As climate change becomes more severe, countries around the world are working to reduce carbon emissions, and the trend toward zero-emission buildings has become an important part of the construction industry. The European Commission has proposed amending the Energy Performance of Buildings Directive (1) to move from the current "Nearly Zero Energy Building" (NZEB) to "Zero Emission Building" (ZEB), in order to better align building energy efficiency requirements with climate neutrality goals and promote the development of sustainable buildings. The requirements of ZEB are extremely high energy effiency, fully covered by renewable energy, and no carbon emissions from fossil fuels. This means that buildings need to use very low energy and meet their energy needs through the use of renewable energy, achieving zero carbon emissions. According to the International Energy Agency's report, the building sector accounts for about 36% of global greenhouse gas emissions, making it one of the largest sources of emissions. These emissions come from energy use in buildings, including heating, cooling, lighting, and appliances. Therefore, "Zero EmissionBuilding" (ZEB) is a necessary condition for achieving the vision of a net-zero city by 2050.
Moving to the United States, the government of Chicago, known as the city of skyscrapers, announced on August 8, 2022 (2) that all public buildings and sister agencies, such as Chicago Public Schools, the Chicago Transit Authority, and the Chicago Housing Authority, will switch to using 100% renewable energy by 2025. This historic investment will largely come from a new utility-scale solar farm, which will be built in compliance with the Climate and Equitable Jobs Act (CEJA) standards. The city will also seek local projects to invest in clean energy in Chicago. In 2018, the organizing efforts of the Ready For 100 Chicago Collective directly led to Chicago's first commitment to transition to renewable energy. How can skyscrapers become zero-emission buildings? This is a major challenge for the construction industry, and it is clear that the building industry needs to innovate further to achieve the vision of a net-zero city by 2050. The vision of a "Net Zero City" requires more innovation in renewable energy technology to achieve it.
To achieve "zero-emission buildings," Taiwan Perovskite Solar Cell Technology (TPSC) has partnered with Kyopt to launch "LuBan 1" The design of LuBan 1 is based primarily on perovskite solar energy. Perovskite solar cells are a third-generation solar cell technology that converts solar energy into electricity using the light absorption characteristics of perovskite materials. Compared to traditional silicon solar cells, perovskite solar cells have higher photoelectric conversion efficiency and lower manufacturing costs, and can also achieve multiple designs such as transparency, flexibility, and color, making them more widely applicable.
description: The concept illustration of "Luban 1" as a zero-emission building with a main energy source based on perovskite solar cells.
The roof of "LuBan 1" uses high-efficiency perovskite solar cells to maximize solar power generation, while the building's three sides use a combination of transparent and semi-transparent perovskite solar cells to fully utilize the building's facades for power generation. The transparent perovskite solar cell uses TPSC's exclusive transparent electrode design, which effectively maximizes the solar cell's power generation area. The building's appearance can also be freely combined according to the building's design, meeting the standards of zero-carbon buildings while also considering the aesthetics of the building.
In addition, perovskite solar energy can generate electricity in weak light conditions, and the indoor tables in LuBan 1 can effectively convert indoor light into electricity, driving various appliances and sensors to improve the building's energy efficiency. Combined with energy storage systems, "LuBan 1" can significantly reduce external energy use and further increase the building's self-sufficiency ratio to meet the standards of zero-carbon buildings.
TPSC looks forward to showcasing this innovative design concept product at the 2050 Net Zero City Expo from March 28 to 31 at the Taipei Nangang Exhibition Hall. We hope to explore with industry experts and guests how to build a more sustainable and environmentally friendly future for net-zero cities.
