Frame houses built with light-framed /
prefab technology. |
 |
Brick buildings built with
conventional technology. |
 |
|
| |
Environmentally friendly,
reusable. |
|
Environmentally destructive,
not reusable. |
|
 |
|
| |
Construction can be executed
year-round – even in the winter. |
|
Construction is seasonal. |
|
|
|
| |
Construction is quick and easy. Clean work thanks to dry-technology, screwed connections.
Execution deadline: usually ready for use in 3 months |
|
Time-consuming; construction can take years.
. Lots of waste and debris.
|
|
|
|
| |
Only
limited on-site work.
Guaranteed quality and precise structure
thanks to factory-assembly. |
|
Significant on-site work, which gives way to the possibility of quality problems. |
|
|
|
| |
Expected life-span
exceeds 100 years. |
|
Expected life-span is 80-100 years. |
|
|
|
| |
It is mobile, and can easily be remodeled with a small budget. Minimal tearing down. |
|
Remodeling, renovating is relatively expensive and requires quite a bit of work. |
|
|
|
| |
It is easier to control for
price changes of building materials. The final cost is easier
to calculate due to the quick construction process. 20-25%
savings compared to traditional (pl.: brick, concrete slab)
construction. |
|
The price is more difficult to calculate due to the lengthy construction period. Because of potentially higher and higher prices for materials, you never know how much the building will end up costing. |
|
|
|
| |
Overall cost lower. |

Overall cost higher. |

| |
Can be heated quickly. |
|
Efficient insulator,
but lengthy heating required. |
|
|
|
| |
The building provides better
heating insulation, and is thus more energy-efficient. For
example:
we use 54-100 kWh/m2 for heating,
30-50% savings compared to a brick wall. |
|
High bills, for example:
we use 150-220 kWh/m2 for heating. |
|
|
|
| |
Thinner walls provide greater useful floor space. |
|
Thicker walls mean less useful floor space. |
|
|
|
| |
Dependable
protection against summer heat. Easily ventilable. |
|
Conventional buildings are
slow to give off heat, so they continue to radiate it throughout the night.. |
|
|
|
| |
Reduced risk of allergic reactions due to dry plaster. |
|
People with respiratory illnesses might be sensitive to vapors emitted by moist plaster. |
