In response to the pressing need for carbon-neutral solutions in the built environment, the "Second Skin" for Buildings project pioneers innovative retrofitting techniques aimed at enhancing energy efficiency and reducing carbon emissions. This transformative effort addresses the challenge of retrofitting existing buildings by introducing a revolutionary second-skin retrofit approach. By leveraging advanced technologies such as GIS, BIM, and 3D scanning, alongside advancements in modular construction and solar technology integration, this project aims to revolutionize urban sustainability. Through precise spatial analysis and strategic retrofit planning, the project offers a promising pathway toward sustainable urban development, emphasizing the importance of environmental stewardship and climate action in the built environment.
