the last ones took place in the 1970s, after the...
