Buildings are the largest consumers of energy in the world. Under the crisis of global warming, the development of "green buildings" is an urgent part of the energy-saving and carbon-reduction consensus of all countries. The main concept of green building is "sustainable development", and each stage needs to conform to the principle of environmental friendliness. The birth of green building is actually closely related to the environmental protection issue that the whole world is paying attention to.

With the pressure of international net-zero emissions and the clarion call for carbon tariffs in Europe and the United States, countries have formulated relevant policies to devote themselves to energy conservation and carbon reduction.

The demand for renewable energy is increasing day by day. Faced with the instability of wind energy and solar energy, energy digitization can increase the productivity and availability of green electricity, such as using algorithms and blockchain technology to reduce consumption and improve flexibility.

The green economy is a necessary trend for the global status quo. Governments must also fundamentally reform their policies. It is not easy to achieve this goal, but if we want to move towards sustainable development, the green economy will become key.
