| Structure system |
Light steel house |
Concrete frame work house |
Wooden house |
| Main structure |
light steel structure |
cast-in-place reinforced concrete framework and structure |
pine, mortise and tenon linking structure |
| Unit Price for construction |
$220/square meter |
$270/square meter |
$680/ square meter |
| Lifetime |
more than 90 years |
less than 50 years |
less than 20 years |
| Anti- earthquake performance |
9 grade anti-earthquake |
6 grade anti-earthquake |
common anti-earthquake performance |
| construction cycle calculated in 300 square meters |
about 50 days , crossing construction, the schedule will be less affected by weather factor |
about 6 months, concrete and mortar solidification need some time, it will be affected by weather factor |
about 3 months, crossing construction, the schedule will be affected by weather factor |
| Valid area |
more than 90% |
less than 82% |
less than 78% |
| Heat insulation performance |
without structural cooling or thermal bridge, the energy performance is higher than 65% |
common performance, the energy performance is less than 50%, it needs to add external wall for heat insulation |
A bit weak, especially in winter |
| Materials recycling rate |
100% main structure can be recycled, 80% surrounding materials can be recycled |
except the reinforcing bars, others components cannot be recycled, which would produce architectural rubbish |
it destroys the forest, weak corrosion resistance, low recycling rate |
| Waterproof and leakage resistance performance |
Adopt advanced materials and procedures for waterproof treatment, the overall house is good, free of leakage points. |
The overall house is good, with less leakage points. |
The overall house is bad, with many leakage points. |
| construction difficulty |
Prefabricated units at the factory, it can save labor & time when you assemble them on the spot. |
It needs more lifting equipment & construction personnel, after maintenance, it can be decorated, but there's great limit, easy to destroy the structure during decoration. |
Easy to construct, during decoration, you also can have construction. |
