Why is light steel villa house called a new green building? There are mainly the following aspects.

1. Low carbon indicators:

The carbon dioxide emission of light steel buildings is about 480 kg/m2, which is more than 35% lower than the traditional concrete carbon emission of 740.6 kg/m2.

2. Material index:

The weight of light steel structure residential high-rise buildings is about 900-1000kg/m2, and that of traditional concrete is about 1500-1800kg/m2, which reduces the weight by about 40%. It can greatly reduce the consumption of resources such as cement and sandstone, thus greatly reducing carbon emissions in the process of mineral exploitation, smelting and transportation. Wood formwork and scaffolding are not used in the construction of light steel structure houses. If its market share increases by 5%, the deforestation equivalent to 9,000 hectares of forest can be reduced. The weight of the building itself has been reduced and about 30% of the underground pile foundations have been saved.

3. Water saving index (reducing sewage discharge):

Light steel structure residential buildings are mainly assembled and constructed on site, which can greatly reduce the discharge of water and sewage during construction. If its market share increases by 5 percentage points, it will reduce the sewage discharge equivalent to the total water volume of 10 West Lake.

4. Energy saving index (saving energy consumption):

The self-developed grouting wall has a good self-insulation function, which is 3 times the thermal insulation performance of the traditional brick wall and greatly reduces the energy consumption in operation.

5. Provincial Indicators (Improving Land Use Efficiency):

Steel structure is "tall and light", easy to realize high-rise buildings and can improve the efficiency of land per unit area. Indoor house prices rose by 5%-8%, and parking spaces in underground garages could increase by 10%-20%. Today, the social and economic value of the problem is particularly prominent.

6. Environmental indicators:

Construction site assembly to reduce noise, sewage and dust pollution; Reduce sandstone mining and construction waste emissions, protect the environment and build a new era of building civilization.
