are chosen according to the building techniques used, e.g. bricking, building with concrete
and bad insulation, or well-insulated buildings with flat roofs.
Figure 2: Inventory volume in Swiss house building in Mm3 [FOEN 2008c]
Nearly 40 % of the building volume has been built after the year 1975. 14 % in volume of
buildings are still older than more than hundred years. In general, old buildings are rather to
find in rural regions. Periods of intensive construction took place between 1961 and 1975
with nearly 60 Mm3 new constructions per year; this continued between 1976 and 2000 with
nearly 50 Mm3 of new constructions per year. For the years 2005 and 2006, 40 Mm3 of new
constructed volume per year are estimated. In future, this figure is estimated to even out at
about 30 Mm3 [FOEN 2008c].
According to the FOEN modellings, one third of inventory volume is incorporated in
apartment buildings; together with detached houses, this percentage is near 50%. Besides,
industrial buildings make up nearly 20% of the building substance. The remaining part
consists out of service buildings, agricultural buildings and diverse constructions [FOEN
2008c].
The field in civil engineering is large. It comprises:
- Traffic: Roads, railways, trams, metro, ski lifts, funiculars etc.
- Telecommunication
- Energy supply
- Water supply and waste water
- Other: barrages, linings, military infrastructure
The following description gives an (incomplete) overview on existing and planned
underground constructions in Switzerland. Detailed material stocks are modelled in [FSO
2005] and [FOEN 2008c].
