Industry highlights
The policy strongly supports green buildings, which is an important starting point of building energy conservation policy (Finance Associated Press)
Recently, the Ministry of housing and urban rural development issued the "14th five year plan" for building energy conservation and green building development. Previously, the Ministry of housing and urban rural development issued the full text of the mandatory national standard general code for building energy conservation and renewable energy utilization, which will be implemented from April 1. The plan requires that by 2025, the energy-saving transformation area of existing buildings will be more than 350 million square meters, the construction of ultra-low energy consumption and near zero energy consumption buildings will be more than 50 million square meters, and the proportion of prefabricated buildings in new urban buildings in that year will reach 30%.
According to China State Construction Engineering Corporation Limited(601668) Energy Conservation Association, the energy consumption in the construction operation phase accounts for 21.7% of the total national energy consumption. Building energy conservation and emission reduction under the dual carbon target is imperative. BIPV (photovoltaic building integration) represents the development trend of green buildings and has become the direction of strong policy support. Industry insiders believe that two programmatic plans and specifications have been issued one after another, the high-quality and green development in the field of building materials has entered the fast lane, and the fields of building energy conservation and building photovoltaic are important starting points of building energy conservation policies.
