Ecology |
The mining, extraction and purifying of metals damage the environment to a great extent. |
The production of concrete and concrete columns damage the environment somewhat. |
A tree is a renewable resource, which during it's growth reduces the greenhouse gases and produces oxygen. |
|
Disposal |
The disposal of steel is difficult and expensive. |
The disposal of concrete is difficult and expensive. |
Wood can be disposed of fast and ecologically by burning. The result is heat energy. |
|
Firesafety |
At a particular temperature steel buckles and the structure collapses. Heated steel radiates heat around it for a long time. Wooden lining can make the structure safer. |
At a particular temperature concrete will break and splinter and the steel reinforcement will bend. |
Wooden column will carbonise but not burn. It will keeps it's load bearing properties much longer than the steel or concrete columns. |
|
Installation |
Steel columns weigh enormously, joining other components to them is hard. |
The production / installation is slow as the column is poured in place. |
Wooden columns are significantly lighter than their competitors and other structures can easily be joined to the wooden columns. Electronics, tubing, wiring can be built inside a hollow wooden column. |
|
Appearance
|
Modern. A steel column can also appear cold.
A mixture of cold steel & warm wood offers another approach. |
Concrete atmosphere? |
A wooden column is warm and cozy. By adding groves to the surface you get different appearances.
A mixture of cold steel & warm wood offers another approach. |
|
Wirings |
The steel column is hollow wiring can easily be installed. Holes only with special drills. |
Challenging to install wiring in a concrete column. |
A wooden column can be made hollow, without loosing any of its bearing capacity. Wiring easily installed, also drilling of new holes requires no special tools. |
