Industry News | Creating Shenzhen's First Ultra-Low Energy Consumption, Super High-Rise Building with Photovoltaic Power Generation

Project Overview

The Runshihua (Shenzhen) Headquarters R&D Building project is located in Longcheng Street, Longgang District, Shenzhen. The construction land area is 9000.44 square meters, consisting of a 27-story (127.90m) R&D office building (Building A), a 14-story (61.95m) dormitory building (Building B), a three-story podium, a two-story underground parking garage, and equipment rooms. The project uses unit photovoltaic curtain walls, prefabricated materials, and is built to the three-star green building standard to create an ultra-low energy consumption and green building. After completion, it will promote R&D in the fields of clean energy and new energy, contributing to Shenzhen's green development and the demonstration of carbon peaking and carbon neutrality.

Technical Approach

1. The project uses BIPV thin-film photovoltaic curtain wall power generation glass to form a shading system, innovatively achieving factory prefabrication of photovoltaic curtain walls, integrating light collection, shading, and power generation, aiming to create Shenzhen's first ultra-low energy consumption, super high-rise building using photovoltaic power generation.

(Note: BIPV technology, namely Building-Integrated Photovoltaics, its core concept is to deeply integrate photovoltaic building materials into the initial stage of building planning and design, making photovoltaic power generation run through the entire life cycle of the building from planning, design, construction to operation and maintenance. Unlike traditional methods, BIPV does not simply install photovoltaic modules on existing buildings, but through photovoltaic building materialization, making power generation an indispensable function of the building itself.)

2. Using eQuest energy consumption simulation software for annual hourly energy consumption simulation, actively responding to the national call for green and low-carbon development.

3. Using prefabricated components, combined with the "aluminum mold + climbing frame" construction process, greatly improving construction efficiency, reducing construction risks, optimizing resource allocation, using BIM technology, VR technology, smart construction sites and other ten new technologies in the construction industry and other "four new" technologies, using two-construction one-time molding, pre-closed post-pouring belts and other lean construction measures to empower and enhance the project construction, and promote the upgrading of fulfillment.

4. Innovating and improving the design of internal and external spaces of the building, including innovations in building layout, spatial zoning, light utilization, and ventilation design.

5. Innovating in the selection, application, and manufacturing of building materials to improve the quality, durability, environmental protection, and aesthetics of the building. This includes developing new materials, exploring sustainable materials, and utilizing smart materials to meet the ever-evolving needs of buildings and environmental requirements.

With the continuous progress of technology and the continuous expansion of application fields, future BIPV components will develop towards high integration, not only achieving efficient power generation, but also integrating intelligent shading, aesthetic customization and other composite functions, breaking through the design bottlenecks of ultra-narrow frames and curved shapes. Building-integrated photovoltaics is expected to lead the building industry towards a greener and smarter future.
