03 "Trade-in for New": Drives the Green Transformation of Existing Buildings

As one of the core forces in the green and energy-efficient building industry chain, Greensee Doors and Windows vigorously promotes the building retrofit model for second-hand housing upgrades. Compared with new house decoration and luxury apartment upgrades, second-hand housing renovation sets higher requirements for the quality of home-building materials and services. In the field of home renovation for old houses, Greensee Doors and Windows' high-end system window and door sub-brand—GenAmo System Windows and Doors—has launched the “24-Hour Window Replacement Campaign,” which allows for window replacement without the need to move out or damage existing decoration.

At the same time, Greensee Doors and Windows has developed exclusive customized retrofit solutions for various types of projects such as existing building renovations, urban old community upgrades, and comprehensive community constructions. These solutions involve replacing existing low-performance doors and windows with higher-performance ones that meet the current national standards. With low investment and high returns, these initiatives significantly promote the recycling industry and the circular economy, bringing remarkable economic and social benefits.

Digital intelligence empowers the creation of high-quality windows, and sincere craftsmanship paints a magnificent chapter. Greensee Doors and Windows being specially recommended by the Changsha Municipal Housing and Urban-Rural Development Bureau at this national conference platform is an affirmation of the enterprise's long-term commitment to technological innovation, and its dedication to intelligent manufacturing and green development. As an advanced model nurtured by Changsha's intelligent construction, Greensee Doors and Windows will continue to be driven by technological innovation, take green and low-carbon development as its responsibility, and contribute core strength to building a more energy-efficient, livable and sustainable urban future.
