In the heart of Honglou commercial area in Licheng district of Jinan, capital of East China's Shandong province, a striking new structure is reshaping how cities build sustainably.

Part of the Honglou 1905 project, Jinan's largest urban renewal initiative, the dome enables dust-free, low-noise, all-weather construction, even in densely populated areas.

Developed by a joint venture between China Energy Construction Group and Licheng Urban Development Group, the project integrates modern commercial design with local heritage, ecological features, and cultural assets such as the century-old church and nearby Shandong University.

It features heat-reflective PVDF membrane materials that cut energy use by up to 90 percent, while intelligent systems monitor temperature, air quality, and safety in real time — enabling efficient, low-impact building.

This initiative reflects Jinan's broader commitment to green growth. The city has advanced projects in renewable energy, low-carbon infrastructure, and smart emissions monitoring. From green industrial parks to waste reduction programs, it is setting a benchmark for sustainable urban transformation.

The white dome is more than a construction solution—it represents a shift from traditional building methods to smart, eco-conscious innovation. It underscores Jinan's dedication to creating a livable, resilient, and forward-looking city for future generations.
