Building in Use - Economical Aspects
The economic evaluation of a building should take into account the whole lifecycle, i.e. costs incurred for investment, maintenance and heating, as well as for disassembly and deposition respectively recycling of materials.
Life-cycle cost analyses for clay brick constructions give very positive results (see
e.g. D-A-CH Ökobilanz Ziegel, Dr. Manfred Bruck, 1996). Solid (monolithic) brick walls
and cavity walls (incorporating mineral wool insulation) show low lifecycle costs on
account of their very low maintenance and their ability to be disassembled and recycled.
Higher lifecycle costs are often associated with walls that have external insulation which
has to be renewed a number of times during the life of the building.
Lifecycle costs are closely linked to the heating energy consumed by a building so they will also be influenced by the type of energy used, whether electricity, oil, natural gas, renewable energy or district heating.
