"Guangxi Green Building Evaluation Standard" stipulates the basic requirements and grade division of green building evaluation in Guangxi Zhuang Autonomous Region. It is applicable to the evaluation and grading of green buildings in residential buildings, public buildings, office buildings, shopping malls and hotel buildings within the administrative area of Guangxi Zhuang Autonomous Region. Among them, what are the requirements of Guangxi Green Building Evaluation Standard for the use of materials and material resources for green public buildings? The following is an introduction to the material saving requirements of green public buildings in Guangxi brought by the construction network for your reference.

The content of harmful substances in building materials meets the requirements of GB 18580 ~ GB 18588 and GB 6566.

The architectural modeling elements are simple, and there are not many decorative elements.

The weight of building materials produced within 500 kilometers of the construction site accounts for more than 65% of the total weight of building materials.

Cast-in-place concrete adopts ready-mixed concrete.

Reasonable use of high-performance concrete and high-strength steel as building structural materials.

Classify the solid wastes generated in the process of building construction, demolition of old buildings and site cleaning, and recycle and reuse reusable materials.

The recyclability of materials should be considered when selecting materials in architectural design. Under the condition of ensuring safety and no environmental pollution, the weight of recyclable materials accounts for more than 10% of the total weight of building materials used.

Civil engineering and decoration engineering are designed and constructed in an integrated way, without destroying and dismantling existing building components and facilities, and avoiding repeated decoration.

Flexible partitions are used in offices and shopping malls to reduce material waste and garbage generation during redecoration.

On the premise of ensuring performance, the proportion of building materials produced from waste materials is not less than 30% of similar building materials.

The reinforced concrete structure adopts new materials-saving technologies such as cast-in-place concrete hollow floor technology and prestressed reinforced concrete structure.

Mortar adopts ready-mixed mortar or dry-mixed mortar.

Intensive production of building materials, standardized components and equipment; The structural design of the building adopts the general standardized structural components produced by industrialization.

Use new wall materials.

Organic heat insulation materials are not used.

Adopt a building structure system with little resource consumption and environmental impact.

The utilization rate of reusable building materials is greater than 5%.
