With China's increasingly stringent building energy efficiency standards for windows and doors, the production model of the window and door industry is undergoing transformation. System windows and doors, which integrate the performance of components, are thus seen as a direction for the industry's development.
"Low carbon" was the theme of the Copenhagen Climate Change Conference at the end of 2009. At the conference, countries introduced their respective energy conservation and emission reduction targets. China pledged to reduce its carbon dioxide emissions per unit of GDP by 40%-45% by 2020 compared to 2005, incorporating this as a binding target into its medium- and long-term national economic and social development plan. This means that energy-saving measures must be taken in all economic sectors. Building energy consumption already accounts for 40% of total societal energy consumption; and window and door energy consumption accounts for 45%-50% of building energy consumption and 15%-20% of total societal energy consumption. Windows and doors are a component of building energy loss, and the replacement of old windows and doors with energy-efficient ones is a trend.
Therefore, it is necessary to improve the thermal insulation effect of windows and doors in all aspects. In the development of window and door technology, high-performance system windows and doors from Europe have attracted attention due to their technical characteristics.
Looking ahead, the window and door market may develop towards green energy saving, smart interconnection, and personalized customization. The market application of system windows and doors may increase, and the renovation of existing houses and high-end customization may become the growth areas of the industry.
