In the picturesque mountain town of Karuizawa, Japan, a unique and innovative house has been constructed using a new type of CO2-absorbing concrete. Made by replacing part of the cement with an industrial by-product and adding CO2 absorbing materials, this groundbreaking material reduces emissions from the production process while achieving carbon neutrality during the curing process.
The house is located on a 110-meter long plot of land along the road in Karuizawa, one of Japan’s oldest and most famous mountain resort towns. The strength of this new type of concrete is equivalent to regular concrete, making it an ideal choice for construction projects.
Nendo, a design company, was responsible for designing the concrete walls to resemble screens, with the angle of the blocks adjusted to control visibility. By incorporating carbon-absorbing concrete into construction, this project aims to contribute to reducing CO2 emissions in the world. With the cement and concrete production industry projected to generate 8% of total carbon emissions by 2023, innovations like CO2-absorbing concrete are crucial for sustainability efforts.
This use of sustainable materials in construction can help minimize the environmental impact of future projects while reducing emissions from the cement and concrete production industry.
