>> Highlights of the Teams <<


In this competition, the solar residences of the eight university teams showcased innovative applications of Cadmium Telluride (CdTe) photovoltaic (PV) power generation building materials. Various architectural photovoltaic integrated applications, such as solar curtain wallssolar roof tilessolar glass sunrooms, solar glass railings, solar skylights, solar sunshades and Building Integrated Photovoltaics (BIPV) integrated roofs, were observed in these solar homes. Each team demonstrated profound wisdom by designing solar residences that are both functional and comfortable, presenting a fresh perspective on solar energy technology.






 Overview

Team THU

From Tsinghua University


The "Grassland Ark" roof incorporates 352 units of aluminum-mimicking solar photovoltaic glass building materials (including 128 units of non-standard sizes), achieving a complete substitution for traditional construction materials, covering the entire roof. The continuous delivery of green electrical energy through these aluminum-mimicking photovoltaic building materials not only aligns seamlessly with the architectural aesthetics of the "Grassland Ark" but also integrates the functionalities and requirements of photovoltaic power generation, building materials and decorative effects into a cohesive whole.

Team BJTU

From Beijing Jiaotong University, Loughborough University


The residential project "BBBC" from Tsinghua University adopts photovoltaic as the primary energy source, employing a multi-energy complementation approach with "hydropower + fossil energy + biomass + wind energy" to address uncertainties in scenarios. This ensures resilient energy supply, achieving zero energy consumption while allowing energy feedback. The entire building, from power supply to electrical appliances, utilizes direct current, realizing a truly all-DC building. The project features 104 pieces of cadmium telluride solar photovoltaic glass in three different colors and transparencies – black, field yellow, and sky blue. These harmonize seamlessly with three colors of sunshades, creating a natural and aesthetically pleasing appearance highly appreciated by the participating teachers and team members.

Team R-CELLS

From Tianjin University, Oslo School of Architecture and Design, Tianjin Chengjian University


R-CELLS residence optimizes rooftop space, installing 52 standard photovoltaic building material products and 10 vibrantly colored transparent solar photovoltaic glass on an asymmetrical V-shaped roof. With a total installed capacity of approximately 35 kilowatts, the annual electricity generation is four times the predicted consumption. Supported by a battery storage system, the surplus electricity can be transferred to the grid, enabling the building not only to meet daily electricity needs but also to serve as an "energy producer" in power transactions. This feature reduces user energy costs and demonstrates high economic efficiency.

Team Qiju 3.0

From Xi'an University of Architecture and Technology, Southwest University for Nationalities


Team Qiju 3.0 showcases a rich variety of solar photovoltaic building integrated applications, including solar roofing, sunshade panels and photovoltaic railings. The solar roofing employs 160 standard solar roof tiles building material products, while the sunshade panels and photovoltaic railings feature 26 pieces of 20% transparent solar photovoltaic glass in different sizes and thicknesses. The application of photovoltaic sunshade panels and railings represents a breakthrough attempt in using solar glass building materials in green building applications, enriching the future scenarios of photovoltaic building applications.

Team BJTU

From Harbin Institute of Technology


The "Modular Sustainable Magic Box" residence is equipped with 149 standard-sized solar photovoltaic glass building material products, including 40 pieces of 20% transparent colored solar glass in red, yellow, blue, and green. These are installed on the rooftop & terrace, serving as both shading and decorative elements. The solar photovoltaic system is complemented by a battery system ensuring a minimum of 48 hours of operation without sunlight. Operating in grid-tied mode, it utilizes grid electricity when solar power is insufficient and feeds excess electricity back to the grid, maximizing energy efficiency.
