- ‘Almost zero’ – CO2 H-beams to be used for housing projects
- Emissions reductions of 1,580 t per year expected
Japan Metal Daily: Tokyo Steel has adopted the low-CO2 steel material, ‘almost zero’, as a standard building material for the rental housing business of Architect Developer (ADI), which handles the development and management of rental apartment buildings. This is the first time that low-CO2 steel materials have been made standard in the rental housing industry.
It was introduced for the first time in February 2025, and will be switched sequentially to all properties (about 100 buildings per year) scheduled to start construction after May 2026. As a result, CO2 emissions from the frame manufacturing stage per model building (18 households) were reduced by 23.3% to approximately 52.1 tonnes. It is expected to reduce about 1,580 t per year.
Through this initiative, ADI hopes to contribute to the promotion of decarbonisation in the construction sector and the spread of environmentally friendly housing.
ADI plans to switch to ‘almost zero’ H-shaped steel used for beams in the frame of steel rental housing. Beams account for about 25% of the weight of the frame, and the plan is to increase the emission reduction effect by switching major components. By applying it to about 100 buildings per year, it is expected to reduce CO2 emissions by about 1,580 t per year, which is equivalent to the annual absorption of about 11.30 thousand cedar trees.
