The Guanlan Public Cultural Center has been recognized as Shenzhen's first benchmark project for coordinated pollution and carbon reduction in a public building, marking a milestone in Longhua District's efforts to promote greener urban development.

According to the Longhua Administration of the Shenzhen Municipal Ecology and Environment Bureau, the project represents the district's first breakthrough in establishing a benchmark model for emissions reduction in the building sector.

Reducing pollution and carbon emissions from buildings remains a major challenge for densely populated urban districts because of buildings' large footprint, high lifetime energy consumption and complex management requirements.

To address these challenges, Longhua has pursued a full-chain approach covering design, construction and operation.

At the design stage, new buildings in key development areas are required to meet at least China's two-star green building standard, while large public buildings must meet the more stringent three-star standard.

The Shenzhen Art Museum (New Venue) and Shenzhen Library North Division have both received national three-star green building certification. The projects have achieved energy savings of 68% and have reduced annual operating costs by more than 1.6 million yuan (US$223,000).

Longhua has also accelerated the adoption of digital technologies in construction. The district has expanded the use of Building Information Modeling (BIM) and City Information Modeling (CIM) systems while promoting modular and prefabricated building methods.

At the Fucheng South Industrial Area project, factory-prefabricated components helped triple construction efficiency while reducing dust emissions by more than 17% compared to conventional construction methods.

The district has also focused on improving the environmental performance of completed buildings. Supporting facilities at the Shenzhen North Railway Station transportation hub have been equipped with a low-carbon operations system that saves more than 8 million kilowatt-hours of electricity annually and reduces carbon emissions by nearly 3,900 tons.

Together, these projects demonstrate Longhua's efforts to integrate green and low-carbon principles throughout the entire lifecycle of buildings, helping establish a model for sustainable urban development in Shenzhen.
