In the future, carbon-absorbing concrete will become the primary material of construction. Concrete using this technology reduces the carbon footprint of buildings and helps combat climate change by actively absorbing CO2. This technology ensures a comfortable indoor climate and allows buildings to regulate temperature and improve air quality passively. In the design of the future Department of Energy, through the exploration and innovation of carbon absorbing concrete technology, sustainability can be achieved by lling excavated concrete to rearrange the required indoor space continuously. By combining these design concepts and technologies, the future Department of Energy Building will become a fully functional, environmentally friendly modern oce building that can cope with future changes. It will fully embody the concept of sustainable development and innovative spirit.
