At present, we face grave difficulties in achieving the goal of energy conservation and emission reduction. In China, energy consumption related to engineering construction accounts for more than 40% of the total social energy consumption, and this value is still increasing at a rate of one percentage point per year. According to the statistics of the Ministry of Construction, nearly 2 billion square meters of new housing are being built in urban and rural areas every year, and over 80% of such housing are high-energy buildings. Moreover, of the nearly 40 billion square meters of existing buildings, more than 95% are high-energy buildings. Without accelerating economic restructuring and changing growth patterns, resources will soon be unable to meet demands, environmental accommodation will become limited, and social tolerance will drop, ultimately causing the economic development to become unsustainable. Only by pursuing economical, clean, and safe development can we achieve sound and rapid economic development. Meanwhile, greenhouse gas emissions have caused global warming, which is a serious concern for the international community. Further strengthening energy conservation and emission reduction is also an urgent need to address global climate change.
