ECONOMIC PERSPECTIVES
The building can be closed quickly as the rafters and roof slabs can be mounted immediately after the erection of the steel plates The interest costs during construction are heavily reduced due to the shorter construction period.
The building costs are lower than for ordinary traditional buildings, i.e. 10-12% for small dwellings. The savings per m2 are substantially larger for big houses because the costs of the installation of the forced ventilation and the cathodic protection of the steel plates are comparatively smaller than for the necessary central heating. The prices for the erection of large outer wall spaces are cheaper for buildings based on the ThermoLogica principle than for traditional buildings. The steel elements are considerably lighter and less vulnerable, and much easier to handle on the building site.
The
architects, Dissing + Weitling, chose to construct the building project
in Ballerup as a housing construction entirely in steel without any
use of concrete or bricks in harmony with the late Professor Arne Jacobsen's
intentions. By means of a thin profile at the end they were coupled with bolts to the supporting steel plates in the outer walls. Strong Neoprene partitions offering thermal protection at the bolt joints result in minimal cold conductors.
The steel plates can be made to measure from the steelworks so that there will be no waste of materials on the building site. If pieces are cut out for windows and doors after the erection of the house on the building site, these may be sent for recycling or remelting. If only supporting, vertical steel plates are used between the windows and the windows/doors and these are mounted in vertical bands, there will be no waste of steel plates. Thinner steel plates may be inserted above and below the windows and doors, e.g. coloured plates, as the value of the transportation of heat is deteriorated because the windows/ doors obstruct the transportation.
When
a traditional house is demolished, it is difficult and costly to recycle
or destroy for instance bricks and concrete for environmentally sound
waste. |
