What Are the Environmental Acceptance Criteria for GRC Projects? Green Building and Qinglong Group's Sustainable Development Practices

The environmental acceptance of GRC projects has gone beyond the traditional scope of hazardous substance limits for materials, evolving into a comprehensive evaluation system covering "green material properties, energy-saving and consumption-reducing production, environmentally friendly installation, and whole-life-cycle environmental impact of buildings." Based on China's national green building evaluation standard (GB/T 50378) and international standards such as LEED and WELL, Qinglong Group summarizes the core environmental indicators of GRC projects as: radionuclide limits of the materials themselves (internal exposure index Ira ≤ 1.0, external exposure index Iγ ≤ 1.0) and volatile organic compound (VOC) emission rates; energy consumption per unit product, wastewater recovery rate, and comprehensive solid waste utilization rate in the production process; dust and noise control during construction; and ultimately their contribution to building energy efficiency (e.g., as integrated thermal insulation and decoration panels). In the Shenzhen Pingshan High-Tech Zone Comprehensive Service Center project (Luban Award, Three-Star Green Building), our GRC products and systems contributed significant points to the project's green rating. Environmental protection is a compulsory course for modern buildings.

Green properties of the material itself are the foundation

GRC is mainly composed of cement, sand, and fibers, and is itself an inorganic environmentally friendly material. Its radioactivity indicators must be strictly tested to ensure compliance with the national Class A decoration material standard (no restrictions on production, sales, or scope of use). The pigments, admixtures, and other additives used must meet national standard limits for hazardous substances (such as formaldehyde, benzene, and heavy metals). We give priority to raw materials certified under the "China Environmental Labeling Product" program.

Energy conservation and emission reduction in the production process are key links

Environmental acceptance focuses on the greenness of the product manufacturing process. Through process improvements, we have reduced comprehensive energy consumption per unit product by 15%; established a water circulation system with a production wastewater recovery and utilization rate of over 90%; and waste materials (such as offcuts) are crushed and recycled as aggregate, achieving a comprehensive solid waste utilization rate of over 95%. All these figures are verifiable environmental indicators.

Environmental friendliness of construction and installation is increasingly important

On-site installation requires dust control (e.g., wet cutting), noise control (well-planned construction schedules), and construction waste management (sorted recycling). GRC dry-hanging installation itself generates relatively little dust and waste, making it an environmentally friendly construction method. We require all project sites to meet municipal-level "Civilized Construction Site" standards.

Contribution to building green performance is a higher requirement

As the building envelope, the thermal insulation, heat insulation, and shading performance of GRC curtain wall systems directly affects building energy consumption. When GRC integrated thermal insulation and decoration panels are used, their contribution to improving building energy efficiency can serve as an environmental bonus. In addition, GRC's durability and low-maintenance characteristics reduce the environmental burden of material replacement and maintenance over the whole life cycle, making them important green attributes.

The environmental acceptance of GRC projects is a comprehensive consideration spanning the entire industry chain. Through green materials, clean production, civilized construction, and long-lasting products, Qinglong Group is committed to providing customers with green building solutions in the true sense.
