Solar and Gravity Powered Energy Nodes for Urban Vitality
Merit Award – The 10th Bi-City Biennale of Urbanism\Architecture (Shenzhen)
Creative Renovation Proposal, 2025
Dis-charge · Re-charge is an innovative urban intervention designed for the main street of Huaqiangbei, Shenzhen. The proposal reimagines the “China’s No. 1 Electronic Street” as a dynamic public space powered by a closed-loop energy system. By integrating high-efficiency solar panels with a pioneering gravity battery storage system, the project transforms a sun-exposed, underutilized urban area into a shaded, socially vibrant hub by day and an illuminated, interactive venue by night.
How can Huaqiangbei become more social, sustainable, and thereby more innovative?
This proposal answers by creating a space where energy production, storage, and consumption are visible and participatory. The design not only provides practical amenities—such as seating, phone charging, and an open-air theater—but also turns energy flow into a public spectacle, fostering awareness and engagement around sustainable urban living.
Sunlight Analysis
The site experiences intense sun exposure due to its location next to Shennan Avenue. Solar and shading strategies were developed based on solstice analysis to turn this challenge into an opportunity.
Sketch Section
South-facing solar panels are angled to maximize energy capture while creating shaded space below—transforming a solar liability into a sustainable and social asset.
Site Strategy
A solar canopy connects with existing structures, offering sheltered zones for pedestrians and activating underused areas for community use.
New Gateway
The structure acts as a new gateway for Huaqiangbei—a tech-integrated landmark that guides pedestrian movement and embodies energy flow.
Energy System
A dual-mode system charges the gravity battery by day, raising the screen. At night, it lowers to power an LED display and lighting, visualizing the energy cycle.
Day-Night Cycle
A continuous energy loop: solar power is stored by day and used from 5–9 PM to light the screens and support public activity.
Section & Materials
Lightweight prefabricated structures and non-invasive foundations allow quick assembly while protecting underground infrastructure.
